Music you never knew was there.


Dbx






Suppose you're in an art museum and find half of every picture covered with masking tape.

Outrageous? Sure. But you listen to music the same way.

Crescendos and pianissimos are sandwiched and crowded towards the middle.

The villains are the recording and broadcast processes--tapes, records, AM/FM. They have limitations that sacrifice almost half the dynamic range--the range between quiet and loud--of all the music you hear.

But now there is a way to unlock these processes ... so your system can let you hear what you would actually hear at a live performance.

A few words about an amazing instrument The human ear. It outperforms the best studio tape recorder by about 50%. The least sound it can hear is about 0dB of sound pressure level (or decibels, which is a scale for measuring the loudness, or quietness, of sound). The loudest sound it wants to hear is around 130dB. This gives it a dynamic range--the sound space if you will, between quiet and loud--of about 130 dB.

The professional studio tape recorder has a dynamic range of only about 58 dB. And there lies the problem. A professional tape recorder "hears" a lot less than you do.

The problem--compressed sound How does a recording engineer squeeze a musical performance with a range of 100 dB into a recording range of 58 dB? He can restrict the loud and quiet passages. Or he can squeeze.

Push the quiet parts up, making them louder.

Then push the louds down, making them more quiet. Until everything is compressed into a 58 dB range.

Who cares? Your ears. They know what a live performance is like. So they can tell when compression blurs the sharp edge of percussive attacks, muddles the contrasts between quiet and loud instruments, and sacrifices definition. And the more compression, the more the music sounds flat and pinched, almost two-dimensional.

The solution--decompressed sound Reverse the process. Simply by making quiet sounds more quiet and loud sounds louder, the way they are in a live performance, your system can pack your music with vitality and excitement.

Realism, if you prefer. This is called expansion. The contrast between quiet and loud becomes startling, and musical performances approach the electrifying intensity of a live concert hall. The device that achieves this is called a dynamic range expander.

A few words about another amazing instrument The dbx 3BX dynamic range expander. It's more than a state-of-the-art expander. It is the state of the art. Other companies' expanders operate only on a portion of the dynamic range and damage true musical perspective. The dBX, however, Its a true linear expander. It uniformly expands the dynamic range of all levels and all frequencies. Key elements are a patented rms detector which accurately senses the dynamic content of your music, and a voltage controlled amplifier which it instructs to increase or decrease level. Moreover, the 3BX separates the frequency spectrum into three bands and expands each individually. By knowing at any given instant which bands require expansion, the 3BX achieves stunning clarity and musical depth.

It's almost like having a Hi-Fi system for each instrument Listen to music through a 3BX. What you're hearing is actually better than the broadcast source--better than the tape, better than the record, better than the FM signal. Definition is breathtaking. You'll hear the sharp attack of a brass section. The soft brushwork of a drummer.

Every nuance and texture of a symphony string section will have incredible presence.

And crescendos will build with conviction and amazing depth.

You not only hear what you're getting, you see what you're getting The more you listen to the 3BX, the more you'll appreciate it. You can set the linear expansion for anything up to 50% more dynamic range. There is a pre/post switch for taping and/or listening. But the most visually intriguing part of the 3BX is the LED indicator bank for each of three frequency bands which shows you just where and how much expansion you're enjoying. You'll see the board light up when a double forte note jumps out of the speaker. Or with the sudden shout of a rock singer. Or when you hear a string section and it feels almost thick with depth and you not only become more aware of the harmonics, but are able to pick out individual instruments. And the transition level control lets you center the program on the display, so you can see exactly what is going on.

The only component you won't have to upgrade It will make no difference how modest, or expensive, your system is. The 3BX produces dramatic results with any system because it attacks the bane of all systems--the program source. So while you upgrade your system, the DBX upgrades what goes into your system.

Be prepared for a rather pleasing side effect The loss of about 20 dB of noise inherent in most records, tapes and FM broadcasts. As a matter of fact, noise approaches inaudibility.

There's more to hear After you've heard the 3BX, listen to the dbx 118 linear dynamic range enhancer. It not only expands the dynamic range of sound, like the 3BX, for better listening, it can also compress the dynamic range of sound for background music for the home and special recordings. And if you're into copying your tapes and records onto cassette or open reel, you'll want the dbx 128.

It makes tape copies that sound better than the records. It has two separate signal processing units in one. The first is a dynamic range enhancer for expansion or compression of sound sources.

The second is a dbx II tape noise reduction system which allows wide dynamic range material to be recorded on tape with no audible noise added by the tape recording process.

A challenge What we say here is nothing compared to what your ears will tell you. As a matter of fact, we'd like to offer you a friendly challenge. If you think your system is so good it can't be improved upon, drop in on your dbx dealer and listen to a similar system with a dbx expander. The difference will startle you. And that's a promise.

The one alternative to separates: The Yamaha CA-2010 Integrated Amplifier.



The Head Amplifier. Discerning music lovers all over the world are discovering the transparent highs and extended frequency response of the moving coil phono cartridge. While other manufacturers require the addition of an expensive preamp or step-up transformer to boost the low output signal, Yamaha included a special head amplifier in the CA-2010. It's available with the flip of a switch on the front panel. And to help you get the most out of moving magnet cartridges, there's a 3-position phono impedance selector.

The Preamplifier. To assure exact, repeatable bass and treble settings, the controls are precision calibrated in ½ dB steps. Dual turnover frequencies for both ranges double the versatility of these accurate tone controls. Completely independent Input and Output Selectors let you record one source while listening to another. And the power meters are easily switched to REC OUT readings in millivolts, so you can monitor the actual output level to your tape deck for cleaner, distortion-free recordings.

The Power Amplifier. 120 watts RMS, with no more than 0.03% THD 20Hz to 20, 000Hz into eight ohms.

For tighter, cleaner bass response, the amplifier can be switched to DC operation.

Class A operation is switchable on the front panel, delivering 30 watts RMS, with no more than 0.005% THD 20Hz to 20, 000Hz into eight ohms.

The twin power meters are fast-rise, peak delay-they can track even the briefest of transient bursts. Plus they can respond to levels from 1mW to 316W (into eight ohms).

Real Life Rated! The specifications of the individual components of the CA-2010 are superior to many separates. Individual specifications alone, however, can't possibly reflect actual in-system performance. That's why Yamaha measures overall performance from phono in to speaker out, rather than at designated points along the signal path. Furthermore, we measure noise and distortion together over a broad output range, rather than individually at the optimum output.

Our Real Life Rated measurement is called Noise-Distortion Clearance Range (NDCR). On the CA-2010, NDCR assures no more than 0.1% combined noise and distortion from 20Hz to 20kHz at any power output from 1/10th watt to full-rated power.


Superb tonality from a musical tradition of technical excellence. The tonal accuracy of our audio components is referenced to the same standards used to evaluate the tonal accuracy of our world-renowned musical instruments. The result is a rich, clear tonality that is unknown elsewhere. You really must hear it.

You really must hear the same resolutely accurate music reproduction available from all four Yamaha Integrated Amplifiers and four superb tuners. All are made to a single standard of excellence--a standard rooted in a 90-year tradition of musical perfection.

To get a superb performance, you need a precision machine.

To command a great performance, a cassette shell and cassette tape must be engineered to the most rigorous standards.

Which explains why we get so finicky about details. Consider: Precision Molded Cassette Shells--are made by continuously monitored injection molding that virtually assures mirror-image parallel match. That's insurance against signal overlap or channel loss in record or playback from A to B sides. Further insurance: high impact styrene that resists temperature extremes and sudden stress.

An Ingenious Bubble Surface Liner Sheet commands the tape to follow a consistent running angle with gentle, fingertip-embossed cushions. Costly lubricants forestall drag, shedding, friction, edge-wear, and annoying squeal. Checks channel loss and dropouts.

Tapered, Flanged Rollers--direct the tape from the hubs and program it against any up and down movement on its path to wards the heads. Stainless steel pins minimize friction and avert wow and flutter, channel loss.

Resilient Pressure Pad and Holding System spring-mounted felt helps maintain tape contact at dead center on the head gap. Elegant interlocking pins moor the spring to the shell, and resist lateral slipping.

TDK Cassettes--despite all we put into them, we don't ask you to put out a lot for them. Visit your TDK dealer and discover how inexpensive it is to fight dropouts, level variation, channel loss, jamming, and other problems that interfere with musical enjoyment.

Our full lifetime warranty is your assurance that our machine is the I Five-Screw Assembly-, foi pi actually guaranteed warp-free mating of the cassette halves. Then nothing-no dust of tape snags--can come between the tape and a perfect performance.

Perfectly Circular Hubs and Double Clamp System--insures there is no deviation from circularity that could result in tape tension variation producing wow and flutter and dropouts. The clamp weds the tape to the hub with a curvature impeccably matched to the hub's perimeter.

Head Cleaning Leader Tape--knocks off foreign matter that might interfere with superior tape performance, and prepares the heads for.. , Our famous SA and AD Tape Performance-two of the finest tapes money can procure are securely housed inside our cassette shells. SA (Super Avilyn) is the tape most deck manufacturers use as their reference for the High (CrO2) bias position.

Discwasher


THE SUPERIOR RECORD CLEAN CAUTION

MADE IN U S A

THE RED BOTTLE General Need: Tests by the Discwasher Labs show that fingerprints are absolutely not totally removed by "dry cleaning in any form, either brush or adhesive rollers. Long term record care requires the complex integration of micro-dust pick-up (not spreading around), with removal of chemical contamination such as fingerprints; plus an in-process reduction of static charge so that dust particles are not immediately sucked back onto the surface. And all of this must be done without leaving a residue.

D3 fluid, used with the Discwasher System for capillary removal of fluid/contamination achieves the results required for record survival. But the hidden requirements of a record cleaner are much more complex than integrated function alone.

Chemical Integrity: The trick is not to simply clean-but to c can with vinyl safety and extremely low "solute load" or fluid content. D3 is a solution that typically has half the dry weight residue of tap water and about one-fifth the median for other "record cleaners". D3 typically has the dry weight residue of distilled water sold in drug stores-and yet D3 has an activity in surface tension reduction/fingerprint removal that is greater than any fluid with twice the solute load of D3.

D3 fluid contains a complex blend of buffered surfactants conjugated in the labs of Discwasher, Inc.

These provide cleaning "activity" against real-world record contamination, like fingerprints and airborne oils. But not against artificial "test conditions" of mineral oils and sheep wax (lanolin). Because if D3 removed waxes and oils of this nature, then D3 would also begin to soften critical vinyl stabilizers which are essential for record survival under the incredible heat and pressure of a tracking audio stylus. Alcohols and many cleaners pull stabilizers and age vinyl.

Some cleaning fluids contain large molecules of fatty acids to "float" dirt-but these "molecules" positively stick to vinyl and are literally a dust trap.

D3 fluid does not dramatically reduce static charge forever. The only liquid that can is one which leaves a coating. But D3 does reduce static charge during cleaning (using 3 drops on the Discwasher brush), and actual static voltage is reduced during playback to about one-half the normal levels.

The Discwasher "Systems Approach": Any cleaning fluid, when left on the record, only spreads out contamination. With three drops of D3 o a the special directional micro-fibers of the Discwasher brush, dust is lifted out of the grooves, without "follow up" or adhesive oxide removal of the vinyl.

In addition, the Discwasher System wicks up D3 fluid plus suspended contamination. The fluid is drawn deep into the absorbent backing of the Discwasher brush. No liquid, dustor contamination "dries back" when the system is properly used. The "systems approach" of Discwasher includes a hand-rubbed, milled walnut handle. Something to outlast plastic wonders and out-perform everything else. Your records can't do better than the Red Bottle inside the "system”.

"Sure, they'll know Grand Master sounds better. But they won t know how much beter unless they actually test it."

Roy Cicala, Recording Engineer, The Record Plant, New York City

We asked Bob Liftin and Roy Cicala if audio buffs are ready for a tape as sophisticated as Grand Master for use at home.

They should know. Both are nationally famous recording engineers who've been using Grand Master Studio Mastering tape since it first came out in 1973.

Bob said, "Sure they're ready.

Grand Master's dramatic 4 to 8 dB improvement in signal-to-noise ratio allows a guy to hit the tape 3 to 6 dBs harder and still get better distortion figures." Roy wasn't so sure. "Of course, Grand Master's lower distortion and higher output mean a lot to pros.

But I wonder how many home systems are sensitive enough to pin point the improvement. Unless you run side-by-side tests with identical equipment, you can't tell how much better it is." Noting the difference of opinion, we asked other top engineers.

Most agreed with Bob.

(Sorry, Roy.) They felt the uniform response of Grand Master would allow a more realistic playback. And yield a cleaner sound as a result.

Which confirmed what we thought all along: You're ready for a very sensitive, high-output, low distortion tape to use at home.

GRAND MASTER BYAMPEX.

WE THINK YOU'RE READY FOR IT

So now there are 3 new versions of Grand Master. An exciting cassette with lots of exclusive precision features. A completely redesigned 8-track cartridge. And a True-Track tape guide system for accurate azimuth control Head-cleaning leader professionally constructed quarter-inch open reel as well.

So now it's up to you.

For the first time, you can actually buy the kind of recording tape only the pros could get their hands on.

We think you're ready for it.

Even if Roy Cicala isn't sure.

Missa Solemn is... Fidelio...and much more! Time-Life Records invites you to a perfect marriage of the arts of composing and performing great music: Beethoven's symphonies conducted by Herbert von Karajan.

Beethoven, the arch-romantic-his music (like his tortured soul) surging with fiery emotion. von Karajan, called "the space-age maestro"--cool, precise, methodical, whether on the podium or at the controls of his private jet.

Two more different geniuses are hard to imagine. Yet the product of their "collaboration" is sheer magic-as you can now discover in a free audition of Volume I of the Beethoven Bicentennial Collection.

Hear von Karajan and the Berlin Philharmonic play the first 6 symphonies--free for 10 days.

In this elegant boxed set of five 12" LP stereo discs, recorded in Europe by the famous Deutsche Grammophon, you will hear the stirring Leonore Overture No. 3, as well as six complete symphonies, among them:

SYMPHONY NO. 3 ("Eroica"). A heroic struggle waged in sound--described by one critic as "the greatest single step by an individual composer in the history of music SYMPHONY NO. 5. The wild jubilant conclusion is all the more electrifying because of the brooding drum taps and weeping violins preceding.

SYMPHONY NO. 6 ("Pastoral"). An image-filled trip to the country-complete with nightingale (flute), cuckoo (clarinet) and quail (oboe).

And this is only the beginning. If you decide to sub scribe, you will enjoy free auditions of further volumes in this definitive Beethoven collection. They include the remaining symphonies, Nos. 6-9, again by von Karajan... the celebrated "Moonlight" and turbulent "Apassionata" piano sonatas... the fascinating "Triple Concerto" for piano, violin and cello...

Sonus


If you've invested $500 or even $5000 in your high fidelity system, read on. Because what we have to say can have a lot to do with the quality of sound you're hearing.

Unfortunately, one of the most over looked components in a fine sound system is the cartridge. And all too often, it can be the one place where you skimped on quality. (Out of sight, out of mind, as they say).

We sincerely believe that an investment in a Sonus cartridge will truly surprise you with the way it improves the quality of your record reproduction. The analytical quality of the Sonus brings out the inner voices of complex musical passages clearly and cleanly. Listening fatigue disappears.

And a Sonus introduces no extraneous coloration of its own.

But what we're talking about is said even better by Sonus owners. "Excellent clarity," "more fulfilling sound," "open, airy 3-D sound," "superb depth and definition," "clean, accurate and transparent sound," are typical of thousands of enthusiastic comments we have received from owners of Sonus cartridges.

Make sure your cartridge matches up to the rest of your system. Write us for further information and the name of the Sonus dealer nearest you.

Maxell



It's hard to find a $1,000 tape deck that doesn't use Maxell.

Or a $100 tape deck that shouldn't.

If you spent S 1000 on a tape deck, you'd be concerned with hearing every bit of sound it could produce.

That's why owners of the world's best tape decks use Maxell more than any other brand.

But if you're like most people, you don't own the best tape deck in the world and you're probably not using Maxell. And chances are, you're not hearing every bit of sound your tape deck is capable of producing.

Whatever you spent for your tape deck, it's a waste not to get the most Maxell out of it. So spend a little more and buy Maxell.

Maxell. You can think of us as expensive tape. Or the cheapest way in the world to get a better sounding system.

FUJI


The specifications of your cassette deck may look outstanding. But its actual performance--the quality of your music reproduction--can only be as good as the tape you use. To ensure optimum performance, all of the time, you need Fuji cassettes.

Consistency. Cassette tape performance can vary with each cassette tape. Consistent performance, however, can only be guaranteed by a company which produces all the elements that go into their tape. A company like Fuji. We make our own base film and our own binder material. We produce our own oxide and do our own coating. Stringent quality control, including factory testing of each cassette, further assures you of total reliability and highest fidelity, always.

Versatility. The new Fuji FX-I 120pts normal-bias formulation is ideal for use with home, portable and car decks; because Fuji FX-I is completely compatible with every normal-bias machine.

Bias Acceptability. To ensure perfect compatibility between your machine's factory-set bias and your tape, you need a tape with a wide range of bias acceptability. Like the new Fuji FX-II 70ps Beridox cassette. Its bias latitude is much greater than most other high-bias formulations.

Wow and Flutter . The friction created by conventional cassette housings may adversely affect the wow and flutter performance of your cassette machine. So Fuji designed a new housing for the FX-I and FX-II tapes. With unique Teflon coated waffled slip sheets, convex guide rollers (for more accurate tracking) and improved pressure pad, the new Fuji housing substantially reduces friction.

So to get the best possible performance from your cassette machine, to make your music sound clean, clear and crisp, visit your Fuji dealer today. Tell him you want to upgrade your hi-fi. Tell him you're ready to Fuji-Fi.

Introducing The DM Factor.

Dual Monaural construction. Exclusively Mitsubishi.

It means inside our stereo preamplifier are two perfectly matched mono preamplifiers.

Just like our dual monaural power amplifiers.

Just like your ears.

It means Mitsubishi has achieved more than stereo.

But inter-channel separation at more than 80dB at 20kHz.

For separation 30dB more than conventional designs.

For THD at less than 0.002% from 20Hz to 20kHz.

For effective elimination of leaks, crosstalk, any influence able to distort the stereo image. In both the depth and breadth of the image.

Our new preamplifier was also developed to effectively handle the moving coil cartridge. For a signal-to-noise ratio of-77dB. Unheard of in any other preamplifier.

Introducing our new frequency synthesizing tuner.

With new capabilities, new features, new design.

With THD in stereo at barely 0.08% at 1 kHz. Conservative, at that. With switched selectivity for uncompromising reception. With digital read-out. With LED's to deter mine signal strength and precise tuning. With an un canny ability to zero in on the quietest signal.

And along with unique electronic engineering, Mitsubishi offers unique mechanical engineering.

Like The Docking System.

It means preamplifier can be linked with amplifier neatly and compactly. Without a myriad of crossed wires.

But no matter what we tell you, the truth is, nothing will tell you more about our audio equipment than your own audio equipment.

So, use your ears, and by all means compare.

Compare the difference The DM Factor makes.

Compare the convenience The Docking System makes.

Compare the capabilities of our new tuner.

And you'll know why Mitsubishi made them part of The System.

The only high performance audio system with one name, one look, one warranty, one standard: what comes out must be as real as what went in.

Because reality is what it's all about.

Shure


fact: the IV does more...

much more! new! Shure V15 Type IV—Super Track V Era IV begins! The new Shure V15 Type IV phonograph cartridge is an altogether new pickup system that exceeds previous cartridge performance levels by a significant degree. It systematically solves not one, but several problems prevalent in modern disc sound reproduction:

Demonstrably improved trackability across the audible and subaudible range at ultra-light tracking forces The V15 Type IV has a new stylus assembly design for dramatically increased trackability. The effective stylus mass has been lowered significantly by utilizing a telescoped shank structure and a new lightweight high-energy magnet.



The reduced effective mass of the new structure helps improve trackability in the critical mid and high frequencies. A newly designed two-function bearing system has been independently optimized for low frequencies and for high frequencies so that trackability is enhanced across the audio spectrum.

The shaded area at right in the Trackability chart on preceding page represents recommended theoretical limits of record cut ting velocities. However, the scattered points are the "hottest" recorded velocities actually measured on today's difficult-to-track records. The new V15 Type IV tracks far more of the "hottest" points at a low stylus force than any other existing cartridge! (The curve shown is for 1 gram tracking force. By increasing this to 1 1/4 grams, even more of these points--which encompass virtually all records produced thus far--will be tracked.) Dynamically stabilized tracking that overcomes record warp problems Our war on warp ...

THE V15 TYPE IV

The warp problem Note the shaded area (at bottom left of the Trackability chart at left) which represents actual warp signals found on records, and the revolutionary subaudible warp trackability characteristics of the SUPER TRACK IV. Reactions of the playback system to these very low frequency warps (between 0.5 and 8 Hz) existing on virtually all recordings can result in gross changes in the distance between the cartridge and the record. This distance change alters the stylus tracking force and the vertical tracking angle and can result in groove skip ping, cartridge bottoming, signal wow, and even amplifier and/or speaker overload.

Trackability at all frequencies is diminished by these warp-caused changes in tracking force! Also, at some very low frequency (from 5 to 15 Hz), the tone arm-cartridge combination has a resonance frequency. When this resonance frequency is excited by the warp, all the above symptoms are intensified.

The Super Track IV total design solution:

A viscous-damped Dynamic Stabilizer on the V15 Type IV combines with a new stylus assembly to minimize or completely eliminate warp-related problems. It raises the arm-cartridge resonance frequency and attenuates the arm-cartridge system resonance effect.

An electrostatically-neutralized record surface

CONDUCTIVE FIBERS CHARGED GROUND DISCHARGED RECORD

FRONT VIEW

The static problem:

Static charges are omnipresent and un evenly distributed on all records. These charges can attract the cartridge unevenly and change the arm-to-record distance, the vertical tracking angle, and stylus tracking force. The result is wow and flutter. Also, static discharge through the stylus and amplifying system can be a cause of annoying pops and clicks.

The Super Track IV total design solution:

Electrically conductive fibers in the Dynamic Stabilizer of the V15 Type IV ride on the surface of the record and continuously sweep the grooves just ahead of the stylus. This picks up the static electricity and discharges it to ground, much like a miniature lightning rod. The record surface is thus electrically neutralized. The static charge is prevented from affecting the arm-to-record distance, or from causing static noise in the system. Discharging the static stabilizes tracking force during the entire record playing process and does away with the electrostatic attraction of dust to the record surface.

In addition, the conductive fibers effectively sweep the record surface to remove loose dust and lint.

The Hyperelliptical nude diamond tip con figuration of the V15 Type IV represents a significant advance in tip design for stereo sound reproduction. As the above figures show, its "footprint" (represented by the black oval) is longer and narrower than the traditional Biradial (Elliptical) and narrower than long-contact shapes (such as the Hyperbolic). This results in an optimized tip-groove contact area and dramatically reduces both harmonic distortion (white bars in graph) and intermodulation distortion (black bars).

Because we think a good music system should be heard, And seen.

People who are into good music reproduction are proud of their high fidelity component system. They like to put where everyone can see as well as hear it. And rightfully so, because visually, todays components are a tribute to the finest expression of contemporary design.

That's why JVC is introducing its series of Music-towers.

They’re br people who like to display their JVC component system in one place. Or any place.

To meet just about any requirement for a JVC component system, our handsomely styled Mus give you the opportunity to select the JVC components you want: anything from a basic system (receiver, turntable, cassette deck, speakers) to one that accommodates a total system of separate components

Take ourLX-3000 MusicTower This strikingly styled unit with gleaming walnut veneer sides, is designed for nineteen-inch rack-mounted components, and can house JVC's Professional Series.

Each component represents the finest JVC offers.

And the great thing is that it's easier than ever to make the proper interconnections after each component slides securely into place. Then, because JVC believes distractions belong in the back, not the front, all interconnecting wires vanish from sight within each of the two vertical supports.

You can even move the whole works from one listening area to another; the LX-3000 Music-Tower glides smoothly over any floor surface on heavy duty casters that lock into place. This JVC MusicTower takes the center spotlight in any listening room.

 

JVC-We build in what the others leave out.

THAT NEW BLACK MAGIC.

TEAC


So it's got an expensive new look that separates it from every deck in its class. Nice.

But is that reason enough to call it magic?

No.

But this is: generally speaking, over a quarter century of TEAC engineering is wrapped up in the A-103. Specifically speaking, the A-103 boasts an innovative design that re places a maze of wires and circuit boards with a single circuit board. That's one reason.

When you press the Eject button, your cassette doesn't pop out at you like a de ranged toaster. It's cushioned, and works slowly and smoothly for longer deck life.

That's two reasons.

Built-in Dolby circuitry High Density Fermaflux head, frequency-generated servo-controlled DC motor, separate level controls, wide dynamic range, and switchable bias/equalization.

Reasons three through eight.

But how do we offer all these things (and more) in a deck that costs as little as the A-103? That's the real magic!

Technics introduces three ways to achieve the one ideal:

Waveform fidelity


To achieve waveform fidelity is an achievement in itself.

But how Technics audio engineers accomplished it is an even greater achievement.

Like the unprecedented use of two automatically switchable IF bands in the ST-9030 FM tuner. A narrow band for extra-sharp selectivity. And a wide band for extra-high S/N and extra-low distortion. But List as incredible is a pilot-cancel circuit which Technics invented for optimum high-end response. Even the basic tuning function in the ST-9030 is unique. Like an 8-ganged tuning capacitor for outstanding reception.

The engineering in the SU-9070 DC pre-amp is similarly unique. There's a built-in moving coil pre-amp with-157 dBV noise voltage. A moving magnet pre-amp with an extremely high S/N of 100 dt3 (10 mV input). Direct-coupled circuitry to keep distortion at a minimum of 0.003% (rated THD). What's more, the SU-9070 has inputs for three tape decks.

Finally there's Technics SE-9060 amp. It's DC like our pre-amp. Has a frequency response of 0 130 kHz ( + 0,-1 dB). And a strapped- circuit for more than double the power in a multi-amp system.

Compare specifications and prices. And you'll realize there's no comparison for Technics waveform fidelity.

SE-9060. POWER OUTPUT: 70 watts per channel (stereo), 180 watts (mono) min. RMS into 8 ohms from 20 Hz to 20 kHz with no more-bon 0.02% to-al harmonic distortion. S/N: 120 dB (IHF A).

Technics. A rare combination of audio technology. A new standard of audio excellence.

Until now, that's all you've had to lay your record on when you wiped, sprayed or buffed it.

Now you've got some--The pad protects one side of your record while you're working on the other The pad holds the record gently in place for buffing or wiping.

thing that takes care of one side of your record while you're working on the other side. It's non-conductive to resist picking up particles from dirty records. It's not a fabric, so it has no lint to spread around. And it's non abrasive to avoid scratching and slipping when you're buffing.

Its ingenious channels give you another advantage. They collect any excess fluid so it won't run over to the other side of your record-or onto your furniture.

Wash off your record care work pad, when you have to.

Use it as you're meant to, and your records will never take another beating.

LUX


We're rather well-known for our expensive amplifiers and tuners.

Now we'd like to be known for our less expensive ones.

When LUX Audio products were introduced to the U.S. in late 1975, we had already played a leading role in Japan electronics for more than five decades. And our audio components had enjoyed an enthusiastic following in Asia and Europe for many years.

Thus, unlike the typical "new" brand, LUX had available a wide array of integrated and power amplifiers, preamplifiers and tuners. Eighteen models in all. Our problem was deciding which to introduce first.

We chose our top of the line power amplifier, the M-6000. Its enthusiastic reception encouraged us to follow with our other state-of-the-art products, such as the L-100 integrated amplifier and the C-1000 preamplifier.

These superb components combined performance, styling and precision in a manner new to the U.S. audiophile. They prompted one audio publication to state: "Almost overnight, the name 'LUX Audio' has earned itself a place of Luxman T-88V AM/FM stereo tuner. Our least expensive tuner, yet includes FET front end with four-section tuning capacitor.

Linear-phase ceramic filters in IF section. Features include FM interstation-noise muting, variable output level control and oscilloscope jacks for viewing multipath distortion, etc. Usable FM sensitivity; 2 microvolts (11.2 dBf) IHF and 2.8 microvolts (14.1 dBf) for 50 dB quieting. Stereo separation: 43 dB at 1,000 Hz. $345.00 respect in the hi-fi marketplace." That was fine. Not so fine, however, was our resulting reputation for being very expensive. Thus, many audiophiles were deprived of enjoying LUX quality and performance simply because they were unaware of our less expensive products.

We're now rectifying that. The units shown below are representative of our more moderately priced components. The differences between them and our top models are more a matter of power or flexibility than any variation in quality. You'll see that even our lowest priced units have specifications any manufacturer of fine components would be proud of.

So, if some of the engineering "indulgences" of our top units aren't really necessary to you, you can still enjoy the sonic excellence that distinguishes LUX components... because now you know about our moderate-priced components. Your LUX Audio dealer will be happy to spend as much time as you need helping you to appreciate them.

Luxman L-80V integrated stereo amplifier. 50 watts minimum continuous power per channel, with total harmonic distortion no more than 0.08 per cent, both channels driven simultaneously into 8 ohms, 20 to 20,000 Hz. Frequency response, 10-50,000 Hz, within 1 dB. Phono Sill better than 77 dB (re: 10 mV input).

Bass and treble controls each have 3 turnover frequencies; high and low filters each have 2 cut-off frequencies. $475. (Luxman L-85V, similar except 80 watts per channel, $765.) LUX Audio of America, Ltd.

Notary Public Certified Performance Series

Introducing the Certified Performance Series Receivers:

You'll know what you're buying. You'll see it in writing.

Why specifications are less than specific.

An inevitable by-product of mass production is that there will exist, on a unit-to unit basis, significant variations from the "target" level of performance.

You can get a general idea of what your set can do from the manufacturer's posted specs. A general idea. But we at Sherwood feel that no specs are as important as the specs of the unit you end up buying.

With the introduction of the CP Series Receivers, Sherwood has minimized the chance of sub-standard performance-thanks to a practice we've introduced into mass-production: individual fine-tuning of each unit.

Critical areas of performance of both the tuner and the amplifier sections are evaluated. And, throughout the process, each receiver is "tweaked"-fine aligned for peak performance. Given, in short the special treatment that typically is extended only to "showpiece" units.

So, we predict you’ll find that the Sherwood receiver you're paying for doesn't simply meet the posted specs of its competition, but exceeds them. Often by a considerable margin.

SHERWOOD

Does certification add to the cost of each receiver? Undeniably. But we at Sherwood are convinced that the impact on overall value is greater than anything else which could be done to the product at comparable cost.

Attached to the carton containing the receiver you'll find a notarized document attesting to its actual performance levels.

It will prove that we've done everything possible to make it sound its best.

Well be there first.

ONE GOOD THING

LEADS TO ANOTHER.

When it comes to a super-powered receiver, people know a good thing when they hear it.

That's why our KR-9600 is one of the most popular receivers in its category.

For less than $750* you get 160 watts per channel, minimum RMS at 8 ohms, from 20-20,000 Hz with no more than 0.08% total harmonic distortion. With all the features and performance you'd expect from our top of the line receiver.

But let's face it. A lot of people don't need all that power. That's why we developed the KR-4070.

It's got 40 watts per channel, minimum RMS at 8 ohms, from 20-20,000 Hz, with no more than 0.1% total harmonic distortion. (That's correct. 0.1% THD.) Plus all the features most people need.


But what's incredible, is that you can buy it for less than $300. Depending on how much power you need, either receiver will give you more performance for less money than you thought possible.


Because at Kenwood, we think you can't get too much of a good thing.

Critics and audiophiles agree the listening quality of the DQ-10 is unexcelled. What accounts for its superb performance?

Time

Much credit for its smooth coherence must be given to the precisely matched transient characteristics of the five drivers. And, a good deal has been written about the DQ-10 and its extraordinary solution to the problems of time de lay or phase distortion. It is not surprising that other high quality speaker designers have followed suit in offering their versions of time delay correction.

...and Time Again The real "secret' to the unprecedented performance : the DQ-10 lies in Jon Dahlquist's patented method for reducing (*fraction, a more audible and destructive form of time distortion. The separate baffle plate on which each driver is mounted is dimensioned to minimize diffraction in the frequency band in w aich it operates.


Thus. the effect of thesoend we hear is that of a driver mounted in free space, without obstructions or surfaces to distort the original sound source.

It can be said that the DQ-10 eliminates inaccurate reproduction caused by time elements--inertial time delay, and diffraction time delay--distortions that limit the performance of conventional speaker systems.

That's why the more critical listener select the DQ-10.

Time and time again.

Accutrac+6.

Under $100,000.

If you wanted to build your own Accutrac+6, you'd need lots of time. And lots of money.

At least $100,000 for computer circuitry, electro-optic mechanisms and much more.

But you can buy it from us for under $100,000.

$99,700 under to be exact. Because you can buy the Accutrac+6 model 3500 for less than $300! But the most incredible thing about the Accutrac+6 isn't the price tag, it's the features.

Like computerized track selection.

Which in plain English means that you can hear the tracks on each of six records in any order you like, as often as you like.

Even skip the tracks you don't like.

Literally, it's customized listening.

And you never have to touch the tonearm to do it, because the Accutrac+6 is engineered with a computerized "hands-off" tonearm.

In fact, once you close the dust cover you never have to touch the records or tonearm again to hear your programmed selections.

But the brain in the Accutrac 6 is smart enough to do even more. Like protecting your records.

So, instead of dropping your records onto the platter, it lowers them v-e-r-y g-e-n-t-l-y.

That's what we said: it doesn't drop your records. Its Accuglide Spindle is like an elevator.

In fact, just touch the "raise record" key, and it lifts all six records back up into the starting position.

As long as we have you touching the keys, let us tell you how you can control the Accutrac+6 from across the room.

With Accutrac- 6 model 3500R you can control everything from across the room with a full-system remote control transmitter and receiver. There's even remote volume control on model 3500RVC.

No other 6 record system gives you the record safety, convenience and control of the new Accutrac 6. But the truly incredible feature of the new Accutrac+ 6 is its low price. From under $300* for model 3500. So forget everything you know about 6 record systems.

And remember to see the new Accutrac+6. A D It's beyond your wildest dream, yet below what you'd expect to pay. A BSR Comfmni, Accuitrac+0

Why you should consider the new Garrard GT35 if you're thinking Dual or B.I.C.


We'll say it straight out. The new Garrard GT35 is the best all-around turntable anywhere near its price.

Let's do some direct comparing.

Start with the motor. The Dual 1245 features a fine 8 pole, synchronous motor and the B.I.C. 981, a 24 pole, synchronous unit.

The new Garrard GT35 incorporates a servo-con trolled, DC mo tor. Servo control provides absolutely steady speed. The motor, (and thus the rotation of the platter), is immune to fluctuations in house hold voltage or frequency. Len Feldman, writing in Radio Electronics, reviewed it as a "significant breakthrough" superior to the "synchronous motor however many poles it might have!' The GT35 is the only, belt-driven, single/multiple play turntable in the world with a servo-controlled, DC motor.

Chalk one up for the new Garrard GT35.

Now for the tonearm. Remember that the delicate stylus, as it traces the groove, bears the full weight of the tonearm. The heavier the tone-arm, the greater the wear on the record and stylus. Light is right.

The effective mass of the GT35 tonearm (measured with a Shure M95ED cartridge, tracking at 1 1/4 grams) is a mere 20.4 grams. That's lighter than the tonearm of the Dual 1245 at 27.5 grams or the B.I.C. 981 at 25.6 grams. In fact, the new Garrard GT35 has the lightest tone arm of any single/ multiple play turntable.

Chalk up one more for the Garrard GT35.

The Dual, B.I.C. and Garrard all protect your records as only fully automatic turntables can. And all provide the convenience of multiple play. But only the new GT35 boasts the patented Delglide sys tem. Unlike the Dual and B.I.C. automatic mechanisms, Delglide is driven by its own belt and is located directly under the tonearm.

Tonearm control is by simple rotary action. It's no wonder that Radio Electronics said, '!.. the pick-up arm is handled more gently than could new be done by the steadiest of hands' We make this claim: Delglide is the smoothest and quietest automatic system ever incorporated in a turntable--of any kind.

That's still another one for the new GT35.

There's more. The Dual 1245 and the B.I.C. 981 are warranted for 2 years. The new Garrard GT35 carries an unprecedented 3 year warranty. That's our way of underscoring its exceptional reliability.

Finally. The price advertised by the manufacturer. Including the base and dust cover; the Dual 1245 is $240 and the B.I.C. 981, $237. The price of the new Garrard GT35: just $219.95.

The GT35: a "breakthrough" mo tor, the lightest tonearm, the smoothest and quietest automatic system and a 3 year warranty.

Consider the GT35. If you're thinking Dual, or B.I.C. Or Technics.

Or Pioneer. Or Sony. Or... Garrard.

PHASE LINEAR

PHASE LINEAR SETS THE STANDARD FOR HIGH POWER. AGAIN.


Current loudspeaker design theory takes for granted the availability of a high power reserve. An idea once considered frivolous by many. Today it is considered essential for the best possible reproduction of recorded material.

To reproduce a musical peak, a loudspeaker requires up to 10 times the average power being delivered. If the amplifier lacks a sufficient power reserve, it will clip, producing distortion and audibly destroying sonic quality.

The Phase Linear Dual 500-Series Two Power Amplifier is capable of delivering in excess of 505 watts per channel from 20Hz-20kHz into 8 ohms, with no more than 0.09% Total Harmonic Distortion.

That's unsurpassed power for unsurpassed realism.

--- CONVENTIONAL DUAL-300; OUTPUT TRANSISTOR.

The Dual 500 utilizes an advanced design in output de vices to overcome the problems associated with amplifier clipping at realistic listening levels.

A massive rear mounted extruded aluminum heat sink assembly, including a thermally activated forced air cooling system, protects the 36 output devices against overheating.

I Instantaneous indication of output activity is easily maintained with an exclusive 32-segment LED display, while a special 4-segment clipping indicator warns of hazardous overloads. High/Low Impedance Operation modes are automatically or manually activated for increased amplifier efficiency when using low impedance speakers.

Hearing Is Believing.

Jensen


Now, a true state-of-the-art speaker system from Jensen.

The Jensen Separates. We think you'll agree that they're the most technologically advanced car stereo speakers available.

Jensen has finally closed the gap between home" and car stereo reproduction. The speakers and crossover networks were optimized to provide the best sound obtainable not only from today's finest car stereo equipment ... but also from tomorrow's bi-amplified electronics.

The principle. Acoustically, the interior of a car is nothing like a living room. So for optimum sound reproduction in a car all sound should not emanate from the same location.

Two 2" Cone Tweeters True hi-fi componentry.

These sensitive tweeters offer wide dispersion.

Position them high in the front doors to get the full benefit of all the clean, crisp highs.

The woofer needs the large volume of the trunk to provide solid, deep bass. While the mid range and tweeter should be located in the front area to deliver all of their very directional frequencies.

Bi-amplification. The Jensen Separates offer this advanced capability. That is, sending the low and high frequencies to separate amplifiers for each channel.

One amp drives the woofer, another the tweeter and midrange.

The result is more "punch" and lower distortion.

Introducing our two-barrel, four-cylinder, twelve-valve, smooth-running, low-emissions wonder.

If you're really into cars and driving, you should know more about our amazing new MCA-Jet System with Silent Shaft. We think it's one of the most significant engine developments to come down the pike since the first American high-compression V8.

First off, it offers all the advantages of a four-cylinder engine... but without the vibration usually associated with the proverbial "four-banger." Its unique Silent Shaft design (available only with the five-speed manual and automatic trans missions) is the reason. Two counterbalancing shafts rotate in opposite directions to cancel out the noticeable power pulses inherent in normal four-cylinder designs.

Now comes the MCA-Jet A cutaway of our a Induction and compression phase.

Amazing little engine, part of our system. MCA stands for Mitsubishi Clean Air. The MCA-Jet System meets...even exceeds...the stringent emissions requirements now in effect in both Japan and America. Without loss in performance, too. A revolutionary new cylinder-head design that incorporates a third, or "jet," valve does the job. This valve introduces an extra swirl of air into the combustion chamber which swirls the fuel-air mixture and promotes a faster, more even, thorough burning of the mixture at ignition.

The MCA-Jet System. It's a simple, yet highly sophisticated, answer to a very complex problem. The kind of answer you would expect from people who care about cars and driving as much combustion phase. as you do.

Koss


Our theory sounds fantastic.

In an industry where trial and error methods are common, the Koss Theory of loudspeaker design may seem out of place. But once you hear the unmatched Sound of Koss in the new CM 1020 loudspeaker, you'll know our computerized theory helped make the optimum 3 bandpass speaker a reality.

The Koss Theory eliminates the guesswork in speaker design by selecting parameters for the best possible performance. That's why every part of the CM 1020 works superbly both alone and as part of the whole.

The dual ports, for example, enhance the woofer's front sound waves and dampen excessive woofer movement. There are two ports instead of one because two allow for improved cabinet tuning and greater structural stability. This added stability keeps the cabinet walls from beginning to flex causing unwanted sound waves.

The port-augmented 10-inch woofer is a special design that provides a 3 dB gain in electrical efficiency and a 3 dB down point of 31 Hz while offering maximally flat response over the low bandpass. To capture all the presence and musical energy from 300 Hz to 3.5 kHz, the CM 1020 features a performance synthesized-inch midrange driver. Handling the high bandpass is a 1-inch dome tweeter linked to a unique acoustic transformer. This Koss tweeter produces the highest energy output and lowest distortion of any 1-inch direct radiator tweeter on the market. Finally, to unite all these outstanding elements, Koss developed a unique, seamless crossover network.

Though we've tried to describe the superiority of the Koss CM 1020, nothing can match the thrill of a live performance. Ask your Audio Dealer for a demonstration, or write to Fred Forbes c/o the Koss Corporation for a free brochure of Koss CM loudspeakers.

After experiencing the CM 1020, you'll agree: hearing is believing.

Dual



Yes, the new Dual 604 is direct, drive.

Now let's talk about something really important.

You may have noticed that most turntable stories begin and end with the drive system. The tonearm is more or less an afterthought.

But not with Dual. Because the tonearm can make a big difference in how records sound and how long they last. Which is why Dual is very serious about tonearm design and performance. And why we can be very serious about tonearms in our advertising.

Let's consider the 604 tonearm.

The straight-line tubular design provides maximum rigidity with minimum mass. The four-point gimbal centers and pivots the tonearm precisely where the vertical and horizontal axes intersect. And the counter balance houses two specially-tuned anti-resonance filters that absorb parasitic resonances originating in the tonearm/cartridge system and chassis.

Operation s semi-automatic, with another unique Dual difference: the mechanical sensor. Switch it in and you feel when the stylus is positioned precisely over the 12" and 7" lead-in grooves. At the end of play, the tonearm lifts and returns to its post, and the motor shuts off, Automatically.

Now let's talk about the drive system. It employs a newly developed DC electronic motor with a highly sensitive CMOS regulator circuit and integral frequency generator. Platter speed is checked against rated speed 120 times per revolution. Wow and flutter are less than 0.03 percent, rumble is better than 70 dB. Well beyond the limits of audibility.

But the important story with any turntable is simply this. The drive system merely turns the record. It's the tonearm that plays it.

Dual 604, semi-automatic. less than $260. Dual 62t. fully automatic plus continuous repeat, less than $300 Both with base and cover. Actual re-sale prices are determined individually and at the sole discretion of authorized Dual dealers.

The Pulsating Hemisphere

A pulsating sphere represents one ideal of loudspeaker design. Such a speaker could be made any size desired and would still have completely omnidirectional output at all frequencies. For use close to a room wall, a pulsating hemi sphere would be equivalent.

But in practice it has always been necessary to compromise between dispersion and output capability. Making a normal tweeter smaller increases its high-frequency dispersion, but reduces the amount of acoustic power it can radiate. With all traditional horn, cone, and piston-type tweeters (including domes) it is not possible to achieve really satisfactory performance in both respects simultaneously. Flat-panel radiators are especially poor in high-frequency dispersion. And those of cylindrical shape, while having excellent horizontal dispersion, do not do well vertically.

There is now an elegant way to avoid this "either/or" dilemma. The Convex Diaphragm tweeter (used in all Allison loudspeaker systems) has as much cone area as a piston 11/16 inches in diameter, and can radiate as much acoustic power. But it does not operate as a piston. Generally convex in shape, the side of the cone curves inwardly to the voice-coil diameter, and the outside edge is fastened securely to the mounting plate. Because there is no compliant suspension the entire cone surface is forced to flex (changing its radius of curvature) as the voice coil moves axially. Every point on the cone moves diagonally, with an in-phase component of motion perpendicular to the voice-coil direction as well as a component parallel with it.

The tweeter thus simulates the motion of a pulsating hemisphere to a remark able degree.

Complete technical specifications for all Allison loudspeaker systems, and a statement of Full Warranty for Five Years, are available in our new catalog (free on request).

Radio Shack


Maxell? TDK? Scotch? BASF? Memorex? Ampex? Sony?

Suddenly there's a new name that eliminates the confusion (and ad-fusion):

"I'm Peter Nero. I kid you not.

Supertape Gold is everything they say it is even though the guy who wrote the ad is a personal friend." Could a Radio Shack own-make cassette tape be the greatest new formula in ferric-oxide 5-step-calendering audio tape? And isn't it neat that Supertape Gold requires no special bias settings? Well, we've built the tape, we've compared it in our labs with the summa cum hi-fi brands named above. And now it's your turn to see if your ears and your tape head confirm our findings. Fortunately, the price for your experiment is trifling.

If we're right, and Supertape Gold is indeed a breakthrough, then we both win. You get cleaner sound. And Radio Shack gets to be your cassette tape company--all 6,444 of our American and Canadian stores and dealers.

This a consummation devoutly to be wished!

It's true. Quanta turntables by BSR are good looking. But many people think our specs are even better than our bodies.

For instance, consider the 500. It's a single-play turntable with an exclusive feature. "The Final Touch." What is it? Well, at the end of a record!, the power shuts off. Then, magically and silently, the arm rises from the record and returns to its rest position. Automatically.

The 50C is made with DC Servo-Controlled Motor, which is the quietest motor made. It's belt driven. And it's got electronic speed control to assure you constant record speed. Wow ant flutter are less than .06% (WRNS). Rumble is better than-65 dB (Din B).

If you like those specs but prefer a multiple play turntable, then think about Quanta's 550-S.

Of course, both the 500 and the 550-S have a few things in common with our other Quanta turntables. Great value as well as great beauty. So come take a look at the entire Quanta line at your nearest Quanta dealer.' We give you a lot to choose from because we want you to like us for more than our good looks.

It's Marantz

Now, professional 3-head monitoring in a cassette deck.

Up to now you had to choose between a cassette deck for convenience. Or, reel-to-reel for professional recording features. Now have it both ways in the Marantz 5030 cassette deck.

Here's how:

The Marantz 5030 has separate record and playback heads ... the same as reel-to-reel. This gives you an instant check of the quality of your recording as you record. And, like some of the most expensive reel-to-reel decks, the record and playback heads on the Model 5030 are super-hard permalloy-a long-lasting metal alloy that gives better frequency response and signal to noise ratio than Ferrite material.

For precise azimuth alignment, both the playback/monitoring and record heads are set side-by-side within a single metal enclosure.

They can't go out of tracking alignment.

Complementing this outstanding "head-technology" is Full-Process Dolby Noise Reduction Circuitry. It not only functions during record and playback... but during monitoring as well.

What drives the tape past the heads is every bit as important as the heads themselves. For this reason the Model 5030 has a DC-Servo Motor System. The steadiest, most accurate tape-transport method. Speed accuracy is superb, with Wow and Flutter below 0.05% (WRMS).

To adapt the Model 5030 to any of the three most popular tape formulations, press one of the three buttons marked "Tape EQ and BIAS” There are settings for standard Ferric-Oxide, Chromium Dioxide (CrO2) or Ferri-Chrome (FeCr) tape.

With Mic/Line Mixing, two 'sources can be recorded at the same time, combining line and microphone inputs. The Master Gain Control lets you increase or decrease the overall volume of the total mix.

What else could we pack into a front load cassette deck? More features. Like a 3-digit tape counter with memory function. Viscous Damped Vertical-load Cassette Door. Switchable Peak Limiter. Fast-response LED Peak Indicators.

3" Extended-range Professional VU Meters.

Locking Pause Control for momentary shut-off in record or play... and Total Shut-off in all modes when the tape ends.

And, of course, the unbeatable Marantz 5030 is front loading. Easy to stack or fit on a shelf.

The styling is clean and bold. The sound is the truest recreation of what was put on tape. Your Marantz dealer has Model 5030 as well as the full line of Marantz cassette decks.

If you want the best-then do what you really want to do go for it.

Go for Marantz.
