Only one direct-drive semi-automatic has a concrete advantage.
If you want the precision speed control of direct drive and the convenience of a turntable that shuts itself off, you can choose from many brands.
But only the Kenwood KD-3070 has a solid advantage that can really make a difference.
Because the turntable base is made with dense resin concrete, it virtually eliminates acoustic feedback.
That means that no matter how loud you play your music, the vibration in the air won't couple vibrations to the tonearm and cause howl.
In fact, while we don't recommend it, you can actually place this turntable on top of a speaker and crank up your volume without causing feedback.
The same thought that goes into creating our resin concrete base goes into the design of our tonearm and turntable controls as well..
Dense resin concrete in base virtually eliminates vibration And if that's not enough to convince you, consider this: You can buy the KD-3070 for less than $175.00.* That's a concrete advantage, too.
*Nationally advertised value. Actual prices are established by Kenwood dealers.

Mitsubishi Pre-empts the Receiver.
Introducing the docking tuner/preamplifier and amplifier. Exclusively Mitsubishi.
It is not a receiver. It is what receivers try to be.
It is two components. Tuner and preamplifier on one chassis.
That docks with our dual monaural power amplifier.
It has The DM Factor.
Dual Monaural construction.
Exclusively Mitsubishi.
It means more than mere stereo. It means inside our stereo tuner/preamplifier are two perfectly matched mono preamplifiers. Just like our component preamplifiers. But not like any receiver.
Because it is not a receiver.
It is a tuner with THD in stereo at 0.08%.With signal to noise in stereo at 75dB.
With switchable selectivity for uncompromising reception.
With incredible clarity and definition. Ten violins sound like ten violins, not one big mushy solo.
It is a dual monaural pre amplifier with interchannel separation at better than 80 dB at 20kHz. Far better than any receiver. With THD at less than 0.002%. For effective elimination of leaks, crosstalk, or any influence able to distort the stereo image.
With the ability to handle the moving coil cartridge.
For signal to noise at-77dB (0.1mV input). Previously un heard of in any preamplifier.
It is a tuner/preamplifier that docks with a dual monaural power amplifier. 100 watts or 150 watts. With max RMS output power into 8 ohms from 15Hz to 30kHz.
With THD at no more than 0.05% at rated output.
It is a single, uncluttered unit with the convenience of a receiver. But the integrity of the exclusive DM Factor. The prime factor in making sure our equipment doesn't fictionalize any music that it plays.
Because the equipment is Mitsubishi. And Mitsubishi has a standard: what comes out must be as real as every thing that went in.
Listen to the most expensive receiver you can. then hear our DA-C20 dual monaural tuner/preamplifier and self-docking amplifier.
Hear what our standard really sounds like.
And, believe us, it doesn't sound like any receiver in the world.

Enter the New Professional Calibration Standard, Stanton's 8815 Mike Reese of the famous Mastering Lab in Los Angeles says: "While maintaining the Calibration Standard, the 881S sets new levels for tracking and high frequency response. It's an audible improvement. We use the 8815 exclusively for calibration and evaluation in our operation". The recording engineer can only produce a product as good as his ability to analyze it. Such analysis is best accomplished through the use of a playback pick-up. Hence, better records are the result of better playback pick-up. Naturally, a calibrated pick-up is essential.
There is an additional dimension to Stanton's new Professional Calibration Standard cartridges. They are designed for maximum record protection. This requires a brand new tip shape, the Stereohedron, which was developed for not only better sound characteristics but also the gentlest possible treatment of the record groove. This cartridge possesses a revolutionary new magnet made of an exotic rare earth com pound which, because of its enormous power, is far smaller than ordinary magnets.
Stanton guarantees each 881S to meet the specifications within exacting limits. The most meaningful warranty possible, individual calibration test results, come packed with each unit.
Whether your usage involves recording, broad casting or home entertainment, your choice should be the choice of the professionals ...the STANTON 881S. Stanton.

Nikko Sounds as Professional as if Looks
5-gang capacitor
If you thought Nikko only makes rock-solid, quality-built receivers, we have some pleasant surprises.
For the discerning listener, we pre sent a selection of rack-mountable stereo components from Nikko Audio's Professional Series. The Gamma 1 FM tuner, The Beta 1 preamp and the Alpha II amplifier.
One look at the front panel controls and it is obvious these units possess an unusual combination of creative features. Nikko engineers also developed the advanced technology you can't see. Technology which makes these components truly professional in sound as well as appearance.
------ Toroidal power transformer
The advanced design 5-gang capacitor (highest rated capacitor available) gives the Gamma I tuner superior FM sensitivity (1.8 µV) and selectivity (35dB wide, 85dB narrow). You get the signal you want, and only the signal you want to hear.
The thin-line Beta I preamp employs high voltage FET's for exceptionally fast signal reaction and extremely high efficiency and linearity in the high frequency range. A toroidally wound power transformer reduces hum radiation while the phono overload rejection capability is one of the highest ever measured.
On the Alpha II amplifier, totally independent, dual power supplies offer far greater dynamic range and lessened crosstalk than the usual split single power supply and significant headroom. (120 watts per channel, both channels driven into 8 ohms, from 15 Hz to 20 kHz with THD and IM distortion a phenomenally low 0.03%. ) These ore bur a few examples why Nikko sounds as professional as it looks. Nikko designs and builds all its stereo equipment with dedication to total reliability, highest quality and superb performance. And the price is always affordable.

We admit that the Sansui G-9000 is not the world's only great DC receiver......there are four more great DC receivers. The Sansui super fidelity DC G-line.
The Sansui G-9000 is, without t, a great receiver--perhaps the most advanced receiver available to day 'Never Peters has music reproduction been so clean, brilliant and true.
Just listen to a pure power G-9000. You writ actually hear its distinctly superior performance. Now leak at the specifications and you'll Understood why The amplifier section (patent pending) is genuine DC r its frequency response extends all the way from 0Hz DC) to 200khz (from main-in,--3db) it is also Direct Coupled (which means no capacitors in the signal path or negative feedback loop) for fastest response to all musical signals. The slew rate is extraordinarily high, 80V/usec- with a rise time of 1.4p u-sec.
Our sophisticated amplifier design virtually eliminates distortion. Total harmonic distortion is all the way down to 0.02% at full rated power, MO watts per channel, min. PNIS, both channels driven into 8 ohms from 20-20,000Hz.
Such outstanding specifications ensure superb music reproduction. And we at Sansui believe that your audio components must also provide great creative versatility and be a pleasure to operate. So through long months of re search and testing, we've developed a receiver that is truly human engineered. The full complement of controls are beautifully positioned and outstand tricky accurate. Just touch them and fall in love with the special "Sansui feel." Why then, with, the unmatched specifications, incomparable design, and the amazingly reasonable suggested retail price ($1,050) of the G-9903, don't we at Sansui claim exclusive superiority for the G-901X]?
Because …
There are four more Sansui pure power G-line DC receivers. All of them feature the same sophisticated Sansui G, 9000 DC amplifier circuitry (patent pending) that produces specifications which essentially define the present state-at-The-art in audio engineering.
And with these outstanding specifications the quality of music reproduction has reached a new high. When you listen to any Sansui super fidelity receiver, we're convinced that you will whole-heartedly agree.
While we won't reveal all of our design secrets (after all, many other manufacturers are already trying to imitate our DC technology), we would like you to know some of the reasons why with Sansui’s G-receivers, your Gusto Can sound more true-to-life lilac ever it has before.
DC Response: A Matter of Time
Any amplifier whose frequency response does not go down to DC uses a 'reactive" device- usually a capacitor- somewhere in its design. Every reactive device introduces a certain amount of frequency-dependent time delay (or phase shift) in the signal path, so the output signal Is phase distorted and no longer looks exactly like the input signal DC design, which does hot :ISO Capacitors, completely eliminates this ambler-,
Negative Feedback & Dynamic Response
The conventional approach to the problem of distortion Is who' engineers call negative feedback. Too much negative feedback, however, can actually increase the dynamic distortion, This particular distortion is frequently called “transient intermodulation distortion"(TIM).
Because of the advanced design, the pure power DC amps in the Sansui’s G-series receivers need less negative feedback to reduce distortion to the vanishing point so they do not exhibit the slow dynamic response that causes TIM. As you can see from the specs. the Sansui G-series receivers reproduce signals over an extremely wide frequency mice with almost immeasurable distortion
Slew Rate and Rise Time
Because the quality of Sansui's DC receivers is so much better than has ever been available in any receiver, conventional measurement techniques are insufficient for describing their performance. Electronics engineers are therefore using new measurement techniques that you will soon hear a lot about.
The most important new measurement is slew rate, which defines the maximum rate of change of the output voltage from an amplifier. The required rate of voltage charge is greater for high frequencies-How we on amplifier can handle the high-frequencies at high power Is an Index of how well it can reproduce musical transients Slew rate measurements, which show the maximum voltage change the amplifier can deliver Is one microsecond (millionth of a second) thus indicate an amplifier's transient capabilities. Naturally, toe more powerful the amplifier, the greater the require a output, so the greater must be tin slew rate specifications. Rise time defines how long It takes an amp tier to go from 10% to 90% of rated output. Naturally, the less time required, the better.
To achieve high slew rate and fast rise time, an amplifier's frequency response must extend far beyond the conventional 20,000H, whit& is why these Sansui G-series amplifier sections all have a frequency response that extends to 200,000Hz! Compare our measured slew rates, model for model, against those of other receivers and you'll know why you can hear the musical difference Sansui engineering makes.
Phone Performance
Phono signal-to-noise ratio (from BOOB in the G-9000 to 7805 In the G-5000) and RIAA accuracy (± 0.2dB. 20-20,000. except for the G-5000) of the Sansui G-receivers are truly remarkable. Maximum phono input capability of the G-900010 more than 330mV, achieved by use of a FET differential input circuit. This input-
capacitor-less (ICU) design, used in all the G-receivers, e extremely stable and virtually free from distortion.
The tuner (or FM) Section
The design of the FM section of the Sansui G-receivers is similar to that of our highly acclaimed separate tuners. In addition to the high sensitivity (8.7dBf [1.5µV] for the G-9000) and high selectivity (90dB for the G-9000) the FM sections of the G-series moor potato ceramic IF filters to achieve exceptionally low FM stereo distortion (0.08% for the G-9000)- Our top off-the line also offers user-selectable IF bandswitch for highest selectivity or lowest distortion.
Independent Power Supplies
For the cleanest possible reproduction, Sansui engineers designed the G-line with fully independent power supplies for each channel in order to prevent a surge of power in one channel from 'robbing' power from the opposite channel. lb minimize hum and noise We have used a dual-wound toroidal transformer (in the three most powerful models). The large, low-inductance oval capacitors in the G-9000 and the advanced design, low Impedance electrolytic capacitors in the other G-models provide more-than-ample power reservoirs.
At in all, we at Sansui are convinced that if you really love music you will surely choose one of our pure power DC G-receivers. There are no other receivers available today that can offer you all these advantages: superior musical performance, sophisticated DC design, a full complement of controls and outstandingly beautiful styling.

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 is 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 direct-drive system. It employs a newly developed DC electronic motor, with speed regulated by a CMOS integrated circuit and digital reference circuit. Speed accuracy is within 0.001 percent. Wow and flutter are less than 0.03 percent, rumble better than 70 dB. As with any great drive system, that's far beyond 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.

When it comes to speaker design, JVC goes 2969 times further.
Traditionally, speakers are designed and tested by placing a special microphone in front of the speaker, and examining the sound it picks up on an oscilloscope. The oscilloscope pattern is then drawn or photo graphed for comparison purposes. And, by a tedious trial-and-error process, speaker design engineers try different speaker, crossover and enclosure combinations to express their sound philosophy.
But JVC has put an end to these archaic and time-consuming procedures.
By using a specially-constructed electro-mechanical transport device that creates a field of 2969 microphone positions; then feeding these sound impulses into a computer, then onto a laboratory video screen and onto motion picture film, JVC engineers can actually see what a speaker will sound like... before they get too far down the line in the design process.
This exclusive JVC development is called Phase Moire ("Moray") Propagation Pattern Technology.
How the Phase Moire technology works: The motion picture film produced by the combination of nearly 3000 pickup points, the computer, and high-speed filming of the resulting patterns from the face of the video screen, actually shows how a speaker, crossover network or entire speaker system performs, rather like "sound in action." It all looks good, but it sounds even better The SK-1000 is the careful result of Phase Moire Technology and human engineering.
Capable of handling up to 170-watt peaks (85 watts RMS), this extraordinary-sounding, unusually efficient speaker system delivers truly magnificent, rock-solid bass from its 12-inch free-edge woofer and heavy magnet structure. Vocals and midrange are unusually smooth, with a pleasing sense of presence, thanks to our specially-designed 5-inch midrange driver. Clear, crisp brilliant highs are produced with a 1-inch dome tweeter that disperses them evenly within the listening area.
A final note on technology: Once we discovered the technology needed to produce better-performing speaker components and systems, we put it to work to help us build a modestly-proportioned (and priced) speaker system that would come as close as possible to the highest levels of integrity in musical reproduction.
We feel we've succeeded. But all the technology in the world can't fool two of the most sophisticated testing devices known: your ears. And all the words in the world can't really tell you what the SK-1000 really sounds like. So we suggest that you hear what we've been talking about at a JVC dealer.
These two Phase Moire patterns represent the crossover frequency response of two similar multi-speaker systems. The left-hand pattern was produced by a JVC SK -1000. Its evenly -undulating shapes indicate a smooth transition from speaker element to another. The turbulant, uneven pattern on the right is typical of a poorly -designed speaker/crossover combination.
MID/TREBLE LEVEL CONTROLS-- Phase distortion and power loss are kept minimum.
1" DOME TWEETER-- Elastic hemispherical diaphragm permits wide-sound dispersion with low distortion.
5" CONE MIDRANGE--Hard surfaced cone and aluminum alloy metal cap for midrange lucidity and tightness.
12" WOOFER --Accepts unusually high power for real-life bass.

Precision guide rollers with stainless feel pins provide smoother tape movement with minimal friction.
In 1973, things were different.
When we invented Grand Master studio mastering tape, only professional recording engineers could appreciate it.
For its incredible output sensitivity. Its amazing saturation capacity. And its low distortion qualities.
Not even hard-core audiophiles had the kind of equipment that could drive tape hard enough to explore Grand Master's ultra-wide dynamic range.
Or begin using its dramatic improvement in signal-to-noise.
Or its low third-harmonic distortion.
So while Grand Master went on to become the unquestioned leader in the professional recording field, we had to wait for things to change before we could intro duce it to the home recordist.
And change they did.
Home equipment improved dramatically. Better quality components produced higher outputs. And lower distortion.
And now that you have really 'good" equipment, you can appreciate the tape the pros have been appreciating for years.
