Turn on the Fisher.
You'll get a 3-head Dolby deck that leaves you some money for tape.
There's no way-to know exactly what you're recording unless your tape deck has a third head for monitoring. But three-head cassette decks have always cost a lot of money.
Not any more Now there's the Fisher CR-5010. Its suggested retail price is just $229.95, and it has every thing you need.
The monitor head lets you listen to sound immediately after it's recorded. So you can be sure that your connections are secure, your mikes are in the right place, and your levels are OK. Dolby noise reduction cuts down the hiss and greatly improves the signal-to-noise ratio. Switchable equalization makes the most of the new tapes. And there's automatic shut-off and a precision pause control to make it all convenient.
You can spend a lot more for a 3-head Dolby deck. But if you want the most music for your money, turn on the Fisher CR-E010.

BOSE ON QUALITY
The 1801 Power Amplifier.
Much of the quality that distinguishes a truly outstanding electronic instrument from the average product goes unseen. It lies it the concern and skill of the design engineer, conservative rating of components, and extreme care in manufacturing.
For example, power transistors are costly. Yet using a large number assures that each works within its safe-area rating under any load and signal conditions. The 1801 uses 2b such power transistors.
A large power transformer is costly and heavy. In the 1801 the transformer is very large to provide tight regulation of supply voltages, providing very large power output with minimum stress on the output transistors.
Large amplifiers undergo unusual stresses during turn-on. The 1801 has a relay operated start-up circuit that limits currents and voltages in the power supply circuits during turn-on.
Yet what is on the surface perfectly complements the underlying quality of construction and design. 1300 square inches of heat sink. Two oversize VU meters.
A two-position in 3ut selector. Individual gain controls for each channel. A three-position speaker selector. And a light emitting diode display of power output.
The size, power and features of the 1801 are not for everyone. But for the nearest approach to the ultimate... in quality of design, construction, and performance ... there is no other amplifier.

Crown POWER reveals a new level of listening.
Discover the five elements of Crown power that make hearing the DC300A such a unique listening experience.
Extreme low distortion:
Maximum total harmonic and intermodulation distortion of 0.05% over a bandwidth of 1-20,000 Hz. Such minute levels made it necessary for Crown to design its own intermodulation distortion analyzer, now in use industry wide.
Continuous power:
155 watts/channel minimum RMS into 8 ohms stereo, 310 watts minimum RMS into 16 ohms mono, over a bandwidth of 1-20,000 Hz.
Complete protection: The DC300A is fully protected against shorted loads, mismatched connections, overheating and excessive line voltage, input overload as well as RF burnout. And this amp will drive any type load, resistive or reactive.
Uncommon reliability: The DC300A's big name rock groups demand DC300A's be cause of their rugged ability to withstand tour-long punishment and still produce flawless sound.
And major recording studios insist on Crown to keep time losses at a minimum. The professionals know from experience Crown's unqualified dependability.
Exclusive warranty: Crown's unique warranty covers not only parts and labor but round-trip shipping for three years. These shipping costs are an important factor in our warranty, and it is not surprising that no other amplifier manufacturer offers this service.

Many receivers may give you all this.
But they cost a lot more.
Technics SA-5150 Power and Price
At $229.95, the SA-5150-one of four new Technics stereo receivers-gives you more power and less THD than the five best selling brands do at a comparable price (16 watts per channel, minimum RMS, into 8f/from 40Hz to 20kHz, with no more than 0.8% total harmonic distortion).
Large Capacitors in Power Supply
You'll hear all the lows of the bass guitar and all the highs in the crashing of cymbals the way many receivers won't let you hear them-without distortion. Because the SA-5150 uses 4700,uf electrolytic capacitors in the balanced positive and negative power supplies. So you get the reserve power you need when you need it most.
Direct Coupling
For a tighter, cleaner, more rounded bass. Because the SA-5150's amplifier output is directly coupled to the speaker terminals with no capacitors in between. So you get more power output as well as a higher damping factor in the low frequency range. And the SA-5150 is one of the few receivers in its price range with direct coupling.
Phased Lock Loop IC in FM PLL improves stereo separation by maintaining precise phasing in FM. And to help keep distortion down to a point where you won't hear it (0.4%), the SA-5150 uses flat group delay ceramic filters in the IF section. There's also a sophisticated front end that delivers a selectivity of 70d3, 1.907 sensitivity and a capture ratio of 1.8dB.
So if you want a receiver with large capacitors in the power supply. Direct coupling. Phase Lock Loop in FM. And 16 watts RMS at $229.95.
There's only one receiver you want. The SA-5150.
The concept is simple. The execution is precise.
The performance is outstanding. The name is Technics.

Sony V-FETs
While everyone is still trying to make V-FETS at any price, we now make them at a lower price.
When Sony introduced the first amplifiers with vertical field-effect transistors last year, the reactions were nothing short of incredible.
Consumers wrote in asking where they could hear the equipment. Audiophiles demanded to know where they could buy it. And our competitors wanted to know how they could make it.
In fact, the only problem was that more people couldn't afford the $1300 price.
So, we at Sony decided to do something about it.
And what we've come up with is our new $400 V-FET integrated amplifier, the TA-4650. The TA-4650 is quite an advanced little piece of equipment. Because the V-FET isn't just another combination of gadgets, or a souped-up version of the same old thing. It's a completely new device that combines the good points of both bi-polar transistors and triode vacuum tubes.
Without suffering the drawbacks of either. Because it's made with V-FETS, the TA-4650 gives you a new level of highly defined triode sound; along with the efficiency and stability found only in solid state devices.
The TA-4650 delivers 30 watts per channel, minimum RMS at 8 ohms, 20Hz-20kHZ with no more than 0.1% total harmonic distortion.
It has a direct coupled power amplifier stage. As well as direct coupled FET amplifiers in the tone control and buffer stages.
Its bass and treble controls have a turnover frequency selector that starts at 250HZ/500HZ for bass and 2.5kHZ/5kHZ for treble.
Its volume control is equipped with a switch for 20dB muting. And it has a level control memory device so volume can be set at any predetermined point.
But as good as our new V-FET amplifier is, we're just as proud of the components we make to go along with it.
Our ST-4950 AM/FM stereo tuner, for example, has a MOS FET front end, uni-phase solid state filters and IC's in IF stages. This allows an FM capture ratio of only 1.0dB, selectivity of 80dB and an S/N ratio of 70dB. The ST-4950 also has a phase-locked loop (PLL) MPX section. Which means you get excellent stereo separation and low distortion.
Of course, if you're going around looking for a turntable, by all means take a look at our PS-4750 (cartridge sold separately).
It has a direct drive servo motor with a wow and flutter rating of only 0.03%.
Its base and platter are made from molded compound instead of metal, so resonance has been greatly reduced. It also has air-damped cushions, which compensate for warpness in records (again reducing resonance). The end result is a much cleaner sound.
It's no accident that Sony makes the world's first commercially available V-FET equipment. Or that we have matching components good enough to complete your system.
You see, we've got more solid state audio experience than anyone else. We've been at it for twenty years. For proof just stop by your Sony dealer.
And use your ears.
TA-8650, 80 watts per channel, min. RMS 8 ohms. 20Hz-20kHz, with no more than 0.1% total harmonic distortion.

Dolby FM is happening
Remember the first time you came across Dolbyized cassettes? And how surprised you were that music could sound so good in such a convenient form? Well, now the same principles are being used to improve FM broadcasting. The audible effect of the Dolby system as used in FM is a bit more subtle than with cassettes. But the overall results are just as important. Dolby FM is cleaner, with sparkling high frequencies free of limiting.
And, of course, noise is reduced, which often increases the area of good reception.
As of August 1975, over 100 US stations have purchased the Dolby Model 324 or 334 FM Broadcast Encoder. (The encoder accurately compresses the signal in accordance with the Dolby B-Type characteristics and changes the effective transmission time-constant to 25 microseconds. At the same time, the station eliminates any high frequency limiting required previously).
As you can hear for yourself, a Dolby FM signal is compatible. In fact, most people find it a better signal even when received on their normal equipment without Dolby decoding.
However, you may be the kind of person who likes to take advantage of every opportunity for improvement. If you use Dolby circuitry during reception, you can bring the signal even closer to the quality of the original source material.
Naturally, the noise is reduced. But that's not all. Dolby compression is standardized, recoverable compression.
By using Dolby encoding instead of the conventional high frequency limiting normally required during transmission, the station gives the listener at home the opportunity of recovering the full frequency range and dynamics of the signal.
If these prospects excite you, we think you will soon be wanting to check out the new generation of receivers with built-in Dolby circuitry.* Some Dolby licensees are already producing their new models, and others have new designs in the pipeline.

AKG
A lot of headphones hurt. After a few minutes they begin to weigh you down. A few minutes longer, and they start building a tiring pressure on your ears. They hurt too much to keep on your head.
Or you can slip on the new lightweight AKG K-140 headphones. They automatically adjust to the contour of your head. (With our exclusive Cardair swivel and supra-aural design, the 140 doesn't have to make a squeeze fit.) So there's no ear pressure. And no thumping head. You can listen for hours. Painlessly.
The 140 also lets you enjoy music at high sound levels without punishing your ears.
Yet, you can hear your environment because the 140 won't isolate you. After all, music isn't played in a vacuum. But don't worry, no one will be disturbed when you wear a 140.
We designed the 140 for professional monitoring. Which means wide bandwidths and low distortion, and sound pressure levels over 115 dB. The 140 is compatible with all outputs, 4-600 ohms. Weight: a scant 6.2 ounces. Price? That's so scant it won't give you a headache either. $34.50.

Yamaha
THE END OF THE DOUBLE STANDARD.
OUR LEAST EXPENSIVE RECEIVER LOW DISTORTION AS OUR MOST HAS THE SAME EXPENSIVE RECEIVER
At Yamaha, we make all our stereo receivers to a single standard of excellence.
A consistently low intermodulation distortion of just 0.1%! A figure you might expect only from separate components. Maybe even from our $850 receiver, the CR-1000.
But a figure you'll surely be surprised to find in our $330 receiver, the CR-400.
So what's the catch? There is no catch. Simply a different philosophy. Where high quality is spelled low distortion.
You'll find Yamaha's single mindedness particularly gratifying when compared to the amount of distortion other manufacturers will tolerate throughout their product lines.
(See chart.) Particularly gratifying and easily explained.
Less of what irritates you most.
While other manufacturers are mostly concerned with more and more power, Yamaha's engineers have concentrated IM Distortion Comparison YAMAHA Brand "A" Brand "B" Brand "C"
CR-1000 .1% .1% .15% .3%
CR-800 .1% .3% .3% .5%
CR-600 .1% .5% .5% .8%
CR-400 .1% 1.0% .9% 1.0%
With most manufacturers, price determines quality. However, in the above chart, you can see how Yamaha alone offers the same quality (low distortion) throughout our entire line, regardless of price, on less and less distortion.
Particularly intermodulation (IM) distortion, the most irritating to your ears. By virtually eliminating IM's brittle dissonance, we've given back to music what it's been missing.
A clear natural richness and brilliant tonality alone cannot describe. A new purity in sound reproduction.
A musical heritage.
Our seeming preoccupation with low distortion, in general, and the resulting low IM distortion, in particular, stems from Yamaha's own unique musical heritage.
Since 1887, Yamaha has been making some of the finest musical instruments in the world.
Pianos, organs, guitars, wood winds, and brass.
You might say we're music people first.
With our musical instruments, we've defined the standard in the production of fine sound. And now, with our entire line of receivers and other stereo components, we've defined the standard of its reproduction.
Four different receivers, built to one standard.
Between our $330 CR-400 and our $850 CR-1000, we have two other models.
The $460 CR-600 and the $580 CR-800.
Since all are built with the same high quality and the same low distortion, you're probably asking what's the difference.
The difference is, with Yamaha, you only pay for the power and features that you need.
Unless you have the largest, most inefficient speakers, plus a second pair of the same playing simultaneously in the next room, you probably won't need the abundant power of our top-of-the-line receivers.
Unless you're a true audiophile, some of the features on our top-of-the-line receivers might seem a bit like gilding the lily. Selectable turnover tone controls, variable FM muting, two-position filters, even a special five-position tape monitor selector.
However, you don't have to pick one of Yamaha's most ex pensive receivers to get a full complement of functional features as well as our own exclusive Auto Touch tuning and ten-position variable loudness control.
The End of the Double Standard.
Just keep in mind that all Yamaha stereo receivers, from the most expensive to the least expensive, have the same high quality, the same low distortion, the same superlative tonality.
It's a demonstration of product integrity that no other manufacturer can make. And, an audio experience your local Yamaha dealer will be glad to introduce you to.

ADS
Invisible Sound, Compact and Powerful.
The ADS L710 and L810 are four driver, three way speakers for audiophiles who demand studio performance from a system that is still compact enough for bookshelf placement. These systems share exceptionally wide-range frequency and power response that places them in the small select group of reference quality speakers without demanding the usual penalty of size and price.
We invite you to test them against any high quality speakers regardless of cost.
Lister, how accurately the virtually massless 1" soft-dome tweeter follows every detail of a solo violin.
Notice how uniformly the unique mid-range driver reproduces the subtleties or a familiar voice-no brassy sound ever; instead, un-muffled openness. The 2" soft dome smoothly radiates nine times as much power into a hemisphere ADS 110 as a conventional speaker of the same area.
Then train your ears on the woofers. They are small in diameter for optimum transient and power response; this extends clarity and detail down into bass. It is elegantly accomplished by two active, perfectly phased drivers with unprecedented lateral excursion. You never before heard a bass drum come so much alive.
Flawless consistency in all these qualities is our uncompromising standard of excellence, and it is built into every model from ADS.
Your local ADS dealer will proudly demonstrate the L710 and L810 in his sound studio. Take the time and test them critically. Take the step beyond transparency. Experience "Invisible Sound." It then will be Impossible for you to accept anything less.
