NEW PRODUCTS--Roundup of the latest audio equipment and accessories (with vintage magazine ADs)
Nikko Adds New Preamp and Class A Power Amp
The Nikko Beta V preamplifier and Alpha V power amplifier are the latest additions to that company's amplifier line. The Beta V's very slim front panel has no tone controls, but features a variety of switchable cartridge-loading values. Phono-input impedance is selectable at 10,000, 33,000, 47,000, 68,000, and 100,000 ohms, while three load-capacitance settings are provided: 0, 47, and 150 picofarads. Phono-input level is adjustable. There is a five-position selector switch used in con junction with a three-position "channel selector." On Channel 1, phono-input impedance and capacitance are adjustable; on Channel 2 only the capacitance and on Channel 3 only the impedance is adjustable. The Beta V has a 16-Hz subsonic filter as well as a mode switch with positions for stereo, mono, and stereo reverse. The volume control is a step-type attenuator switch.
Key specifications for the Beta V area phono-input sensitivity of 2 millivolts (mV) and a 100-mV sensitivity for the tuner and auxiliary inputs. Total harmonic distortion is 0.01 percent. The signal-to-noise ratio of the phono section is 72 dB (A weighted); for the high level amplifier it is 100 dB. Rated output is 1 volt into 600 ohms. The Beta V, which utilizes Cannon-type three-conductor connectors in place of the standard phono plugs and jacks, measures about 2 x 19 x 17 inches. Price: $750.
The companion to the Beta V is the Alpha V power amplifier, a Class-A design rated at 100 watts per channel into 8 ohms. The front panel of the Alpha V has separate average-reading power meters for each channel, as well as an on-off switch and a speed control for the amplifier's cooling fan. It is fitted with chrome-plated rack handles. The Alpha V may be used as a d.c. amplifier (response is flat from 0 to 60,000 Hz) or with a high-pass filter inserted. Both total harmonic, and inter-modulation distortion are rated at 0.06 percent, and the signal-to-noise ratio is 110 dB (A weighting). Like the Beta V, the Alpha V uses three-conductor Cannon-type connectors. It measures about 9 x 19 x 17 inches and weighs about 60 pounds. Price: $3,000.

Revox Announces a New Open-reel Deck
The Revox B77 is the new semi-professional open-reel tape recorder from Studer Revox, joining Models A77 and A700 in the manufacturer's line. The B77 has a direct-drive servo-controlled capstan with 7 1/2- and 3-1/4-ips tape speeds and is available with a quarter- or half-track head assembly. The B77 has full electronic-logic pushbutton control of tape motion. It also includes a tape-cutting/ editing jig on its front panel. The input circuitry of the B77 can handle a large range of input voltages-it takes up to 24 dB (over 0 dB VU) before overloading-so that its overload limitations are really those of the tape. Bias-oscillator frequency is 150 kHz. The front panel has large recording-level meters with VU characteristics, as well as LED's to indicate overload. The microphone inputs take sources with impedances of 600 ohms or higher; the headphone outputs drive 600-ohm or greater impedances.
Rated frequency response of the B77 is 30 to 20,000 Hz +2,-3 dB at 7 1/2 ips, and 30 to 16,000 Hz +2,-3 dB at 33/4 ips. At 7 1/2 ips the signal-to-noise ratio is 66 dB in the half-track format (DIN A weighting). The record-playback total harmonic distortion is under 1 percent, and wow and flutter are below 0.1 percent. Maximum speed deviation is ±0.2 percent. There are special design features to enhance reliability in studio use-for example, it is possible to field-replace all components without soldering. The B77 is housed in a portable polypropylene case with a fold-out carrying handle, the dimensions of which are 16 1/4 x 18 x 8 inches. Weight is 38 pounds. A soft cover is available. Price: $1,195.
Bib Device for Disc-static Neutralization
Among several new products from Bib Hi-fi Accessories, Inc. is an anti-static gun, the Model 106 (shown). It is used to remove the static electrical charge from disc surfaces, and it is provided with a small electroscope for observing the degree of charge on the disc surface. Also included with the gun is a foam pad for wiping neutralized dust off the record surface.
Another Bib accessory, the Model 150, is a tape-care kit including accessories for cleaning tape heads and splicing cassette tapes.
The 150 has a head-cleaning tool with an adjustable probe that permits the user to clean the often hard-to-reach tape heads in cassette recorders. A small dentist's mirror is included for checking the status of the head, as are extra cleaning pads and 22 cubic centimeters of cleaning fluid. The cassette-tape splicer includes a jig for holding the cassette in position as well as a razor cutter and a supply of splicing tape.

Aiwa Turntable Will Activate Cassette Decks
Aiwa's new model AP-2200 is a direct
drive semi-automatic turntable with a unique switching feature that can automatically turn several of Aiwa's cassette decks on for re cording at the beginning of the record-playing cycle. The AP-2200 also has its operating controls mounted on the front of the turntable base so that it can be operated with the dust cover in place. It is a two-speed unit (33 1/3 and 45 rpm) with a pitch adjustment covering a range of ±3 percent. The high-density base is synthesized of a ceramic-resin material said to reduce vibration, and it is mounted on adjustable rubber feet.
The AP-2200 has 0.035 percent wow and flutter (wrms) and a rumble level of -70 dB. Approximate dimensions are 4 3/4 x 16 3/4 x 14 1/4 inches, and the unit weighs about 15 pounds. Price: approximately $200.
Heath Announces New AM/FM Receiver Kit
The AR-1429 is Heath's latest stereo receiver. It features an adapter for an external Dolby decoder for FM broadcasts (a plug-in decoding circuit, the AD-1504, is available from Heath) which can be connected to the AR-1429 internally. A switch on the front panel adjusts the tuner de-emphasis from 75 to 25 microseconds for use with the decoder.
There are preamp-out, power amp-in jacks on the rear panel so that signal-processing equipment can be put in the signal path. Signal-strength and channel-center meters are included on the front panel.
The AR-1429 is rated at 35 watts per channel continuous power into 8 ohms. Total harmonic distortion is under 0.1 percent for any frequency from 20 to 20,000 Hz, and inter-modulation distortion is less than 0.2 percent.
The signal-to-noise ratio at the phono input is 65 dB for a 2-millivolt input signal. Key FM specifications include a usable sensitivity of 1.8 microvolts (IN), equivalent to 10.3 dBf, and a 50-dB quieting sensitivity of 4µV (17 dBf) in mono and 40µV (37.3 dBf) in stereo.
Capture ratio is 1.8 dB, and alternate-channel selectivity is 80 dB. The FM channel separation is 40 dB at 1,000 Hz, 25 dB at 10,000 Hz.
FM distortion is under 0.35 percent in stereo for a 65-dBf input. Dimensions of the AR-1429 are 4 3/4 x 20 x 13 1/2 inches. Kit price (mail order): about $320.
Compander Kit from Phoenix Systems D Phoenix Systems is offering its model P518-S, a new audio compander for tape re cording in kit form. The unit is a full two-to-one compander, offering 2:1 compression on recording and 1:2 expansion on playback. It is not intended to be used as a simple expander for playback only. The P5 18-S has front-panel pushbutton switches for power and compander mode (record or playback) and a LED which lights whenever the input signal exceeds 0 dBm (1 milliwatt into 600 ohms). The compander circuitry works over the entire audible frequency range (it is not limited to treble only, as are some companders) and applies compression or expansion to all signals with levels other than 0 dBm. For example, in the compression mode, any signal exceeding 0 dBm in level is attenuated by a factor of two, and any signal with a level of less than 0 Him is boosted by a factor of two.
The P518-S has a maximum input/output level of 12 dBm, and the maximum output current is 20 milliamperes. Tracking error is ±0.2 dB. Total harmonic distortion in either the compression or expansion mode is a maximum of 0.3 percent; however, according to the manufacturer, since the same integrated circuit is used for both functions, most of the harmonic distortion introduced in the recording mode will be canceled on playback. Noise level is-96 dBm (IHF A weighting). The P518-S has approximate dimensions of 2 x 7 x 4 1/2 inches. Kit price: $59.
Two High-efficiency Speaker Systems From Kenwood
Two new dynamic speaker systems are available from Kenwood, the LS-407A and the LS-408A (shown). Each is a three-way, vented-box design with a 13/4-inch cone tweeter and a 4 3/8-inch mid-range; the LS-407A has a 10-inch woofer and the LS-408A a 12-inch woofer. The tweeter employed in both models has a one-piece cone-and-dust-cap construction. Continuously variable level controls ad just the output of the tweeter and mid-range within ±3 dB.
The key specifications for both speakers are very similar: frequency response is 48 to 20,000 Hz ±3 dB, nominal impedance is 8 ohms, and sensitivity is 93 dB sound-pres sure-level output for a I-watt input measured at a distance of 1 meter. For the LS-407A, in put power of 20 to 120 watts is recommended; 20 to 160 watts is the recommended amplifier range for the LS-408A. Dimensions are 25 3/4 x 15 x 12 1/2 inches for both speakers. Price of the LS-407A is $180; of the LS-408A, $250.

CAN YOU TELL THE EXPENSIVE IMITATIONS FROM THE AFFORDABLE ORIGINALS?
When Phase Linear introduced the first real high-power, high-fidelity amplifier in 1971, the philosophy of audio component design was abruptly changed.
Almost overnight, Phase Linear became synonymous with high-quality, high-technology, high-powered high-fidelity.
The entire audio industry was forced to take no ice Most H-F companies had not expected high power to become generally accepted as the optimum means of achieving sonic realism Suddenly, companies found themselves spending large amounts of money in R&D Engineering, and Marketing in a very short period of time.
Who dc you think picks up the tab? Contrary to what some manufacturers would like you to think, Hi-Fi companies are not philanthropic organizations. They can't absorb the cost. This rapid expenditure of money must be factored into the retail price of the component The result? You pay a higher price. You most certainly receive the performance as advertised by these expensive imitations. But you also pay a penalty Take a good look around the next time you visit a high-fidelity store. You'll see a lot of models on the shelf. All sizes.
All shapes. All colors. All costing more than the original.
The Phase Linear 700 started it.
Since we started it all, we were able to advance in an orderly, cost-effective manner, and improve on our original technology. There's no tab to pick up No penalty to pay.
The result is the Phase Linear Series Two.
The line is highlighted by the new Dual 500, rated at over 500 watts per channel, with distortion at an incredible 0.09%.
Designed to handle speaker impedances down to 2 ohms, the Dual 500 easily adapts to rugged professional use, or demanding home applications. A self contained, thermally activated cooling system, combined with an instantaneous LED display incorporating built-in output clipping indication, allows for precise power control. Electronic energy limiters and independent fusing of the power supply prevent the Possibility of damaging overloads.
Affordable Technology.
This same dedication towards exceptional performance. design and affordability is found in each Series Two Power Amplifier. From the-Kilowatt to the fully complementary output, Bi-FET process and nigh-loop gain-technology of the Phase L near 200-Series Two, there is an affordable original that easily fulfills your most demanding requirements.
Optionally available in Standard D.A. rack mount configuration. Solid Oak or Walnut side panels optional.
Output Power Minimum RMS per channel into 8 ohms from 20Hz-20,000Hz with no more than 0.09% Total Harmonic Distortion.

HOW TO DISTINGUISH BETWEEN THE SO-CALLED CAR SPEAKER AND THE FIRST CAR SPEAKER THAT DESERVES TO BE SO CALLED, The best of-he so-called car speakers, on the left, is identical in principle to a fine 'lone speaker.
The Audiovox Comp 60,"on the right, approaches sound from an entirely different paint of view The car.
Ifs easily distinguishable from the so-called car speaker in that it comes in two parts. Ole, a super efficient, low mass mylar midrange/ tweeter for high definition and clear high and middle frequencies And two, a beefed up 6 1/2" woofer for beefed up bass sound.
The reason the incredible Comp 60 is a breakthrough, c6 well as a break apart, is simple. It's the first speaker to put the midrange/tweeter where it should go in a car. In the front. And the woofer where it should go. In the ear. The result is the treble sounds, which are highly directional, get pointed at you, instead of at the back window. And the bass sounds, which are not highly directional, can spread out and move forward to meet the treble at an ideal point in the car. Your ear.
Of course, to be perfectly honest, the Comp 60 does nave a few features in common with a fine home system.
Like a circular woofer for clean bass response. And a dome tweeter for uniform sound dispersion. And a copper wound high temperature voice coil that can take the heat in the music without going to pieces. And heavy weight ceramic magnets that total a big 60 ozs. for a maxi mum of efficiency and a minimum of distortion.
Besides a handling capacity of 40 whopping watts per channel. And a frequency response of from 50 to 20,000 Hz.
The Comp 60 also has some parts no home system has. Like butyl rubber edges and gaskets to provide vibration-proof, jounce-proof damping.
If you want to get as much pleasure from your car speaker as your home speaker, make sure you get a lot more than a scaled down home speaker for your car. Get the first real car speaker. The Audiovox Comp 60. The speaker we took apart because of the way your car is put together.

THE SECRET OF THE WORLD'S FINEST CASSETTE DECKS IS ON THIS FRONT PANEL.
It's our name: Sanyo.
Take the cover off of almost any fine cassette deck, and chances are you'll find Sanyo parts.
Our tape transport mechanisms and electronic components have earned such a reputation for quality and reliability that they're used in some of the most respected equipment you can buy.
So when Sanyo set out to design our own cassette deck, we had plenty of technology and experience to draw from
The proof is in the state-of-the-art specs: 30-16,000 Hz response (± 3dB, CrO2 tape). 63dB signal-to-noise ratio with Dolby. And an imperceptible 0.05% wow and flutter (WRMS). Plus convenience features like a peak limiter to pre vent distortion, and a standby switch that lets you use an external timer to start recording even when you're not home.
If you need more proof, check the test reports. The RD5300 is generating the kind of enthusiasm you would expect for really exotic, high-priced components (phrases like "best buy" keep popping up).
So why should you buy a quality tape deck that's only part Sanyo. When for the right price, you can get the whole thing?

WHICH TAPE DECK SHOULD YOU BUY?
All product specifications from published company sales literature.
Price information from High Fidelity. August. 1977 issue.
The four tape decks compared above are all fine pieces of equipment.
But look closely at the table above and you'll see why the Fisher CR5120 is the most outstanding value in cassette decks today.
You can actually get a Fisher professional quality 3-head deck for about the price of many 2-head decks.
What you don't see in the table is the superb Fisher engineering that built this high-priced performance into a medium-priced tape deck.
For example, we engineered separate record and playback heads into the CR5120, not only to significantly improve recording quality, but also to permit monitoring directly off the tape--the only sure way to get professional recordings every time. All three of the CR5120's heads are made of glass-hard sintered ferrite for virtually unlimited life, without deterioration of sound quality.
The CR5120 even includes dual-process Dolby--separate Dolby circuits, one for recording and one for playback--so you hear fully de coded playbacks when you're monitoring a recording. And a Dolby FM switch with 25 u-sec. de-emphasis con version lets any tuner or receiver handle Dolbyized FM broadcasts.
To assure virtually perfect tape motion, the CR5120 uses a DC servo-controlled Hall-effect motor In the dual capstan transport, plus a separate DC motor to drive the reels.
Other CR5120 features are: source/ tape monitor switch, VU level meters, LED peak indicators, switchable limiter to prevent overload distortion, memory counter, and lighted mode indicators. All for about $400.
Which tape deck should you buy? See a Fisher dealer and try the CR5120 for yourself.
Flip the source/tape switch and compare the source and recording while you're listening--the only way to really evaluate the performance of a tape deck (you can't do this on a two head deck).
Fisher audio components are available at selected audio dealers or the audio department of your favorite department store. For the name of your nearest dealer, call toll-free: 1-800-528-6050, ext. 871 from any where in the U.S. (in Arizona, call toll-free 1-955-9710, ext. 871).

Accuphase announces a new product concept: a preamp designed especially for records.
The Accuphase C220 is a new kind of component for the critical listener. More than that, it is a new engineering achievement one that produces a transparency and purity of sound rarely heard from records.
The C220 eliminates all auxiliary functions of the traditional preamp, other than those needed for record reproduction (thus eliminating the compromises inherent in accommodating other functions).
Its use of direct coupled Class A amplification in all stages, Ring Emitter Transistors (RETs) and symmetrical push-pull circuitry dramatically upgrades the sound quality of a fine record collection.
The Accuphase C220 has a built-in switchable head-amp which allows the use of moving-
coil cartridges; it has switches to match its input impedance with the output impedance of any cartridge.
Class A amplification with symmetrical push-pull circuitry is used in all driver stages of the C220.
Four RETs--a new device consisting of 100 transistors in parallel (400 in all )- deliver exceptionally low impedance, superior high frequency content and high power amplification. Distortion at each amplifier stage is less than 0.001%.
Total gain is 86 db-the highest gain of any preamp available.
The C220 is not inexpensive.
But like every Accuphase product, it is handcrafted to prove trouble-free and maintenance-free-an example of Accuphase planned longevity in an era of planned obsolescence.
Each year of our existence, Accuphase products have received highest honors and awards from all over the world. Every Accuphase product has become a classic.
Now we are pleased to intro duce the winner of the 1978 Grand Prix for audio products in Japan--the Accuphase C220.
It may look like a new kind of component. But we think you'll find it's really a new record collection.

The Laboratory Reference Series tuner.
Avery remarkable component-by itself or as part of a complete LRS system.
Although the LUX Laboratory Reference Series was conceived-and introduced-as a completely new concept in systems, we believe you'll find the LRS tuner alone merits special consideration.
At a glance, the 5T50 is strikingly clean and elegant.
The tuning display itself is digital, supplemented by what might be considered an advanced touch of nostalgia for the dial of old. One linear dial is calibrated in 1 MHz increments, and another provides for 200 kHz indication. However, instead of a pointer, LED's traverse the dials, giving linear readout of tuned stations.
Electronic tuning and memory.
Tuning is accomplished electronically, by a touch on either of two buttons. Station selection can be switched to either manual or automatic scanning mode, and tuning speed can be adjusted from slow to rapid. A further tuning option is provided through the tuner's C-MOS IC memory system, which stores seven stations in digital code. A touch of the appropriate button provides instant reception, with the station exactly center-tuned.
Tuning accuracy within 0.003 percent.
Tuning is always exact, no matter how you select the FM station. Using a quartz crystal frequency synthesizer instead of a tuning capacitor and coil assembly, the 5T50 gives a degree of accuracy (within 0.003 percent) and stability that cannot be found in conventional tuners. The station is received center-tuned and it remains that way-just as accurate and as stable as the FM transmitter frequency itself-which, for reasons of precision, is also referenced to a crystal.
But the utmost in design and performance doesn't stop here. From front end to output terminals, the 5T50 utilizes the best circuitry. For example, dual-gate MOSFET's in the RF amp and mixer. And a buffer circuit-which helps achieve outstanding image, IF and spurious response rejection follows the crystal oscillator. In the IF section, a ceramic filter plus two pairs of 4-pole block filters provide for excellent selectivity without sacrificing low distortion characteristics.
A double-tuned quadrature detector also keeps distortion low, at the same time protecting against signal overload.
And to assure excellent stereo separation (45 dB at 1 kHz and at least 40 dB at high and low frequencies), the multiplex section employs a Phase-Locked-Loop circuit.
Special tuning refinements.
To help you take advantage of this advanced internal design-which includes a Dolby" decoding circuit for Dolbyized FM broadcasts-we've included a number of advanced external features. So tuner operation is just as precise as performance. For example, a multipath check button lets you detect multipath distortion audibly-no need for an oscilloscope. There's also an antenna attenuator for adjustment if signals are too strong in your reception area.
For quick level adjustment when recording Dolbyized broadcasts, a 400-Hz test tone button is provided. The tuner output level is adjustable, along with interstation muting threshold. A digital display provides easy-to-read signal strength indication. And if incoming signals are weak, there's a high blend noise filter to assure low-noise stereo FM.
Other LRS components.
Of course, only you know if you're considering a new tuner at this time, or an entirely new system. If the latter, we'll simply advise you that the LRS system has carried the separates concept to "an extreme." That is, the preamplifiers have no tone controls-these are provided by the LAS graphic equalizer or separate tone control unit.
The power amplifiers are available with or without meters supplemented by a separate LED peak indicator. And if low distortion is important to you, the total harmonic and IM distortion of the LRS power amplifiers at rated power is no more than 0.008 percent. That's double-0 eight.
However, if a superb tuner is really all that interests you at this time, that's tine. Chances are you'll see and hear it as part of the complete LRS system-where it will look and sound the most impressive. Suggested price: $1,495.

ANNOUNCING THE SPEAKER NO ONE WAS WAITING FOR.
When people think of us, they think of receivers, tuners amps, cassette decks and turntables. No one thinks of us for speakers.
But with the major advancements we've made in our components, we wanted to make sure they would sound the way they were supposed to sound.
We tested and listened to the best three way speaker systems and found that almost all of them had remarkably inefficient mid-range speakers. And because 90% of the sound that you hear is in the mid-range, those inefficient speakers were making singers sound slightly nasal and applause sound like rainfall. So we developed our new LS-408A. Our goal was to eliminate the nasal sound, and make sure an ovation sounded like applause instead of rain on the deck of Noah's Ark You, of course, had no idea we were up to this, With the help of computers, holographic analysis, and the sensitive ears of our engineers we built an efficient mid-range speaker that could do those things. Then we put that technology to work building a woofer whose cone eliminates mumbling, along with a tweeter whose higher output would repro duce the sound of the singer's lips and breath.
It's everything a 325 speaker should be, except it costs less than $250', Arid, as crazy as this may sound, it was worth the wait.

Radio Shack STA-2000
After you've studied, shopped and compared, your reasons for selecting the STA-2000 receiver become obvious. We designed it ourselves and it comes direct from our own factory to deliver quality beyond reproach. Look at the acclaim or, better yet, ask someone who owns one, and you'll see how we succeeded. Its fine styling and precision controls are apparent. But the real story is in its circuitry … the extra-low-noise phono stage . …the sensitive dual-gate MOSFET tuner with PLL.
Visit your nearby Radio Shack for a copy of the reviews and hear for yourself what all the excitement's about. And see how far $499.95 can go! The Realistic STA-2000. 75 watts per channel, minimum RMS at 8 ohms from 20-20,000 Hz, with no more than 0.25% total harmonic distortion.
["noise figures rivaling those of many a separate (preamp) ... If any part approaches over-achiever status, it is the power amplifier ... The controls are unusually flexible"] High Fidelity Magazine, March 1977
[ "separation at mid-frequencies was an incredibly high 54 dB . .. usable (FM stereo) sensitivity point was reached with a signal of only 5.0 u-V excellent basic circuit design.”] Audio Magazine, March 1977.
