Hi-fi Harmony--crown IC-150 and D-150A

80 watts per channel min. RMS into 8 ohms (1 Hz-20 KHz), total harmonic distortion of 0.05%. In any great vocal group, each singer could make it on his own. Together, they're beautiful.

That's how we designed the Crown IC-150 pre-amp and the Crown D-150A power amp.

The IC-150 provides precise control with minimum distortion. The D-150A provides reliable power to drive almost any stereo speakers.

Each one could be a superb addition to your system.

But together we think they're incomparably beautiful, whether you think of beauty as powerful, clean sound; or honest, uncluttered appearance; or simple, accurate control.

If the receiver or integrated amp in your current system seems somehow limited, please consider seriously the Crown IC-150/ D-150A combination. You'll be pleased at a new quality of sound, and surprised at a real bargain.

Write us today for the name of a dealer near you. It could be the start of a harmonious relationship.

Introducing Sound Guard.



The first product ever that protects records against wear, without resulting loss in frequency response or fidelity.

Every time you play a record you destroy some of its sound. The culprit is friction.

An inevitable result of a hard, diamond stylus tracking soft, vinyl grooves.

Under 200X magnification you can see the damage occur.

Tiny shavings of vinyl curl off the record like metal off a lathe.

You literally see sound being worn away. After repeated playings your ears begin to confirm what your eyes have seen.

Until now, no product could protect records against wear with out interfering with sound fidelity.

An answer from outer space From Ball Corporation research into dry lubricants for NASA's Orbiting Solar Observatories came a breakthrough in micro-coatings that can function for long periods under extreme conditions.

One derivative of this new technology is a microscopically thin, dry film that molecularly binds itself to vinyl. Developed in to a record preservative this product is now known as Sound Guard. How Sound Guard works Just spray Sound Guard on (it has a non-aerosol pump sprayer). Then buff it with the soft, durable velvet buffing pad provided in the kit.

Sound Guard puts an ultra-thin, dry film on the groove surfaces to substantially reduce wear. (It's self limiting and may be applied repeatedly without buildup. The film thickness is less than 0.000005".) One bottle will protect about 20 LP's.

Sound Guard is dry--not wet and sticky like silicone-type products--so dust or dirt won't accumulate on the stylus or in the grooves. And since it has an anti-stat built in, Sound Guard actually prevents records from attracting dust.

But does Sound Guard adversely affect frequency response or fidelity? For conclusive proof, we asked the most respected of the independent audio laboratories for an exhaustive evaluation. Their results were astounding! Test results

1. The application of Sound Guard to a stereophonic or CD-4 quadraphonic disc does not in any way degrade audible frequency response.

2. Sound Guard increases the life of the records by significantly reducing record wear.

3. Sound Guard significantly retards increases in random noise content (surface noise) and total harmonic distortion caused by repeated playing.

4. Records treated with Sound Guard do not attract dust as readily as untreated discs.

(Complete test results will be mailed with every order.) Like it or your money back We're understandably excited over this new product.

Along with audio experts who've tested it, we believe Sound Guard is the long-awaited breakthrough in sound fidelity protection.

As of now, the only way you can buy Sound Guard is by ordering direct. Just fill in the coupon (or write: Sound Guard, P.O. Box 3300, Muncie, IN 47302, USA) and enclose your check or money order payable to Sound Guard.

BIC--COMIN' ON STRONG!


The Beogram 4002.


A turntable unequalled in concept, performance, and design.

As you and your audio system gain in sophistication, you begin to define high performance far more critically. You also become sensitive to the many details which separate the good products from those considered exceptional. It is at this point that Bang & Olufsen becomes more important, and components such as the Beogram 4002 turntable are worth your careful evaluation.

 

Exceptional resistance to vibration. A leaf spring pendulum suspension system (patented) actually transforms horizontal shock into vertical motion, damped by the entire chassis assembly.

 

An extraordinary cartridge. The Beogram 4002 comes with the MMC 6000 cartridge, Bang & Olufsen's finest. It features an effective tip mass of only 0.22 mg., tracks at one gram, and has received critical acclaim throughout the world.

Electronically controlled tangential--Complete stylus protection. The raising and tracking. A sophisticated system operated by lowering of the tone arm is its own DC motor. It automatically controlled eliminates the problems of by a pneumatically damped, angular distortion, skating solenoid operated system force, horizontal and vertical friction.

Complete stylus protection. The raising and lowering of the tone arm is automatically controlled by a pneumatically damped, solenoid operated system which functions via independent electronic circuits.

CD-4 capability. An optional CD-4 demodulator/phono preamplifier can be installed in the turntable housing, the optimum location for CD-4 reproduction.

Stable, accurate drive system. A high torque DC motor with integrated electronic speed control drives only the turntable platter via a precision ground, flat rubber belt.

Complete stylus protection. The raising and lowering of the tone arm is automatically controlled by a pneumatically damped, solenoid operated system which functions via independent electronic circuits.

One touch music. A finely engineered control panel allows fully automatic operation (cueing cycle: 2 seconds) by depressing a single microswitch. Power assisted manual operation permits you to scan the entire record in either direction at fast or slow speed.

Elimination of warp wow. An extremely short, low mass tone arm, which weighs only 8.4 grams with cartridge, eliminates the distortion caused by warped records.

Everything you hear is true.

Power Output vs Distortion

Distortion vs Frequency

Tone Control Characteristics

FM Signal/ Noise Ratio vs Antenna Input Subsonic/High Filter Characteristics

It has all the power you need [at the lowest achievable level of distortion]: 100 watts per channel, minimum RMS 'both channels driven at 8 ohms, 20-20,000 Hz; with total harmonic distortion no more than 0.1 %]. The componentry used to achieve this rating features exceptional stability characteristics: a paralleled OCL direct-coupled out put configuration...twin 15,000 if filter capacitors...and a zener regulated secondary power supply.

It has all the controls you need for fully flexible centralized operation: 5-position Mode switch, 6-position Selector switch, 8-position Speaker switch. Two Tape Monitor circuits [with a two-way, inter-deck dubbing capability]. Front panel Mic Input and Mixing, with a frequency response suit able for use with a professional caliber microphone. And a Main-In/Pre-Out switch, which allows independent usage of the main amplifier section. You can operate two speaker groupings, two turntables, three tape decks and any auxiliary equipment -with no discernible white noise.

It has State-of-the-Art tuner specs: an IHF FM Sensitivity rating of 9.9 dBf [1.7 uV]. Four ganged tuning capacitors, dual-gate MOS FET's provide superior image rejection and spurious response rejection, with minimal cross modulation.

The digital detector introduces absolutely no distortion to the signal, and never requires alignment. The Ceramic FM IF Filters are matched for optimal phase linearity. The Phase Lock Loop integrated circuitry in the multiplex decoder improves separation and SCA rejection, while limiting distortion.

It has all the features you need for the purest sound: Loudness Compensation and Hi-Filter switches; separate detented Bass, Midrange and Treble controls leach with exceptional variance characteristics]; and a master Tone Defeat switch, for instant reference to flat response. FM Stereo Only and FM Muting devices. Dual tuning meters. And a Positune Indicator light, which visually signals perfect tuning.

It has switchable FM de-emphasis [25 u sec. and 75 u sec. I, to accommodate an outboard noise reduction unit. A built-in Ambience Retrieval System, which adds much of the extra coloration you get with true 4 channel sound. And a 4-channel adaptor circuit, which makes it easy to convert to the real thing.

It has plug-in driver boards [to facilitate servicing), which feature a single package differential amplifier, for stable operation regardless of temperature fluctuations.

It has relay speaker protection circuitry, which automatically disengages your speakers, if a potentially damaging situation arises.

It has everything we've mentioned. It has some features we haven't mentioned.

It has a price of less than $650. Your Sherwood Dealer will have it on his shelf soon. [Or if you're impatient, get all the facts sooner, by writing to us at the address below.] Either way, it's worth waiting for.

INTERFACE:A It doesn't miss a beat. For me, transient response is crucial. That's why I chose the Interface: A. I needed a speaker/ playback system that would accurately reproduce drum tracks, exactly the way I put them down.

Interface: A sounds just like me.

A powerful bass kick gets missed by other speakers I've heard. But not Interface: A. And Interface: A catches even my fastest moves with extreme accuracy.

Light cymbal passages that used to go unnoticed stand out. Tom-tom resonance is crisp, at any volume, regardless of speed. Even my bass player is amazed at the bass response. Clear, without rumble all the way down to 32 Hz.

If you want to hear what you really sound like, check out the Interface: A. You can put a lot of drums in this little box.

$450 the pair, including equalizer Slightly higher in the West.

TANDBERG TCD-310---It beat the best in to world.


Recently a panel of independent test engineers rated 22 cassette machines from all over the world for the German technical journal "Hi-Fi Stereophonie." They checked 7 key specifications. Hum. Hiss. Distortion. Frequency response. Head adjustment. Wow & Flutter. Speed stability.

They gave their top rating for best recording and playback performance to the Tandberg TCD-310.We don't Ike to use superlatives in describing our equipment. But then what do you call the machine that beat the best? Here are some of the many features that makeTCD-310 so outstanding:

• Three motors: One hysteresis synchronous drive motor for constant and accurate speed; Iwo servo-controlled direct drive DC spooling motors.

• Excellent signal to hum ratio. (Unweighted signal/noise.)

• Expanded range peak-reading meters that accurately read your recording and warn you about distortion before it happens.

• Two flywheels and dual capstan closed-loop tape drive for absolute stability and tape guidance.

• Guaranteed performance, 2 year warranty.

We believeTCD-310 can produce the quietest cassette recordings in the industry. Ask your dealer for a demonstration of TCD-310 and all the other fine Tandberg equipment.

We think you'll give Tandberg your top rating too.
