ADC Sound Shaper Three equalizer

ADC has four Sound Shaper frequency equalizers that will improve your sound system. No matter how good it is. And at a cost that's lots less than trading in your components.

ADC Sound Shaper will improve your speakers. By extending thr true bass response, including the critical mid bass. ADC Sound Shaper will improve the relationship between your cartridge and speakers. From one of partial incompatibility to total compatibility.

They'il also eliminate rumble (low frequency overload), tape hiss and record scratches. And that only scratches the surface of what ADC Sound Shapers can do. For instance, the walls, carpeting and furniture of your listening room physically bounce sound around so that some spots have less sound than other spots. Lots less. ADC Sound Shapes will bring these "dead" spots to life.

Perhaps best of all, though, is a Sound Shaper's ability to let you re-equalize what a recording engineer mixed. If a horn section is overwhelming a piccolo, for example, you just slide the appropriate frequency lever. Presto, more piccolo. You can also vanquish a voice. Or boost a tube. Sound Shapers segment the entire spectrum of sound. To let you re-shape a sound track to your personal musical preferences. It's all the control you've ever dreamed of but never dreamed possible.

To get into equalizers, start with our Sound Shaper One which operates in five frequency ranges. Or our Sound Shaper One Ten which gives you greater control by operating in ten frequency ranges.

For more professional equalizers, there's our Sound Shaper Two MkII which functions in twelve frequency ranges with a two-channel LED meter And there's our new Sound Shaper Three Paragraphic Equalizer.

It combines all the advantages of a graphic equalizer with all the advantages of a perametric equalizer. Twelve primary frequency controls per channel. Plus twenty-four ancillary control positions per channel. The Sound Shaper Three is the ultimate in controlling and creating with your stereo system.

Take the ultimate step up in sound, without trading in a thing.

How To Trade Up Your Receiver, Tuner, Amplifier, Turntable, Cartridge And Speakers Without Trading In A Thing

Hitachi SR-1100 receiver

AM/FM Tuner Amplifier

No effort has been spared,no detail overlooked to make this one of the finest tuner amplifier available anywhere. From its FET equipped FM front end to its spring-loaded, one touch speaker trminal, every circuit and control has been designed with typical Hitachi fastidiousness. Accurate tuning is easy with signal strength and centre-zero tuning meters, and a muting control eliminates FM squelch. Further accuracy and clarity are guaranteed by ceramic filters and a time switching MPX decoder.

JVC JL-F30 turntable

 Fully Automatic Belt-Drive Turntable

Features:

Fully automatic Lead-in, Repeat, Return and Shut-Off

Four-pole synchronous motor

Proven Belt-drive system

New gimbal support

Cost and performance. The relationship between these two factors has always been a headache to designers/engineers. At JVC our engineers tried to create -and did - a balanced turntable in the JL-F30 for any serious audiophile, using our own 4-pole synchronous motor and the proven belt-drive system. It's no surprise that it has a low wow and flutter of less than 0,06% (WRMS) and a high Signal-to-Noise Ratio  of better than 67 dB (DIN-B). With the fully automatic convenience, the JL-F30 offers more performance for less investment than other automatic on the market.

The JL-F30's fully automatic mechanism allows manual operation at any time during play. An oil-damped arm up/down lever (CUE) is provided, so that you can cue on any of the selections on a record, regardless of arranged sequences.

The 4-pole synchronous motor spins the aluminum platter through the linkage of a belt-drive system. Vibration is filtered out and speeds are kept steady against power voltage fluctuations or load changes. JVC quality control is evident throughout this unit. The unit also offers the benefits of a low-silhouette design, making it perfect for any home decor, solid cabinet construction. Parallel isolating Suspension and other features.
