Aiwa AS-S30 amplifier

Stereo Integrated Amplifier

Fifteen big Watts per channel of honest-to-goodness high fidelity sound from a 2-stage differential SEEP-OCL integrated amplifier an incredibly compact 7,1 cm high by 21 cm wide. Yet, the A30 has plenty of room to accommodate up to 4 external components including tape, deck, tuner and record turntable.

Power output has been boosted by use of a new extra-stable power transformer with independent coils for power and preamplifier sections, and enlarged heat sinks aid in efficient heat dissipation.

For low noise and dynamic performance from high quality MM phono cartridges, the improved phono equalizer IC has boosted Signal-to-Noise Ratio to an excellent 82 dB, with very low 0,005% distortion at 1 kHz. RIAA equalization is a remarkably precise ±0,2 dB throughout the 20 to 20,000 Hz frequency range. For well-balanced listening at low output volumes a switchable loudness compensation circuit is provided.

Aiwa SD-L30 cassette deck

Stereo Cassette Deck

High performance recording and playback in a tape deck less than 7,2 cm high

A full-fledged, full-performance stereo unit with every essential feature you'd expect to find in larger systems, the SD-L30 combines modern styling with an incredibly precise slot-in loading mechanism and reliable DC servo motor that makes you wonder why decks got so big and complicated in the first place.

Metal Compatibility

The ability to make recordings on high performance metal cassettes is no longer a luxury confined to high priced avantgarde models; Aiwa has modified the SD-L30's circuitry and boosted erasure power to ensure full compatibility with metal. Along with extended frequency response metal tapes will give such dynamic sound you'll want to use them for all your serious recording work. A tough long-wearing hard Permalloy record/playback head and dounble-gap ferrite erase head ensure trouble free performance from all tape formulations.

Optical Peak Display

Besides conserving space, responsive peak LEDs provide an additional measure of accuracy to take the guesswork out of record level adjustment. Signals are indicated separately for left and right channels in an easy-to-read 3-color sequence from -10 dB to +6 dB

Amazingly, the SD-L30 even has rear panel jacks to accommodate a pair of microphones for live stereo recordings

Aiwa ST-R30 tuner

AM/FM Stereo Tuner

An unpretentious tuner with some very impressive credentials, the R30 brings a new dimension in design and convenience to radio listening enjoyment.

Accurate Digital Display

Regardless of scale length, you're never quite sure where you're tuned with linear or rotary scales, because their graduations are usually too widely spaced to define tuning variations as close as 100 kHz (FM) or 1 kHz (AM). This alone is one big advantage of a property designed digital readout. For extra accuracy, the frequency counter IC in the R30's digital unit employs a quartz crystal which provides an unerring 6,4 MHz reference signal to ensure that tuning is held within a close ±25 kHz for FM or ±1,5 kHz for AM.

Superb Performance

For the best possible sensitivity and rejection of spurious signals, front end design employs a high stability cascade junction MOS FET. Moving on to the IF detector stage, outstanding 70 dB selectivity within 400 kHz is realized by use of ceramic filters specially chosen for the flattest possible group delay characteristics, which in turn has achieved low noise and distortion. Beautiful stereo separation (45 dB at 1 kHz) is maintained by means of a stable PLL IC in the MPX demodulator stage.

Superscope CD-302A cassette deck

Stereo cassette tape deck, features:

Built-in Dolby Noise Reduction System - with internal/external switching that enables it to operate as an independent out board playback Dolby system. Unlike most other Dolbyized units, the CD-302A Deck can also deprocess Dolbyized material from FM broadcasts and other tape recorders.

Automatic Shut-Off - that disengages the cassette drive mechanism at end-of-tape in record and play modes.

 

 

Recording Peak Limiter - that monitors and holds the recording level below saturation to prevent distortion while maintaining a full dynamic range.

Tape Select Switch - for proper bias and equalization when using either standard or chromium dioxide tape.

Mechanical Locking Pause Control - that enables you to pause during playback or recording without disengaging controls

VU Meters, Function Indicators and Cassette Compartment - that are illuminated for easy viewing

3-Digit tape Counter - with a reset button.

Walnut-Grained cabinetry - and the professional styling you'd expect to find only in more expensive units.

Sanyo RD-4300 cassette deck

Stereo Cassette Tape Deck

The perfect stereo cassette tape deck for audio perfectionists. This brand new Sanyo model contains Dolby Noise (Reduction) which almost completely eliminates annoying huma and hissing sounds that heretofore have been an unavoidable part of stereo cassette recording and playback. This advanced unit also has a tape select switch for nominal or high quality chrome tapes. Monitoring while recording is also possible and a cue control and full automatic shut off are built in. At the end of a recording a special memory counter returns the tape to the exact beginning of the freshy recorded material.

Other outstanding features include a pause button, output level control for lineout level, DIN connector and two large VU meters a panel that automatically rises up from the unit at the touch of a button. The Signal-to-Noise Ratio of model RD4300 with the Dolby switch on is 58 dB and the amazingly flat frequency response when a chrome tape is used is 20 to 18,000 Hz. An outstanding stereo tape deck for audio enthusiasts who refuse to settle for less than the best.

 

Features

Dolby noise Reduction

A simple comparison of sounds with the Dolby function switch on and then off clearly shows the value of this noise reduction circuit. Tape hissing and other irritating sounds and humming are almost totally suppressed.

Convenient cueing control, Auto Stop

Finding recorded sections of the tape during fast forward and rewind has been greatly facilitated with a built-in cueing device. There is also a full automatic shut off system that turns off the mechanism at the end of the tape during playback, recording, rewind or fast forward.

Tape select switch for ordinary and chrome tapes

This unit takes both chromium dioxide and ordinary cassette tapes. The wider frequency response of chrome tapes is rated at 20 to 18,000 Hz. A tape select switch is provided for differentiating between the two types.

Excellent sound characteristics

Wow and flutter of this model is 0,1% RMS, and the Signal-to-Noise Ratio when the Dolby switch is on is rated at 58 dB

Two large VU meters

For precision recording and playback two large VU meters are supplied. These meters are built into a special panel that tilts up automatically from the unit at the touch of a button.

Other

Other features include a pause button, separate record/play controls, two microphone inputs, a double eject system that allows you to check the amount of tape left without disturbing the playback or recording and a detachable plate for easy head-cleaning.
