What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Aiwa AD-M800U deck

Stereo Cassette Deck

Only the very best decks have three heads. But Aiwa's metal compatible deck adds wireless remote control. And a brain DATA. Aiwa's exclusive microcomputer Digital Automatic Tape Adaptation.


The Data System

In less time than it takes to read what DATA does (…DATA does it). Set DATA's computer and press Start. LED's begin to flicker. One each for LH, FeCr, CrO₂, and Metal. DATA's electronic senses analyze the tape and an LED light up as the other go out. Now you (and DATA), know the kind of tape being used. Another LED flickers and lights. Bias is set for best frequency response using a built-in 6 kHz reference signal. The next LED flickers and lights Dolby levels are calibrated and set using a 400 Hz reference signal.

Two LED's remain. One flickers and lights. EQ-M is set, equalization for the mid-range 5 - 10 kHz. Then the next, EQ-H, equalization for the high, 10 - 18 kHz range is set.

Further down the panel an LED lights. It's green . You're ready to record. But, if the red LED lights instead, the machine's not wrong. The tape is. Get another tape or switch to amnual over-ride.

Once DATA is set, you record with maximum sonic quality, regardless of whose tapes or what type you're using. And Data stores the tape analyses - at your comand - in its memory bank. Four different tapes of your choice. Cassette recording was never so precise. So precise, and so fast.


It All Adds Up

Precise sophistication like Data deserves features and performance to match. You've got them, starting with built-in wireless remote control for full-function performance from across the room, using dependable, invisible infrared projection. You have 3-head performance using linear, ultra-hard sendust heads with Aiwa's exclusive V-cut geometry for contour effect elimination doing away with roughness at low frequencies. And each head is designed for best performance at its specific function.

Add Double-Dolby, IC logic controls, dual motor drive, backlif VU meters with 5-step peak reading LEDs, auto-repeat, memory replay, oil-damped eject and more.

The sum of the parts is frequency response of 30 - 17,000 Hz using Metal tape. Signal-to-Noise Ratio ratio of 68 dB with FeCr, Dolby on. Woa and Flutter is 0,04% WRMS.

This is one of the finest decks you can get at any price. If you prefer, it's avaliable in black with rack handles as the AD-M800BU.

Pioneer CS-5 loudspeaker

High performance Bookshelf Type 2-way Speaker System

The CS-5 is a superb, two-way, air suspension speaker system from Pioneer, the world's largest manufacturer of quality high fidelity speakers. It is an intermediate sized bookshelf system with a specially designed acoustic suspension woofer and a newly developed cone tweeter. Uniquely efficient for a system of this type, the CS-5 is still capable of handling 25 watts with remarkably smooth, linear response over the audible frequency range.


These speaker units are of unusually high efficiency, making it possible to reproduce sound at large volumes with relatively small power inputs, resulting in considerably lower distortion levels than is possible when amplifier - or receiver -  must be operated at increased power . In addition, the lower power requirements of the CS-5 make it suitable for use with almost every amplifier, receiver, or similar component regardless of its power output. The CS-5 will perform brilliantly even connected to a tape recorder or high fidelity compact.


The cabinet is finished in a rich, oiled walnut, beautifully crafted. The grille cloth is a pebble weave, strikingly handsome against the chrome inner frame and the walnut of this enclosure. The grille is readily removable to permit inspection of the speakers or a change of fabric to complement any decor. The back of the enclosure is fitted with a wall hanger to permit installation in a hanging position on the wall in addition to the usual horizontal or vertical shelf positions. The shallow depth of the CS-5 permits easy placement in any bookshelf location.


The woofer of the CS-5, developed specifically for this unit, features a newly designed cone that avoids break-up even at maximum power input, and has a specially developed cloth surround for greater compliance characteristics. It also features a high precision,long throw voice coil.  The resulting excellent bass is unique in an enclosure of this size.


An advanced design cone-type high frequency loudspeaker with excellent wide angle dispersion performance, this tweeter was designed to complement the woofer of the CS-5. the extremely linear response of this unit, together with its response to 20,000 Hz makes possible exceptionally brilliant, linear, and "transparent" sound, with unusual definition.

Pioneer CS-11 loudspeakers

High Performance Dual-Cone 8" Speaker in Compact and Practical Enclosure

Pioneer's CS-11 is no ordinary *-inch speaker system. The dual cone and carefully matched infinite baffle enclosure, slim type design, result in high fidelity reproduction that is not usually associated with systems in this class. Thus, this high efficiency system is ideal for a variety of uses - compact home stereo speakers, a background music system, and an extension speaker for sophisticated high fidelity systems. Complete with wall mounting bracket, in rugged synthetic resin, woood grain finish.


High Power Handling Capacity

Two other outstanding characteristics of this compact system are the power handling capacity and sensitivity. Power handling is a full 10 watts, which is quite a lot when you remember that for normal listening in an average room, one good, clean watt often suffices. Sensitivity is a high 94 dB/w. this means that your amplifier need not deliver a high output to get a strong speaker response. In other words, your amplifier can drive this speaker at the amplifier's lower distortion levels. The result to you is superior, distortion-free performance all-around.

8" Dual-Cone Speaker

The CS-11 is a new speaker system form Pioneer that features very smooth, clean response from 70 - 15,000 Hz. This is possible thanks to three main reasons. First, the 8" speaker is a special dual-cone type to significantly reduce distortion. Second, the slim type speaker system uses an infinite baffle enclosure to avoid spurious resonances and interference. Third, both speaker and anclosure have been matched with extreme care for optimum performance.

Contemporary Styled Cabinet

Smartly styled, the cabinet is of synthetic resin in a wood grain design. Unlike conventional wood finishes, this special resin is exceptionally rugged, scuff-re3sistant and scratch resistant. Looks good in any room. Attractive brown saran grille.

Very Versatile

Because this unit is ideal for home stereo, or where background music is desired, or as a high quality extension speaker. It has been designed for flexible placement. You may place the CS-11 horizontaly and vertically, or you may hang it from a wall. A practical mounting bracket is included for the latter purpose.

JVC JA-S44 amplifier



DC Power Amplifier in ICL Construction

45 Watts per Channel, Minimum RMS, both channels driven, into 8 ohms, from 20 Hz to 20 kHz with no more than 0,02% T.H.D.

S.E.A. Stereo Graphic Equalizer

Direct Readout Twin Power Meters

JVC Triple Power Protection

Twin Power Meters


Convenience and musical accuracy are the key features of this medium-priced, high-performance amplifier. With the JVC S.E.A. Graphic Equalizer built in, you can reproduce every sound equally. With its DC Power Amplifier, direct readout twin power meters and dependable power supply, the JA-S44 from JVC puts you Closer to the Musical Truth for less money than you'd expect. That's realJVC value. Its matchingtuner is the JVC JT-V22

S.E.A. Stereo Graphic Equalizer

JVC's S.E.A. Graphic Equalizer is in wide use because of its truly wide versatility. A live "tone-zone" S.E.A. such as on the JA_S44, permits a total of 371,293 possble tonal combinations. It helps you eliminate peaks and dips in the frequency responses of your cartridge, speakers or room acoustics; you hear the flattest - and most accurate - response in your room at your favorite listening position.

Covering up to ±12 dB in 2 dB increments the five "tone-zone" controls have center frequencies of 40 Hz; 250 Hz; 1 kHz; 5 kHz and 15 kHz. Thus you can adjust one segment of the frequency range without affecting others - which is a capability that ordinary bass/treble control cannot duplicate. To assure low distortion and wide dynamic range, we've employed, in stead of bulky hum-picking coils, what we call a "Semiconductor Inductor (L)". For further stability and reliability we built the S.E.A. circuit around ICs.

S.E.A. recording facilty. By operating the S.E.A. REC switch on the front panel, you can equalize frequency response as you make a recording on tape decks connected to the JA-S44

JVC JT-V22 tuner



PLL FM Multiplex Demodulator in IC Form

Long, FM-Linear Tuning Dial

Universal-Joint AM Bar Aerial


The JT-V22 FM/AM Stereo Tuner is a recommended match for JVC's latest JA-S model "DC" stereo integrated amps; JA-S55, S44, and S22. like the more expensive model, the JT-V22 performs as a radio receiver and as a high-fidelity audio component with equal excellence. Thus selectivity is as high as 70 dB, while distortion as low as 0,35% (stereo) and frequncy response flat up to as high as 15 kHz. JVC's sophisticated tuner circuit designs are everywhere inside the JT-V22 to bring you Closer to the Musical Truth.


FET RF Amp in Fronted

The frontend of the JT-V22 captures faint radio signals accurately and rejects all interfering signals effectively thanks to its FET radio-frequency (RF) amplifiers and a frequency-linear 3-gang tuning capacitor.

Selective FM/AM IF

In the FM IF we've employed an array of newly-developed ceramic filters that feature high selectivity and flat phase response for musical reproduction. The JT-V22 thus boast 70 dB selectivity and 0,35% Total Harmonic Distortion (stereo). The IF section for Am also has a new ceramic filter that improves. AGC (Automatic Gain Control) characteristics however high or low the strength of received signals, you're assured of clean, undistorted AM sound.

IC Construction for Complete Reliability

Three high-integration ics , one each for the FM IF, Pll Multiplex and Am RF/IF sections, guarantee dependability.  They never will require servicing. The PLL IC for stereo demodulation particularly improves stereo reception, making channel separation wide, distortion low.

Twin Extra-Large Tuning Meters

The JT-V22 features two extra large tuning meters, one for FM/AM signal strength and one for FM centre-of-channel tuning. Since they are responsive and accurate, you can depend on them to visually represent audibly ideal tuning.

Muting Switch

To make station selection comfortable we've equipped the JT-V22 with a muting circuit. And to permit you to receive faint signals below the muting level you can switch the circuit off.

Smooth-Tune Mechanism

Your FM listening fun depends a lot on a smooth-working, accurate tuning mechanism. For the JT-V22 we've provided an extra-wide 240 mm tuning dial with frequency-linear calibrations. The tuning knob is coupled to a heavy flywhell for fast scanning and easy pinpoint stations selection.

Universal-Joint AM Bar Aerial

The universal-join bar on the JT-V22 can be rotated in-nearly all-directions. Orientable it in the direction where you'll get the whine-free, beep-free AM reception. You may find AM sound is not all bad as you thought after all, with the JT-V22

Inside the chassis of the DP-60 , digital circuitry, such as the player, is electrically isolated from the analog circuitry by ultra high-speed, optoisolatora with a transmission capacity of 40 Mbits/second. In addition, special technology protects the internal circuitry from electromagnetic and static e;ectricity interference,, thus preventing the sound quality from being degraded by high-frequency noise. Carefully selected, top-grade 18-bit ICs are adopted for the D/A converters, each of which is precisely adjusted on the production line to achieve upper-limit performance. A 20-bit eight-time oversampling filter, the most advanced digital filter, is provided for both the left and the right channels. These digital filters are independent of each other and achieve an unnecessary bandpass attenuation of -110 dB and a bandpass ripple of ±0,00005 dB.


The DP-60 can boast a lot more of Accuphase's state-of-the-art. Technology though,, suh as a noise shaper that reduces re-quantized noise to near the theoretical lower limit, a 3-pole GIC lowpass filter with excellent amplitude and phase characteristics, a high precision digital deemphasis circuit with a deviation of ±0,001 dB and digital remote control that can adjust the gain up to -24 dB in 1 dB units.

Another feature of DP-60 is its rigid construction and high resistance to vibration and shock. The linear motor laser pickup is securely mounted on a diecast aluminium frame and the mechanism itself is fixed to a metal chassis of 1,6 mm thick, so that the vibration generated by the motor is almost completely absorbed. This construction brings the total weight of DP-60 to 14,5 kg, making it one of the heaviest CD player available.

The custom-built 8-bit microprocessor in the DP-60 gives remarkably short access time of 1 second or less.

The side panels of the Dp-60 use natural persimon board, following the design of the series of Accuphase models, with only the necessary switches on the front panel for ease of operation. Despite this implicity of appearance, the DP-60 has many convenient functions, such as "power On play" that automatically starts playback when the power is turned on, and a function to display and plaay back in units of one frame 91/75 second.
