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.

JVC QL-A2 turntable

JVC Quartz Auto-Return Turntable features:

JVC Quartz technology - Low Wow and Flutter 0,025%

Dependable JVC Super Servo Frequency Generator

JVC Core - Less Direct Drive Motor

Auto-Return Convenience at Attractive Price


The QL-A2 delivers the same accuracy and dependability of all JVC Quartz units. In addition to its first-rate specifications of 0,025% wow/flutter (WRMS) and  72 dB Signal-to-Noise Ratio (DIN-B), it has an auto-return mechanism for added convenience. Remember, only JVC's advanced techniques can bring such low-priced perfection to your stereo performance.


jVC Quartz Technology

The basic circuit configuration of the QL-A2 is the same as the one used in the QL-F4. an accurate Quartz oscillator, JVC's Super Servo Frequency Generator and "no-cogging" Core-Less DC Servomotor are all included in the QL-A2. moreover, JVC's simplified circuits and advanced production techniques are abundantly used in its production, leading to dramatically improved stability and accuracy.

New One-Row Strobe

With the One-Row Strobe used with the QL-A2, you can visually confirm speed accuracy. Since the LED flashes on and off, synchronized with the frequency of the Quartz, the strobe pattern is always sharp and clean. And since the frequency is changed with the speed, only one row of calibration dots is necessary for communicating the information for both 45 and 33-⅓ rpm.



Dependable Auto-Return /Shut-Off

As you move the tonearm toward the record, the platter starts to rotate in our "Quick Play Function". When the leadout groove of the record is played, the arm automatically lifts itself up, returns to its rest and shuts the power off in the "Auto-Return/Shut-Off Function". Like the QL-F4, the QL-A2 can be operated as if originally designed for manual operation since its arm may be moved manually anytime. Other features include a Reject Lever that returns the arm during play and a Cue Lever to lift the arm up and down. The tonearm features the Angular Contact Bearing Oil-Damped Cueing, insulated arm/weight interface and more.

Rotel RD-850 cassette deck

RD850 is a full-feature cassette deck which makes quality tape recording easy and dlivers excellent sound reproduction from pre-recorded tapes

Incorporating Dolby C noise reduction,RD850 provides a Signal-to-Noise Ratio of 72 dB for virtually noise-free recording and playback. To make RD850 compatible with a wide range of pre-recorded tapes. Dolby B is also included. Bias settings for normal, chrome or chrome-equivalent, and metal tapes give flexibility in your choice of tape formulations. LED record-level meters and soft-touch controls make RD850 a pleasure to use. A microphone input is included for live recording.

Technical refinements include a precision tape transpport mechanism for accurate, transparent sound reproduction from all your favourite cassettes. An electronically controlled high-torque DC motor minimizes Wow and Flutter. To maintain optimum distortion-free musical reproduction. RD850 uses a Sendust record/play head. Exceptionally hard, durable and ideally suited to recording and playback applications. Sendust is the material of choice for high-performance cassette decks and gives RD850 an extra dimension of quality and musiclity.

Like all components in the critically acclaimed Rotel line, RD850 emphasizes performance, reliability, ease of use and attractive styling. It is an excellent complement to other models in the Rotel hi-fi range of quality audio equipment and represents outstanding value .

Dolby Noise Reduction

A severely limited Signal-to-Noise Ratio (in the 50 to 55 dB range with perhaps a 10 dB peak) has always been an inherent weakness of the cassette format. While the dynamic range of most live music lies in the area of 70 dB to 80 dB, cassettes with no noise reduction are capable of a 65 dB dynamic range at best.

Dolby B was a dramatic breakthrough in increasing dynamic range by lowering the noise threshold by up to 10 dB in upper frequencies (where tape hiss is concentrated). With the advent of Dolby C, a 20 dB improvement in Signal-to-Noise Ratio is possible, with NR extending a full two octaves beyond the range covered by Dolby B, and Dolby C delivers much more stable and accurate  response in the higher frequency ranges while eliminating harmonic distortion.

RD850 incorporates Dolby C NR to give you the full benefit of these significant developments. Dolby B is included to make RD850 compatible with the everincreasing library of pre-recorded tapes encoded using this system.

Sharp RT-3500C cassette deck

Stereo Cassette Deck with Dolby Noise Reduction and APFS system

Sharp's  newly developed unique Auto Program Find System.

Sharp's developed unique APFS finds the cue of every musical selection (non0signal part) on a music recorded tape. When the fast forward button is pushed while operating with the APFS switch ON, the tape stops at the beginning of the next musical selection automatically. When the rewind button is pushed while operating with the APFS switch ON, the tape returns to the beginning of the music and stops automatically. The APFS is ideal for the following purposes: When you want to select only a desired selection of music  on a recorded music tape; When you want to select the next musical selection during playback; When you want to repeat the same music..

Ultra-hard, High-quality MCF head

Long-life with excellent durability against abrasion is assured through employment of a strictly selected high density ferrite head; keeps efficiency semipermanently without deteriorating characteristics during long periods of use. Ideal shape and mirror finishing produced by a unique polishing technique assure extra smooth head surface. Produces steady high range characteristics, non-fluctuating low range characteristics and wide dynamic sound range. Also assures recording and playback with high grade sounf quality. Moreover shuts out external induction thanks to front shield structure.

Automatic changeover system for detecting CrO₂ tape

When a CrO₂ tape with additional sensing holes situated next to the breakout lug holes is inserted into the cassette chamber. Bias and Equalizer can be set automatically to the correct characteristics in recording and playback mode. Therefore, no manual operation of the CrO₂ tape selector switch is required. When using CrO₂ tapes of the old standard type, the CrO₂ tape selector must be used.

Dolby Noise Reduction System

The Dolby NR system is employed in the RT-3500C for reducing hiss noise. The noise reduction effect of the Dolby system, for example, is 10 dB at around 10 kHz. So annoying hiss noise doea not affect listening enjoyment. Thus, the Dolby system not only improves Signal-to-Noise Ratio , but correct cross modulating distortion remarkably, and assures unsurpassed quality stereo sound reproduction.

DC Servo Motor for Stable Rotation

The DC Servo Motor is employed for stable rotation in the unit. Assures recording and playback enjoyment without worrying about noise caused by vibration. Wow and Flutter and Power consumption are also reduced.

Elac PC-830 turntable

Getting back to basics

For all its seeming complexity, there are really only three basic requirements of any well designed turntable:

That the turntable platter rotate at a constant unvarying speed

The the tone arm enable the cartridge to trace the microscopic undulations in the record groove freely and accurately

That it be extremely reliable and trouble free.

The turntable proper

Let us examine the turntable mechanism first. In addition to rotating at an exact speed, a well designed turntable should be able to play a record with:

Minimum rumble - that is, it should not contribute any mechanical noise of its own to the music.

It should have undetectable wow and flutter. That means it must be free of slow and fast variations in pitch caused by momentary variations in speed.

Belt drive plus.

The primary cause of turntable rumble is the transmission of vibrations from the drive motor to the tone arm as it tracks the record.

Over the years, various methods have been devised to reduce rumble. Perhaps the simplest, most affective and reliable is the use of a belt drive system. By connecting an elastic belt from the drive shaft of the motor to the rim of the turntable platter, while the belt acts as a very effective mechanical filter damping out motor vibrations.

However, there is one drawback to this otherwise admirable system. It lacks sufficient torque or start up power to actuate the arm lifting and cycling functions quickly and efficiently.

To remedy this problem, Elac has designed an ingenious drive system with an idler assist called Belt Drive Plus, which is incorporated in the new Elac PC 830.

An idle wheel driven directly by the motor brings the platter up to speed quickly and indexes the arm over the lead-in groove of the record. As soon as the tone arm descends and the stylus touches the record, the idler is disengaged end the turntable operates in the belt drive mode only.

To reduce wow and flutter, the Elac PC 830 couples the motor to a heavy (4:4 pounds), dynamically balanced turntable platter. The mass of the platter in rotation creates a flywheel effect and very effectively smoothes out any momentary speed variations.

It's worth noting that the flat, precision ground rubber drive belt used in the Elac PC 830 is resistant to heat and humidity. Moreover, long term dimensional stability is insured through the use of an automatic belt release that reduces tension on the drive belt when the turntable is not in use.

Precise and continous speed monitoring is provided for via an illuminated strobe and a pitch control that is adjustable over a range of ±3% of nominal speed.

In addition, the Elac PC 830 satisfies another vital, but often overlooked, requirement of a well designed turntable. It incorporates a dual element, tuned suspension system that provides maximum isolation from external vibrations, thus rendering it virtually immune to acoustic feedback as well  as other sound bluring sources.

 The well behaved tone arm

Just as a well designed turntable should do nothing more than rotate silently at a precise, unvarying speed, so should the tone arm assume a completely bening role. Its only function, to present the cartridge to the record without let or hindrance.

But this is more easily said than done. For today's better cartridges play at such very low tracking forces, often 1 gram or less, that many tone arms are hard pressed to cope with them. As a result performance can be seriously degraded.

To operate properly at these very low tracking forces, a tone arm must be very light and rigid. In addition, it should have a very low moment of inertia, so as not to impede the movement of the stylus in the groove. But that's only the begining, a well designed tone arm should also have:

Very low mass, especially at the head where it counts most.

Very low tracking error. That is, its design geometry should permit it to remain as nearly tangent to the groove as possible, at any point on the record.

Skating or side thrust compensation to keep the stylus centered in the groove.

The ability to function properly with a wide veriety of cartridges

A cueing control for simple and precise manual operation

To successfully meet all these requirements. Elac has designed a superb new tone arm for the PC 830.

Special alloy, tubular construction makes it very light and rigid while significantly reducing mass. Freedom of movement has been optimized through the use of microprecision ball bearing races in both the vertical and horizontal pivos enabling the tone arm to perform faultlessly with most lightweight, high compliance cartridges.

To provide greater stability and further improve tracking, the tone arm is dynamically balanced which has the added advantage of making turntable leveling non-critical. The offset angle (geometry) of the head minimizes tracking error and a positive contact, slide-in cartridge mount permits precise adjustment of stylus overhang to further reduce distortion.

To insure perfect centering of the stylus, in the groove at any point on the record, a highly effective antiskating adjustment is provide for conical elliptical and CD-4 styli. Thus uneven groove wear and distortion are materially reduced. A viscous damped cueing  control sets the tone arm down gently anywhere on the record. And the same gentle lowering  action also comes into play during automatic operation.

The finishing touch

In the final analysis, however, any first rank turntable is more than a collection of features. It is a study in human engineering. It should respond instantly and effortlessly. It should enable you to play a single record or a batch of records whit a minimum of fuss and bother. In short, it should never get between you and the music .

Denon PMA-700V amplifier

Dual Super Non-NFB Power Amplification

The PMA-700V are high power amplifier equipped with a Dual Super Non-NFB power amplifier for crystal clear reproduction of digital sources. Added to his extremely pure non-feedback amplification system, the use of DC circuitry without a single coupling capacitor in the signal path from the MC input to the speaker output terminals and a new current mirror circuit in the voltage amplification stage, using high speed transistors with excellent high frequency response, all work to obtain a high slew rate of ±350 V/µsec.

Furthermore, a Pc 80W , Frequency Response 20 kHz multi-emmiter structured large chip power transistor is used for the output transistor. This outstanding output transistor and the mighty power source which greatly increases current supply capacity provide truly high power.


Pure Current Supply - decreases ynamic Intermodulation DIstortion Distrotion by 60 dB

The large size heat sink and toroidal transformer, as well as audio capacitors for large scale capacity (33,000 µF) increase momentary current supply capacity to the same level as high-output top-of-the-line separate power amps. The use of this Pure Current Supply circuit with Denon's original bridged block capacitor system suppresses dynamic Intermodulation DIstortion , and together with the high capacity power transformer provides high dynamic power.

Electronic Switches and Ideal Chassis Construction Eliminate External Noise

In order to eliminate the influence of magnetic and electrical noise, the chassis construction divides the power supply section and main signal circuitry at the heat sink, thus markedly reducing mutual interferences. In addition, electronic switches are used for the input se;ectors, reducing wiring and resulting in an ideal layout to make signal paths simple.


Two sets of Video Inputs

VCR or Laser Disc Video input selection is performed with a newly developed complimentary push-pull circuit which provides low distortion and wide range response (DC - 10 MHz ±1 dB) for excellent image transmission performance. One set of inputs is located on the back panel, and the other one is on the front panel for convenient use.

Akai AA-1030 receiver


The Akai model AA-1030 , is another machine that's packed with power.

Minimum 30 watts per channel RMS at 8  from 20 to 20,000 Hz with no more than 0,3% T.H.D. And frankly we're probably being over modest. It's certainly worth emphasising here that the power rating is a minimum. Typical samples, when measured with both channels driven at 1 kHz into 8 , should demonstrate quite clearly the importance of comparing specification in power output.

There's a delicately balanced flywheel for picking your spot on the waveband. And with AFC (Automatic Frequency Control) you get perfect FM centre tuning with completely drift-free reception. A low noise FET and 3-gang frequency rectilinear variable capacitor in the front end eliminate intermodualtion distortion for clear broadcast reception. Ceramic filters in the FM IF section give better reception of weak signals. IHF sensitivity is 2,0 µV. The Phase-Lock-Loop circuit produces complete stability with separation better than 40 dB

As with the AA-1020, the AA-1030 also has variable FM muting to let you select not only the strongest stations and the weakest stations the tuner can pick up, but any point in between as well. There's also a level adjuster to allow you to cut out local atation interference. There are separate bass and treble tone controls; loudness switch; high and low filters; the same comprehensive tape dubbing facilities as the AA-1020 (you can connect two tape decks for simultaneous recording from a single source and Tape monitor 1 has parallel DIN and phone connections), two sets of phono jacks; aux jacks; connections for two speaker systems; FM and AM antenna terminals and a distance/local switch.

Pioneer CS-E400 loudspeakers


A compact 2-way , 2-speaker system with perfectly-matched woofer and tweeter and unique free-heating cone paper

Pioneer has matched z compact bookshelf design with superb sound quality in this speaker system, one that is ideal for most any home music system of medium power characteristics. Each enclosure is equipped with a powerfull 8-inch woofer and dome-type tweeter with fine directional characteristics to deliver natural, compliant sound reproduction al. All times. The speakers tale up to 30 watts of input power and give a frequency range od from 35 to 20,000 Hz . Either bookshelf or wall-mounted, or free-standing, the CS-E400 speakers make a valuable sound addition for the hi-fi fan seeking quality sound at a practical price.


Dynamic Bass Response

Only a very large speaker can equal the bass response that is a standard feature of the CS-E400 units. The reason is Pioneer's use of a 8-inch woofer in each enclosure plus revolutionary L.B cone-paper. This cone paper was developed only recently after many years of research and has been hailed throughout the audio world for its clear distortion-free reproduction. Tou will hear the difference with the very first recording you play through these speakers.

Smooth , Clean Highs

The CS-E400 speakers feature dome-type tweeters for high-range frequency reproduction. The sound is clean, precise, brilliant - just the way you'd expect it to be in speakers costing much more. The tweeter diaphragms are manufactured from quality animal fibres and a special treatment to increase intrnal loss. The treble reproduction is thus extremely natural with excellent directional characteristics.


Advanced Characteristics

The woofer and tweeter components are perfectly matched for balanced reproduction. Frequency Range is a wide 15 - 20,000 Hz and the system features excellent transient and intermodulation distortion characteristics. The combination of these acoustical characteristics makes for a quality of sound that is unmatched by any speakers in the same price range.

Unique Versatility

The CS-E400 system is designed for a wide range of uses - both as an independent system or for use in a 4-channel stereo system. Compact, beautifully hand-finished , the units may be wall-mounted for background music speakers or used as extension speakers for a large sound system.
