JVC L-A31 turntable

Auto-Return Direct -Drive Turntable

Features

Cog-free coreless DC servo motor

FG direct-drive system

Low-mass straight tonearm

Up-front controls

Auto return convenience and pitch control

 

Sharing many features with JVC's more advanced turntables is the L-A31. like every other JVC turntable, it has the JVC-exclusive cog-free coreless DC servo motor to smooth rotation and deliver high torque, and our FG direct-drive system to maintain speed accuracy. Rotational speed is constantly adjusted against any variations, whatever the cause. Our low-mass straight tonearm is consistent with current thoughts on the subject; low-mass improves tracking, allowing the use of even quality high-compliance cartridges. Its straight design further reduces mass and increases rigidity. Resonance is optimally just above warp frequencies while remaining below audible frequencies and our ultra-light non-resonating headshell is included. Operation is simple, convenient and smooth. Controls are up-front, outside the closed dust cover - even arm cueing. Cueing and end-of-play auto return are two amenities added to protect records and stylus. Record handling is reduced to a minimum. Other features are the built-in strobe and a pitch control for "tuning" your records. We're sure that feature for feature and spec for spec, there isn't a finer turntable available.

JVC L-A21 turntable

 

Auto-Return Belt-Drive Turntable

Features:

Quiet and accurate belt-drive

Precision synchronous motor

Low-mass straight tonearm

Up-front controls

Auto return convenience

 

The design objectives for our lowest cost turntable were for the most performance and features at a price easily accessible to anyone. Check the features and specifications of the L-A21 and you'll agree that we met all our design objectives. Our reliable belt-drive system eliminates vibration and noise and promotes smooth platter rotation. And our motor is an advanced synchronous type - impervious to changes in line voltage. Our tonearm, like those found on our more expensive models, is of a low-mass design for high tracking and low distortion while its straight tube design reduces spurious movement of the arm due to dynamic torsion. Our special headshell is non-resonant yet extremely rigid. We've also included a cueing device and the auto return mechanism. Like all its operating controls, the cue button is outside the closed dust cover so there's little chance of nudging the tonearm and damaging record or stylus . All in all, a great bargain at any price.

IMF TLS80 II loudspeakers

Based upon the world acclaimed Reference Standard Professional Loudspeakers, the Monitor TLS80 fulfills the need of the dedicated audiophile for a speaker of comparable quality, but tailored for home use.

Full transmission line loading incorporates new damping materials. Acoustic foam, as used in anechoic chambers, is "sculptured" to produce a wedge effect where the maximum surface area is exposed to damp the line, yet presenting the minimum of restriction. A separate midrange line is similarly terminated whilst standing waves are progressively absorbed by long hair wool. Both a tweeter and a super-tweeter are employed to ensure power handling conducive with wide dispersion and extended response beyond the limits of human hearing. Only a transmission line can provide the dynamic impact experienced in the concert hall. Bass is reproduced within the listening room rather than in a box. If there were a better method of loading, we would have employed it.

The whole system is integrated by a complex crossover, developed as the result of research in depth into the problems of phase correction, impulse response and amplifier matching. A three position "Tilt" control enables the energy response to be modified from nominally flat to "Rise" or "Fall", compensating for the location, the characteristics of ancillary equipment, or even personal preference.

 

 Like the Reference Standard, the speakers are designed to be used on the stands provided. These ensure that the loudspeakers are supported off the floor, reducing room colouration components. Importantly they slightly tilt the speakers back, maintaining a substantially flat response both axially and hemispherically.

 

 There is very little that need be said about the Monitor, which is both neutral yet exciting. Supplied in matched "mirror image" pairs the stereo presentation is stable, portraying great detail with the uncanny ability to reproduce the acoustic environment of the original performance. We suggest that you audition these speakers with the finest ancillary equipment. In the tradition of our monitoring approach to loudspeaker design the TLS 80 is capable of providing greater satisfaction over a wider range of programme material.

Acoustic Research AR-28B loudspeakers

This group of speakers - the AR -28b, -18b, and 8b - exemplify a fundamental belief we have held through nearly three decades of acoustic research. Listeners whose system options are highly restricted by budgetary considerations need not be deprived of true quality sound. These B-series acoustic suspension speakers use long throw woofers with energy absorbent diaphragms damped to an extremely low Q. the bass stays tight and clean, even at 100 watts of power on the 28b and 18 b, and 75 watts on the 8b. For added protection during peak power surges, the 1-1/4-inch high range drivers are cooled with magnetic fluid and fitted with S-Shaped lead outs.

A special feature of the 28b is a new 8-inch woofer that produces remarkably smooth frequency response in the mid-range, the critical aera for vocal reproduction.

Akai GX-210D reel-to-reel tape deck

Three Motor Automatic Reverse Stereo Tape Deck

GX-210D features 3-motor drive mechanism includes self-lubricating Hysteresis Synchronous Motor

To match the lasting performance of the GX Head, the GX-210D is equipped with Akai's unique self-lubricating capstan motor. The installation of two oil circulating mechanisms with cellulose fibres within the interior of the motor provides long lasting, trouble-free operation. Oil circulating speed is adjusted naturally according to motor revolutions and temperature, and because shaft rotation is always smooth and stable, various mechanical troubles resulting from oil circulation suspension do not occur. Further, these unique cellulose fibres also function as filters to keep the oil clean during the circulating process, adding to the motor's epoch-making longevity. Two highly efficient outer-rotor motors for supply and take-up reel drive assure consistent and smooth tape travel and ideal starting torque.

Akai 1730D-SS reel-to-reel

4-channel / 2-channel Stereo Tape Deck

An entirely new world of sound has been created by Akai's electronics engineers who have developed a new and sophisticated line of 4-channel surround stereo equipment. Included in this line are the exciting 1730D-SS 4-channel/2-channel Stereo Tape Deck and 1730-SS 4-Channel/2-Channel Stereo Tape recorder.

With either system, you're completely surrounded in sound with four speakers, left and right in front, and left and right in the rear. This system gives you a real "sense of presence", the feeling of being exactly in the middle of a live performance. Both models are designed to be used for not only 4-channel stereo but also 2-channel stereo as well.

The 1730D-SS is perfectly matched with Akai's exclusive AA-6100 amplifier. this amplifier has 80 W music power for dynamic 4-channel stereo sound and accommodates both 4-channel and 2-channel stereo operation.

 

Akai's dependable 2-lever system complements the high grade parts and robust construction of this rugged 4-channel/2-channel stereo model

It is regular practice to employ mechanical control in one-motor tape decks.  Akai has long since employed this 2-lever system in our one-motor decks. When compared to an ordinary 1-lever system, because the Play/Rec and F.Fwd/Rew Levers are independent, the movable range of the levers are shorter, and operation is lighter. Also, because the F. Fwd/Rew Lever is separate, mis-operation is minimized. Further, because of the mechanical structure of this control system, other parts are not unfavourably influenced and mechanism endurance is extended. Rectangular shaped Control Panel with proportionately balanced controls.

Akai GXC-325D tape deck

Dual Monitoring Cassette Stereo Tape Deck

With taped music, as in five card stud, you'll always get the results you want when you play with a deck that always delivers what you want. Take this deck, one of the new cassette decks from Akai.

The GXC-325D. It comes stacked with features to make your music sound clearer, and richer. It has a three head function, with separate recording and playback heads for wider frequency response. It comes with a closed loop double capstan, which maintains proper back tension, and perfect tapw and head contact.

 

The recording and playback heads of this new 3-head system are Akai's revolutionary GX Heads and are joined for perfect parallelism of recording and playback head gaps. This combined with the Closet Loop Double Capstan system and AC Servo Motor of this model clearly makes it the leader in the field of cassette recording.

Two each capstans and pinch rollers are used, one each of which is positioned in parallel at either side of the head block for stable tape speed and tape tension. This shuts out the adverse influence from outside the "closed" area between capstans so that there is no tape vibration and head-to-tape contact is perfect. Some of the other merits of this system include:

Perfect tracking and the elimination of azimuth alignment adjustment mechanisms, beacons, etc.

Better Signal-to-Noise Ratio and a wider dynamic range

Wow and Flutter reduced to 0,55% WRMS and sound drop-out minimized

3-head system facilitates Dual Monitoring and because of head portioning, there is no time lag between recording and playback signals during monitoring

Intermodulation suppressed for clearer playback

C.P.G. [Center Pole Frequency Generated] system of AC Servo Motor results in greater inertia and increassed output for extremely quiet operation and accurate motor revolutions
