Nakamichi RX-303 cassette deck

 

Unidirectional Auto Reverse Cassette Deck

A 2-head , Closed-Loop Dual-Capstan record/playback auto reverse deck rivalling the RX-505 in top performance quality.


 

The RX-303 is designed with the same Unidirectional Auto reverse mechanism and high-precision transport employed in the RX-505, for exceptionally high reproduction quality. The RX-303 incorporates a triple laminated core Sendust record/playback head instead, yet provides wide, flat frequency response and extremely low distortion rivalling that of the Discrete Three-Head System. Low-noise, low-distortion amplifiers, the same as those used in the RX-505, ensure the finest possible reproduction performance, and the same Closed-Loop Dual-Capstan Transport silent mechanism guarantees incredibly accurate, stable tape travel characteristics. Extra operating control and convenience is provided with automatic fade-out and fade-in prior to and after the reverse operation, for smooth musical transistors between sides of a tape. A host of other features, combined with the outstanding reproduction quality of the Rx-303, make this deck a strong rival to the RX-505 in all-around performance.

JVC L-F71 turntable

Electro-Servo Fully Automatic Direct-Drive Turntable with Music Scan

 

Superb tracking and utmost operating convenience are happily and harmoniously combined in the L-F71 from JVC. E-D Servo damps arm resonance for better tracking, while applying anti-skating force accurately anywhere across the record surface. And for convenience, the JVC "Music Scan"  system automatically homes in on whatever track you've selected, there's nevere a need to touch the tonearm. Conveniences such as these weren't even thought possible just a few short years ago.

E-D Servo for horizontal arm movement; Damped resonance and accurate anti-skating.

By designing a straight, low-mass tonearm for the L-F71, we succeeded in damping arm resonance and subduing shock caused acoustic feedback. But we've made it still better by controlling its horizontal movement with JVC's exclusive E-D Servo. The L-F71 is totally and effectively protected against mistracking, coloration, poor bass response and poor stereo separation that can be caused by resonance.

 

JVC "Music Scan" for random cueing

Say you want to hear the third band on a record. Just push the Track button three times and then Start/Stop - the tonearm will automatically scoot over and set down exactly at the beginning of the third band and play through to the end of the record. Our special headshell houses an optical system that scans the record surface. An LED digital indicator tells you the number of the track being played at any given moment.

 


Computerized fully automatic operation via front-panel touch buttons.

Touch any of the operating buttons and the programmed to order microcomputer supervises the order of events flawlessly. Since the L-F71 is fully automatic, you need not touch the tonearm at any time. Up-front buttons are touch sensitive and may be operated even with the dust cover closed.

 

Smooth coreless DC servo motor and FG Super Servo

Our exclusive cog-free coreless DC servo motor and FG Super Servo speed control account for the superb performance of the L-F71.

JVC QL-F61 turntable

Quartz Locked Fully-Automatic Direct-Drive Turntable.

Advanced Tonearm Design to Complement Quartz Drive System

The QL-F61 is more than just sleek, slim and solid; it's jampacked with futuristic JVC technology. One example is the advanced Double Servo Quartz control to adjust platter speed with unerring accuracy. Another is the coreless DC motor that the servo control operates; iy's brushless, coreless and cog-free. The arm is of the low-mass straight line type for better tracking. For convenience's sake, the turntable is full automatic from cue-in to end of play and shut-off.

 

Smooth platter rotation is assured by the JVC-made coreless DC motor and Double Servo Quartz control

Our ideally matched motor and servo system achieve unimaginably low wow and flutter of 0,025% (WRMS). Signal-to-Noise Ratio is better than 75 dB (DIN-B). Never again will varying pitch, however infinitesimal, mat your musical reproduction, even if the record is of the latest direct-to-disc or digital variety.

 

Low-mass straight tonearm for lighter, better tracking.

The conventional high mass tonearm cartridge combination can produce harmonic distortion on the order of 10% when tracking even a barely visible record warp. But the tonearm of the QL-F61 reduces distortion to practically nil even on moderate wsarps because of its low-mass design. Low mass means a higher resonance frequency (slightly above the warp frequency), a reduced resonance peak, and higher sensitivity. The straight contour of the arm ends spurious movement of the arm due to dynamic torsion.

 

Up-front controls for your convenience

Gone is the cluttered lok that keps you away from the controls when the dust cover is closed. Along the front edge of the QL-F61 are all the operation buttons - "touch" buttons - for record speed, pitch control, quartz on/off, repeat, record size, start/stop and  even arm cueing.

Fully automatic operation with repeat.

Operation is completely automatic from beginning of play to end; there's never any need to touch the tonearm. This is a definite plus when there are kids around who may not be particularly adept at handling the tonearm. Records and stylus are protected. When you're in the mood, switch on the repeat function and listen to the entire side of a record over and over.

JVC QL-A51 turntable

Quartz-Locked Auto-Return Direct-Drive Turntable

The QL-A51 from JVC differs from the more expensive QL-F61 in only two ways; lack of both a repeat function and full automation. Otherwise it's the spittin image of the QL-F61, including the precision motor , straight tonearm and up-front controls. From the tip of its cabinet base, it's one of our most attractive models - and musical reproduction will be just as attractive resonance and mistracking have become problems of the past.

Our direct-drive Double-Servo Quartz motor has no core.

Double-Servo Quartz control - a JVC exclusive - keeps a constant check on the actual platter speed, speeding up or slowing down the motor instantly if any speed error is detected. Moreover, the servo motor is of our own design, made by us, and coreless to avoid cogging, the annoying rotational fluttering which can spoil music reproduction. Long-term accuracy and reliability are assured throughout this sophisticated direct-drive turntable.

 

Rigid, non-resonant straight-line tonearm.

Our tonearm is of the straight-line design for a reason. The reason is to better handle record warps and for clean low-frequency response which is even more important now that digital and direct0cut records are available. Vy being low mass, our tonearm keeps its resonance frequency above the warp frequency and the resonant peak itself is suppressed so that the lowest musical signals can be reproduced without a trace of muddiness. Mechanical strength is another important feature for surer tracking and better resistance to damage.

 

Up-front controls for all operations, including arm cueing.

Taking a design tip from the more expensive and elaborate turntables in our lineup, we've given the QL-A51 still more appeal with a system of simplified, up-front controls. All can be used with the dust cover closed. And unlike other models in this price range, even the cueing control is up-front. Every care has been taken to prevent unnecessary record handling - from the manual cue control to the automatic arm lift, return and power shutoff at the end of play.

Pioneer Elite PD-75 CD player

How a concept called the stable platter turned the CD upside down.

 

In airline pilots, brain surgeone, and CD players, steadiness is a pretty fundamental requirement. In the case of our newest CD player, the Elite PD-75, its rock-solid stability has rocked the world of music lovers and audio critics. As the reviews have rolled in and the awards have been bestowed, it is apparent that the standard for CD players has been advanced dramatically. Behind this success lies a principle that Elite has brilliantly exploited. The mechanical elements of a CD player are just as critical to its quality as its electronic components.

The first significant innovation to come out of this insight is at the heart of the PD-75. the stable platter.

Two basics of physics - mass and inertia - combine to make the stable platter an obviously superior platform to support a disc spinning at high velocity.

Next, the stable platter, by supporting the entire area of the CD disc, minimizes wobble and chatter.

A wobbling disc presents a difficult target for the laser, while a chattering disc creates resonance, distorting the signal, which distorts the sound.

Another problem for CDs is gravity. Spinning above the laser pickup and supported only in the center, the disc sags microscopically. Which to a laser beam is significant degradation.

But on the Elite CD platter, the disc is turned upside down - that is, label down, information side up. The disc lies firmly clamped to a solid surface. Meanwhile, the laser pickup reads the disc's digital code from above, where it is immune to dust settling on the laser optics.
