JVC R-2X receiver

Trim and Slim with Quartz Tuning

Accuracy and convenience are harmoniously packaged inside the trim and slim cabinet of the R-2X. The most innovative of all the features is the "Digilog" tuning dial; while familiar looking with its frequency calibrations and a "pointer". It is digitally controlled by a powerful LSI. It spells extra convenience.

OCL (Output Capacitr-Less) design; Clear Reproduction Quality

In old capacitor-coupled power amps, reproduction quality was inevitably veiled by noise and distortion added by the output capacitors. By using a split-voltage power supply, we've successfully eliminated the output capacitors so that the speakers are directly coupled with the power amp.

Quartz Synthesizer that sings

Its Quartz-PLL tuning circuit means drift-free electronic performance. Accuracy is assured by use of a quartz reference and two ICs made to our own specifications. Tuning is accomplished by means of a set of Up/Down buttons which sing out every time they're touched.

Desired stations may be tuned in either automatically or manually; the former sequentially lets you scan the tuning band for only those stations above the muting threshold,  while the latter lets you capture any station, even the weak-signal ones below the muting threshold.

Six FM and six AM presets - extra convenience

Once committed to the Memory, you can recall any station with pushbutton simplicity. Memory backup (not requiring batteries) keeps memorized frequencies intact up to about a week if the power is shut off or the unit is unplugged.

31-LED "Dialog" tuning dial - a familiar face.

Your mind may say yes, yes to a digital tuner but your senses may say no, no because of its unfamiliar face. That's why we've  incorporated the unique "Dialog" tuning dial that looks conventional (analog) but actually operates digitally. As you tune (via the tuning buttons), the 31 LEDs shine, one after another to show you your position on the tuning dial.

FM/AM tuner features extra high signal-to-noise

The junction FET RF and four paired variable-capacitance diodes in the, front end are coupled with three newly-developed ICs in the IF and post-IF sections - one each for FM IF, FM stereo demodulator and AM-RF/IF/detector. As a result, the FM tuner features an exceptionally high Signal-to-Noise Ratio of 83 dB for FM mono. Contributing to this surprising figure is the non-switching "static-drive" circuit for the display, housed in an exclusive LSI.

JVC R-1X receiver

FM/AM Stereo Receiver - Low Styling, Medium Power, High Performance

In its trim, low-slung 95 mm high cabinet, the JVC R-1X features the cream of the latest JVC amp/tuner technology. Power is modest yet you can fill your room with clean sound from corner to corner. You'll appreciate the tuning aids that allow you to zero in on a wanted station quickly and accurately. Here are the details of the priced-right little big performer from JVC.

Output Capacitor-Less (OCL) - The end of capacitor distortion

Speakers are directly coupled with the power amp of the R-1X in an OCL configured design. The signal does not encounter a single capacitor to add distortion and mar musical enjoyment. Its class-A predriver is loaded by a constant-current circuit for still lower distortion.

Tone control is incorporated in the power amp.

The power amp also doubles as a tone control circuit, adjusting the amount of  NFB for various tonal shadings to taste. Absence of an active tone control circuit means less noise and distortion. Tonal adjustments are extremely natural sounding.

IC phono equalizer; accurate with flat response

The integrated circuit IC is used by JVC as a means to improve performance, assure re-alignment-free reliability, and eliminate any chance of instability. That's why we've used an IC for the phono circuit in the R-1X. This highly capable circuit permits accurate record reproduction with commendably low noise and distortion.

Tuner performance in FM and AM is clean and crisp.

Three ICs in the FM/AM tuner section make the R-1X a solid, reliable performer. One IC contains the FM IF amp, which assures low distortion (0,1% mono), high signal-to-noise ratio (82 dB). Another is found in the PLL stereo demodulator to keep distortion to a low 0,3% or less through the years. AM sound is pleasant and listenable thanks to still another IC for AM RF/IF

Tuning operation is simplicity itself

The tuning dial - with linear calibrations for FM - is wide and illuminated. A bank of five LEDs indicate signal strength, while a threesome of LEDs indicates the direction (left or right) you should turn the knob to accurately tune in the station for least distortion. A heavy flywheel makes tuning luxuriously smooth. It all adds up to unexcelled tuning ease.

Axiom AX 1,5 loudspeakers

 Inexpensive speakers tend to be studies in compromise, attemps to achieve smooth response with low-priced drivers and very simple crossover networks. Recently, however, the qaulity of models at under $500 a pair has dramatically increased, and the Axiom 1,5 is an example of minimizing both cost and compromise.

A 2-way system in a somewhat tall, narrow box, the Ax 1,5 is a very listenable reproducer. Response is +4/-2 dB from just over 500 - 16,000 Hz. Without the 7 dB bump at 400 Hz, response would be within these limits right down to 50 Hz, which is very respectable performance.

Top end response is elevated in a fashion similar to the AR but doesn't sound quite as etched. There are two reason for this seeming anomaly; first, though we reference our measurement to 1 kHz, this frequency is actually in a trough, so much of the midrange is balanced in level with the top  of peak, another dip being seen in the first overtone frequency range between 5 to 10 kHz. These characteristics, combined with the boost at 400 kHz, make for a quite natural balance, marred only by some midrange coloration.

In music test this manifested itself in the voice test as a mildly muffed quality and some edginess in female voice a result of the 4 kHz peak.

The surprise, however, in this speaker was the bass extension, down only 6 dB at 40 Hz and about 12 dB at 32 Hz. Measurements of exact cut-off points in bass response are always hard to make, especially in small speakers, because woofer harmonic distortion (or doubling) is high, and tends to be hard to separate from the fundamental. But there was appreciable pure bass below 40 Hz, so judicious placement, as well as reasonable levels, will provide excellent bass response from the 1,5. they should be mounted on stands about 20" high, but will not become boomy from corner placement because of the smooth bass curve.

Technics SL-D303 turntable

The Slimline Look Comes to Technics Direct Drive Turntables

Soft-Touch Electronic Front Controls

All the controls for the SL-D303 are lockated on the front panel for simplicity and convenience. Cueing, start, stop, speed, repeat, pitch control and on/off functions can be operated with the dustcover closed. Thus, no harmful particles can reach the surface of your records while you operate the turntable. Note that cueing is of the slide-bar type and the pitch control is styled in a rotational fashion. And the soft-control buttons are designed to require a moderate amount of pressure from your fingertips for activation.

 

High Performance Flat Direct Drive Motor

Like all technics direct drive turntables, the Sl-D303 have platters which are part of the direct drive motor itself. They are fashioned with a superior rumble rate of -78 dB (DIN-B) and minimal wow and flutter of 0,025% WRMS

 

TNRC - Helps Quiet Vibration and feedback

Vibration and feedback can be a problem with some turntable designs, but not with the SL-D303. technics has engineered them to be extremely stable against external vibrations and, at the same time, exhibit fine acoustical characteristics. With precision molded "TNRC" (Technics non-resonant compound), feedback is one of the last things you'll need to worry about even while listening at high volume levels. TNRC is actually an anti-resonant material developed by Technics to keep vibration and feedback to a minimum. There are upper and lower sections of TNRC which are strategically employed in the base construction of both turntables.

 

Gimbal Suspension

SL-D303 turntable is equipped with a four-point gimbal suspension system that's ideally designed for tonearm support. Precision engineering and for pivot-ball bearings lead to a minimal friction reading of 0,007 gram for both horizontal and vertical movement.

The support arms themselves are crafted of strong aluminum to assure rigidity and keep vibration to a minimum.

What's more, low friction plus the low mass of the tonearm itself make the SL-D303 compatible with most of the finest cartridges available today.

 

Sleek Tonearm Design

Along with their slimline styling, Technics has redesigned the tonearm assembly of the SL-D303. the arm itself has been lowered so it is closer to the chassis of the turntable. This is not found in most conventional turntables. Engineered with a single-molded headshell, the tonearm has a total mass of just 11 grams to ensure excellent sensitivity and low friction.

 

Full Automatic Tonearm and Disc Size Selector

A turntable should help prserve your expensive record collection. And one of the ways to ensure this is through automation. Technics SL-D303 does just that. With the disc size selector, all yo have to do is put on a record and press the start button. The turntable itself decides whether it is an Ep or LP and guides the tonearm to the correct lead-in groove.

Technics achieved such sophisticated automation through a fine synchronization between the tonearm control and a mechanical sensor built into the platter. It precisely notes the size of the record to be played and signals the tonearm accordingly. Thus, the tonearm moves to the correct position. And, even if you inadvertantly press the start button, the tonearm will not move unless the sensor detects the presence of a record. What's more, if there is no record on the platter, the tonearm will not leave the armrest, thus avoiding damage to the stylus itself. So, even if you make a mistake the SL-D303 doesn't.

 

Pitch Control with Illuminated Stroboscope

In the event you wish to slightly alter the speed of the turntable platter, Technics has included a front panel pitch control. This is especially useful if you want your music to match the pitch of an accompanying instrument. And, the illuminated stroboscope is provided to aid you in adjusting the SL-D303 with accuracy. You'll be certain that the platter speed is rotating at exactly 33-⅓ or 45 rpm when the markings on the rim of the platter appear to stand still to the eye.

Technics SL-D202 turntable

 

Slimline Direct Drive Turntable

When you select a turntable, you're forging an important link in your stereo system. It is a bridge between the one dimensional,vinyl world of your records and the acoustic realm of listening pleasure. That's why Technics has taken great care in engineering the SL-D202 turntables. Designed with the slim, sleek look of today, both the SL-D202, combine direct drive technology with the superior craftsmanship that has become a Technics turntable tradition. These one of remarkably dependable turntables have many features in common. For example, there's the integral-rotor platter direct drive motor for smooth, silent rotation, and the gimbal suspension tonearm. And the SL-D202 have tachnics non-resonant compound (TNRC) base construction which stifles vibration. What's more, there are electronic soft-touch controls on the front panel. All this adds up to two turntables with built-in reliability.

 

Semi-Automatic Tonearm

If you don't need the convenience an automatic turntable has to offer, Technics has created this semi-automatic turntable, you manually place the tonearm and stylus at the lead-in groove of the record. However, the tonearm automatically returns to the armrest when the side of a record is completed.

 

Additional features:

Pitch Control with illuminated Stroboscope

Aluminum diecast support portions for gimbal suspension

Precise tracking force adjustment with fine adjustments in increments of 0,1 gram, and antiskating control

Single-molded, aluminum diecast headshell.

Headshell stand
