Kyocera R-861

If receivers have something of a bad reputation among serious audiophiles, there's a good reason, in Japan, where everybody owns compnent high fidelity, nobody owns one-piece receivers. In fact, North America may be the only place where receivers represent a majority of the market.

For most Japanese audio engineers, receivers are strictly for export. They're not serious components at all. So receivers are designed by the second-string engineers. This explains why even companies with decent separates tend to load their receivers up with meaningless knobs, buttons, and displays.

The irony here is that  there's no reason why receivers must be second-class components. There's nothing to prevent a company from using the same common sense and judgement in receiver design as they exercise with separates. This is the guiding philosophy behind Kyocera receivers.

 MOS FETS in the Driver Stage

A rarity in receivers, Metal-Oxide-Semiconductor Field Effect Transistors (MOS FETs) are used in the driver stages of all Kyocera receivers for their superior transient response and isolation characteristics.

Pre-Out/Main-In jacks

While it is hard to find a receiver with pre-amp output/ main-amp input jacks nowadays,, all Kyocera receivers have them. So you can connect outboard signal receiver as part of an elaborate multi-amp system. That's particularly important considering the multi-room capability of the Kyocera Full-System Remote Control network.

Kyocera PL-910

 The Kyocera PL-910 turntable is not only the top of the Kyocera turntable line, it will stand in audio history as one of the finest turntables ever built. It incorporates the most up-to-date technology and materials to accomplish the age-old goal of all turntable designers; rotational stability and resonance-free performance.

 Consideration has been given to every last detail in the manufacture of this masterpiece, down to the actual construction materials themselves.  The plater, for example, has been manufactured on Fine Ceramics - to be precise, alumina-ceramics-proven to possess hardness qualities close to those of diamond - and vibration - attenuating characteristics far superior to conventional materials such as ordinary aluminum. This Fine Ceramics platter is placed in full planar contact with an aluminum sub-platter of a different resonance frequency, thereby dramatically reducing unwanted resonances. Fine ceramics is used further in the platter spindle and the thrust bearings of the spindle. These extremely hard thrust bearings are capable of supporting the heavy platter without excessive wear, creating an ultra-precise pivot point for extremely smooth rotation.

 The base chassis of the PL-910 is made of Ceramic Compound Resin (CCR) to  isolate the turntable itself from external vibration (mechanical and acoustical feedback). The "howling" normally experienced in the presence of loud signals from large loudspeakers is unheard of in the PL-910.

Although the PL-910 is equipped with a heavily damped powerful Dc-servo brushless motor, the actual drive system is via belt to remove any last possible doubt concering rotational stability.

 Features

Ceramic Compound Resin (CCR) base chassis successfully isolates external vibration.

A high-purity alumina-ceramics platter mounted in full planar contact with an aluminum sub platter with differnt resonance characteristics  creates an effective resonance barrier.

Dual-suspension system separates the turntable and tonearm from the sub-chassis to isolate any possible external sources of vibration.

DC-servo brushless motor belt-drive system.

Heavily-damped motor avoids the creation of internal vibrations. Self-illuminated strobe with on/off switch.

4 mm thick transparent acrylic cover.

Four types of optional arm bases to mount most high quality separate tonearms.

Kyocera R-851

"Very simply, our R-851 is not for everyone. Not for every dealer. Not for every audio buyer. Only for those who demand the best. Those who want sound that's pure and distinctive ... who hear subtleties other miss. For those discriminating listeners, the R-851 is well worth the quest."

Hear the silence before you hear the sound

Switch on the R-851, switch from one function to another. Try Phono,Tape 1,Tape2, Auxiliary. Back to Phono. Absolute silence (of course, you'll get sound on AM/FM). The silence is the mark of a great receiver. And great engineering. The kind of quiet an audiophile loves to hear.

Sound that takes you closer to the source.

We.ve turned on the R-851 for some very experienced - even jaded -  audio cars, and all we can say is it stops'em every time. The sound is different. The sense of being there is almost overpowering. All this comes from 85 watts per channel of power (with dynamic power far above this figure) and some of the most sophisticated circuitry in the business. Above all, it uses MOS FETs, the new breed of output transistors, in the amplifier section. They can handle the transients, the power surges, the power requirements of present-day sound  (and tomorrow's digital sound) better than bipolar transistors ever could and give you a sonic purity like no other (many claim MOS FETs have picked up the warm, rich sound of the great tube amps and gone a step beyond!)

Fine tuned for every audio need

From front end to output jacks, the R-851 offers every feature an audio enthusiast might want. The most commonly used controls are right up front - the more esoteric ones are placed behind a neat flip-down front panel. There's microprocessor controlled quartz-locked tuning with 14 station programmable memory (7 Am and 7 FM): automation station seek; fluorescent display panel; and two-way tape monitoring and dubbing.

Kyocera C-910 (1983)

The first control pre-amplifier based on digital age technology and space age materials.

Features

Single Stage Push-pull circuitry improves open-loop performance and requires minimal use of negative feedback.

Separate input level and output volume controls near the final stage achieve the best signal-to-noise ratio and dynamic range.

Ceramic Compound Resin base chasiss isolates unwanted vibration both from internal and external sources.

Built-in MC Head amplifier is encased in a completely separate block, shielded with non magnetic material.

Only select circuit components used, from ceramic capacitors to film capacitors to achieve atmost sound quality.

Newly developed Fine Ceramic Linear module preserves sound quality by preventing unwanted vibration and DCdrift.

Top-quality Linear Crystal Oxygen-Free Copper wires are used to minimize signal loss through cable wires.

Digital program sources are virtually free of noise, with dynamic ranges in excess of 90 dB. For a pre-amplifier to cope with this unprecedented audio quality required the full refinement of conventional audio techniques as well as a totally fresh approach to improving performance.

The C-910's circuit design begins with a highly simplifield all Direct-Coupled (DC) Single Stage Push-pull (SPP) amplifier configuration that eliminates the second voltage amplifier stage of the output section. The SSP circuit maximizes the advantages innerent in a MOS-FET circuit, but also provides a very high slew rate exceptionally smooth open loop response wide dynamic range and maximum signal-to-noise ratio. No capacitors are used for stage coupling which eliminates a principle cause of sonic coloration. The entire SSP circuit is then encapsulated in Kyocera's proprietary Fine Ceramic Linear (FCL) module to counter Microphonic Effect and to eliminate instability due to temperature variations. Unwanted vibrations are reduced further by mounting all the C-910's circuitry directly to a high-density, non-resonant Ceramic Compound Resin (CCR) chassis. The Kyocera C-910 lets nothing interfere with accurate sound reproduction.

Kyocera B-910 (1983)

Kyocera's DC high-speed power amplifier features dynamic power supply

for maximum power and sound quality.

Like its matching pre-amplifier, the C-910, Kyocera's B-910 Power Amplifier begins by taking conventional amplifier design a few significant steps forward. It uses a CCR base chasiss and an FCL module for the input stage both for the purpose of eliminating resonance. It is designed to deliver a continuous power output of 150 W per channel into an 8 ohm load or 200 W per channel into a 4 ohm load - more than enough to handle the sudden power surges that are often required for digital program sources. The high power and high current delivery ability of the B-910 is made possible by a huge power transformer to perform to its full potential an oversized honeycomb heat sink of very high rigidity has been included to effectively dissipate all heat.

In the B-910 traditional two-stage voltage amplification has been replaced by an Single Stage Push-pull (SSP) circuit that eliminates the second voltage amplifying stage. This and an output stage without a negative feedback loop combine to create the widest possible dynamic range in a power amplifier. The B-910 then uses Kyocera's proprietary Fine Ceramic Linear (FCL) module and Ceramic Compound Resin (CCR) base to prevent unwanted temperature variations from adversely effecting the amplifier's most critical circuitry.

Features

Utilization of a newly developed FCL module avoids sound quality deterioration due to unwanted vibration and DC drift.

High 150 W per channel at 8 ohm, 200 W per channel at 4 ohm.

Single Stage Push-pull circuit improves open-loop performance and requires minimum use of negative feedback.

Powerful over-sized power supply transformer with 600 VA core volume.

KYOCERA DA-710 CX

In may of 1983, Kyocera introduced a CD player with true 16-bit digital filters. Today, the competition's calling this circuit "the latest thing". Years ago we had four-times oversampling. This year every high-end player worth mentioning has a similar design. In september, 1984 Kyocera raised some eyebrows with the world's first Fine Ceramics anti-resonant CD chassis. Now the stores are full of flimsy imitations.

How did all these innovations happen to come from Kyocera, and not some household name? perhaps because kyocera's knowledge of digital circuitry comes fromyears of building computers for some of the best-known names in electronics. perhaps because Kyocera is a world leader in Fine Ceramics, the technology used to house circuitry in aerospace and other advanced applications. Or perhaps beacouse some top-rated CD players form other brands were actually made by Kyocera.

Now Kyocera has four world-beating Compact Disc Players, ranging in suggested retail price from $ 350 to the $800 model DA-710CX shown here. Each boasts technology so advanced, it's a preview of what the competition will be selling in 1989. After all, history does repeat itself.
