Lowther Classic 400 loudspeakers

 The Lowther Classic 400 is one of the company's most spectacular achievements in sound propagation. It employs Lowther's well known internal folded horn principle developed here to a mathematically ideal tractrix curve. This is completed by carrying the sound waves between a wall and the sides of the cabinet to finish as a quarter wave. The cabinet is positioned so that the output from the internal horn is directed towards a wall corner or comparable position acceptable to the room acoustics. A second drive unit in an acoustically coupled compartment serves as the forward facing sound radiator. A five-step ambience control enables the Classic 400 to be ideally matched to suit its environment and the preference of the listener.

Two identical drive units are used in the Classic 400. these are the new hand built PM6's having improved magnet and cone systems and special phase stabilising. No electrical cross-over is used between the units. They are acoustically matched by the unique design of the finely styled cabinet. The Classic 400 will be found compatible with practically any good amplifier in the ten to hundred watts output class although sensitivity is so good that as little as two to three watts can be sufficient for domestic listening needs.

Lowther Audiovector speakers

 The finest loudspeaker in the world

The Audiovector is a specialist high performance model embodying all the most sought after virtues in loudspeaker design and performance. Two Lowther drive units designed and made specially for the Audiovector are housed within an acoustically balanced cabinet interior as carefully made as any fine craftsman built organ. This Lowther loudspeaker need no recommendation for being "particularly good on strings", on "male voice" or extremely high or low audio frequencies, for example. The Audiovector renders them all with an astounding faithfulness to create compellingly new listening experience. Only the signal fed to Audiovectors can of itself impair the quality of what is heard. For the intelligent seeker after perfection, the Audiovector alone should satisfy.

Harman/Kardon 400XM cassette deck

 High technology metal cassette deck

The hk400XM is our top of the line cassette deck, and offers you the best of both worlds. High performance. And the sophisticated operating controls normally found only in professional equipment.

To start with, the 400XM is the most sophisticated design we ofer, with Dolby HX headroom extension, soft touch solenoid controls for fast, easy transport control, a two-motor transport for low wow and flutter (only 0,03%), and a 3-head configuration for simultaneous monitoring during the recording process.

Frequency Response is flat (±3 dB) for 15 to 20,000 Hz, with a Signal-to-Noise Ratio of 68 dB, using Metal tape and Dolby circuitry.

The 400XM's separate bias and equalization controls, tone generators and playback calibrators allow you to control all facets of the recording process for perfect results no matter which tape formulation you choose. LEDs indicate headroom safety to prevent saturation. We've even included a special shifting Dolby mark on the record level indicators. With conventional tape formulations, the Dolby mark remains in its normal position. But when metal tape is used, the Dolby mark automatically shifts upward to remind you of the new, higher setting you can use.

In addition to our Auto Program Search System, which lets you scan forward or backward automatically to sample each selection on the cassette, the 400XM also features an auto rewind/replay system. Engage the rewind system and when the tape ends the deck will automatically rewind the tape to its beginning. With both rewind and replay engaged, the deck will replay the tape automatically, too, rewinding and replaying each time the cassette ends.

Pioneer SX-880 receiver

Stereo Receiver with DC Power Amplification

DC Power Amplifier

"DC with a Difference" Power Amplifier Pioneer Solves the TIM Problem

The adverse effects of Transient intermodulation Distortion, or TIM, are devastating to the delicate waveforms which make up musical signals on their way to your speakers. TIM accounts for the "muddy" quality of the music you reproduce through conventional audio amplifiers, those with the old-fashioned AC circuit configuration using capacitors in their NFB or Negative Feedback loops.

Pioneer's "DC with a Difference" power amplifier circuity found in our best amplifiers and receivers solves the TIM problem. Other forms of distortion, too, are eliminated by the fact that we use no phase-dalying capacitors in the NFB loops, but - and this is important - we retain the capacitors in the inputs.

Advantages include;

Connected speakers are protected from DC-caused breakdown without the assistance of an overly elaborate (and unnecessarily expensive) special protection circuit.

Tonal quality is not harmed by DC in any way.

Our use of selected input capacitors ensures that tonal quality is maximized at all times over the widest possible frequency range.

Low-frequency transient current, generated inside the preamp section when the unit is turned on and off, is eliminated. Noise is entirely avoided.

Musical quality is never threatened when you play warped records.

 

Power Amp Circuitry, Supply and Protection

The power output section circuitry of the SX-880 has a current-mirror-loaded differential amp input and a constant-current-loaded, Darlington-connected, direct-coupled OCL output. Two discrete power transistors in each channel are supplied from a large transformer and two 15,000 µF capacitors to ensure plentiful reserve for maximum dynamic range. A large heat-sink, and a newly-developed Pioneer IC (PA-3004), are among the sophisticated touches which guarantee stability and full protection. The IC, in fact, not only safeguards speakers and circuitry from abnormal DC potentials at amp output terminals, it serves also as a muting device to and power on/off noise. The circuit is entirely self-restoring

 

Twin Power Meters: Instant-by-Instant Readout of Left/Right Chanel Power Delivery

Here are two functional meters which more definitely , not "just for show". You can drive your speaker systems at their best-sounding, best-performing levels by observing the logarithmically-compressed scales of the twin power meters on the SX-880. they display instant-by-instant readouts of the power output in each channel over a range of 0,01 to 120 watts each.

 

Pioneer-Exclusive IC for Stereo Demodulator

The PA-101A, an integrated circuit with astonishing capabilities, is another example of how Pioneer's leadership in hi-fi technology benefits you. In the FM section of the SX-880, this remarkable IC serves as a part of the PLL stereo multiplex demodulator.

But it also contains a very special device to automatically cancel the 19 kHz FM pilot signal; if an ordinary filter were used for this job, it would severely limit frequency response in the highs. So, instead of the typical 15 kHz or lower cut off, you'll hear clean highs with flat response up to 20 kHz for truly hi-fi results.

 

Low-Pass Filter with 23 kHz Cut-Off

Since all 19 kHz signal components are cancelled by the Automatic Pilot Signal Canceller, mentioned above, the low-pass filter following the IC is required to filter out only sideband components. In the 23 kHz to 53 kHz range, on the main carrier. Thus audio range is never squeezed nor lopped off at the top.

 

High FM Sensitivity; Not Just a Promise

The high 1,8 µV sensitivity of the FM section in the SX-880 is not just a meaningless specification, nor is it an empty promise. You'll pull in the station you want no matter how distant its transmitter or weak its signal, and enjoy the highest possible sound quality in the bargain. Circuitry in the FM front end includes a three-transistor configuration with a dual-gate MOSFET in the first stage.

 

FM IF Amplifier; Excellent Phase Characteristics

Another state-of-the-art. IC is used to achieve sufficient gain and beter limiter characteristics in the FM IF amplifier of the SX-880. it is circuited between three two-pole ceramic filters which have excellent phase characteristics. One indicator of the superior performance of this design is found in the high capture ratio of 1,0 dB or better.

 

Superior Distortion/Noise Specifications for Better Listening

The three important functions of the Pioneer-exclusive IC in the FM tuner of the SX-880 are IF amplification, muting and FM discrimination. Proof of the ICs extraordinary performance is found in the listening. Distortion is a low 0,07% (mono), 1 kHz, 65 dBf. And the noise factor, expressed as an 80 dB or better Signal-to-Noise Ratio at 65 dBf, cannot be bettered in any other receiver in this price range.

 

Pleasing AM Sound; High Sensitivity and Signal-to-Noise Ratio

Pioneer has lowered noise, sharpened sensitivity and cleaned up low-frequency response to make AM pleasantly listenable. An IC and a newly-designed AM ferrite bar antenna are among the touches which raise sensitivity to 300 µV/m and the Signal-to-Noise Ratio to an excellent 50 dB.

 

Low Distortion Preamp

Phono Equalizer; Definitely High Fidelity Performance

Hi-fi purists still insist that the disc record is the only "true" musical medium for wide dynamic range and realistic Frequency Response . Reproducing disc-recorded musical signals on the RIAA

Equalization curve over the widest possible frequency range is possible in the SX-880 thanks to the use of a voltage-proff IC, very low-error resistors and capacitors and other top-quality parts. Phono overload is 200mV at 1 kHz, with only 0,05% T.H.D. or less.

 

Capture Ratio Tone Control: "OFF" Positions Ensure Ruler-Flat Response

The Bass and Treble tone controls each have a center-clicked position marked "OFF" which doubles as a "defest" to ensure a ruler-flat response. The tone control amp is of the Capture Ratio type for ideal response, low noise and low distortion. There is also a Capture Ratio-type Subsonic Filter with a low-cut frequency of 15 Hz, 6 dB/ot.

 

A Complete Music Control Center

You'll appreciate the versatility of the SX-880 all the more with use. The simple-to-operate controls include:

Tape Monitor/Duplicating switches, permitting monitoring of Tape-1 or Tape-2, dubbing from either deck to the other (even as you listen to Source), and direct recording into either or both decks from Source

Speaker Select switches, independent off/on pushbuttons for System A and B

FM Muting switch to end inter-station tuning noise

Mode Switch for Stereo or Mono

Balance switch has click-stop in center

Loudness switch for natural response at low volume

Sony leadership in every aspect of audio and video reproduction is legendary. That leadership is no accident, nor is it recent. It arises from three sources. First, the vast Sony research and engineering facilities, among the most sophisticated in the world. Second, a commitment to a "total system technology" in the design of all our products. And third, a commitment to translating this approach into instruments for the home that incorporate advanced technology at a cost within the reach of the user.

All vital component circuit elements are manufactured in our own plants, according to exacting tolerances and stringent quality control. Our concern with quality extends to human engineering and painstaking attention to detail, including precision finishing of controls. With every Sony component, there's a touch of luxury and a special  degree of convenience.

When it comes to testing component performance, the Sony standard is also high. And so are performance specifications, even though we quote them conservatively. In fact  it's hard to find a Sony component that won't surpass its rated performance specs.
