THE ELITE A-91D INTEGRATED AMPLIFIER.
Now that the compact disc has taken the world by storm, ordinary amplifiers are failing their driving test. Because ordinary amplifiers simply can't handle the dynamic range and purer signal that digital sound delivers.
Fortunately, the A-91D is far from ordinary. Because the A-91D is built with one thought in mind-to maximize the performance of digital sound.
With 170 watts per channel into 4 ohm speaker loads, and 120 watts into 8 ohms, the A-91D unleashes digital's full dynamic range. Extra-large capacitors and huge finned cast-iron enclosed transformers further contribute to the A-91D's high current capacity and stability into speaker loads as low as 2 ohms.
Along with all this power comes unprecedented purity.
You can plug the latest CD players with optical outputs directly into the /91D, and reap the rewards of independent digital conversion circuitry with twin, glitch-free D/A converters, a digital filter with four-times oversampling, and an analog lowpass filter made 1h from quality discrete parts. The A-91D also uses Pioneer's exclusive Non-Switching-Type III amplifier circuit to totally eliminate switching distortion. What's more, critical signal paths are kept extraordinarily short for less electronic interference and cleaner sound.
When it comes to digital sound, there's no such thing as good vibrations. That's why the A-91D uses a special anti-vibration honeycomb design in the chassis frame. In isolation barriers between electronic sections. Even in all five insulator feet. A large aluminum volume control knob with a specially balanced brass shaft also absorbs distortion-causing vibration, and printed circuit boards are mounted in rubber for the same reason.
The A-91D is not only ready for digital, it's ready for the future. With six digital inputs (2 optical), and three digital outputs (1 optical).
So if you want your digital sound to drive you to new heights, you need to drive your digital components with the Elite A-91D.

Take out the Garbage
The Elite C-90 pre-amp and M-90 power amp are no-compromise components designed to get rid of it. By keeping critical signal paths as short as possible By offering you direct CD connection. By introducing motorized volume control, separate audio and video power transformers, and unique video processing controls like noise reduction, sharpness and detail. By giving you the purest possible audio and video that digital technology has to offer.
In the words of audio critic Julian Hirsch in Stereo Review, "The C-90's signal to noise ratio is considerably better than that of any CD player... that makes the C- 90 the true peer of any digital sound source-the only pre amplifier we have tested that can make that claim7 The C-90 also cleans up your video. Because it not only controls up to six video components, its video-enhancing circuits actually improve your video image. Now, even rented videotapes take on a whole new look.
But what good is a complete A/V system without remote capabilities? The C-90's "SR" System Remote gives you complete control, plus a unique Motor-Drive Volume Control that eliminates the noise created by typical electronic volume controls.
Where the C-90 leaves off, the M-90 takes over. With 800 watts/channel into 2 ohm loads; 200 watts into 8 ohms:* and remarkably high current capability (47 amps) for low impedance driving, the M-90 delivers the kind of performance digital signals demand. And for unprecedented purity, the M-90 even includes its own volume control for direct connection to your CD player.
The Elite M-90 and C-90 working together. There's just no better way to take out the garbage.

True High Fidelity. Engineered in America. True High Fidelity was engineered in America. Surprised? Don't be.
Americans have demanding requirements for sound reproduction. That's why hundreds of thousands of Americans have chosen Acoustic Research loud speakers, car speakers, amps, turntables, cassette decks and compact disc players to be part of their premium audio component systems. AR products provide the utmost in accurate sound reproduction for the music lover.
Where the concert hall ends, AR begins. American Audio Innovation.
Acoustic Research started American Audio Innovation in 1954 with a bold, new advancement in loudspeaker technology called "Acoustic Suspension." This remarkable advancement in loudspeaker design reduced cabinet size requirements and improved fidelity. "Acoustic Suspension" enabled the production of loudspeakers small enough to come out of the basement and into the living room.
The sound improvement in a smaller cabinet was so dramatic that, today, more than 70 different companies have incorporated "Acoustic Suspension" into their loudspeaker designs.
AR. Audio Innovation Continues.
The innovation at Acoustic Research continued from that first, bold, sound engineering feat. Since then, AR has brought more advancements to the stereophonic industry... advancements like the first high fidelity bookshelf loudspeaker.
The Acoustic Blanker . The "dome tweeter." The Tetra Helix mounting plate. Magnetic fluid cooling. And the innovation continues.
Today, Teledyne Acoustic Research has combined the best in sound engineering and award winning design to bring you the newest line of AR products-AR Audio Components, the TSW Loudspeaker Series, the AR Partners and AR's impeccable car loudspeaker line.

Carver. Digital Discrimination.
BECAUSE ALL CD'S ARE NOT CREATED EQUAL, THE NEW CARVER DTL-200 MK II COMPACT DISC PLAYER IS INTRIGUINGLY DIFFERENT.
The Carver DTL-200 MK II answers the audiophile's demand for a CD Player which provides not only the greater dynamic range and richer bass expected from compact disc technology, but also the musicality, spectral balance and spatial qualities of well executed analog high fidelity recordings.
The new remote control Carver DTL-200 MK II represents the next logical evolutionary step towards marrying the awesome technology of digital play back with Bob Carver's commitment to the re-creation of the live performance. It embodies the latest digital/analog conversion circuitry with oversampling, sophisticated laser system and a wealth of operating features. And it possesses unique Carver circuitry that solves real-world sonic problems associated with commercial CDs.
TIME DOMAIN CORRECTION. The Carver DTL-200 MK II incorporates an important new computer logic innovation that monitors the incoming digital signal for imperfections and "glitches" caused in recording and production. Such errors are immune to conventional error-correction processes because they are actually data anomalies. Yet they can add overall harmonic distortion and cause audible changes in sound quality.
The DTL-200 MK II's Time Domain Correction circuit constantly performs a complex, 25-bit digital calculation on passing data. This high-speed error correction algorithm, in conjunction with a 121-pole digital filter, terminates distortion-causing high harmonics as they occur in the bit steam, The result is frequency response within 1/1000 of a dB of the original, with significant reduction of distortion to less than 0.007%.
PLUS THE DIGITAL TIME LENS. On top of this unerring ability to produce natural, real-sounding music from the CD's digital bits, the Carver DTL-200 MK II has the remarkable Digital Time Lens circuit to insure your listening enjoyment.
When Bob Carver obtained his first compact disc player, he was surprised at the sound derived from most of the compact discs he purchased. The three dimensional musical perspective which his analog system provided in lush abundance on phono discs evaporated into a flat, brittle wasteland. After extensive testing, Bob uncovered two fundamental flaws in almost all compact discs: 1) An unpleasant, harsh spectral energy balance. The overall octave-to-octave energy balance was shifted on the CD towards more midrange above 400Hz; 2) The amount of L-R signal (which carries the spatial detail of the music) on the CD was inexplicably, but substantially, reduced when compared with the amount of L-R signal found on the corresponding analog disc. The difference is obvious in these two oscilloscope photos.
A. Lissajous pattern showing spatial detail (L-R) (L+R) ratio from an LP record.
B. The same instant of music but taken from the CD version. Note the decreased (L-R) content, as shown by the narrowed trace.
Carver's circuitry corrects the ratio of L-R to L+R by performing one extra, but important mathematical operation on the signal stream that ail other CD players fail to perform. This final operation makes all the difference.
The result is a natural sound with more of the three-dimensional information that places us in the same space with performers. You won't need the Digital Time Lens on all CDs. But it is there when you need it.
In the beginning, Carver hoped, indeed he expected, that once recording artists and engineers became more experienced with CD technology fewer and fewer CDs would require the Digital Time Lens. But both laboratory and listening tests reveal that the majority of even the most recently released CDs benefit significantly from the Digital Time Lens.
PACKED WITH USEFUL FEATURES. The Carver DTL-200 MK II makes enjoying Compact Discs a simple exercise in button pushing from your favorite listening chair. You can program any combi nation of up to twelve tracks from a single CD, repeat a specific track or a whole Compact Disc for uninterrupted enjoyment.
Along with the ability to skip forward or backwards song-by-song, a touch of a key allows you to audibly review a disc backwards or forwards at many times normal speed. An A-B Specific Phrase Repeat lets you carefully analyze one section of a performance or simply provide a point of reference in a long, un-indexed symphonic movement.
All functions are displayed on an easy-to-read but subtle LCD display including programming sequence, current selection number, individual and total playing times plus indexing cues.
HEAR THE CARVER DIGITAL DIFFERENCE.
Just as all CD's are not created equal, neither are Compact Disc Players. Of all the models currently available, only the new DTL-200 MK II (and DTL-50) have the innovative and exacting Bob Carver touches that can substantially enhance your enjoyment of the digital medium.
Audition the new DTL-200 MK II today at your Carver dealer, using a variety of discs. You will be surprised at how audibly it can improve on what is already the best playback medium ever offered.
