You Don’t Become A Digital Audio Expert Overnight.

Most of the companies now introducing digital audio players were just recently introduced to digital audio themselves.

Such is not the case with Mitsubishi.

We've been at the leading edge of digital audio research since the early 70's, when our involvement in satellite communication equipment and computers showed that pulse-coded modulation would bring about a revolution in recorded music.

Our technological focus back then was on professional recorders, which could immediately apply the superiority of digital sound to the recording of conventional analog records.

The 32-channel X-800 model shown (rear) is the most sophisticated audio recorder ever engineered. Taking over where the last generation of analog recorders left off.

And now the digital sound revolution has come full circle, from our pioneering work in digital tape recording to our new digital disc player. Taking over where the last generation of analog record players left off.

INTRODUCING THE MITSUBISHI DIGITAL AUDIO DISC PLAYER.

Analog record players attempt, with varying success, to play back a mechanical, physical likeness of the music's continuously changing waveforms in grooves on the record.

The Mitsubishi DP-101 digital disc player does the infinitely more exacting job of reading music that has been digitally encoded in microscopic "pits" on a Compact Disc.

The code represents over 44,000 measurements a second of the musical waveforms. The pits, and their dimensions, represent the digital data.

--------The beam from the laser diode (A) is reflected off beam splitter (B) and focused through objective lens (C) to read the pit (D) on the disc, and returns with the encoded music information through the lens and beam splitter into the photo-detectors (E).

The music encoded in the pits is read, not by a mechanical stylus, but by a laser beam. This allows for a reproduction accuracy that the stylus, restricted by the laws of physics, can’t match.

It's this esoteric laser technology that is the heart of the system, and Mitsubishi's long experience in semiconductor lasers for fiber-optical communications enables us to maximize performance of this key element to our own rigorous standards.

HEAR NOTHING. AND EVERYTHING.

Nothing bad. No noise, no wow, no flutter, no rumble. No pops, clicks or surface noise.

Everything good. From complete silence, the music emerges in its full power and range, every detail etched in great relief. Music utterly uncompromised by the undesirable.

Nothing ever sounded so good before.

------- Better sound is easy to see.

As if to validate the evidence of your ears, the specs are spectacular.

Distortion, as shown, 0.008% (compared to analog's 0.5 to 1.5%). Dynamic range, 90 dB (compared to 60-70 dB). Channel separation 80 to 90 dB (clearly separate from analog's 20-50). And an exquisitely flat frequency response within 0.5 dB from 2Hz to 20kHz.

Yet this astonishingly complex machine is easier to operate than an audio tape cassette player.

It features a full-function remote control unit. And extensive programming controls enable you to play any part of the disc, in any sequence you choose. No other digital player we know of can offer you more flexibility.

Nor can they offer you the unique feature located just below those programming controls. One that insures the excellence of all that lies within.

It's stamped into the metal.

The name Mitsubishi.
