FEATURES

In conventional analog recording systems, the quality of sound
reproduction depends upon the properties of magnetic tape and
heads. Even with the latest metal tape it is virtually impossible to
bypass the inherent limitations oI conventional analog recording,
including its limited dynamic range and frequency response and
its associated distortion.

The Pulse Code Modulation (PCM) system ushers in a new era of
sound reproduction and otters performance and Iidetity far
superior to analog systems. In the PCM system, sound levels are
converted to a series of binary codes. This information is recorded
as digital pulses of equal amplitude. In playback, all that has to be
done is to discriminate between the presence and absence 01 a
pulse. The quality of recording and playback is thus not dependent
on the characteristics of tape and heads.

The PCM-701ES is the latest and most sophisticated Sony PCM
digital audio processor for general audio use. it offers its own built-
in power source for convenient operation and the host 01 other
features outlined below for the ultimate in audio listening pleasure.
The PCM- 701 ES gives you stereo sound reproduction with a wide
dynamic range, minimal distortion low wow and flutter (even lower
than the measurable limit), and a flat frequency response. Listen-
ing to digital audio sound tapes on your PCM-701ES is just like be-
ing in a concert hall.

Compact PCM digital audio processor with modern component
design

While several hundred ICs are employed In the digital processing
Circmtry ol conventional digital audio processors. 3 new LSIs help
make the PCM-701ES as compact and modern In design as your
other audio equipment, The unit also incorporates A/D (analog-to-
digital) and DIA (digital-toanalog) converters which are newly
developed monolithics. All function to make the PCM~701ES unex-
celled in performance and reliability.

Resolution selector for recording and playback with wider dynamic
range and less distortion

The PCM-701ES was developed In accordance with the technical
specifications of the Electronic Industries Association of Japan
(ElAJ). which has adopted the 14-bit linear quantization format. In
addition. the unit has the capability of recording and playback in
accordance With the 16bit linear quantization format which ollers
a Wider dynamic range and less distortion than the i4- bit lormat.
The 14-bit and 16 bit lormals can be selected with the REC
RESOLUTION (record resolution) selector

Easy tracking adjustment tor tracking ol video heads

The R (right) channel of the peak program meters converts to a
tracking meter allowing lor easy and correct tracking adjustment
of the Video heads.

PB MUTING (playback muting) button provides option at con-
tinuous listening

The PCMJOiES leatures a playback muting system that gives you
the option ol having dropouts cut out automatically when the
muting circuit is switched on Or. you can simply set the button to
OFF for continuous, uninterrupted listening. Muting also functions
at double and triple tape speed,

Extremely accurate error-detection and correction circuits
These keep dropout errors from effecting the quality of sound
reproduction.

Convenient record muting lunction

A highly convenient record muting function allows you to create
blank spacmg between selections to cut out unwanted talk and
commercials.

COPY OUT jack tor perlect tape copies

Multi-generalion, digital-to-digital tape copy can be performed us-
ing the COPY OUT jack on the back of the unit with absolutely no
deterioration in signal quality.

Bright, easytoread peak program meters
Fluoresent peak program meters provide two types of sound level
indication for precision setting of recording and playback levels.

Stable power supply
Two separate CliCUIIS. one for the digital circuitry and one for the
analog circuitry, assure stable power supply.

Separate MONITOR OUTPUT jack allows connection with the Sony
Proteel series and other video monitors

Thers's no need to disconnect your digtal audio processor to
monitor video tapes and T.V. The MONITOR OUTPUT jack on the
back of the PCM-701ES allows transmission of video signals
whether the PCM unit is switched on or off.
