maintenance or repair. These fundamental
elements are incorporated in the McIntosh
Compact Disc Player. Yet, additional re-
quirements were demanded for long term
superior listening performance.

Lets look at some of the electronic and re-
production requirements ,for superior sound.
You, a critical listener, demand noise free,
distortion free and restriction free music
reproduction. The digital disc holds great
promise for the satisfaction of these
demands. in spite of the latent possibilities,
there has been some consumer criticism of
"digital sound. Here are some ideas of what
the McIntosh Compact Disc Player does to pro-

Playback sound quality that has the ability
to recapture the true studio sound. Tech-

niques like Double Digital Filtering and
special error correction makes the McIntosh
player audiblry better in sound quality. You
will hear it.

The task of the compact disc player is to
decode the encoded data, use it to control
drive motor speed and laser spot tracking,
correct errors, derive the sound information,
and present it in a way to satisfy the most
critical ears, 'your'earSTPlclntosh'has the best
thought-out design which will bring you the
highest satisfaction.

In the Compact Disc system, the original
sound is sampled, measured and quantized
(converted to binary numbers). It thus
becomes a pulse code modulated (PCM) signal
representing the original sound, but before
being encoded on disc, it is specially pro-

playback easy and convenient. Control and
display information is added to provide fast
access and programming possible.

Special Eight'to-Fourteen modulation (EFM)
ensures that a maximum of sound informa-
tion can be packed into the disc which re-
quires a minimum of error correction, pro-
vides vital timing information, and improves
trackability. Sophisticated Cross-Interleaved
