Akai CD-55 - Digital Connections

Digital connections
This CD player is equipped with a D/A (Digital to Analog) con-
verter" (used for converting the digital PCM signal to conven-
tional left and right channel audio signals). An OPTICAL termi-
nal and COAXIAL jack for digital signal output are also
included for digital audio signal output. These connections
can be used if you wish to add a higher grade D/A converter or
a digital integrated amplifier which is equipped with aD/Acon-
verter.

Note
@ Asregular connection cords are not designed to handle the
high frequencies that are part of the PCM signals, they are
not recommended for digital connections.
@ Video connection cords or cords designed for digital con-
nection are recommended.
@ Because the digital PCM signal is a composite signal made
up of left and right channel signais, a single connection
cable is used for connections.
@ The Digital to Analog Converter (i.e. D/A converter or DAC)
unit converts digital PCM signals such as the playback sig-
nals of a compact disc to conventional left and right audio
stereo signals.
@ Disconnect the analog audio connection cord from the
VARIABLE or FIX LINE OUT jacks for good sound repro-
duction when using the digital connections.
