PCM Audio Playback
PCM (Pulse Code Modulation) is the
non-compressed digital audio system
used for compact discs and non-AC-3
laser discs. The digital circuits in the
AVR55 are capable of high-quality digital-
to-analog decoding, and they may be
connected directly to the digital audio
output of your CD or LV player.
Connections should be made to the
or
AC-3/PCM Optical
Coaxial
on the rear panel, using whichever
¶ f
input is not occupied by an AC-3 source
such as a DVD player.
IMPORTANT NOTE: PCM Audio play-
back is possible ONLY when the CD input
is selected. If you wish to use the AVR55
to decode the PCM audio track from a
Laser Disc player, you must first select the
CD input.
