Operation

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 

inputs

¶ f

on the rear panel, using whichever

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.

The AVR55’s tuner is capable of tuning
AM, FM and FM Stereo broadcast sta-
tions. Stations may be tuned manually,
or they may be stored as favorite station
presets and recalled from a 30 position
memory.

in the main information display the
tuner will only stop at those stations that
have a strong enough signal to be
received with acceptable quality.

If the 

AUTO

indicator is NOT illumin-

ated, the tuner is in a manual mode and
will stop at each frequency increment in
the selected band.

4. To select stations from the front panel
press the 

button

cause the tuner to search for the next
highest or lowest frequency station that
has an acceptable signal. When tuning
FM stations in the auto mode, the tuner
will only select Stereo stations. To tune 
to the next station, press the button
again. If the 

AUTO
