Operation
6. NOTE: The design of some early DVD
players is such that you may occasionally
hear a click or pop when the player starts
after being paused or after a Search mode
is used. This is a function of the format
and does not indicate any problem with
your AVR55.
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
AC-3/PCM Optical or Coaxial inputs
¶fon the rear panel, using whichever
input is not occupied by an AC-3 source
such as a DVD player.
To play a PCM source, first select the
desired input using the
Input
Selectors
)$%^*de.
Next, choose either an Optical or Coaxial
digital source using the
Digital Input
Selector
hı. Finally, select any
Surround mode other than Dolby Digital.
Tuner Operation
The AVR55’s tuner is capable of tuning
AM, FM and FM Stereo broadcast stations.
Stations may be tuned manually, or they
may be stored as favorite station presets
and recalled from a 30 position memory.

When the
AUTO indicator is illuminated
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 manually tune stations, press the
right side of the Tune button

to tune
a station with a higher frequency, or the
left side to tune a station with a lower fre-
quency. When the

illuminates, the station is properly tuned
and should be heard with clarity. To
automatically search for the next station
with acceptable signal strength, press
and hold the
Tune button

until the
AUTO indicator lights. Release it and the
tuner will stop when it finds a station.
When a station is weak, audio quality
will be improved by pressing the FM

NOTE: When the FM reception of a
station is weak, audio quality will be
increased by switching to mono mode
by pressing the Tuning Mode button

Preset Tuning
Up to 30 stations may be stored in the
