Operation

• To program the AVR55 for automatic
turn off, press the 

button

on

the remote. Each press of the button will
increase the time before shut down in the
following sequence:

The sleep time will be displayed on the
right side of the 

F

, and it will count down until the time

has elapsed.

When the programmed time has elapsed
the unit will automatically turn off. Note
that the front panel display will dim to
one half brightness when the Sleep func-
tion is programmed. To cancel the Sleep
function, press the 

button

until the information display returns to
normal brightness and the Sleep
indicator numbers disappear.

The AVR55 is capable of automatic
operation that turns it on and off in
response to the operation of an audio
source such as the TV. This eliminates
the need to manually turn on the AVR55
with a separate remote command. While
this feature is most commonly used with
TV audio, it may be used with any audio
source. To use the TV Auto-On feature
follow these steps:

1. Connect the audio source that will be
used to trigger the Auto-On feature to the

¤

.

2. Activate the feature by pressing and
holding the 

button 

$ e

on the front panel or remote until the
words 

AUTO-OFF

appear in the

F

.

3. Release the button, and then press it
again within 2.5 seconds until the dis-
play changes to read 

AUTO-ON

and

then release the button.

4. The TV Auto-On feature is now engaged.
Whenever an audio source is present at the
TV input and the AVR55 is in the Standby
mode the unit will automatically turn on
and switch to the TV input.

5. Unless another input source is selected,
the unit will automatically return to the
Standby mode approximately five min-
utes after the audio source connected to
the TV input is turned off.

NOTE: Remember that when the TV Auto
feature is engaged the AVR55 will turn off
whenever the TV input has been selected
and the source feeding that input is not
active. To disable this feature follow steps
2 and 3 above, but toggle the buttons so
that the words 

AUTO-OFF

appear in 

the 

F

.

One of the most important features of 
the AVR55 is its ability to reproduce a full
multichannel surround soundfield from
Dolby Digital sources, analog matrix 
surround encoded programs, and stan-
dard stereo programs. In all a total of
seven listening modes are available on
the AVR55.

Selection of a surround mode is based 
on personal taste, as well as the type of
program source material being used. 
For example, motion pictures bearing
the logo of one of the major surround
encoding processes, such as Dolby
Surround, DTS

†

Stereo or UltraStereo

††

may be played in either the Dolby
Digital, Dolby Pro Logic or Movie
Surround depending on the source
material. TV or radio broadcasts of
programs in surround, but not originally

produced as theatrical motion pictures
should normally be played back in Dolby
Pro Logic or one of the other analog
surround modes.

NOTE: Once a program has been
encoded with surround information, it
retains the surround matrix as long as
the program is broadcast in stereo. Thus,
movies with surround sound will carry
surround information when they are
broadcast via conventional TV stations,
cable, pay TV and satellite transmission.
In addition, a growing number of made-
for-television programs, sports broad-
casts, radio dramas and music CDs are
also recorded in surround sound. You
may obtain a list of these programs and
discs from the Dolby Laboratories web
site at www.dolby.com

Surround modes for conventional analog
audio inputs are selected by pressing the

button 

Ò

on the

front panel or the 

and 

buttons 

y `

on the remote. As

described above, when a “Surround
Sound” logo is associated with the pro-
gram you are listening to, it is always
best to start with Dolby Pro Logic, or
Dolby 3-Stereo when there are no sur-
round speakers. However, you may wish
to experiment with the Theater, Hall,
Church or Stadium modes to see if you
find that sound more pleasing.
Remember, you can’t break anything by
trying a different surround mode.

When a program is not listed as carrying
intentional surround information, you
will find that the Pro Logic or Dolby 3-
Stereo often deliver enveloping surround
presentations through the use of the
natural information present in all stereo
recordings. However, for stereo, but non-
surround programs, we suggest that you
try one of the other analog surround
modes to see which one is most suitable.
