Output Level Trim Adjustment
Normal output level adjustment for the
AVR55 is established using the Test Tone,
as outlined on page 19. In some cases,
however, it may be desirable to adjust the
output levels using program material
such as a test disc, or a selection you are
familiar with.
To adjust the output levels using pro-
gram material, first set the reference
volume for the front left/right channels
using the
Volume Control
˘ n
. If
you wish to vary the difference between
the left and right channels, use the
Balance Control
Ù
.
To change the level for the channels you
wish to adjust use the appropriate front
panel level adjust control for the
Subwoofer
,
Center
or
Surround
channels ¸ ˝ 34 .
Memory Backup
This product is equipped with a memory
backup system that preserves tuner pre-
sets and system configuration informa-
tion if the unit is accidentally unplugged
or subject to a power outage. This mem-
ory will last for approximately one week,
after which time all information must be
re-entered.
Processor Reset
In the rare case where the unit’s opera-
tion or the displays seem abnormal, the
cause may involve the erratic operation of
the system’s memory or microprocessor.
To correct this problem, first unplug the
unit from the AC wall outlet and wait at
least three minutes. After the pause,
reconnect the AC power cord and check
the unit’s operation. If the system still
malfunctions, a system reset may clear
the problem.
If the system is still operating incorrectly,
there may have been an electrostatic
discharge or severe AC line interference
that has corrupted the memory or
microprocessor.
If a reset does not solve the problem,
consult an authorized Harman Kardon
service depot.
