28 OPERATION

Normal output level adjustment for the 
AVR 2500 is established using the test tone, as
outlined on pages 21 and 22. 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. Additionally,
the output level for the subwoofer and those for
the Stereo and VMAx modes can only be adjust-
ed using this procedure.

To adjust the output levels using program materi-
al, first select the surround mode for which you
want to trim the speakers (see NOTE below) by
selecting the appropriate input, associated with
the desired surround mode, start your program
material source and set the reference volume for
the front left and front right channels using the
Volume Control (

".

Once the reference level has been set, press the
Channel Select button 

CÛ and note that

FL LEVEL

will appear in the Main

Information Display M for five seconds. To
change the level, first press the Set button 

E

Ó , and then use the Selector buttons 5 or
the 

⁄

¤

buttons 

C to raise or lower the

level. DO NOT use the volume control, as this
will alter the reference setting.

Once the change has been made, press the Set
button 

E Ó and then press the Selector but-

tons 5 or the 

⁄

¤

buttons 

C to select the

next output channel location that you wish to
adjust. To adjust the subwoofer level, press the
Selector buttons 5 or the 

⁄

/

¤

buttons 

C

until SW LEVEL appears in the Main
Information Display M (only available if the
subwoofer was selected during the speaker con-
figuration, see page 18).

Press the Set button 

E Ó when the name of

the desired channel appears in the Main
Information Display M and on-screen display,
and follow the instructions shown above to
adjust the level.

Repeat the procedure as needed until all chan-
nels requiring adjustment have been set. When
all adjustments have been made press the Set
button

E Ó twice, the AVR 2500 will return

to normal operation.

NOTE: The output levels may be separately
trimmed for each digital and analog surround
mode. If you wish to have different trim levels for a
specific mode, select that mode and then follow the
instructions in the steps shown above.

Changing the levels by the trim adjustment as
described above will automatically change the
level settings shown during the Output Level
Adjustment (see page 21) correspondingly (and

vice versa) and will remain in the AVR 2500´s
memory system, even when the unit is turned off.
With Stereo and Vmax modes the adjustment
procedure described above is the only way to
trim the output level (e.g. to match the Vmax
level with other modes).

The AVR 2500’s front panel Main Information
Display Ú is set at a default brightness level
that is sufficient for viewing in a normally lit
room. However, in some home theater installa-
tions, you may wish to occasionally lower the
brightness of the display, or turn it off completely.

The display brightness may be changed by press-
ing and holding the Set button Ó on the front
for three seconds until the message in the Main
Information Display M reads V F D
F U L L

. Within five seconds, press the front

panel

buttons 5 until the desired brightness

display level is shown. At that point, press the
Set button Ó again to enter the setting.

This product is equipped with a memory backup
system that preserves tuner presets and system
configuration information if the unit is turned off
completely, accidentally unplugged or subjected
to a power outage. This memory will last for
approximately two weeks, after which time all
information must be reentered.
