TRIM LEVEL
Source Components can have slightly different volume
levels resulting in the need to readjust the MA9000
Volume Control when switching between different
sources. The MA9000 allows the adjustment of levels
for each Source, ensuring the same relative volume. To
adjust the Trim Level for the currently selected Input
Source perform the following steps:
BALANCE
Listening balance varies with different program sourc-
es, room acoustics and listening positions relative to
the Loudspeakers. Use the Balance (Trim Function) as
needed to achieve approximately equal listening vol-
ume levels in each Loudspeaker. To adjust the Balance
perform the following:
1. Press the TRIM Push-button repeatedly on the Re-
mote Control until “L BALANCE R, || ” appears
on the Front Panel Display. Refer to figure 54.
Note: The Front Panel INPUT/Trim Control may also
be used.
2. Rotate the VOLUME/Adjust Control or press the
LEVEL UP / DOWN Push-buttons on the Remote
Control to emphasize the Right Channel (refer to
figure 55) or the Left Channel (refer to figure 56).
The Front Panel Display indicates the relative Balance
changes. After approximately 5 seconds, the Display
returns to indicate the Source Selection and Volume
Level. To verify the Balance setting without changing
it, use the TRIM Push-button and select Balance.
