TRIM LEVEL
Source Components can have slightly different volume
levels resulting in the need to readjust the MA8900
Volume Control when switching between different
sources. The MA8900 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:
1. Select “INPUT TRIM” as indicated on the Front
Panel Information Display. Refer to figures 50, 53
and 59.
2. Adjust the Trim Level of each Input to match the
average volume level of the Input most frequently
listened to. The range of adjustment is ± 6.0dB in
half dB steps. Refer to figures 60 and 61.
After approximately 5 seconds the Information
Display returns to indicate the Source Selection and
Volume Level.
PHONO ADJUSTMENTS

TRIM SELECT FUNCTION becomes available for
adjustment. Perform the following steps to make the
Phono Trim Adjustment:
1. Select the MC Phono Source Input.
2. Select TRIM “PHONO RESISTANCE, 400Ω” as
indicated on the Front Panel Information Display.
Refer to figure 62.

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.
