Source Components can have slightly different volume
levels resulting in the need to readjust the MA352

sources. The MA352 allows the adjustment of levels
for each of the Source Inputs for the same relative
volume. To adjust the Trim Level for the currently
selected Input Source perform the following steps:
1. Select “INPUT TRIM, 0.0dB” as indicated on the
Front Panel Information Display. Refer to figure
65.
