Trim Level Adjustment
Source Components can have slightly different volume
levels resulting in the need to readjust the MA6600
Volume Control when switching between different
sources. The MA6600 allows the adjustment of levels
for each of the Source Inputs for the same relative
volume. The CD1 and SERVER Inputs are used in the
following example.
Note: The range of adjustment is ± 6dB. The REC Out-
put Levels are unaffected by any changes in the
Level Trim Settings. The Trim adjustments made
are retained in permanent memory. They can be
changed by performing a new Trim Procedure.
The CD1 Input Volume Level can serve as a refer-
ence or choose another source frequently listened
to. The reference Input Source should be set to a
Trim Level of 00.
1. Rotate the INPUT Control to select the CD1 Input
and adjust the VOLUME Control to the desired
listening level.
