Trim Level Adjustment
Source Components can have slightly different volume
levels resulting in the need to readjust the C2300 Volume
Control when switching between different sources. The
C2300 allows the adjustment of levels for each of the
Source Inputs for the same relative volume. The Tuner and
CD Inputs are used in the following example.
Note: The range of adjustment is ± 6dB. The Tape/Record
Output 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 Tuner Input
Volume Level can serve as a reference or choose an-
other 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 Tuner Input
and adjust the VOLUME Control to the desired listen-
ing level.
