Input Level Adjustment
Source Components can have slightly different volume
levels resulting in the need to readjust the C48 Volume
Control when switching between different sources.
The C48 allows the adjustment of levels for each of
the Source Inputs for the same relative volume. The
CD and SERVER Inputs are used in the following
example.
Note: The range of adjustment is ± 6dB. The signal Level
present at the RECORD OUT Jacks is unaffected
by any changes in the Setup Level adjustment. The
level adjustments made are retained in permanent
memory. They can be changed during operation
of the C48 by performing a Trim Level Procedure,
refer to page 19 for additional information.
1. Rotate the INPUT Control to select the CD Input
and adjust the VOLUME Control to the desired
listening level.
2. Press and hold the EQ BYPASS/SETUP Push-
button until the Setup Mode is active. Then press
the OUTPUT 2 / MENU ► Push-button until the
Setup Menu item “LEVEL: CD 0.0dB” appears
on the Front Panel Information Display. Refer to
figure 9.
Note: The CD Input is serving as a reference level
or choose another source frequently listened
to. The Input Source should be set to a refer-
ence Level (Trim) of 0.0dB.
3. Rotate the INPUT Control until “LEVEL: SRVR
0.0dB” appears on the Front Panel Information
Display. If necessary, rotate the VOLUME/AD-
JUST Control to obtain the same volume level
