Re-Title Inputs
The C45 has nine Audio Inputs, which include the optional
TM1 AM/FM Tuner Module. These inputs already have
assigned titles that will allow for immediate hookup, opera-
tion and enjoyment. In addition, there are two 6 channel in-
puts and a balanced input that are assignable as replacement
for each one of the inputs.
If these starting assignments do not match up with com-
ponents in your system, they may be reassigned from the
default settings. The following example will illustrate how
to rename the AUX Input to PHONO. When the Input Se-
lector is rotated to select what was originally the AUX In-
put, PHONO will now appear on the Front Panel Alphanu-
meric Display. Refer to figure 3 on page 15.
Notes: 1. Unused Inputs may be switched Off so they will not
appear when rotating through the input source
choices using the Input Selector and also will not be
available when using the Remote Control or Keypad.
Refer to figure 12.
2. The New Input Titles that are available for all the
Inputs include TAPE 2, LV, TV, and VCR2. The AUX
Input (INPUT 1) Titles also includes PHONO.
1. Press the SETUP Push-button to access the Setup
Mode.
2. Press the TONE BYPASS (Menu) Push-button until
“INPUT _ ___” appears on the Front Panel Alphanu-
meric Display.

Level Adjustment
Various Source Components can have slightly different vol-
ume levels. This could result in the constant need to readjust
the C45 Volume Control when switching between different
Input Sources. The Level Input Trim Feature on the C45
allows the adjustment of levels for each of the Source In-
puts, so that they have the same relative volume. The Tuner
and CD Inputs are used in the following example. Refer to
figure 3 on page 15.
Notes: The possible range of adjustment in volume level is
± 6dB. The Tape/Record Output Levels are unaffected
by any changes in the Level Trim Settings. Any LEVEL
Trim adjustments made are retained in permanent
memory and can be changed only by performing a new
Level Trim Procedure. The Tuner Input Volume Level
can serve as a reference or choose another Input
Source that is frequently listened to as the reference.
The reference Input Source should be set to a Level of
00.
1. Rotate the INPUT Control to select the Tuner Input and
adjust the VOLUME Control to the desired listening
level.
2. Press the SETUP Push-button to access the Setup
Mode.
3. The Front Panel Alphanumeric Display will change and
the Red LED above the SETUP Push-button will be il-
luminated.
4. Press the TONE BYPASS (Menu) Push-button until
“LEVEL 0.0___” appears on the Front Panel Alphanu-
meric Display.
5. Rotate the INPUT Counter-clockwise until the display
indicates “LEVEL 0.0 TUN”. Refer to figure 15 on the
