Adjust the BASS and TREBLE controls to suit your listen-
ing preferences. The Bass or Treble intensity can be in-
creased with clockwise rotation and decreased with counter-
clockwise rotation. All tone control circuit elements are re-
moved from the signal path when the controls are in the
center or flat position.
Note: The Bass and Treble controls affect the Front Left and
Right Channels only.
6 Channel Mode
When a 6 Channel Input has been assigned to one of the
eight inputs and that Input is selected, the C45 will auto-
matically switch to the 6 Channel Mode and the red Led
above the 6 CH MODE Push-button will illuminate. If the
6CH MODE Push-button is pressed at that time the C45
will revert back to the 2 Channel Mode and the Audio Sig-
nal present at that Input’s Left and Right 2 Channel jacks
will be heard instead.
Note: The C45 will retain the choice of 2 Channel Mode until
either the 6CH MODE Push-button is pressed when the
C45 is on that six channel Input or the C45 is switched
Off and then On. If the optional TM1 Tuner Module is
installed into the C45, the 6CH MODE (ENTER) Push-
button is also used to enter AM/FM Radio Station(s)
into Preset Memory. Refer to page 31 for additional
information.
Trim and Trim Level
When the C45 is in the 2 Channel Mode and the 2CH SUB
Mode is set to ON in the Setup Mode, the TRIM and TRIM
LEVEL Push-buttons provide the means for adjusting the
Subwoofer Volume Level separately from the main left and
right channels. Refer to page 19 for changing the 2CH SUB
Mode. If an Input is assigned as a 6 Channel Input, there
are Volume Trim Adjustments for the Center, Subwoofer
and Surround Channels.
The Trim Adjustments can be accomplished from either
the Front Panel Controls or with the supplied Remote Con-
trol. There is a ± 12dB range of volume adjustment for each
of the Trim Selections.
The C45 has separate Subwoofer Trim Levels for both
the 2CH and 6CH Modes of operation. It will also reset the
Center, Subwoofer and Surround Trim Levels to 0dB when
the C45 is turned Off. The Front Panel Alphanumeric Dis-
play indicates the Trim Mode Selected and Trim Levels. Re-
fer to figures 40 and 41.
