2 Channel Sub
The C45 has both Balanced and Unbalanced SUBwoofer
Outputs. If either one of the 6 Channel Inputs are selected,
the C45 Amplifies the signal at the SUBwoofer Input and
makes it available at the SUBwoofer Output. When a 2
Channel Input is selected the C45 is also capable of provid-
ing signal at the SUBwoofer Outputs by performing the fol-
lowing steps: Refer to figure 3 on page 15.
Note: If the C45 is to be used as a two channel only
preamp, one of the SUBwoofer Outputs may be
connected to an additional power amplifier and
Loudspeaker to provide a “center fill channel”.
The SUBwoofer Outputs are Full Range Audio
Frequency Outputs and the signal present is a sum
of both Left and Right Channels.
