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.
