Mixer
The CXD amplifiers are equipped with an internal mixer that allows you to
adjust the signals from each input to each of the four outputs. Figure 26 is a
diagram of the Mixer for Output Channel A.
• The default setting for the Input Gain is 0.0 dB, and is set in the
INPUTS section.
• Each output channel has four inputs, each controlled by a Mixer Gain.
• The Input Gain and Mixer Gain are cumulative. For example, if you set the
Input Gain to +2.0 dB, and the Mixer Gain to -5.0 dB, the resulting output
is -3.0 dB
As a default one channel is mixed to each output: 1 - A, 2 - B, 3 - C, 4 - D, all
other input channels are set to -100. Adjusting an Input Gain changes that
channel's input to the mixers of all channels. Changing a Mixer Gain affects only
that input for the selected output channel.
