Set up the Outputs

NOTE:  Changes made to outputs are in real time.

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.
