Matrix Mixer
Once a signal has been routed to the mix point of an output channel strip, it enters the matrix mixer
stage of the gain structure. Double-click on any mix block to open the Matrix Mixer processor window,
which displays a pane for each output channel strip. When crossovers are placed over multiple output
channels, the mixer panes for those channels will combine to reflect that configuration. Use this
window to adjust the polarity and relative levels of all inputs routed to the selected output channel.
After the matrix mixer, the signal passes sequentially through the processor slots on the designated
output strip. At the end of the channel strip, the signal arrives at the output gain block.
Output Gain
This is the final stage of gain control in the System Processor. Double-click on any output gain block to
open the Output Gain processor window. It acts as a post-processing trim; providing scaling, gain,
polarity control, and an optional 20dB pad for each channel. This window also allows you to designate
custom names for your output channel strips. After the output gain processor, the signal passes through
the D/A converter, to the audio output.
Muting Channels
There are several ways to mute the input and output channels of the System Processor. Muted
channels are flagged in the signal flow diagram, as illustrated in the following table.

Muting All Inputs or Outputs
§ Click either the Mute All Inputs or Mute All Outputs control located at the bottom of the
main window.
§ Select either the [Processor>Mute All Inputs] or the [Processor>Mute All Outputs]
menu option.
§ Power off the device to automatically mute all outputs.
Muting Individual Channels
1. Open the Input Gain, Matrix Mixer, or Output Gain window by double-clicking the appropriate gain
or mix block.
2. Click the mute button for the appropriate channel.
3. The block will be flagged with a red "M" to indicate that it is muted.
Labeling Inputs and Outputs
Inputs and outputs are untitled when you create a new scene file, but they are easily changed using the
Input Gain and/or Output Gain windows. Channel labels are saved along with the preset or scene file, so
you can customize label inputs and outputs for every system configuration.
To change a channel label:
1. Double-click on the channel’s gain block.
2. In the processor window, locate the channel’s label box.
3. Click and drag over the text to highlight it.
4. Type in a new label of no more than fifteen characters.
5. Apply the changes by clicking on another control or closing the window.
