matrix_gain
Matrix Crosspoint Gain
Description
This parameter sets the gain (in dB) for the specified crosspoint in the matrix
mixer.
Examples
set matrix_balance
"Program Audio" "HDX
Line Mix Out" 1
val matrix_balance
"Program Audio" "HDX
Line Mix Out" 1.000
Sends only the right channel of the stereo program audio
"Program Audio" source to both stereo audio outputs
"HDX Line Mix Out"
set matrix_balance
"Program Audio"
"Amplifier" 0
val matrix_balance
"Program Audio"
"Amplifier" 0.000
Sets the balance so that left is sent to left and right is sent
to right on the stereo virtual channel input and output.
This ensures the stereo program audio "Program Audio"
left and right channels are sent to the stereo audio output
"Amplifier" left and right channels, respectively.
