output volume (V) commands available in the basic SIS commands.
•
The command format is the same, regardless of the control or mix-point that is to be set; the acceptable adjustment
range varies depending on the control or mix-point:
The program audio input (pre-matrix) trim range is -12 dB to +12 dB, in 0.1 dB increments.
The mic/line input gain range is 0 dB to 80 dB, in 1.0 dB increments.
The post-matrix level trim is -12 dB to +12 dB, in 0.1 dB increments.
The mic mix-points (with their associated mixing controls) range is -35 dB to +25 dB, in 0.1 dB increments.
•
All responses are shown with the matrix switcher in Verbose mode 2 or 3.
