Command and Response Table for DSP SIS Commands
Command
Many digital signal processor (DSP) functions such as gain, mute, and group masters can be controlled using SIS commands. An
understanding of the audio signal flow is helpful for using audio DSP SIS commands. The following gain blocks are addressable via SIS
commands:
•
Mic/Line Input (gain and mute)
•
Aux Input (gain, mute, and source)
Audio Level Control
NOTES:
The command format is the same regardless of the control point, but the acceptable gain range varies depending on the control point.
•
The mic/line input gain range is
The mic/line input gain range is
source (see the DSP Configurator Help File for more information).
•
The pre-mixer gain and virtual return gain range is
•
The post-mixer trim gain range is
•
The output attenuation gain range is
•
All responses are shown with the DMP 64 in Verbose mode 2 or 3.

NOTE:
If the input source is set to a digital input (AT or Expansion input), use the H parameter instead of the G parameter when setting or
reading input gain level (for more on changing the input source, see the DSP Configurator Help File for more information).
