Additional description
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)
•
Pre-mixer (gain and mute)
•
Virtual Return (gain and mute)
•
Output (attenuation and mute)
•
Aux Input (gain, mute, and source)
•
Mix-points (gain and mute)
•
Post-mixer (gain only)
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
-18
dB to
+80
dB in
0.1
dB increments when the source is set to analog.
The mic/line input gain range is
-18
dB to
+24
dB in
0.1
dB increments when the source is set to a digital input (for more on changing the input
source (see the
DSP Configurator Help File
for more information).
•
The pre-mixer gain and virtual return gain range is
-100
dB to
+12
dB in
0.1
dB increments.
•
The post-mixer trim gain range is
-12
dB to
+12
dB in
0.1
dB increments. Post mixer trim cannot be muted.
•
The output attenuation gain range is
-100
dB to
0
dB in
0.1
dB increments.
•
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

G
parameter when setting or
reading input gain level (for more on changing the input source, see the
