Command/response table for SIS commands (continued)
Command
Audio input gain and attenuation
N The set gain (G) and set attenuation (g) commands are case sensitive. The increment, decrement, and read commands are not case sensitive.
Set input audio gain to
+dB value
Example:
Set input audio
attenuation to -dB value
Increment gain
Example:
Decrement gain
Example:
Read input gain
X!
