Audio SIS Commands
Several digital signal processor (DSP) functions can be configured using SIS commands.
Commands entered via the PCS software are also displayed on the host communication
utility screen that is being used for SIS commands (for example, Extron DataViewer).
Audio Command Structure
DSP control commands are a subset of the SIS commands with a specific structure:
E
<parameter ID> <processor address> * <value> AU
}
Format example:
E
<command letter>
X%
*
X^
AU
}
The unit response to these commands begins with
Ds
.

X10# = dB level value in 0.1 increments. Use negative numbers for attenuation.
Decimal places are invalid.
Example
: -125 = -12.5 dB
