Dsp Sis Commands - Extron electronics DMP 128 Plus User Manual

DSP SIS Commands

Many digital signal processor (DSP) functions such as gain, mute, and group masters can
be controlled using SIS commands. These commands follow the same general rules as
basic SIS commands but the variables can be more complex. Also, 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)
Pre-mixer (gain and mute)
•
