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) • Virtual Return (gain and mute)
• Aux Input (gain, mute, and source) • Post-mixer (gain only)
• Pre-mixer (gain and mute) • Output (attenuation and mute)
