Command/Response Tables for DSP SIS Commands

Digital signal processor (DSP) functions, gain and mute, can be controlled using SIS
commands. These commands follow the same general rules as basic SIS commands, but
the variables (
audio signal flow is helpful to understanding the commands. The following diagram shows
the specific DSP processors available for SIS commands.
NOTE: The entire signal flow is described in more detail in the section, (see
Figure 39.
The DSP Configurator program window addressable commands consist of an input signal
gain control, the mixer matrix, and output volume and gain controls.

DSP control commands are an extension to SIS commands. They differ only in their data
string and the requirement to send each command with an "AU" suffix.

Mix-points — Mutes input signals to outputs.
Output gain control — The stereo fixed output provides level adjustment and mute.
