Command/Response Tables for DSP SIS Commands

Many digital signal processor (DSP) functions (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 (X/) tend to be more complex. Also, a comprehensive understanding of the audio signal flow is helpful in understanding the commands.

The following figure shows the specific DSP processors available for SIS commands.

NOTE: The entire signal flow is described in more detail in the

“DSP Processing and Signal Flow”section.

The DSP Configurator program window consists of an input signal processor chain, the mixer matrix, and an output signal processing chain. The following five processors can be controlled using the DSP SIS commands:

ALine input gain control — Provides level adjustment, mute and polarity.

BLine input pre-mixer gain — Provides basic level adjustment after the input audio processing chain and prior to the mix-point.

CMix-points— Provide level adjustment and signal routing from the inputs to the outputs.

DOutput trim control — Provides level adjustment after the line input audio processing.

EOutput volume control — Provides volume control of the variable output, mute, and polarity.
