Command and Response Tables for DSP SIS Commands
Many digital signal processor (DSP) functions; gain, mute, group masters, and a protected
configuration 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 to understanding
the commands. Figure 61 shows specific DSP functions available using SIS commands.
NOTE: The entire signal flow is described in more detail in the DSPConfigurator
program section (see Windows-based Program Control on page15).
