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
