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:

Level values use a 10x multiplier system to set gain via SIS
command. For example, if the desired gain value is +10.3 dB,
the SIS value would be
is -8.2 dB, the SIS value would be
-12.0 dB to +12.0 dB, (-120 to 120) in 0.1 dB increments.
-18.0 dB to +80 dB, (-180 to 800) in 0.1 dB increments.
-100.0 dB to +12.0 dB, (-1000 to 120) in 0.1 dB increments.
NOTE: The integers only need to be signed if they are a
negative number.
