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:
• Mic/Line Input (gain and mute) • Virtual Return (gain and mute)
• Aux Input (gain, mute, and source) • Post-mixer (gain only)
• Pre-mixer (gain and mute) • Output (attenuation and mute)
• Mix-points (gain and mute)
Symbol Definitions
]
= Carriage return/line feed
}
= Carriage return (no line feed)
•
= Space character
|
=
Pipe (can be used interchangeably with the
} character)
E
= Escape key
W
=
Can be used interchangeably with the
E character
X7@
= Gain and trim control See Object ID (OID) Number Tables on page151.
X7#
= Level value 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 103 (10.3 x 10), if the desired gain value
is -8.2 dB, the SIS value would be -82 (-8.2 x 10), and so on.
-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.
X7$
= Mute status 0 = unmute
1 = mute (see Object ID (OID) Number Tables on page151)
X7%
= Group master group number 01 through 64
X7^
= Group fader setting dB, value in 0.1 dB increments using a 10x multiplier and
negative numbers, but not decimal places. The valid range
depends on the type of gain block that is assigned to the group
number X7% specified in the command:
-180 to 800 (-18.0 dB to +80 dB)
-1000 to 120 (-100.0 dB to +12.0 dB)
-1000 to 120 (-100.0 dB to +12.0 dB)
-120 to 120 (-12.0 dB to +12.0 dB)
-1000 to 0 (-100.0 dB to +0.0 dB)
NOTE: Leading zeros are ignored.
