page allows the user to assign a status function to one of the 20
logic status outputs. The status functions could include AEC On or Off, AGC On or
Off, NOM Attenuation, Camera Gating, Gating, Mic or Line Level, Muting, Noise
Cancellation, and Phantom Power On or Off. To assign a status function to the status

button will show the command syntax.
To create status output that is a logical combination of particular inputs or outputs, use
the logical syntax (+, 0, or 1). For instance, to create a status output that will be set
when Input Channels 1 AND 3 are muted, the syntax is ’MUTE*1.1.....’. To
create a muting status output that will be set when Input Channels 1 OR 3 are muted,
the syntax is ’MUTE*+.+.....’. Notice that the MUTE* status command can take
up to 12 arguments, one for each input. The gating status command GATE* takes 8
arguments since only Inputs 1-8 can be gated.
The polarity of the outputs can also be changed by right-clicking on the pin number.
