Polycom Vortex EF2280 User Manual

before the automixer (ungated) or after the automixer (gated). This command selects the gated or ungated
microphone signal. If MGATE is set to 1 for a given crosspoint, then the signal will be gated (taken after the
automixer). If MGATE is set to 0 for a given crosspoint, then the signal will be ungated (taken before the
automixer).
This command is a matrix boolean command. See
Section 6.4 and Section 6.1 for more information on this type
of command.
This command is saved to non-volatile memory only as part of a preset. The state of this command will be
restored after power-up only if a preset is saved and that preset is set to be the power-on preset.
Example Description Status Message
F01MGATE3,A,1
Select the gated version
of microphone input 3 to
be sent to output A.
F01MGATE3,A,1
F01MGATE3,A,0
Select the ungated
version of microphone
input 3 to be sent to
output A.
F01MGATE3,A,0
F01MGATE3,A,2
Toggle the gated status of
the crosspoint that routes
microphone input 3 to
output A.
F01MGATE3,A,x , where x is 0 or 1 depending on the
current gated status of the crosspoint.
F01MGATE3,A,?
Query the gated status of
the crosspoint that routes
microphone input 3 to
output A.
F01MGATE3,A,x , where x is 0 or 1 depending on the
current gated status of the crosspoint.
F01MGATE*,A,1
Select the gated version
of all microphone inputs
to be sent to output A.
F01MGATE*,A,11111111 -- note that there are only
eight values returned, since only the eight microphone
inputs can be gated. The other inputs do not pass
through the automixer.
F01MGATE*,A,0
Select the ungated
version of all microphone
inputs to be sent to
output A.
F01MGATE*,A,00000000 -- note that there are only
eight values returned, since only the eight microphone
inputs can be gated. The other inputs do not pass
through the automixer.
F01MGATE*,A,11110000
Select the gated version
of microphone inputs 1-4
to be sent to output A and
the ungated version of
microphone inputs 5-8 to
be sent to output A.
F01MGATE*,A,11110000
F01MGATE*,A,?
Query the gated status of
all microphone inputs
routed to output A.
F01MGATE*,A,abcdefgh, where a-h are each 0 or 1
depending on the current gated status of each
crosspoint.
8.90. MIC -- Enable Microphone Gain Stage on Inputs 1-8
This command sets or queries the enabled state of the microphone gain stages on each of the microphone inputs
. Enabling the gain stage adds an extra 33 dB of gain in the input signal path. See the description of the
GAINI
command for information on how the MIC and
GAINI commands relate to nominal input levels.
