Polycom Vortex EF2280 User Manual

This command sets or queries the bandwidth parameter (in 1/100th octaves) for the parametric equalizer (EQ)
filters on output channels 1-8 and A-D . Each channel has five bands of parametric EQ that can be independently
controlled.
The minimum and maximum values for the bandwidth parameter are 5 and 200, respectively.
This command has the same format and restrictions as the
PEQOA command except that only one parameter, the
bandwidth, is specified instead of all the parameters. See the
PEQOA command for more information. To set the
bandwidth parameter for an input parametric EQ filter, use the
PEQIB command. To set all the parameters for
an input parametric EQ filter, use the
PEQIA 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
F01PEQOB3,2,40
Set bandwidth of parametric EQ on
output 3 , band 2 to 40 1/100th
octaves.
F01PEQOB3,2,40
F01PEQOBB,1,?
Query current bandwidth setting of
parametric EQ on output B , band 1.
F01PEQOBB,1,b , where b is the current setting of
the bandwidth parameter for the parametric EQ on
output B , band 1. If the bandwidth parameter of this
filter is set to the same value given in the example
above, then the status message will be
F01PEQOBB,1,40 .
8.112. PEQOE -- Set Enabled Parameter for Specified Parametric
EQ Output Stage
This command sets or queries the enabled parameter (0 = filter is disabled, 1 = filter is enabled) for the
parametric equalizer (EQ) filters on output channels 1-8 and A-D . Each channel has five bands of parametric EQ
that can be independently controlled.
This command has the same format and restrictions as the
PEQOA command except that only one parameter, the
enabled status, is specified instead of all the parameters. See the
PEQOA command for more information. To set
the enabled parameter for an input parametric EQ filter, use the
PEQIE command. To set all the parameters for
an intput parametric EQ filter, use the
PEQIA 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
F01PEQOE3,2,1
Enable parametric EQ on output 3 ,
band 2.
F01PEQOE3,2,1
F01PEQOEB,1,?
Query enabled status of parametric EQ
on output B , band 1.
F01PEQOEB,1,e , where e is the current setting of
the enabled parameter for the parametric EQ on
output B , band 1. If the enabled parameter of this
filter is set to the same value given in the example
above, then the status message will be
F01PEQOEB,1,1 .
