Polycom Vortex EF2280 User Manual

This command has the same format and restrictions as the PEQIA command except that only one parameter, the
frequency, is specified instead of all the parameters. See the
PEQIA command for more information. To set the
frequency parameter for an output parametric EQ filter, use the
PEQOF command. To set all the parameters for
an output parametric EQ filter, use the
PEQOA 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
F01PEQIF3,2,1250
Set frequency of parametric EQ
on input 3 , band 2 to 1250 Hz.
F01PEQIF3,2,1250
F01PEQIFB,1,?
Query current frequency setting
of parametric EQ on input B ,
band 1.
F01PEQIFB,1,f , where f is the current setting of
the frequency parameter for the parametric EQ on
input B , band 1. If the frequency parameter of this
filter is set to the same value given in the example
above, then the status message will be
F01PEQIFB,1,1250 .
8.107. PEQIG -- Set Gain Parameter for Specified Parametric EQ
Input Stage
This command sets or queries the gain parameter (in dB) for the parametric equalizer (EQ) filters on input
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 gain parameter are -20 and 20, respectively.
This command has the same format and restrictions as the
PEQIA command except that only one parameter, the
gain, is specified instead of all the parameters. See the
PEQIA command for more information. To set the gain
parameter for an output parametric EQ filter, use the
PEQOG command. To set all the parameters for an output
parametric EQ filter, use the
PEQOA 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
F01PEQIG3,2,-20
Set the gain of the parametric EQ on
input 3 , band 2 to -20 dB.
F01PEQIG3,2,-20
F01PEQIGB,1,?
Query current gain setting of
parametric EQ on input B , band 1.
F01PEQIGB,1,g , where g is the current setting
of the gain parameter for the parametric EQ on
input B , band 1. If the gain parameter of this filter
is set to the same value given in the example
above, then the status message will be
F01PEQIGB,1,-20 .
8.108. PEQIS -- Set Slope Parameter for Specified Parametric EQ
Input Stage
This command sets or queries the slope parameter (in dB per octave) for the parametric equalizer (EQ) filters on
