Polycom Vortex EF2201 User Manual

For filter types that have a center frequency (e.g., parametric), this parameter specifies the center
frequency. For filter types that have a cutoff frequency (e.g, highpass, lowpass, etc.), this parameter
specifies the cutoff frequency.
This command has the same format and restrictions as the
PEQOA command except that only one
parameter, the frequency, is specified instead of all the parameters. See the
PEQOA command for more
information. To set the frequency parameter for an input parametric EQ filter, use the
PEQIF
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
T01PEQOFT,2,1250
Set frequency of parametric
EQ on output T, band 2 to
1250 Hz.
T01PEQOFT,2,1250
T01PEQOFT,1,?
Query current frequency
setting of parametric EQ on
output T, band 1.
T01PEQOFT,1,f, where f is the current setting
of the frequency parameter for the parametric
EQ on output T, 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 T01PEQOFT,1,1250.
8.89. PEQOG -- Set Gain Parameter for Specified Parametric
EQ Output Stage
This command sets or queries the gain parameter (in dB) for the parametric equalizer (EQ) filters on
output channel T. 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
PEQOA command except that only one
parameter, the gain, is specified instead of all the parameters. See the
PEQOA command for more
information. To set the gain parameter for an input parametric EQ filter, use the
PEQIG 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
T01PEQOGT,2,-20
Set the gain of the parametric
EQ on output T, band 2 to -20
dB.
T01PEQOGT,2,-20
