8.113. PEQOF -- Set Frequency Parameter for Specified
Parametric EQ Output Stage
This command sets or queries the frequency parameter (in Hz) 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 frequency parameter are 20 and 20000, respectively.
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
F01PEQOF3,2,1250
Set frequency of parametric EQ
on output 3 , band 2 to 1250 Hz.
F01PEQOF3,2,1250
F01PEQOFB,1,?
Query current frequency setting
of parametric EQ on output B ,
band 1.
F01PEQOFB,1,f , where f is the current setting of
the frequency parameter for the parametric EQ on
output 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
F01PEQOFB,1,1250 .
8.114. 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
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
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.
