Example Description Status Message
F01PEQIB3,2,40
Set bandwidth of parametric EQ on
input 3 , band 2 to 40 1/100th
octaves.
F01PEQIB3,2,40
F01PEQIBB,1,?
Query current bandwidth setting of
parametric EQ on input B , band 1.
F01PEQIBB,1,b , where b is the current setting of
the bandwidth parameter for the parametric EQ on
input 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
F01PEQIBB,1,40 .
8.105. PEQIE -- Set Enabled Parameter for Specified Parametric
EQ Input Stage
This command sets or queries the enabled parameter (0 = filter is disabled, 1 = filter is enabled) 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.
This command has the same format and restrictions as the
PEQIA command except that only one parameter, the
enabled status, is specified instead of all the parameters. See the
PEQIA command for more information. To set
the enabled parameter for an output parametric EQ filter, use the
PEQOE 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
F01PEQIE3,2,1
Enable parametric EQ on input 3 ,
band 2.
F01PEQIE3,2,1
F01PEQIEB,1,?
Query enabled status of parametric EQ
on input B , band 1.
F01PEQIEB,1,e , where e is the current setting of
the enabled parameter for the parametric EQ on
input 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
F01PEQIEB,1,1 .
8.106. PEQIF -- Set Frequency Parameter for Specified
Parametric EQ Input Stage
This command sets or queries the frequency parameter (in Hz) 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 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.
