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
F01PEQIT3,2,1
Set the type of the parametric EQ on
input 3 , band 2 to parametric.
F01PEQIT3,2,1
F01PEQITB,1,?
Query current type setting of
parametric EQ on input B , band 1.
F01PEQITB,1,t , where t is the current setting of
the type parameter for the parametric EQ on input B
, band 1. If the type parameter of this filter is set to
the same value given in the example above, then
the status message will be F01PEQITB,1,1 .
8.110. PEQOA -- Set All Parameters for Specified Parametric EQ
Output Stage
This command sets or queries all of the parameters 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 output parametric EQ filter parameters can be set individually via the
PEQOT, PEQOF, PEQOB, PEQOG,
PEQOS, and PEQOE commands. The input parametric EQ filter parameters can be set simultaneously via the
PEQIA command or individually with the PEQIT, PEQIF, PEQIB, PEQIG, PEQIS, and PEQIE commands.
When using this command, you must specify all of the following parameters.
Description Value Range Units
Channel 1-8, A-D N/A
Band 1-5 N/A
Filter Type 1-5
1 = parametric filter
2 = low shelf
3 = high shelf
4 = lowpass
5 = highpass
6 = Linkwitz-Riley lowpass
7 = Linkwitz-Riley highpass
Frequency 20 - 20000 Hz
Bandwidth 5 - 200 1/100th octave
Gain -20 - 20 dB
Slope 1 - 1.2 * Gain for shelving filters, 12 or 24 for Linkwitz-Riley filters dB per octave
Enable 0 - 1
0 = filter disabled
1 = filter enabled
The paramters are specified in the order shown and are separated by commas. The wildcard character, *, may
not be used for any of the parameters listed above. If an attempt is made to set one of the parameters outside
the valid range, the command will fail and return an error message of ERROR#002.
Not all of the parameters are valid for each of the filter types. The following table shows which parameters are
used in each of the filter types.
