8.114. PEQIA -- Set All Parameters for Specified Parametric
EQ Input Stage
This command sets or queries all of the parameters for the parametric equalizer (EQ) filters on input
channels 1, A, B, and T input channel T. Each channel has five bands of parametric EQ that can be
independently controlled.
The input parametric EQ filter parameters can be set individually via the
PEQIT, PEQIF, PEQIB,
PEQIG, PEQIS, and PEQIE commands. The output parametric EQ filter parameters can be set
simultaneously via the
PEQOA command or individually with the PEQOT, PEQOF, PEQOB, PEQOG,
PEQOS, and PEQOE commands.
When using this command, you must specify all of the following parameters.
Description Value Range Units
Channel 1, A, B, T 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 parameters 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.
