(EQ) filters on input channels 1, A, B, and T . Each channel has five bands of parametric EQ that can be independently controlled.

For the Linkwitz-Riley filters, the slope can either be 12 or 24 (dB/Octave).For the low shelf and high shelf filters, the minimum value for the slope parameter is 1, and the maximum value is 1.2 times the current value of the gain parameter. See the PEQIG command for information on the gain parameter.

This command has the same format and restrictions as the PEQIA command except that only one parameter, the slope, is specified instead of all the parameters. See the PEQIA command for more information. To set the slope parameter for an output parametric EQ filter, use the PEQOS 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

Set the slope of the parametric EQ

S01PEQIS1,2,1 on input 1 , band 2 to 1 dB per octave.

Query current slope setting of

S01PEQISB,1,? parametric EQ on input B , band 1.

Status Message

S01PEQIS1,2,1

S01PEQISB,1,s , where s is the current setting of the slope parameter for the parametric EQ on input B , band 1. If the slope parameter of this filter is set to the same value given in the example above, then the status message will be S01PEQISB,1,1 .
