parameter, the filter type, 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 PEQOT 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

S01PEQIT1,2,1

S01PEQITB,1,?

Description

Set the type of the parametric EQ on input 1 , band 2 to parametric.

Query current type setting of parametric EQ on input B , band 1.

Status Message

S01PEQIT1,2,1

S01PEQITB,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 S01PEQITB,1,1 .

8.121. 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, A, B, and T output channel T. 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.
