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.
