9.3.3 Parametric EQ

Parametric equalization (PEQ) is a flexible type of equalization filter. It can be used to correct for errors in

loudspeaker output, to compensate for acoustic room effects, and to tailor the overall system response for best

sound. Click on the PEQ button to open the parametric equalizer settings window:

There are ten parametric EQ filters on each output channel. The window displays a frequency response graph

showing the combined response of all enabled parametric filters on that channel. For example, the screenshot

above shows a response curve created with a low-shelf boost filter at 100 Hz, a dip at 500 Hz, and a high-shelf

cut filter at 5000 Hz.

Hovering the mouse over the curve brings up an overlay showing the frequency and the gain at that frequency.

Each channel can be linked to one other channel. When a channel is linked to another, the PEQ settings of that

channel are mirrored to the other. Typically, corresponding channels on the left and right are linked: for

example, left and right tweeter and left and right woofer. To link a channel, select the other channel from the

drop-down menu at the top left of the PEQ display, and click the Link checkbox.
