Parametric EQ (PEQ)
Parametric equalization (PEQ) is a flexible type of equalization filter. It can be used to correct for errors in driver
response when implementing an active speaker system. Click on the PEQ button to open the parametric
equalizer settings window:
There are 10 parametric EQ filters on each input and output channel. The window displays a frequency response
graph showing the combined response of all enabled 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, the corresponding drivers on the left and right channels are linked:
left and right tweeter, left and right woofer, and so on. To link a channel, select the other channel from the
drop-down menu at the top left of the
PEQ
screen, and click the
Link
checkbox.
