Q
Q controls the "sharpness" of the filter. For the PEAK and SUB_EQ filter types, lower Q gives a
shallower peak or dip, while higher Q gives a narrower peak or dip. For the HIGH_SHELF and
LOW_SHELF filter types, Q controls how quickly the filter transitions from no gain to maximum
gain.
To disable or enable a filter, click on the Bypass button. A filter will also have no effect if its gain is set to 0.0.
Other filter types can be created by switching to Advanced mode. In this mode, the coefficients of each filter
"biquad" are entered individually. The coefficients will need to be calculated by a filter design program. A useful
spreadsheet for a number of filter types is available on the miniDSP.com website – see the application note
Advanced Biquad
Programming.
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 left and right channels are linked: front left and
right, surround left and right, and rear surround left and right. 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.
