28 PEQ-450 Reference Manual
Description of Controls
There are five groups of knobs in vertical rows on each channel of
the PEQ-450. These are labeled BAND 1 through BAND 5. Their
function is as follows:
Gain
The GAIN
G
knob specifies the amount of boost or cut for that band.
The range of the control is –18dB to +18dB. When the Gain is set to
0dB, that band will not affect the audio. The only exception to this is
if the
LPF or HPF functions are on. These functions supercede the gain
setting on Band 1 and Band 5.
