Range: Allows selection of ±6 dB or ±12 dB boost or cut.
Color-coded LED’s indicate the range selected.
Bypass: Toggles the EQ between IN and OUT (bypassed).
A yellow LED glows to indicate Bypass.
Low Pass Filter: Decreases the higher frequencies. Useful
in reducing hiss or sibilance. The filtering range is
continuously adjustable from 3 kHz up to 50 kHz.
High Pass Filter: Decreases the lower frequencies, to
combat rumble, footsteps, wind noise, etc. Continuously
adjustable from 10 Hz to 250 Hz.
Level Control: This control may be used to compensate
for any changes in volume caused by the EQ settings.
Clip LED: Indicates a distortion-causing overload. Adjust
the Level control to compensate for clipping.
EQ Sliders: These sliders allow boost or cut of either ±6
dB or ±12 dB (depending on the setting of the Range switch)
over a narrow frequency band.
Ground Lift: Fights hum or buzz by separating the signal
and chassis grounds.
