OPERATION
FRONT PANEL CONTROLS
POWER SWITCH
To turn the equalizer on or off, press the upper or lower portion of the POWER switch. CAUTION:
Always turn on your equalizer BEFORE your power amplifiers are turned on, and always turn off your
equalizer AFTER your power amplifiers have been turned off.
FILTER LEVEL CONTROLS
Each of these sliders controls the signal level of each of the 31 (or 15) bandpass filters. A detent at
the center position helps center the controls for a flat response.
FILTER RANGE SWITCH & INDICATORS
The gain range of the filter sliders is switchable (as a group) from ±6dB to ±12dB for maximum
boost/cut capability. At ±6dB the green LED will illuminate, and at ±12dB the yellow LED will
illuminate.
BYPASS SWITCH & CLIP INDICATOR LED
When the red BYPASS LED is illuminated, this indicates that the unit or channel is in the bypass
mode. Signal is routed directly from the input to the output without passing through any circuitry (often
referred to as ”hard-wire bypass”). Use this switch to compare equalized and unequalized material, or
to bypass the EQ section in the event of total unit failure.
The red CLIP LED illuminates if any section of the equalizer is near clipping. Occasional flickering of
this LED is acceptable, but if it remains on more than intermittently, you should reduce the output
level of the preceding equipment or, if that is not possible, turn down the equalizer’s LEVEL control to
avoid audible distortion.
