OPERATING INSTRUCTIONS
Before starting to equalize your sound system there is some information you should
know and procedures you should follow. Your equalizer is equipped with a bypass
switch. The bypass switch, when activated, lights the bypass red LED and cancels all
equalization settings while allowing signal to flow directly through the unit at unity gain.
When in the active state, the green LED is on.
Also included is a range selection switch. Normal range is ± 12dB (+12/-18 when
Enhanced Cut Mode is active). When Fader Range is set to ÷2, the yellow LED is
illuminated and the range is cut in half to ±6dB (+6/-9 when Enhanced Cut Mode is
active). In addition to the range selection switch there is an output level control
potentiometer. The level control operates between off and +6dB.
Note: If there is too much input signal, or, the equalizer has many filter bands boosted,
the red LED Clip indicator will indicate when signals are within 6dB of clipping. If the
Clip LED flashes occasionally, this is okay, but if this LED is steadily on you should
reduce the input signal level or the amount of boost in the filter bands. Reducing the
output level will not reduce clipping if it occurs.
INITIAL SET UP
Here are some tips to help you with the initial set up:
1. Set channel output levels to the center 0dB on the front panel.
2. Select the Bypass switch to bypass the equalizer (Note: The red LED is on).
3. Set the frequency band slide controls to the center detent (0dB).
4. Set the Low Cut filter to 10Hz.
5. Select the ÷2 range (Note: The yellow LED is on).
6. Apply signal to the system and if the Clip LED is on, reduce your signal to the unit.
7. Release the bypass switch (Note: The red LED is off, the green LED is on.).
8. You may now start equalizing your system.
9. If you do not have enough equalization control, release the Fader Range switch to
the out position, yellow LED off.
