ART XL 231 Dual 31 Band, 1/3 Octave Extended, Long Throw, Professional Equalizer

FRONT PANEL CONTROLS

POWER SWITCH
To turn the equalizer ON or OFF, press (and release) the POWER ON/OFF button.
CAUTION: Always turn on your mixer and 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 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) for maximum boost/cut
flexability. 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).
ENHANCED CUT MODE
The XL 231 offers an Enhanced Cut mode which has a more narrow filter bandwidth
and additional cut range of -18dB. This helps when trying to tame resonance and
minimizing overall spectral changes. When Enhanced Cut is used with the ÷2 range, the
maximum cut is -9dB instead of -18dB. As can be seen in the graphs below, only filter
cut shapes are affected, boost curves are the same regardless of cut mode.
