INTRODUCTION
The new ART XL 231 Dual 31 Band, 1/3 Octave Extended Long Throw Professional
Equalizer has been designed and engineered to exceed extremely high standards for
audio performance and functionality. This innovative, high-quality equalizer is perfect for
virtually any audio application where precision frequency tailoring, reliable performance,
rugged design and extremely silent processing are of the utmost priority.
Active Filter Sections
The XL 231 features active filter sections, which incorporate a constant-Q design.This
constant-Q design, with its accurate precision center frequencies, ensures that the
bandwidth of every individual filter will be narrow enough to prevent unnecessary
interaction between ajacent filters, yet still create an equalization curve wide enough to
produce the exact and precise processing of audio frequencies the user seeks.
Filter circuitry incorporates high quality low noise components including 1% resistors,
and, precision high performance 2% film capacitors.
Enhanced Cut Mode
The XL 231 offers an enhanced cut mode which allows more narrow filters and deeper
cut of -18dB. This helps when trying to tame resonance and minimizing overall spectral
changes. Only each filter’s cut mode is enhanced while their boost characteristic
remains unchanged.
Precision Slide Potentiometers
The XL 231 uses 45mm precision slide potentiometers. These center-detented, metal
shaft precision faders are graphically positioned on ISO center frequencies between
20Hz to 20kHz. The sliders feature a grounded center tap to assure that the filter is out
of the circuit when the control is at its center detent.
Hi and Low Trim controls
These unique controls allow a gentle slope to be added, or subtracted from the overall
frequency response. Both controls hinge at the middle of the spectrum and allow subtle
changes to the overall sound without the need to adjust many sliders. Although similar
in concept to tone controls, these differ in their well controlled precision straight curves,
and, have less selectivity so the Trim controls don’t have a “sound” as a typical tone
control will.
