The iA231F
is a multi-functional two-channel graphic equalizer with 1/3 octave
31-band ISO frequencies. It features an on-board feedback detection
system that can be placed in active or bypass mode. When active it
seeks out feedback and helps to destroy it by illuminating an LED on
the frequency band slider when feedback is detected. The LED stays lit
until the feedback has been eliminated; giving you the vital
information you need to level feedback in your system.
The frequency
band boost/cut range can be set at 6 or 12 dB. This allows for greater
refinement of the bands at 6 dB, or more boost and cut at 12 dB. A
stereo link function lets you combine the left and right channels and
assign the same settings to both of them with one row of frequency
bands. Variable low and high cut 18 dB/octave Butterworth filters let
you roll off unwanted frequencies, and a limiter is selectable down to
-20 dB.
Other features include two sub outputs with individual variable
crossover frequencies, EQ bypass mode and an 8-segment level meter that
allows you to monitor input or output. Connection is through balanced
1/4" TRS phone or XLR-type input and output connectors with selectable
operating levels at +4 and -10 dB. The built-in switching power supply
means that this EQ is ready to travel and will work almost anywhere in
the world. D digital models include AES and S/PDIF input and output with sampling rates that can be set at 44.1, 48 or 96 KHz.
