frequencies
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.
IA231FD digital models include AES and S/PDIF input and output with
sampling rates that can be set at 44.1, 48 or 96 KHz.
