1. Introduction
The EQ231G is a high quality dual 31-band 1/3 octave graphic equaliser with variable
12dB per octave Hi-pass filter. A delayed by-pass relay allows silent on/off switching
and also provides direct throughput when the unit is not powered. Centre detented,
45mm faders give up to 12dB of cut and boost at 31 ISO centre frequencies, covering
the entire audio spectrum (20 to 20KHz). Inputs and outputs are electronically
balanced. Each channel has a Peak Indicator illuminating for an equivalent output
signal of +18dBu.
Options
The unit can be augmented by parallel outputs offering a unique transformer distortion
cancellation circuit. This reduces distortion by an order of magnitude compared to
conventional designs and also provides galvanic isolation from connected devices for
the reduction of interference and hum.
