Dual 31 EQ with Feedback Detection Circuit/ Variable Hi and Lo Pass Filters

HQ 231

Overview

The HQ231 Dual 31-band Graphic EQ is perfect for any live sound application where there is a high feedback potential including monitor mixes, side-fill cabinets or high powered front-of-house mixes situations​.

ART’s proprietary FDC™ within the HQ231 (Feedback Detection Circuitry – designed and developed by ART Engineering) instantly illuminates an LED on the corresponding EQ band fader with the greatest sustained signal. The LED indicators can immediately show which band corresponds to the feedback frequency, allowing the sound engineer to reduce gain in that band to quickly kill the feedback while having a minimal impact on the sound of the live program material.

Constant-Q Filtering helps the HQ’s FDC work with greater efficiency while offering superior overall performance of the EQ. Constant-Q ensures that even when making radical adjustments to a frequency band, that adjacent bands will not be affected. This is particularly critical in professional applications including monitor mixes and feedback control.
