[. . . ] HQ-231 DUAL 31-BAND GRAPHIC EQUALIZER WITH FDC FEEDBACK DETECTION CIRCUIT TM The ART HQ-231 Dual 31-Band EQ features ART's proprietary FDCTM (Feedback Detection Circuit) found exclusively in ART equalizers. [. . . ] This precision is, of c o u r s e, absolutely critical for professional applications and situations where top audio Professional quality features, functionality and performance is a requirement. The HQ-231 has Constant- Additionally, FDC enables you to observe those Q filtering with ISO centers, independent variable frequency bands with the greatest energy when high-pass and low-pass filters, LED-illuminated program material is being played, and can help detented slide potentiometers, switchable +/- 6db to quickly locate dominant room modes during or +/-12db boost/cut range, independent level and system setup. The HQ-231 is extremely useful for equalization During operation, various EQ band LED's will and feedback elimination in a wide variety of illuminate as the HQ-231 processes a signal.
