dbx iEQ31 Dual 31-Band Graphic EQ/Limiter with Type V NR and AFS

The iEQ31 pairs an analog front end with a digital core, so a room tech gets two 31-band, 1/3-octave Constant Q graphic channels alongside built-in AFS feedback suppression and Type V dynamic noise reduction in a single 1U frame. Boost/cut range switches between 6 and 15 dB per band, and the 24-bit, 48 kHz digital section adds only 2 milliseconds of latency to the signal path.

Inputs and outputs are on 1/4 inch TRS, XLR (pin 2 hot), and Euroblock, handling over +22 dBu at the input and over +20 dBu out. Noise reduction pulls up to 10 dB of dynamic broadband hiss out of the signal without a separate box, and dynamic range runs past 113 dB A-weighted. The chassis measures 3.5 x 19 x 7.9 inches and runs on a universal 120/220-240 VAC supply drawing 17 watts.
