Alesis DEQ830 8 Channel Digital Graphic EQ Details

Alesis DEQ830 – It wouldn’t be a stretch to call Alesis “The Graphic EQ Company.” Our Alesis MEQ230 is a standard in sound installations and studios, and the DEQ series now carries the torch with a groundbreaking approach to digital graphic EQs – for every application and budget – that’s taking engineers by storm.

The Alesis DEQ830 is the world’s most affordable 8-channel 1/3-octave digital graphic EQ. Though it fits in a compact one-space rack, we didn’t skimp on connections or features. Sonic performance is superb, with 1/4″ TRS balanced and ADAT Optical I/O.

Change any of 30 bands on eight discrete channels with the press of a button. Get instant, slider-style visual feedback rather than squinting at a tiny LCD. And store your changes in 100 user programs, with 50 curve templates to get you started in any room.

From tweaking project studio acoustics to tuning a concert hall to balancing a mix, Alesis graphic EQs give you more features and better audio performance than any units in their price range.
