30 bands of extremely graphic EQ....

It wouldn’t be a stretch to call Alesis “The Graphic EQ Company.” Our 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 DEQ230D updates our acclaimed DEQ230 with S/PDIF digital I/O and an internal power supply, keeping the same extensive programmability and intuitive, WYSIWYG-enabled user interface. And the latest addition, the DEQ224, gives a whole new meaning to “space-efficient,” packing two channels of 24-band digital EQ into a half rackspace.

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.

Music by you. Graphic design by Alesis.
