Alesis DEQ-830 - 8-Channel Digital 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 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.

  • "I want to thank Caylen Staub and All Pro Sound for helping me make the right decision on my new Allen & Heath QU-16 console purchase. I didn't know anything about the board and was very apprehensive about buying it. Caylen patiently explained the features and how the board would fulfill my sound needs. I even had second thoughts after receiving it and he talked me through my concerns. He guaranteed I would enjoy the board and he was absolutely right."
    Phillip S. - Richmond, VA
  • "Thank you for putting together the portable projection system for our church. It is exactly what we needed. We received the screen today and I set it up this afternoon. Even in our brightly lit sanctuary on a sunny day with lots of large windows the projector shown brightly with vivid color. I will be sure to call All Pro Sound with any of our future Audio Visual needs. It has been a pleasure working with you."

But more than your products, your customer service is second to none. I always deal with Mike Tipton, who is SUPER knowledgeable about all of your products, and SUPER helpful. In short: Mike is awesome! It is always great working with him!"

For the past year we have been assisting a fellow church within our denomination with their audio / media design for their new sanctuary. A very special thank you to John Teelin and Steve Maples from All Pro Sound. From the pre wiring stage to the rush deliveries at the finish line, these guys have been there the whole way. Thank you All Pro Sound! We could not have done it without you!!!"
