Overview
Alesis DEQ830 Programmable Digital Graphic Equalizer
Long known as a company that provides maximum bang for the buck, Alesis is proud to debut the DEQ830 Graphic Equalizer. Based on Alesis' extraordinary technology, this new programmable rackmount EQ gives recording engineers and live sound professionals an expanded feature set, enhanced 24-bit sound quality, and more flexible routing options than any other EQ in their class. The DEQ830 boasts eight independent programmable 1/3-octave graphic EQs in an amazingly compact 1U rackmount design. Its connections include eight balanced 1/4 in. TRS analog I/O and eight channels of ADAT Optical digital I/O, making the DEQ830 the perfect EQ unit for a range of modern recording applications. Other standout features include 100 user-customizable EQ programs, 50 template 'curves' for rapid setup, and +4dBu/-10dBV switchable operation - allowing a high degree of user customization. Rounded out with an ultra-intuitive user interface and MIDI I/O, the DEQ830 is everything a high-end programmable EQ should be, without the high-end price tag.

"good idea bad construction"
i think alesis should make a DEQ830MKII with good converters, external power suply, 96khz dual smux adats and then... wow!!
Sound
this device is hiss like a snake!!! the analog outputs are very noizy even if there is no signal. cheap AD / DA converters! the power supply inside the box, is working all the time since the device is plugged to the wall socket and the noize is present from this power supply also.
Features
very good idea to build such a device! it has all the futures you can expect from a digital eq. it will be much better if it was 96khz compatible and the eq gain to be at +/- 16 or 18 db and not only at 12.
Ease of Use
very easy and simple
Quality
the sound is noizy!!! i've try to boost the hi frequencies and it was a disaster.
Value
killing price! party time!
Manufacturer Support
this device has been released for a very short period and alesis stops to produce it. i think this is the most short time model on the market!!! i never get an answer to my e-mails what can i do for this noise...
The Wow Factor
i want it very bad! i was almost ready to order 2 of them. but when i tried the first one, that noise was a nightmare
