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.
