Alesis DEQ830 Digital EQ
The DEQ830 from Alesis is a digital, 8-channel graphic EQ housed in a one-space, rack mount enclosure. The EQ offers 30 bands of equalization, linkable or independent, with 12dB of cut or boost. The unit operates at Constant Q, a process in which the range of frequencies affected by a single band stays the same regardless of the amount of cut or boost.
Although the unit functions in the digital domain, analog-style controls are provided for instant editing of any band or combination of bands. Any of the 30 bands can be viewed on eight discrete channels at the switch of a button and any changes stored in 100 user programs. A Real-time Analyzer (RTA) mode with selectable metering allows for visual feedback of incoming and outgoing audio signals.
Audio quality is preserved using 24-bit analog to digital and digital to analog conversion with internal processing carried out using 28-bit word lengths. The DEQ830 can operate at either a +4dBu or -10dBV setting.
