Product Description from Mackie:
The Onyx 1220, 1620 and 1640 start with all-new premium analog circuitry, setting new standards for high-headroom, low-noise operation. Next up are Mackie's new Onyx mic preamps, which meet or surpass expensive esoteric standalone mic preamps in terms of fidelity and transparency. Then there's the completely new Perkins EQ circuitry, a 'neo classic' 3- and 4-band design which gives you the sweet musicality of British EQ with greater filter control and minimum phase shift (plus a true hardware EQ bypass). And all this analog innovation is rounded out by a new Aux section w/ individual Pre/Post control, plus a new Talkback section with built-in mic for easy studio communication.
In addition to balanced direct outputs on every channel via dual DB-25 connectors (a first for any small-format analog mixer), you can outfit each Onyx mixer with an optional FireWire I/O card, which lets you stream either 12 or 16 independent channels of 24-bit/96k audio, plus a stereo mix, directly to your Mac or PC. You can also monitor a stereo mix via FireWire from your computer, making the Onyx Series mixers superb audio interfaces to your digital world... or any other world you plan to rule.
