From Mackie
A BETTER WAY TO RECORD
Onyx-i mixers offer professional analog features like boutique-quality Onyx mic preamps, classic “British-style” Perkins EQ and pre/post assignable aux sends, all of which can be flexibly routed via an integrated ultra-high quality 24-bit/96kHz FireWire recording interface.
The Onyx i series of mixers offer built-in FireWire, along with the newest features and latest technologies for live sound reinforcement and analog or digital studio recording, all in a durable, road-worthy package.
The Onyx 820i is equipped with three of our premium precision-engineered studio-grade Onyx mic preamps. Mackie is renowned for the high-quality mic preamps used in our mixers, and the Onyx mic pre’s are better than ever, with specifi cations rivaling expensive stand-alone mic preamplifiers. Channels 1 and 2 feature high-impedance instrument/line-level inputs so you can connect an acoustic, electric, or bass guitar directly into the mixer, eliminating the need for an external direct box.
