Manufacturer's Description 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.

 

Features

 ♦ Premium 8-channel super-compact analog mixer with integrated Fire wire I/O

 ♦ 2 mono channels (mono mic and mono line inputs)

 ♦ 1 hybrid channel (mono mic and stereo line inputs)

 ♦ 2 stereo channels (stereo line inputs)

 ♦ 3 Onyx mic preamps with sound comparable to boutique preamps

 ♦ 2 channels of FireWire monitoring routable to either the control room or channels 7 and 8

 ♦ 2 independent aux sends with separate pre/post switches

 ♦ Selectable instrument inputs on first two channels – no DI box is needed

 ♦ Individual 48v phantom power switches on all mic inputs

 ♦ Talkback section with built in mic and fl exible routing

 ♦ "Planet-Earth" switching power supply for worldwide use

About Manufacturer

We have the technology. A good mixer is more than just a bunch of knobs and faders. When you think about it, it's the stuff underneath the cover behind the knobs and faders that makes or breaks a mixer. We've built our reputation by making affordable mixers loaded with highly useful features But those features wouldn't mean diddley if they weren't built on solid technology. And that's why we've assembled a bunch of text chunks that describe what goes into every Mackie mixer.
We hope you will read through the various chunks before you make a buying decision. Then buy a Mackie mixer so our Corporate Chihuahua can finance the creation of an original screenplay based on her exciting life. Coming soon to a theater near you.
