ONYX 800R

Introduction

Thank you for choosing a Mackie Onyx 800R eight- channel professional microphone preamplifier. The Onyx Series of mixers and microphone preamps are designed for the digital era and offer the newest features and latest technologies for live sound reinforcement and analog or digital studio recording in a durable, road-worthy package.

The Onyx 800R is equipped with eight of our new 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 specifications rivaling other stand-alone mic preamplifiers at twice the price.

The Onyx 800R is designed to be a transparent audio interface for direct tracking to MDM, HDR, or DAW re- cording applications. Its selection of analog and digital output options provides the flexibility to connect in almost any application.

Channels 1 and 2 feature an impedance select switch, which lets you fine tune the mic pre for vintage tube and ribbon microphones. Channels 1 and 2 also provide the option of engaging a Mid/Side Decoder for M-S stereo mic’ing. Adjusting the balance between channels 1 and 2 with their gain controls provides an effective way to vary the width of the stereo image.

Channels 7 and 8 feature high-impedance instrument inputs so you can connect an acoustic, electric, or bass guitar directly to the mic preamp, eliminating the need for an external direct box.

Each channel has a mic/line switch, a polarity reverse switch, individual phantom power switch, low-cut filter switch, and a gain control.

A sample rate selector allows you to choose 32, 44.1, 48, 88.2, 96, 176.4, or 192 kHz sample rates, or to use an external clock connected to the external word clock input connector on the rear panel. You can also select between 24-bit or 16-bit dithered word lengths at the digital outputs.

The rear panel provides individual XLR balanced

mic input connectors for each channel, and balanced line inputs on a DB25 connector. Analog balanced line outputs are also provided on a DB25 connector. Digital outputs are provided on two optical Toslink connectors using the ADAT lightpipe digital audio format. AES/EBU or S/PDIF formats are available on a DB25 connector, with selection buttons for impedance, pro or consumer status bits, and single-wire (two-channel) or dual-wire (single-channel) operation.

THE GLOSSARY: A Haven of Non-Techiness for the Neophyte

The “Glossary of Terms” is a fairly comprehensive

dictionary of pro-audio terms. If terms like “clipping,” “noise floor,” or “unbalanced” leave you blank, refer to this glossary for a quick explanation.

ARCANE MYSTERIES ILLUMINATED

“Arcane Mysteries” discusses some of the down ‘n’ dirty practical realities of microphones, fixed installa- tions, grounding, and balanced versus unbalanced lines. It’s a goldmine for the neophyte, and even the seasoned pro might learn a thing or two.
