CHANNEL STRIP
Mackie has combined the premium sound quality of the Onyx mic preamp and Perkins EQ with an extensive professional feature set. This intuitive, ergonomic layout creates the most flexible channel strip in this class of mixer.

Onyx Mic Preamplifiers
Mackie’s flagship mic preamplifiers feature individual 48V phantom power (with indicator), mic/line switch, 100Hz High Pass filter, and polarity inversion providing exceptional fidelity and professional functionality.
Perkins EQ
When it was time for the Onyx EQ section, we turned to veteran audio engineer Cal Perkins to develop our new Perkins EQ circuitry—a "neo classic" 4-band design based on classic "British EQ" circuitry from mixing desks of the '60s and '70s. Cal devised a way to give Perkins EQ that sweet "British console" sound, but with greater filter control and minimum phase shift.
Stereo Linkable Auxiliary Sends
Mackie’s latest groundbreaking design incorporates 8 auxiliary sends logically divided into pairs. Each pair of sends can be designated as pre- or post-fader. Plus every pair has a Stereo button that reconfigures two potentiometers to perform level and pan functions for simple and intuitive control of up to four stereo In Ear Monitoring (IEM) mixes.
Mute Groups
Four mute group switches on every channel allow for fast and simple assignment of channels to any and all of the mute groups. Mute Group master controls are accessed in the Master Section for lightning fast activation/deactivation of the groups.
Channel Master Section
Each channel comes equipped with a 100mm faders for smooth, high-resolution control of your mix. A four-segment input meter right next to the fader instantly provides an expanded view of signal level—far superior to the typical signal/peak LEDs found on most consoles. Mute and Solo buttons with indicators are positioned above and below the fader to ensure functional separation.
MASTER SECTION
Mackie’s Onyx 80 Series Master section provides everything you’d expect from a professional full-size mixing console, and more. Designed with a practical and easy-to-understand layout, everyone from the Sunday School teacher, to the highly experienced mix engineer can quickly learn the console and fully exploit its outstanding flexibility.

Stereo Auxiliary Input Channels
These eight "hybrid" channels provide ample stereo inputs for all your outboard effects returns and stereo playback devices, and ensure that you will never be forced to chew up valuable microphone input channels. And every Stereo Aux input includes a 4-band fixed Perkins EQ, 4-segment input meter, 60mm fader, Mute, PFL Solo, and exceptionally flexible routing to the Aux sends, Groups 7-8 and Main Outputs.
Aux Masters
Eight Aux Masters provide level control, Mute and AFL Solo for each output. Master control knobs are color coded to match the channel Aux send controls and make locating them fast and simple.
Aux/Group Flip
Functions associated with each set of Aux Master and Group controls can individually be flipped via these convenient buttons with LED indicators. Perfect for simultaneous FOH/Monitor applications, these switches allow the Aux masters to be controlled via the 100mm faders and associated 4 segment meters.
Group Control
Eight 100mm Panasonic® faders provide smooth and accurate control of Group levels. A 4-segment input meter located next to each fader instantly provides detailed signal level information. Mute and AFL Solo buttons with LEDs, plus Main Mix assignment and Group Pan controls round out the section to give you quick access to all the control you need.
Main/Solo Meters
Two large, 12-segment LED meters for Left and Right Main Outputs plus two additional 12-segment meters dedicated to PFL/AFL solo levels provide clear indication of primary signal levels. Two Green and Amber "Rude Solo" LEDs flash to indicate currently AFL and/or PFL soloed channels.
10x2 Matrix
Two extra independent mixes built from the Subgroups and Main Outputs for recording, zone outputs, hearing assistance systems, additional aux sends, etc.
Masters and Utilities
Master switches for the four Mute Groups, Talkback system with extensive routing, Mono Main Output control with Solo, Headphone and Monitor Output control, and separate 100mm Panasonic® faders for the Left and Right Main Outputs provide convenient access to all necessary functions.
