Harrison Audio may not get as much buzz as some of the other classic console brands, but they’ve been a major player in the industry for about half a century. By developing innovative technologies, adapting to industry changes, and diversifying the brand's product line; Dave Harrison and company have established themselves as a top choice for music and post-production studios while maintaining a presence in the live and broadcast sectors and even breaking into the software market with the brand's Mixbus DAW and plug-ins.

Explore Harrison Audio’s history, starting from its beginnings in the golden age of analog recording, through the rapid evolution of digital audio, and into the present day.

The Early Years

Founder Dave Harrison started off as a saxophonist and recording engineer in the Cincinnati, Ohio area before working his way up to Manager at King Records, an iconic Cincinnati studio used by A-list entertainers including James Brown, John Lee Hooker, and The Platters. Eventually, Harrison moved to Nashville, Tennessee and started Studio Supply, a recording studio building and outfitting company. 

Studio Supply was a reseller for MCI, one of the most prominent manufacturers of cutting-edge multitrack recorders at the time. In the early 1970s, Harrison approached MCI founder Jeep Harned with an idea for a new “in-line” console design that would seamlessly integrate the recording and mixing workflows.

This collaboration resulted in the MCI JH-400, the first commercially produced in-line console. Harrison also had ideas for remote-controlled gain and switching systems, but MCI was not interested at the time, so he founded his own company to bring his products to market.

Over the years to come, Harrison consoles would be used to make some of the most iconic records ever made, from Michael Jackson's Thriller to Nirvana's Nevermind and beyond.

1975

Harrison Audio makes its debut with 32-Series in-line consoles

Dave Harrison’s first original console, the Harrison 3232, perfected his version of the in-line design, which combined the previously separate recording and monitoring signal paths into each channel strip. Compared to existing consoles that required twice the amount of channels to record and monitor simultaneously, the 3232 streamlined the mixing process while saving precious space in the control room.

After the smashing success of the Harrison 32-Series, other manufacturers followed suit and the in-line design became the de facto standard for multitrack recording consoles.

Innovating in a Changing Industry

As digital audio advanced by leaps and bounds, the 1990s and early 2000s brought significant changes to the music and post-production industries. Analog audio formats moved toward obsolescence, home recording technology became more and more affordable, and the bottom fell out of the music industry, causing many studios and record labels to fold. But Harrison Audio continued to thrive, releasing some of the brand's most celebrated consoles during this time, winning prestigious industry awards for the brand's innovation, and eventually stepping into the software market with a custom DAW.

1991

1992

First Harrison Motion Picture Console installed at Sony Pictures

On Valentine’s Day 1992, Sony Pictures installed the first Harrison Motion Picture Console (MPC), kicking off a legacy that continues to this day with the Harrison MPC5. Designed in close collaboration with post-production experts including Sony Pictures Chief Engineer Jeff Taylor, the massive MPC was built for multi-user mixing workflows and featured motorized joysticks for automated surround panning.

1994 

Harrison introduces SeriesTwelve console

Five years after the SeriesTenB became a studio favorite, Harrison followed up with the next-generation SeriesTwelve. This model completely separated the all-digital control surface from the analog processing racks, drastically reducing the console’s footprint.

The modular control surface allowed up to four “layers” of channels to be assigned across the desk, making it endlessly reconfigurable for complex music, film, or broadcast workflows. Powered by an Apple NuBus computer system, the SeriesTwelve featured a touchscreen interface and shared central panel that allowed the user to process any channel without moving out of the “sweet spot.”

1999

Harrison Live Performance Console honored with TEC award

Harrison capped off the millennium with another TEC Award, this time recognizing the brand's Outstanding Technical Achievement in Sound Reinforcement Console Technology with the Live Performance Console (LPC). Jointly developed with tour sound company ShowCo, The LPC brought Harrison’s digitally-controlled analog technology to the live sound market in 1998.

The console featured stage-mounted audio processing racks that drastically reduced cable runs and a new IKIS automation system with instantly recallable “scenes.” ShowCo continued to use LPC consoles for the next two decades, including tours with high-profile acts such as Madonna and U2.

2004

Harrison Audio develops new Xrange audio processing system

Over a three-year research and development period, Harrison engineers created Xrange: a Linux-based, 64-bit audio processing system to power the brand's new generation of consoles and provide a futureproof platform for future upgrades. Xrange technology was first deployed in the Harrison Air24 broadcast console.

2005

Universal Studios installs Harrison MPC4-D film console

As post-production demands for major studio films grew increasingly complex, Harrison adapted with the MPC4-D: a massive, 30-foot console designed for three simultaneous users (typically a dialogue mixer, a sound effects mixer, and a music mixer). The Xrange-powered system featured a total of 384 channels—each with two inputs, an eight-band EQ, dynamics processing, and Harrison Digital Tools DSP effects.

Harrison Audio introduces Trion digital console

The Harrison Trion followed in the footsteps of the reconfigurable SeriesTwelve consoles, taking advantage of modern manufacturing techniques to offer maximum flexibility at a reduced cost. The Trion’s hardware and software could be reconfigured to suit the needs of recording and mixing studios, live and broadcast applications, post-production studios, and more.

2009

Harrison Audio launches Mixbus DAW

As digital recording technology flourished in the new millennium, Harrison seized the opportunity to enter the market with a custom digital audio workstation (DAW) software. Based on the open-source Ardour DAW, Mixbus provides all of the standard recording, editing, and mixing features with a Harrison-style mixer interface featuring the brand's signature EQ, compressors, limiters, analog saturation characteristics, and even meters based on real Harrison consoles.

Branching further into the software market, Harrison created the AVA plug-in range to make its most popular audio processing tools available to engineers working in any DAW. The first offering was the AVA LegacyQ (now Legacy EQ), which emulated Harrison’s famous digitally-controlled analog console EQs. Today, AVA is just one of Harrison’s four plug-in collections, including the Studio, Post, and XT lines.

2019

Harrison Audio introduces MPC Channel Strip plug-in 

With channel strip plug-ins becoming a popular all-purpose tool for in-the-box mixing, Harrison decided to recreate the beloved Motion Picture Console in plug-in form. The MPC Channel Strip combines six essential processors for post-production work in a reconfigurable window with custom layouts for popular control surfaces.
