Harrison Audio Consoles

Harrison Audio Consoles is an international company based in Nashville, Tennessee that manufactures high-end mixing consoles, Digital Audio Workstations (DAW), audio plugins, and other audio technologies for the post-production, video production, broadcast, sound reinforcement and music recording industries.  The company is renowned as an industry innovation for its "in-line" mixing console design that has subsequently become the standard for nearly every large-format music console.  Over 1,500 Harrison consoles have been installed worldwide, presenting a significant percentage of the overall world market share for high-end audio consoles.  The company founder, Dave Harrison, was inducted as a Fellow in the Audio Engineering Society for this technical contribution of the recording industry and in particular the first 32-bus "in-line" console.

History

Harrison came to the recording industry after working for 5 years in recording equipment retail. In the early 1970s he acquired a dealership for Music Center Incorporated, then a manufacturer of tape recorder and record electronics equipment. In 1972 he approached company CEO Jeep Harned with a concept for an in-line mixing console that simplified the incorporation of multitrack recorders into a console signal path. The Harrison-designed MCI  JH400 series console was the world's first commercially available in-line console. Realising the importance of his innovation to multitrack production in both the recording and film industries, Harrison established the manufacturing company, Harrison Consoles.

During the first decade of its existence, Harrison Consoles produced a series of popular consoles for the film, music, broadcast TV markets.   In 1975 the company introduced its first product, the Harrison 3232, and the first 32 series product. This was followed by the PP-1 film console, the MR-2, MR-3, and MR-4 music recording consoles, the TV-3, TV-4 broadcast consoles, the HM-5 live console, the Raven music recording console, and the Air-7/Pro-7 broadcast and production consoles.  These fully analog console designs continued into the 1990s, while the digital revolution was taking place.  During this period of rapid digital development, Harrison still continued to produce analog consoles (often with some digital elements) such as the AIR 790/PRO 790 broadcast and production consoles, AP-100 on-air production console, the MR-20 music console, the industry workhorse TV-950 and Pro-950 production consoles, and finally the TV5.1 surround-capable broadcast console.

In 1985 Harrison introduced its SeriesTen, the world's first digitally controlled analog mixer with console automation.  The SeriesTen used only 3 knobs above each channel strip to "page" between various functions of the console.  By separating the knob from the actual audio signal, it was possible to instantly save and recall the settings of the console, without mechanically turning the knobs on the surface.  At the time this was unheard of, but it has now become a ubiquitous feature of every digital console on the market.  Perhaps proving that the SeriesTen was ahead of its time, many SeriesTen console were still in use in 2009.

ABBA produced all their hits on their Harrison console at Polar Studios.  The a capella introduction to Kansas' Carry On Wayward Son was recorded from Harrison console preamps directly to tape.  Throughout the 1980s, seminal music works were mixed on Harrison consoles: Michael Jackson's Thriller and Bad albums were both mixed on a Harrison console by Bruce Swedien. Janet Jackson's Rhythm Nation was mixed on a Harrison SeriesTen,  And Sade's album Promise and her prior hit song Smooth Operator were recorded and mixed on a Harrison console.

In 1989 Harrison Systems was acquired by GLW Incorporated.  GLW's first product introduction was the release of the SeriesTenB, an updated version of the SeriesTen utilizing a powerful Mac-based automation system coupled with new video interactive graphics for display of console information and the control of console functions through the use of an interactive video screen. The company's technological advances accelerated in the 1990s as additional resources were dedicated to research and development. The first fruits of these efforts was the introduction in 1992 of the fully automated Harrison MPC (Motion Picture Console) followed shortly thereafter by the debut of its sister console, the fully automated Harrison SeriesTwelve.

The Series10 technology was advanced in a follow-up product for film, the MPC.  The MPC was a control surface that remotely controlled the audio processing racks.  This separation of the control surface from the audio racks allowed the audio processing racks to be placed in the machine rooms, thus allowing for sleeker, cooler, and more acoustic-friendly control surface designs tailored to fit the needs and applications of each individual user.  Additional technologies such as automated, motorized joysticks and advanced monitoring features were also incorporated into the MPC.

The Harrison SeriesTenB with its new automation system and interactive video graphics was recipient in 1991 of the coveted Mix Foundation Technical Achievements Award for Console Technology, the TEC Award. Shortly thereafter, the first MPC was installed at Sony Pictures in Hollywood in 1992, the first truly fully automated large format film re-recording console. The MPC was designed in a tight collaboration with Jeff Taylor, chief engineer at Sony Pictures, and many film and post-production mixers. The ongoing relationship between Harrison and Sony Pictures Post Production Facilities in Hollywood has resulted in the purchase of thirteen massive, fully automated MPC consoles by Sony.

During the late 1990s there was a clear demand for a digital processing engine which could satisfy the need for increased channel counts that were becoming possible with new digital production techniques.  Harrison developed the digital. engine, a powerful DSP mixing and routing engine that could provide 768 fully resourced channels and thousands of input and output signals.  The digital. engine was designed to retrofit existing analog MPC or Series12 consoles with a new digital backend.  Many Harrison customer upgraded their existing consoles to the new engine because it was cost effective and did not incur the "down time" of replacing an entire console.

Harrison continued its technological advancements and was awarded another TEC Award in 1999, this time for Outstanding Technical Achievement in Sound Reinforcement Console Technology. This award was granted to the Harrison LPC (Live Performance Console). The LPC console was co-developed with touring sound company Showco to create a no-compromise sound reinforcement console. Taking advantage of Harrison's digitally controlled-analog technology, and a newly developed IKIS automation engine, the LPC was designed with motorized potentiometers for every console parameter.  Similar to Harrison's motorized joysticks, the motorized potentiometers allowed the user of the console to work in an intuitive way, while providing all the benefits of digital surfaces such as instant recall.

In 2000, Harrison was awarded a patent for their use of automated, motorized panning joysticks.  This technology has been licensed to other console manufacturers.

During the early 2000s, increasingly complicated audio productions drove the adoption of TFT screens into the meter bridges of digital consoles.  Harrison developed linux-based TFT screens that simultaneously show EQ curves, panning, auxes, metering, bus assignments and dynamics.  In addition, a new PreView waveform technology was developed for the screens.  This technology allows users to see cues before and after they happen, much like the waveform views on a workstation.  This feature was incorporated into the MPC4-D.  The MPC4-D has been adopted by premiere film dubbing stages around the world, such as Universal Studios (Hollywood), CinePostproduction (Munich), MosFilm (Moscow), Shree Balaji (Mumbai), and Deluxe (Toronto).

Many international blockbuster films have been mixed on Harrison Consoles: Transformers 1 and 2, Spider-Man 1 through 3, Jurassic Park, Pearl Harbor, Harry Potter, The Passion of the Christ and Amélie are some examples.  Television shows The Simpsons, 24, and CSI are mixed on a Harrison console.

In 2004, a new cost-effective version of the Series12 multi-purpose console surface was developed: the Trion. The Trion uses Universal Serial Bus (USB) connectivity and other non-proprietary hardware. The Air24 was also developed using the same technology for on-air radio broadcast.  The new smaller surfaces needed a smaller processing engine, so the Xrange native processing system was developed for use in all Harrison products.  The Xrange uses Linux and off-the-shelf computers instead of the proprietary systems common to previous-generation consoles.  A Harrison console system is made up by the combination of an application-specific console surface (MPC, Trion or Air24), along with a processing engine (Xrange), and an automation computer (IKIS).  Each of the three pieces (surface, processing, and automation) are updated regularly by Harrison to accommodate new technologies.

Harrison has adopted Linux as the underlying technology for all of their products.  The automation system, console surfaces, DSP processing, and audio routing all incorporate Linux at some level.  Harrison has also collaborated with open-source developers on their Xdubber and Harrison Mixbus products which is based on the Ardour open-source workstation.
