The Evolution of Recording and Mixing Consoles

The Evolution of Recording and Mixing Consoles

Recording and mixing consoles have changed a lot over the years, from tube-driven optical audio recording to compact 500 series modules and analog-emulation plug-ins. In this article, you’ll learn about the history and evolution of recording and mixing consoles, from the earliest Western Electric and RCA desks of the 1930s to the latest DAW control surfaces, and how digital recording revolutionized the entire industry.


Following the revolutionary release of “The Jazz Singer” in 1927—the first feature-length movie to use a synchronized pre-recorded music score and lip-synching, studios around the world began purchasing audio recording equipment for their motion picture productions. Western Electric and RCA made the first consoles and leased them to various studios. With locations in New York and Hollywood, both manufacturers specialized in sound recording for film. The first consoles used optical audio designs, vacuum tubes, and were based on designs found in broadcast, sound reinforcement and telephone equipment.


After the end of World War II in 1945, new technologies from Germany and other parts of Europe began to make their way to the United States. In contrast to the leasing business models of Western Electric and RCA, manufacturers like Ampex, Nagra, Rangertone and Fairchild were willing to sell their consoles directly to studios. With the continued growth of the audio console market, Western Electric and RCA remained two of the most popular suppliers for film sound recording equipment, until technology advanced in the 1970s.


The 1950s brought about some of the most significant changes since the introduction of the first consoles, as magnetic tape became the industry standard for recording audio. In 1958, EMI installed the first dedicated stereo mixing system, the REDD 17, at Abbey Road Studios in London. This was the exact, legendary console used by the Beatles and many more, and is often credited with establishing the concept of the large-format console still used today—with faders at the bottom and EQ controls for each channel above.

That same year, the Universal Audio 610 tube console was also invented, offering a ready-made desk for recording studios. As commercial consoles had yet to become commonplace, purchasing one of the earliest 610 desks often meant buying individual modules and building the console on your own. A few UA 610 consoles were actually built by Bill Putnam Sr. (the founder of Universal Audio) himself, and included a custom frame, power supply, metering and basic routing capabilities. Some of the biggest artists of the time purchased custom-built 610 desks to be built by Bill Putnam Sr., including Ray Charles and Frank Sinatra.


As technology progressed in the ‘60s, recording and mixing consoles began to switch from the tube-based designs of the 1950s to newer solid-state electronics. The older tube consoles offered a distinct tone compared to transistor-based designs. When pushed harder, tube-based audio gear generally produces a more rounded, smoother sound with pleasing harmonic distortion. This is part of the magic that makes tube gear popular so many years later. Transistor-based consoles allowed for smaller footprints that generated less heat and had lower power requirements. By 1964, Rupert Neve released the first-ever commercial solid-state recording console.

With solid-state condenser microphones growing in popularity during this time, console designers began to incorporate microphone powering capability into their mixers, which eliminated the need for outboard power supplies. During this era, consoles with up to 24 channels, like the famed TG12345, also became popular to accommodate 8-track recording devices. In 1967, the first operational amplifiers were used in professional audio gear, notably as summing devices for multichannel consoles.

The 1960s were a breakout decade for API. In 1967, API sold their first console to Apostolic Studios in New York City and followed up with the 2520 Discrete Circuit in 1968.  The 2520 is a proprietary op amp that’s at the heart of the legendary API sound in multiple products, including the 512 mic pre, 550A EQ, 525 compressor, 1604 console and more. Its hallmark is a tone that delivers focused mids, solid lows and classic ‘70s character. To close out a busy couple of years, the first 500 Series modules, including the 500 EQ, were first introduced in 1969.

If the ‘60s were considered a breakout period for API and Rupert Neve, the momentum continued into the 1970s with many popular recording and mixing console manufacturers debuting their consoles.

Although Neve was founded in 1961, it wasn’t until 1970 that the A88 console was released, which featured the legendary 1073 preamp and its trademark sound of rich lows, forward mid-range presence and pronounced, airy highs. Neve would also go on to release the first 80-series console, the 8078, in 1978.

SSL, founded in 1969, released the first A Series console and SL 4000 B in 1976. A total of two A Series consoles were made and sold before it was reinvented as the SL 4000 B. Six B Series consoles were built and this officially launched the beginning of SSL’s international business operations. By the end of the ‘70s, SSL released the legendary SL 4000 E Series, which would go on to be the foundation for some of the most popular recording consoles in the industry for the following two-plus decades. The 4000 E Series consoles featured a revolutionary Studio Computer and integrated display. It also had all the capabilities and features found in earlier 4000 desks, including an in-line channel strip layout, small faders, EQ/dynamics on every channel, computer-controlled automation and tape machine control.

Other manufacturers like Trident, MCI, Harrison and Datatronix would also go on to contribute to the rapidly evolving audio industry. The Trident A-Range desks were designed in 1972. The MCI JH-400 was also introduced in 1972, and boasted the first completely inline console design, inspired by Dave Harrison (who would later go on to found Harrison Consoles). In 1975, Harrison introduced the world’s first 32-bus in-line console, the 32 Series. In the world of modular audio, Datatronix released a 10-slot 500 Series rack for API and proprietary modules in 1978.

The SSL 4000 E Series, first introduced in 1979, went on to become one of the most popular consoles of the decade and is often credited with defining the sound of music during the 1980s. It delivered a classic big-console sound and its successor, the SSL 4000 G added additional mid-range punch that was great when working with vocals, drums or guitars.

In 1985, Rupert Neve founded Focusrite and debuted the acclaimed ISA line of transformer-based microphone preamps. That same year, AMS Neve (formerly the Rupert Neve Company) released the V Series console, with the first being installed at Yellow Two studios in Stockport, England, and the second installed at London’s AIR studios.  Neve desks are generally considered to have a warmer sound, though the earliest V series consoles are a polarizing topic among many audio engineers. By 1988, Neve released the VR console, which included its intuitive Recall software to store and recall settings.

In 1986, Yamaha released their first digital mixer, the DMP7. It was originally designed to be used as an onstage sub mixer to mix synthesizers and tone generators like the DX7, but Yamaha also equipped it with microphone inputs, offered expansion units and actively supported its use for PA systems and recording. As a digital mixer, the DMP7 offered some advanced functionality for the time, including automated, motorized faders and a memory function to recall mixer settings.


In the 1990s, the digital audio revolution began to take hold with the introduction of Sound Tools, the precursor to Pro Tools. It quickly became popular in commercial studios around the world.

As DAW (Digital Audio Workstation) software became the center of studio workflows for recording and mixing, DAW control surfaces began to rise in popularity. By 1998, the first Pro Tools controller, DigiDesign ProControl, was introduced. It featured eight motorized faders, a meter bridge and an array of hands-on controls that integrated seamlessly with Pro Tools. It made mixing in-the-box more feasible by bridging the flexibility of DAW software with physical faders, advanced automation and controls for AUX sends, mutes and plug-ins.


In the mid-2000s, home studios continued to become more common as computers became more powerful with each passing year. With the DAW firmly established as the core of most studios, many engineers and enthusiasts began to look for ways to bring analog vibes to their digital recordings. As a result, 500 Series modules began to grow in popularity, with more manufacturers jumping into the fray, including acclaimed brands like Neve and SSL.

By the late 2000s, analog emulation plug-ins had advanced to the point of being able to rival the sound of outboard hardware analog gear. The Universal Audio UAD platform, for example, is an industry-leading ecosystem of plug-ins and DSP acceleration that delivers authentic analog sound—from tube compressors and equalizers to vintage reverbs and tape machines. The Universal Audio DSP has become so powerful that UAD plug-ins are widely considered to be the gold standard for analog emulation in the digital realm.
