Introducing : The Motown EQ

A Piece of Recording History

In the continuing effort to faithfully recreate classic Motown audio products for today’s recording studios, Acme Audio is proud to announce the highly anticipated release of our Motown EQ. An absolute legend among audio engineers and producers, only 48 of the original Motown EQs were ever produced – and it’s considered one of Chief Engineer Mike McLean’s pinnacle achievements at Motown Studios. With its transformer balance audio path and gain makeup amplifier section, this 7-band graphic equalizer was a vast improvement to the products that were commercially available in the Motown era. Acme Audio had the honor of spending several weeks with the late Mike McLean reverse engineering an original Motown EQ and had his ongoing guidance to faithfully recreate and reintroduce this classic piece of equipment to the recording world. No components were compromised in this reproduction… every inductor, capacitor, and transformer was either sourced from original manufacturers or painstakingly recreated to match the performance and sonic quality of the original Motown EQ. In essence, this is the closest you will ever come to owning this essential piece of recording history.

The MTP-66

The Motown Tube Preamp

The year is 1966. Deep in the heart and soul of Detroit, a young, ambitious chief Motown engineer is tasked by legendary producer Berry Gordy to design a better way to record multiple guitar and bass instruments at once, with minimal bleed and no isolation.  His solution:  the 5-channel Motown input box – dubbed the “Motown guitar amp” by its creator.  James Jamerson’s magnificent performances, as well as Dennis Coffey, Bob Babbit, Robert White, Joe Messina and many more, were captured through this circuit from 1966 to 1972, and now, the MTP-66 Motown Tube Preamp is available now from all our dealers.

Newest in the series of Acme Audio Manufacturing’s line of faithful recreations of legendary Motown gear, this single-channel lunchbox preamp has been exactingly reborn using the original 1966 engineering schematics, and features an all-tube signal path, with hand selected tubes that drive a Cinamag output transformer.  Besides being an instrument-to-line-level all-tube preamp, Acme Audio has added a microphone amp section that is also based on Motown Engineering’s original designs, featuring a fixed gain pentode with the Acme Audio/Triad input transformer. Other key features include adjustable input and output controls (not made available on the original,) giving you the ability to adjust your sound to the desired amount of drive and compression.

Motown D.I.

The Detroit Sound

During Motown’s heyday, a major technical component of “The Detroit Sound’ was the direct input box (DI). Designed by a young Motown audio engineer in the early 1960s, the musicians plugged straight in and achieved a distinct, colorful distortion that would become recognizable all over the world. The DI box was adopted by such Motown greats as James Jamerson Sr., Dennis Coffey and Bob Babbitt, who defined the sound of a generation with their soulful playing and crisply captured notes.

Recreated by Acme Audio, the new Motown D.I. WB-3 brings the exact character as the original DI box. Modern updates include the improved variable attenuated for high-level input and the custom-made, rugged steel case (the original DIs were built in Aluminum boxes). Owners of the Motown DI will find that it increases sound quality in a marginal acoustic environment, for the cleanest, purest sound source possible.

The Opticom XLA-3 MKIII

Acme Audio’s flagship all-tube optical limiter

The Opticom XLA-3 is an all-tube optical limiter inspired by the classic Teletronix LA2A. Loving the la2a’s smooth natural compression characteristics but seeking to improve upon its single compression speed inspired us to develop the XLA-3. The heart of the XLA-3 is a unique triple optoelectronic circuit that combines the best characteristics of 3 separate compression curves into a single unit. The result: a high-speed optical limiter with tones that range from ‘clean’ to ‘harmonically rich’ to ‘dirty.’

The Opticom XLA-3 plugin

The sound of the legendary Acme Opticom, in a plugin!

The Acme Opticom XLA-3 is a powerful and flexible optical compressor with glorious tube-powered, triple optoelectric, cold-rolled steel covered military-grade componentry. Slap it across the drum buss for solid and seamless LA-2A styled leveling. Force vocals through the input to add grit and attitude to a wimpy take. Use Amp mode to add harmonic color to a guitar or bass line without even touching the dynamics. The Opticom XLA-3 is a bombproof beast of an optical compressor, and thanks to Acme’s cooperation with Brainworx, it’s now available in plugin form to tame and/or soothe any sound you throw at it.

The original XLA-3 hardware features three compression responses that each treats sounds in a totally different way, affecting spectral regions with varying envelope behaviors and distortion characteristics. On top of that, an Amp mode allows for gain boosting without dynamics reduction. Whether using the Fast, Normal or Slow setting, optical CdSe (Cadmium Selenide) photocells will always leak a perfect little Videotransient through while allowing you to smash sounds to oblivion, or simply tame your peaks. Brainworx faithfully emulated the XLA-3 and captured these features in plugin form, right down to the Light History behavior exhibited by light-dependent resistors when returning from a resting state, or being constantly assaulted with input. Additionally, several new features were added to the plugin version, including a parallel mix knob, an output trim control, and an adjustable noise floor. All of the complex and sonically beautiful behavior has been faithfully rendered in the plugin version.

The Acme Opticom XLA-3 is the simple solution for powerful optical compression and harmonic coloration. Drive the input. Set the behavior. Level to taste. Done.

Opticom XLA-500

Taking inspiration from the acclaimed XLA-3, Acme Audio has painstakingly squeezed the XLA-3’s topology into a convenient two space 500 series module.

Acme Audio Mfg. Co. is proud to introduce the OPTICOM XLA-500.   Taking inspiration from the acclaimed XLA-3, Acme Audio has painstakingly squeezed the XLA-3’s topology into a convenient two space 500 series module.  The XLA-500 is a tube optical audio limiter designed to produce a full range of non-linear, dynamic audio effects.

The heart of the XLA-500 is a unique triple optoelectronic circuit that combines the best characteristics of three separate compression curves into a single unit. Combined with Cinemag input and output transformer and a class-A gain stage,  the result is a high-speed optical limiter with tones that range from ‘clean’ to ‘harmonically rich’ to ‘dirty’; and compression curves that range from subtle and slow to very fast and aggressive.

The Opticom XLA-500 is the most versatile 500 series optical limiter on the market.  Whether trying to gently control dynamic range on vocals, adding weight to a bass track, or even crushing a drum track – the XLA-500 can perform all of these tasks effortlessly and with great satisfaction to the user, and, ultimately, to the listener.
