Vari-Mu Compressor OmniTec-436C

A brief history

Our latest vintage vari-mu compressor plug-in draws inspiration from the legendary Altec 436C tube compressor, renowned for its dynamic range and vintage warmth. Originally introduced in the 1950s, the 436C was quickly embraced by top producers for its versatile parametrization and its highly musical output. This iconic compressor's innovative circuit and distinctive sound went on to inspire other famous compressors, including the Fairchild and Manley vari-mu units.

This iconic piece of gear has a long list of impressive credits, such as legendary producer Geoff Emerick of Abbey Road Studios. He made use of the Altec 436C to lay the groundwork for many hugely significant recordings, including those of The Beatles, Herb Albert, and Frank Sinatra. The 436C then went on to establish itself in pop music studios across the US and Europe.

The OmniTec-436C plug-in flawlessly emulates the best features of this vintage compressor while modernizing them with our signature Black Rooster Audio twist; offering additional side chain filters, a dual mono/stereo link, limit mode and SC listen mode.

With its tube-based modeling, the OmniTec-436C has a highly musical quality that brings a smooth, mellow tone to your tracks, without ever overpowering a mix. Instead, it provides just the right amount of cohesion, giving your recordings the perfect amount of "glue."

The OmniTec-436C is the perfect tool to add that luscious vintage tone to your mix. Try it on vocals, strings, brass, or even synthesizers, and experience the vintage quality that stands the test of time.

OmniTec-436C Vintage Compressor Plug-in Frontplate

"On master bus, the 436C is capable to gently compress and even out the sound before feeding it into the final limiter. It preserves the low end, can give it extra punch or tame those unnecessary heavy low end sparks. It is also highly usable on vocals, thanx to its transparent compression - it feels like the vocals keep their natural dynamic range while being more audible through the mix."
