Mix Bus Compressor

The Bus Compressor is based on the mix bus VCA type compressor of a worldwide known   acknowledged British large format mixing console from the 80`s. It was used on practically every hit record   major production from the 80`s to present days, so much that its sound has almost become a trademark. This compressor was so widely used that it later become a stand-alone rackmount unit, so that it could be used separately from the large format console. This made for even more success, a thing that led to many hardware   software clones trying to emualte it.
This legendary processor has been painstakingly analyzed   measured down to the very single component, compression curve, soft knee behavior   detection circuit; this in order to obtain a dead on reproduction that will impart a cohesiveness to mixes that is often referred to as "glue effect" where every instrument blends nicely with the others,   mixed tracks suddenly start to sound like "music".
Like many of our hardware based modules we`ve added several nice   handy features not present on the original; in this case we added the "Grit" switch that will reproduce the slightly increased 2nd harmonic distortion of an out of calibration unit, a behavior favored by many engineers for its more charcterful sound.
The Sidechain HP filter has been added to filter low frequencies out of the detection circuit path so that they wont overmodulate compression, thus avoiding the "pumping" effect at lower threshold   higher ratios. When not engaged though the “pumping” effect delivered by this module is astonishing, making it eqaully at home on loud rock mixes   slamming dance tracks.
The 1.5:1 ratio has been added for subtle   even compression making mixes "shine" without sounding compressed.

We like to see it sitting on the mix buss of your DAW, where it was ideally designed to be, but it also rules on other stereo sources, like drums submixes   parallel compression buses: this use is also well known to engineers   producers the world over, a very effective for “obscene” amounts of compression, punching   pumping drum rooms   creative effects.
