The Warm Audio BUS-COMP is a two-channel stereo VCA compressor, inspired by classic circuits which for decades have produced a soft, velvety sound. Stereo VCA compressors perfectly control the dynamics on many sources, but they mainly owe their recognition to their magic touch on stereo mixes. The BUS-COMP will work perfectly on stereo mixes, drum buses, overheads, acoustic guitars, keyboards, pianos, orchestral instruments, voiceovers. The BUS-COMP is mainly designed to operate in stereo, but it can also be effective on individual mono sources. VCA compressors of this type have become popular for their ability to control dynamics effortlessly but also to add depth and color to the audio signal, even when no compression is applied. Recreating compressor technology at VCA was central to the design of the BUS-COMP, however, adding options and improvements was also important during its development. One of the characteristics of the BUS-COMP is to have transformers made in the USA by CineMag in the signal path, amplified by fully discrete op-amps. With a simple press of the button on the front, these custom transformers made in the USA are inserted in the signal path, increasing the depth and the grain of the sound.
