Warm Audio Bus-Comp Analog VCA Compressor

Add the magic of analog stereo compression to your mixes and busses. The Warm Audio Bus-Comp is based on classic VCA circuitry for a smooth, reactive sound.

The Warm Audio BUS-COMP is an all-analog, 2-channel, stereo VCA compressor based on classic circuitry that has provided silky smooth tone for decades. Stereo VCA compressors are masterful at controlling dynamics on many sources, but they have become widely known for their magic touch on stereo mixes.

The BUS-COMP will perform well on stereo mixes, drum mixes, drum overheads, acoustic guitars, keyboards, piano, orchestral instruments, voice-overs and an array of other sources. The BUS-COMP is primarily designed for stereo use, but it can be used just as successfully on individual mono sources. VCA compressors of this type have become widely loved for their ability to control dynamics effortlessly but also for the added tone and depth they provide to the audio signal that passes through them, even when no compression is applied.

Re-creating legendary VCA compressor technology was the focus of the BUS-COMP's design, however, adding options and improvements was just as important during its development. One of these added features is the BUS-COMP's ability to have USA made CineMag transformers inserted into the signal path driven by fully discrete operational amplifiers. With a single push of a front panel switch, these custom USA made transformers are inserted into the audio path providing increased depth, tone and vibe!

The sound is perfect, I use this on my main out bus, I planned mixing directly through into another sound interface or back into the main interface. All plug-ins sound real and amazing. It almost made me say I'm completely, it's that good. If your digital tracks not cutting it with radio or other big studios, this is the golden missing link. Perfect.However my only gripes are is way cleaner than a SSL G bus in my opinion, and it takes a little push to get meter moving, but gets a little dirty then. Stop hesitating and Buy it. Welcome to the big leagues.
