Bus Compression for Today's Hybrid Studio In designing the 7721 Stereo VCA compressor, the engineers at Chameleon Labs began with a clean slate to develop a bus compressor for today's hybrid studio. Basing detection on a voltage control amplifier (VCA), and designing a circuit that provides low noise and transparency, the team created a device that does an excellent job of gluing your mixes together while delivering that elusive punch and perceived loudness that makes a mix blast out of the speakers. Enhanced control set The Chameleon Labs 7721 gives you an enhanced control set with all the classic settings in addition to controls usually found only on esoteric compressors. Soft/Hard Knee lets you switch between a gentler compression onset and a faster onset more akin to limiting. Peak/RMS Detection lets you switch between Peak and RMS detection schemes that behave quite differently. Peak detection engages compression by monitoring instantaneous
