The BC-4K is a highly versatile VCA-based dynamic range compressor, designed in the tradition of the classic console mix-bus compressors that defined the sound of the 1980s and beyond. The voltage controlled amplifier (VCA) circuit delivers precise, musical dynamic control with the responsiveness those legendary units were known for. Run it as a line-level device in the studio or as an instrument-level processor on your pedalboard. It gives you professional-grade compression wherever you need it.
