TK Audio BC501-GR 500 Series Stereo Compressor

500 Series compressor BC501-GR is a stereo bus compressor equipped with virtually all the features found in the large TK flagship BC1-THD. The BC501-GR adds a few extra features taken from the BC2-ME mastering compressor, such as extra ratios, a THD switch that adds harmonic distortion to the signal, and three HPF settings (80 Hz, 150 Hz, 220 Hz). All controls are “stepped” for easy and accurate recall. A dedicated Dry/Comp control allows mixing between the dry and compressed signal, and an external side-chain input (accessible via stereo 1/8″ mini TRS jack) provides additional options.
