TK Audio’s best-selling 500-series module, the BC501, is a stereo bus compressor that features all the power of TK Audio’s flagship BC1-THD. Since its release in 2015, it has found its way into a great number of 500 racks all around the globe. The BC501 is one of the most transparent stereo bus compressors ever made. The smooth, soft compression together with the blend control, high-pass filter, and the THD function are much-appreciated features that now have been expanded with the grab function, known from the BC1-THD. The grab function turns the threshold knee harder and makes the compressor even more perfect for the drum-bus. The BC501 is available in two versions, the BC501-GR with the standard stock black panel and the BC501-Ltd with a silver panel, individually numbered and limited edition of 100 units.
