TK Audio introduces the BC501-GR and BC501-Ltd 500-Series Stereo Bus Compressor

Introducing the BC501-GR & BC501-Ltd 500-Series Stereo Bus Compressor. Since the BC501 was released in 2015 it has found its way into a great numbers of 500 racks all around the globe and now the new updated BC501 is here!

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 will be released in two versions right from the start; the BC501-GR with the standard stock black panel and the BC501-Ltd with silver panel, individually numbered and limited edition of 100. The look of the panel is the difference between them; all functions and price are the same.

The BC501 is one of the most transparent stereo bus compressors ever made. It’s manufactured and assembled in Sweden and thoroughly tested before leaving the factory.

Key Features:

  • External sidechain input via a stereo 3.5mm TRS (unbalanced stereo)
  • THD circuit that adds even harmonics
