Project Description

  • Three HPF frequencies
  • THD function that adds more even harmonics
  • Grab function that selects a harder threshold knee
  • Blend control for parallel compression
  • All controls stepped for easy recall
To celebrate TK Audio’s 10 year anniversary we are releasing the BC1Ltd in a limited edition of 100 pieces. We added some of the “most asked for” functions over the years like the THD function and HPF frequency options from the BC501. But we didn’t stop there, we also added an new function called “grab” that selects a harder threshold knee, perfect for the drum-bus.
The BC1Ltd panel is a sleek brushed anodized panel which gives an exclusive feeling and the units are individual numbered on the frontpanel.
