TK Audio BC1-THD

The BC1-THD provides smooth bus compression that applies for both mixing and tracking.
Engineers call it “The Magic Glue” when the BC1-THD’s transparent compression strengthens mixes without compromising clarity.
The built-in blend control makes it easy to apply parallel compression by adjusting the blend of dry and compressed signal. A switchable sidechain filter can be applied which makes the BC1-THD less responsive to low frequency energy. The THD function adds more harmonics to the signal and the “grab” mode selects a harder threshold knee on all four ratio settings. Smooth and transparent compression will never go out of fashion.
