TK Audio BC1THD

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.

• Threshold: -20dB to +20dB

• HP Filter: 80Hz, 150Hz, 220Hz, -6dB octave

• THD: adds more even harmonics

• Grab: selects a harder thres hold knee
