TK Audio BC501 500-Series Stereo Bus Compressor
The TK Audio BC501 500-Series Stereo Bus Compressor is a stereo bus compressor that features all the power of TK’s flagship BC1-S.
The new BC501 adds some more functions taken from the BC2-ME mastering compressor, such as additional ratio settings (1.25:1, 6:1), a THD switch that adds more even harmonics to the signal, and three HPF settings from which to choose (80Hz, 150Hz, 220Hz). All controls are stepped for easy, precise recall. A dedicated Dry/Comp knob allows blending between the original and compressed signals, and an external sidechain input (accessible via stereo 1/8″ mini TRS jack) is also provided.

What We Think
The TK Audio BC501 500-Series Stereo Bus Compressor comes off in the vein of a loved buss comp (from a well known British console). The BC501 is a relatively natural sounding comp, with a slight bit of pleasing roundness (or maybe a slight softness) to it. The more you push it, you will hear it get a little thick and punchy, but it is never over the top. You can get it to tighten things up very well, and add an overall glue to a mix or drum buss. Add in the THD feature and you can add a nice attitude that pushes the sound in a fun direction. I really liked that for rock and rap (more up beat and energetic music). More than anything else though, I love the blend knob. Being able to do parallel compression at the unit makes this comp nicely flexible.

One of the best purchases I've made. This is the 500 series of a compressor called the magic glue for a reason. The sound is phenomenal and I'm not into exaggerating when it comes to gear. It can go from smooth to aggressive and yet still sound musical. There is a lot of control over the sound and I even use across the 2 bus during mix downs. A purchase you won't regret at a price that's well worth it.
