Manufacturer's Description from TK Audio

The BC1-S provides smooth buss compression associated with one of the most famous buss compressors from the mid 80's. Mixing engineers call it the magic "glue" when transparent compression strengthens mixes without compromising clarity. The BC1-S provides just that kind of compression bringing cohesion and punch; equally useful for drum buss and instrument compression. 

The built-in blend control makes it easy to apply parallel compression by adjusting the mix of dry and compressed signal. A mute-switch is provided for muting the dry signal making it possible to adjust the compression without changing the blend control. 

A switchable side-chain filter can be applied at 150Hz which makes the BC1-S less responsive to low frequency energy. The external side-chain input makes it possible to have the BC1-S pump to an external source. 

Smooth and transparent compression will never go out of fashion and the BC1 has already become a best-seller. The BC1-S will add the magic "glue" and make your mixes sound punchy and coherent.

To make it even more easy to work with we have now changed all potentiometers for detendet (stepped) controls for easier recall.

About Manufacturer

TK Audio is based in Halmstad, a small town in the southwest of Sweden. It started out in 2008 as an additional brand to Vintagedesign as we wanted to develop products with a bit more modern style. Thomas Kristiansson (or TK as his friends call him) is the mastermind behind both Vintagedesign and TK Audio and he has been working with electronics, cords and sounds in different kinds of professions his entire career.
Our philosophy is to produce creative audio solutions and assemble them in Sweden.
We buy the chassis from a local manufacturer and the main part of the panels is also produced nearby. Up until just recently we have assembled and soldered the circuit boards by ourselves but as the demand for our products has increased we can´t keep up so now we also use another company to help us out. They are situated just a 2 hour drive from Halmstad so we can still proudly say that our products are hand made in Sweden. We take responsibility for keeping our production as environmental friendly as possible and by having full control over the production and of course making all the final assembling by ourselves we can make sure that the quality always is top notch!
