Analog Stereo Bus Compressor

If classic smooth bus compression is what you're after, then TK Audio's BC1-S stereo bus compressor is the tool you need. The recording engineers here at Sweetwater agree that when you need to "glue" a mix together, nothing does it quite like an analog outboard bus compressor. The BC1-S gives your signal transparent, clear compression, strengthening your mix with punch and unity. And it has a host of handy tools such as sidechain filtering, onboard wet/dry signal blending, and stepped knobs for easy recall of your settings. You owe yourself and your music a great piece of gear like TK Audio's BC1-S stereo bus compressor.

TK Audio BC1-S Stereo Bus Compressor at a Glance:
  • Great compression that doesn't kill your sound
  • Sidechain flexibility you need
  • Parallel compression capabilities with convenient features
Great compression that doesn't kill your sound

The BC1-S is what you need for fast, precise compression, whether it's on a single track or an entire bus. The stepped knobs give you precision control of threshold, ration, attack, and output gain. You can dial in unity and punch without giving up critical clarity.

Sidechain flexibility you need

The sidechain functions of the BC1-S give you the control and flexibility to build the sound you want. A switchable filter allows you to make the compressor less sensitive to frequencies under 150Hz. An external input specifically for sidechaining lets you set the BC1-S to feed an external source.

Parallel compression capabilities with convenient features

The built-in blend control on the BC1-S puts powerful parallel compression at your fingertips - now you can get just the right mix of dry signal and effected signal. The convenient dry signal mute switch lets you adjust the compression without changing your blend.

TK Audio BC1-S Stereo Bus Compressor Features:
  • Smooth VCA-based buss compression for cohesive mixes with exceptional clarity
  • Extended ratio, attack and release controls let you dial in just the right settings
  • Side-chain input and filtering give you flexibility
  • Blend control for parallel compression for the perfect mix
  • Single or dual side-chain detectors open up your mix options
It's not magic that glues together a great mix, it's you and the TK Audio BC1-S!

This is a magnificent secret weapon for bringing everything together, glueing everything together and if you love a great drum sound....shh...this will bring you nothing but that. Great piece of gear, built solid and looks elegant. Fantastic company!

Clean and Clear!

For the personal "acoustic" project recording that I do, the BC1-S is a great "set it and forget it" stereo VCA "glue-gun" that stays powered up on the 2 bus that I mix into. The BC1-S has replaced the Var-Mu as my primary mix bus compressor. I find the BC1-S pulls the mix together in a pleasingly clean and transparent way, where the Var-Mu in comparison colors the sound a tad too dark and thick for my personal preferences. To give up my TK Audio BC1-S, "you would have to pry it from my cold dead and calloused fingers.".- So go order your own!
