The TK Audio S-Blender is a mini mastering console with two stereo inserts for parallel / serial processing and a perfect tool for mixing and mastering. The five-step mode control changes the signal path, and numerous combinations can be tested without reconnecting any outboard. The first insert has a semi-fixed position and the second insert can be positioned at four different points in the signal path. At the push of a button the two inserts swap position and by using the mute buttons previewing can be done without altering the level controls. For easy integration the Blender has a separate monitor section with volume control and mono switch. It's the optimal unit for two-stage compression combining parallel and serial compression in a clean and simple way.
