Recording studios often use rackmount "vocal channels," namely a mic preamp, compressor, and EQ all in one unit as a front end for vocal recording. The Diamond Compressor is Diamond's take on a guitar channel: a dynamics and tone shaping tool for live and studio use, with low-noise, ultra-linear signal buffering, smooth opto-based compression, and a versatile 'tilt' EQ that musically shifts overall frequency balance. All in a user-friendly 3-control package - just Comp, EQ and Volume.
