The Peavey Kosmos Pro Enhancer is an expanded version of the original Kosmos subharmonic and stereo image enhancement system. It's been updated with +4dB electronically balanced XLR I/Os and S/PDIF digital I/O. This professional all-analog unit gives you control over 4 processes: Quake, a subharmonic synthesizer; Thud, a low-frequency "sculpting" tool; Xpanse, a high-frequency and stereo image enhancer; and Stratos, a dynamic HF effect.

Front-panel controls include global bypass, a switchable LED meter, and 2 input/output level pots, each of which provide up to 10dB of extra output.
