The Hush Pro features a noise gate and Rocktron’s patented HUSH noise reduction system, which combines dynamic filtering and low-level downward expansion to effectively reduce noise without affecting the audio signal. It also includes a HUSH Threshold control and a Gate Threshold control to manipulate noise reduction and provide additional downward expansion.

The Hush Pro is suitable for use in guitar rigs, preamps, stomp boxes, and effects units, leaving the tone intact while eliminating noise. The V.I.R. (Variable Integrated Release) circuitry ensures that every note played shines through naturally without typical gate "chop-off."

Overall, the Rocktron Hush Pro is a powerful and transparent stereo noise reduction system suitable for a wide range of professional audio applications.
