Rack-mountable stereo noise reduction effect from HUSH series that is the ultimate noise exterminator for guitar players, providing the maximum in performance, eliminating hiss, hum, crackle, and other annoying noise problems from user’s setup. With a single set of HUSH Threshold and Gate Threshold controls it allows for easy manipulation of both channels simultaneously. It provides an effect IN/OUT (or bypass), and an input sensitivity switch conveniently located on the unit’s front panel. With a dynamic range of 105dB and 72dB of effective noise reduction, the effect becomes a valuable tool in every guitar player’s rack, leaving the guitar’s tone intact. Unlike those tone-squashing noise gates, Rocktron’s V.I.R. (Variable Integrated Release) circuitry allows every played note shine through and sustain naturally. Maximum input level: +15dB (+4 Ref.)/+5dB (-10dB Ref.). Input impedance: 470 ohms. Output impedance: less than 100 ohms. Effective noise reduction: 72 dB. Frequency response: ±.5dB, 10 Hz – 27 kHz. Dynamic range: 105 dB. Noise floor: -100 dBu. THD + Noise: .041% @ 0dBu, 1kHz (typ). Dimensions: 483 x 152 x 44.45 mm.
