Introduction Congratulations on your purchase of Rocktron's HUSH® The Pedal - guitar noise reduction footswitch!HUSH The Pedal is designed to eliminate the background noise or "hiss" produced by high gain amplifiers when a signal is present without descimating your tone. A 30dB drop below the threshold would result in a drop of 60dB of the output signal (30dB of gain reduction). The absence of any input signal will result in the expander reducing the gain so that the noise floor is inaudible. The Variable Integrated Release (V. I. R. ) technology contained in each HUSH circuit automatically adjusts the release rate of the expander based on the dynamic decay rate of the incoming signal. If the input signal stops suddenly, downward expansion will occur rapidly (similar to a gate). If the input signal decays slowly, expansion will occur slowly without disrupting the dynamic decay of the input signal. The THRESHOLD control should be adjusted by listening to the noise floor while not playing. Turn the THRESHOLD control clockwise to the point where the noise floor becomes inaudible. Turning too far past this point will cause the downward expander to attenuate the output level too quickly and not allow the signal to decay as long as it should. Functions Right Side 1 2 3 4 Left Side 5 6 7 8 1= This switch activates the HUSH circuitry. 2= Threshold Control - Turn Clockwise to increase the amount of HUSH added to the signal. In high gain situations turn the Threshold more towards "Max". [. . . ] 2= Threshold Control - Turn Clockwise to increase the amount of HUSH added to the signal. In high gain situations turn the Threshold more towards "Max". 3= "ACTIVE" LED - When lit the HUSH is "active" or "on" 4= 9 Volt DC Adapter Input 5= Input Jack 6= Output Jack 7= Battery Compartment - To access, remove two screws, pull cloth tab to remove the battery.
