Introduction Congratulations on your purchase of the Rocktron HUSH® Super C ™! Designed for guitar applications, the Super C utilizes the latest in HUSH noise reduction technology (including the SSM2000 HUSH IC, available from Analog Devices) combined with the latest V.I.R. (Variable Integrated Release) circuitry configured as a noise gate. This combination provides extremely effective noise reduction while playing and complete silence when not.
OPERATING PRECAUTIONS NOTE: IT IS VERY IMPORTANT THAT YOU READ THIS SECTION TO PROVIDE YEARS OF TROUBLE FREE USE. THIS UNIT REQUIRES CAREFUL HANDLING. All warnings on this equipment and in the operating instructions should be adhered to and all operating instructions should be followed. Do not use this equipment near water. Care should be taken so that objects do not fall and liquids are not spilled into the unit through any openings.
Super C Front Panel POWER LED When lit, this LED indicates that the Super C is powered and ready for operation. HUSH THRESHOLD control This control sets the point at which the downward expander and dynamic filter begin to operate. GATE THRESHOLD control and GATE RELEASE LED This control is used to determine the level at which the gate will begin to operate. As the input signal drops below this level, the gate will activate and downward expansion will begin.
Super C Rear Panel CH. A (MONO) / CH. B IN jacks These ¼" mono jacks provide inputs to the left and right channels of the Super C. When using only one input, the "CH. A (MONO)" jack must be used. CH. A / CH. B OUT jacks These ¼" mono jacks provide outputs from the "CH. A" and "CH. B" channels of the Super C. Note: 4 When "CH. A" is used as a single signal source, the signal will be present in both the "CH. A" and "CH. B" outputs. POWER jack This 2.

Operation When used properly, the HUSH® Super C should be completely transparent (i.e., it should not effect the guitar signal—only the noise). To maximize the performance of the Super C, it is necessary to understand its front panel controls and how they work together. By understanding how these controls work, it will be easier to correctly set up the Super C to suit any application. The Super C front panel provides two controls which each manipulate both channels simultaneously.
This means that if a signal is present at the input which consists of primarily bass components, the dynamic filter will reduce mid or high band noise. If no mid or high band information is present, the filter will close down to a pre-set cut-off point of 1kHz (allowing only frequencies of 1kHz and below to pass). However, if the input signal has high frequency components present, the dynamic filter will open fully to pass the signal and eliminate the possibility of a loss of high end frequency response.
The front panel HUSH Threshold control determines the minimum input level at which the HUSH filter and downward expander will begin to operate. Setting this control too high will result in a loss of sustain, as notes will tend to die out much faster than they should. Conversely, when set too low, the expander will close too late (if at all) and the noise floor will remain audible. Gate Section The other half of the Super C consists of a noise gate.
