[. . . ] This unit is designed to operate between 32° F and 104° F (0° C and 40° C). This unit may not function properly under extreme temperatures. 2 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. When lit, the Gate Release LED indicates that the input signal has dropped below the level set by the Gate Threshold control, thus activating the gate and providing additional downward expansion. IN/OUT switch and LED This switch allows for the Super C to be bypassed when noise reduction is not required. When lit, the LED indicates that the Super C is currently active in the signal path. When using the Super C with professional audio equipment providing a nominal output level +4dB, it is recommended that the "+4dB" setting on the unit as the Threshold adjustment will allow you to optimize noise reduction for this reference level. If the "-10" setting is used and the unit is overdriven, the "+4" setting should be used. 3 Super C Rear Panel CH. B IN jacks These ¼" mono jacks provide inputs to the left and right channels of the Super C. B OUT jacks These ¼" mono jacks provide outputs from the "CH. A" is used as a single signal source, the signal will be present in both the "CH. B" outputs. POWER jack This 2. 5mm pin jack accepts power from the 9VAC adapter supplied with the unit. 4 System Connections Mono Applications 5 Stereo Applications 6 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. [. . . ] In the absence of any input signal, the expander will reduce the gain so that the noise floor becomes inaudible. 8 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. [. . . ]
