[. . . ] DO NOT MAKE ANY INTERNAL ADJUSTMENTS OR ADDITIONS TO THIS EQUIPMENT AT ANY TIME. DO NOT TAMPER WITH INTERNAL ELECTRONIC COMPONENTS AT ANY TIME. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY VOID THE WARRANTY OF THIS EQUIPMENT, AS WELL AS CAUSING SHOCK HAZARD. POWER REQUIREMENTS This unit accepts power from the 9VAC/2A adaptor supplied with the unit. This 9 volt RMS AC voltage is internally processed by a voltage doubler which generates a bipolar ±15 volts to maintain the headroom and sound quality of professional, studio quality equipment. Using an external power source such as this minimizes excessive noise and hum problems often associated with internal transformers, providing optimal performance for the user. OPERATING TEMPERATURE Do not expose this unit to excessive heat. 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. REF switch This switch determines the sensitivity of the Super C. 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. When using only one input, the "CH. [. . . ] 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. [. . . ]
