FRONT PANEL
DDT™ ACTIVE LED (1)
Illuminates when DDT™ Compression is taking place. With the ENABLE/DEFEAT switch in the DEFEAT position, the LED indicates when clipping distortion is occurring.
POWER LED (2)
Illuminates when AC power is being supplied to the amp and the associated channel is operational. Illumination is delayed slightly during the
INPUT SENSITIVITY (3)
Maximum power amplifier input gain (minimum sensitivity) is achieved at the full clockwise setting. This setting yields maximum mixer/system headroom. A setting of less than full clockwise will yield lower system noise at the expense of headroom. Calibration indicates sensitivity in dBV necessary to attain the full output power rating.
POWER SWITCH (4)
Depress to “on” position to power up unit.
AIR EXHAUST PORT (5)
This is where the hot air from the heat sinks exhaust from the amplifier. Any restriction or blockage could cause excessive oper- ation temperatures, and the unit could shut down!

CIRCUIT BREAKER (6)
The CS® 500A uses a circuit breaker in place of the main fuse. This breaker is provided to limit the current to the analog power supply and thereby protect it from overheating and possible destruction due to fault conditions in the amplifier. The trip current value has been carefully chosen to allow continuous power output performance while still providing adequate protection for the power
supply. Normally, this breaker should not trip unless there is a fault in the amplifier circuitry that draws excessive mains current. However, abnormal conditions such as a short circuit on either or both channels or continuous operation at overload or clipping,
