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 power-up cycle due to the transient suppression/thermal fault circuitry. If either channel experiences fault conditions or
exceeds the safe operating temperature limits, then that channel will shut down and the associated power LED will go out indicating
such conditions exist. Also, whenever the BRIDGE mode is selected, the power LED on channel B is defeated (OFF), just as if there
were a fault condition on channel B. This provides a positive indication that the CS 800S is in bridge mode.
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 operation
temperatures and the unit could shut down!
REAR PANEL
CIRCUIT BREAKER (6)
The CS
®
800S uses a circuit breaker in place of the main fuse. This breaker is provided to limit the current to the digital 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, especially into
2 ohm load, will cause the breaker to trip. If this occurs, simply reset the breaker and correct the cause of the overload. When tripped,
the button on the breaker will be outward nearly 1/2", and can be reset by pushing inward. A normal reset button length is about 1/4".
If this “thermal” type breaker does trip, then simply pushing the button back in will reset it after waiting a brief period of time to allow it
to cool. If the breaker trips instantly when you attempt to reset it, the unit should be taken to a qualified service center for repair.
