PROTECTION CIRCUIT
The Classé
CAM200
equipped with a rail currents sensors to protect the output drivers under
extreme condition such as short output, and Mosfet fuses (2AG 1/2 PT, 1/2 amp fast blow) to protect
the Mosfets, which are used as pre-drivers for the output stage of the amplifier.
Also the CAM200 has an output DC sensor; this will put the CAM200 on protection mode in the
event DC occurs at the output of the amplifier or heavy clipping of output signals. There is also an
AC line fuse protecting the unit. It is located at the back of the unit immediately above the AC
receptacle (see fig.1, page 10).
If the protection circuit of the unit is triggered or any of the fuses has blown, the FRONT
PANEL POWER LED will go to BLINKING GREEN, indicating a “fault” condition.
WHEN THE PROTECTION CIRCUIT HAS BEEN TRIGGERED, UNPLUG THE AMP
FROM THE OUTLET. Check for any possible event that might trigger the protection circuitry such
as short output, blown Mosfet fuses, etc. After the situation which has triggered the protection
circuit has been clearly identified and corrected, attempt to re-start the unit. IF THE UNIT STILL
GOES INTO PROTECTION MODE, OR IF IT APPEARS THAT PROTECTION FUSES DID
BLOW, CONTACT YOUR LOCAL DEALER. DO NOT TRY TO CHANGE A BLOWN FUSE.
REPLACING A FUSE WITHOUT CHECKING FOR COMPONENT FAILURE COULD
RESULT IN FURTHER, SERIOUS
DAMAGE TO VITAL COMPONENTS IN YOUR
AMPLIFIER.
