PROTECTION CIRCUIT 

 

          The Classé 

CAV-75

 is equipped with rail fuses to protect the output drivers (see fig.1, page 7) 

and mosfet fuses to protect the mosfets, which are used as pre-drivers for the output stage of the 

amplifier. In the event that a short circuit or other problems would occur at the output of the 

amplifier, either or both of these fuses may blow in an attempt to protect the amplifier.  

 

 

 

 

To return the unit to proper operation, TURN THE UNIT OFF. Make sure that the situation 

that has triggered the protection circuit has been corrected. 

Failing to correct the situation prior to 

re-starting the unit can result in damaging vital components in the unit.

 

 

 

Replace mosfet or rail fuses (see page 4 for fuse values) that are damaged with 

exactly the 

same type and value. 

Spare fuses for the mosfet and the output section are supplied with the unit 

and included in the instruction booklet package. 

After a careful inspection of all connections and 

components in the system, re-start the unit. If unit still goes into protection mode, contact your 

local dealer or Customer Service at the Classé Audio factory---(514) 636 63 85.
