Protection Modes and Indicators

The front LED shows the status of the amplifier. When starting up normally, the CAV500 will show a FLASHING

RED LED for about 15 seconds and if all is normal, the LED will go SOLID RED. If there is a fault, the LED will

go to a FLASHING GREEN LED. The CAV500 is equipped, except for some early production models, with ten

Mosfet protection fuses. In the event that one or more of these fuses would blow, the technician will first need

to identify and cure the cause of failure (please report to troubleshooting guide). When the cause has been

identified, disconnect the unit from the system including the AC power. Remove the top cover and look for

damaged or burned components. If no other components than the fuses appear to be damaged, the

technician can then replace the broken fuses with the same value and rating (please report to fuses section).

The Mosfet fuses are located on the control board. When replacing fuses, please make sure that the fuse

holder are holding the fuses very tightly. A loose fuse holder can translate into distortion on top of the signal.
