Protection Modes and Indicators
The front LED shows the status of the amplifier. When starting up normally, the CA400 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 CA400 is equipped, except for some early production models, with four
rails 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 rail fuses are located on each device 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.
