8.0 E4 System Troubleshooting A number of fault conditions can be displayed in the Input Status section: DC Sense Fault: A power supply fuse, output FET, amplifier module, or some combination of the above has blown. The unit should be replaced. Amplifier Module Fault: When the Amplifier Module fault occurs by itself it can be caused by any of the following: • Shorted speaker line – Check the loudspeaker line for shorts. • System power exceeds 400W – Check that system power does not exceed 400W.
