• A Power-On Self-Test failure
•A DSP error
•The DSP is offline

To determine the severity of the error, cycle the E4 unit power off
and back on again. If the SYSTEM STATUS indicator is now off,
the E4 system has logged an error, but is still operational.

software you can identify the cause of the error, and determine an
appropriate solution.

Check for
• Shorted wiring
• Overdriven amplifier
(reduce output gain)
• Transformer saturation
• Entry in Installer™ software error log
When an amplifier fault occurs, the amplifier mutes its outputs
and indicates an error. After a short period of time the amplifier
will try to operate again. If the fault condition persists, the amplifier will attempt to restart six times, after which it will remain
muted.
Amplifier faults are typically caused by a shorted speaker line, an
overdriven amplifier, or a saturated output transformer.
• To check for a shorted speaker line, remove the speaker connection from the amplifier channel. If this resolves the problem,
locate and correct the shorted loudspeaker line.
• To make sure that you are not overdriving the E4 output,
change to a different source. If the problem no longer exists,
use the Installer™ software to reduce the input level of the original source that was overdriving the output.
• To make sure an output transformer is not being saturated,
check to see if the correct speaker EQ setting is selected.
If none of these actions solve the problem, read the instructions
in the following flow chart or check the error log using the
Installer™ software.

shut down during
operation?
No
Is SYSTEM

Does the Installer™

• Check the number of loudspeakers connected to the E4 unit.
Verify that the total sum of loudspeaker taps connected to the
E4 unit does not exceed 400W.
• Verify that there are no shorts on
the speaker output lines.
• Switch POWER to OFF.
• Disconnect the load and switch
POWER to ON.
• Verify that there are no shorts on
the speaker output lines.
See amplifier fault troubleshooting
section for course of action.
