XPA-100
Troubleshooting
The XPA-100 is carefully designed and manufactured from high-quality precision
components to ensure years of trouble free operation. We really doubt you’ll ever have any
problems with your XPA-100 but, if you do, here are a few things you could try:
Problem: No output (nothing is lit).
Reason: You have no AC power.
• Verify that the rear panel AC Power switch is On.
• Verify that your circuit is live.
• Verify that the line cord on the XPA-100 is fully inserted and is tight.
Problem: The XPA-100 is operating normally, but neither of the front panel
status LEDs are lit.
Reason: The front panel status LEDs are turned off.
• Set the Status LED switch on the rear panel to On.
Problem: No sound or distorted sound is heard; the Standby button halo is
lit blue; the status LED is lit blue.
Reason: The XPA-100 is not indicating a Fault condition.
• Check your source.
• Check your speakers and speaker connections.
Problem: No sound is heard; the status LED is flashing red.
Reason: The XPA-100 is in Protect mode, which indicates a Fault condition.
• Switch the rear panel AC Power switch Off and On to clear the Fault condition.
• If the fault remains, look for a shorted speaker cable or damaged speaker.
• Check your sources and source connections (a bad interconnect, DC on the input,
or an otherwise bad source component can cause a fault).
Problem: The halo around the Standby button is lit amber and the XPA-100
fails to come on when triggered.
Reason: The XPA-100 is in Standby mode and should respond to a valid trigger signal.
• Check your trigger cable.
• Check the trigger settings on your source equipment.
