XPA HC-1
Troubleshooting
Your XPA HC-1 was 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 HC-1, 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 your XPA HC-1 is fully inserted and is tight.
•
Verify that the Circuit Breaker hasn’t tripped.
When the circuit breaker trips, the button will pop up and extend noticeably from the rear panel.
If this happens, try resetting the Circuit Breaker by pressing the button firmly in. If the Circuit
Breaker trips a second time, please contact Emotiva, or your nearest authorized Emotiva service
representative.
Problem:
Your XPA HC-1 is operating normally, but the front panel Status LED is not lit.
Reason: The front panel status LED is turned off.
•
Set the Status LEDs 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 are lit blue.
Reason: Your XPA HC-1 is not indicating a fault condition.
•
Check your source.
•
Check your Balanced/Unbalanced Selector Switch.
•
Check your speaker and speaker connections.
Problem:
No sound is heard; the Status LED is flashing red.
Reason: Your XPA HC-1 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 your XPA HC-1
fails to come on when triggered.
Reason: Your XPA HC-1 is in Standby mode and should respond to a valid trigger signal.
•
Check your trigger cable.
•
Check the trigger settings on your source equipment.
