Troubleshooting
The UPA-700 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 UPA-700 but, if you do, here are a few things you could try:
Problem: No sound is heard from any channel (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 UPA-700 is fully inserted and is tight.
Problem: The UPA-700 is operating normally, but the front panel Channel
Status LEDs aren't lit.
Reason: The front panel Channel Status LEDs are turned off.
•
Set the Status LEDs switch on the rear panel to On.
Problem: No sound or distorted sound is heard from one or more
channel(s); the Standby button is lit blue; the Channel Status LEDs are all lit
blue.
Reason: The UPA-700 is not indicating a Fault condition.
•
Check your source.
•
Check your speakers and speaker connections.
Problem: No sound is heard from one or more channels; the Standby button
is flashing amber; and one or more Channel Status LEDs are flashing red.
Reason: The UPA-700 is in Protect mode, which indicates a Fault condition.
•
Switch the 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 Standby button is amber and the UPA-700 fails to come on
when triggered.
Reason: The UPA-700 is in Standby mode and should respond to a valid trigger signal.
•
Check your trigger cable.
•
Check the trigger settings on your source equipment.
