UPA-700

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.
