Troubleshooting

The SA-250 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 

SA-250, 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 SA-250 is fully inserted and is tight.

Problem: The SA-250 is operating normally, but none of the front panel  

status LEDs are lit.

Reason: The front panel status LEDs are turned off.

•  Set the Status LEDs switch on the rear panel to On.

Problem: No sound or distorted sound is heard; the LEDs are lit blue.

Reason: The SA-250 is not indicating a fault condition.

•  Check your source.

•  Check your Balanced/Unbalanced Selector Switches.

•  Check your speakers and speaker connections.

Problem: One channel is louder than the other; I’m sure my source is balanced.

Reason: You have the gain set differently on the two channels of the SA-250.

•  Check your Gain Switch settings.

Problem: No sound is heard; one or more Status LEDs is flashing red.

Reason: The SA-250 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 Standby LED is lit red and the SA-250 fails to come on when triggered.

Reason: The SA-250 is in Standby mode and should respond to a valid trigger signal.

•  Check your trigger cable.

•  Check the trigger settings on your source equipment.
