Troubleshooting
If problems occur, the first step should be to verify that the PA 2-250 is set to the proper line voltage
for your AC power source and that your power source is operating correctly.
Problem: No sound is heard from any channel (the On/Off LED is not lit)
You have no AC power
• Verify that the circuit is live and the rear panel Power switch is On
• Verify that the line cord on the PA 2-250 is fully inserted and is tight
Problem: No sound is heard from any channel (the On/Off LED is lit red)
The PA 2-250 is in Standby mode
• Press the On/Off button
• Assert a trigger signal or verify that a trigger signal is present
Problem: No sound or distorted sound is heard from one or both channels
(the Power LED and both Channel Status LEDs are lit blue)
The PA 2-250 is On and is not indicating a fault
• Verify that the input configuration for that channel is correct
• Check your source and your input cabling
• Check your speakers and speaker connections
Problem: No sound is heard from one or both channels
(the On / Off LED and one or both Channel Status LEDs are flashing red)
The PA 2-250 is indicating a fault on one or both channels (the flashing Channel Status LEDs
correspond to the channels where a fault has been detected).
• Verify that the speaker cable(s) and speaker terminals are not shorted
• Verify that the speaker itself is not shorted or damaged
(try the speaker on the other channel and see if the fault “moves”)
• Verify that the source is not faulty
(try that input cable on the other input and see if the fault “moves”)
• Disconnect all inputs and outputs and reset the PA 2-250
If the fault condition persists after all inputs and outputs have been disconnected and the
fault has been reset, and the Voltage Select switch is in the proper position, please contact
Sherbourn Technical Support.
