7. Troubleshooting and Maintenance
1) When there is no output audio:

Check if there is any signal at the input.

Check if there is any signal at the output.
We can check these by using an oscilloscope or a multimeter. If there is no signal
input/output, maybe the input/output cables broken or the connectors loosen, please
change for another cable.

Check if the output port number is the same with the controlled one.

If not the problem mentioned above, probably there is something broken inside the
unit, please send it to the dealer for repairing.
2) If the POWER
indicator doesn’t work or no respond to any operation, please make
sure the power cord connection is good.
3) If the output sound is interfered, please make sure the system is grounded well.
4) If the static becomes stronger when connecting the audio connectors, it probably
due to bad grounding, please check the grounding and make sure it connected well,
otherwise it would damage the amplifier.
5) If the PA3V amplifier cannot be controlled by the keys on the front panel, RS232 port
or the IR remote, the unit may has already been broken. Please send it to the dealer
for repairing.
