8. Troubleshooting & 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 converter.
5) If the Mini Digital Amplifier amplifier cannot be controlled by the keys on the front
panel, RS232 port or IR remote, the unit may have already been broken. Please
send it to the dealer for repairing.
