Common problem:

Q: All my lines are connected, but there is no sound output?

Answer:

1. Check if the gear switch is in the OFF state. Check whether the tube light is on after the switch is turned on. If the fault still exists, replace the power supply with the same voltage output (must be 12V) and test again.

2. If the indicator light is on and the gear position switch is also on, unplug the power supply and re-insert the tube.

3. If both of the above are normal, check if the playback device of the input source is paused, muted, or the volume is at its minimum.
