Q: Why does the speaker make a loud buzzing sound when I plug in the input cord
and don't play the audio source?
A: used the signal line that does not take shield empty load, can have interference signal to
enter amplifier to carry on amplification, if you hate this sound to suggest you replace the
signal line that takes shield, perhaps unplug signal line.
