According to the owner's manual, what do the various LED colors indicate?



The thumps suggest that the output stage is receiving power. That you can't

get anything out of the woofer suggests that the signal is getting "hung up"

somewhere before the output stage.



Also make sure that all the settings are correct.



Note that the test signal has to have significant components in the range the

woofer is designed to to reproduce.

The user manual only indicates the amber and blue (normal) colors, whereas the green and red are mentioned in the service manual, which is confusing. The test signal was generated by the receiver, for the subwoofer channel. The "normal" sound, played during music reproduction cannot be heard.
