5) Phase Setting:
If you are using the XJ-300FR to power a subwoofer, you will
need to set the arrival time of the subwoofer's frequencies to that of your

supplied at most electronics stores.
To set the phase:
A) Send a 50Hz continuous tone signal through the speakers and
the subwoofer at the same time.
