When set to "AUTO ON", the amplifier will only turn on whenever
signal (50mV minimum) is present. Once signal is no longer present for
about 8 minutes, the amplifier will shut off automatically.
If set to "AUTO OFF", the amplifier will stay on whether or not there
is signal present.
Note that the amplifier needs to be powered ON in either case.
4) Bypass/Lowpass Toggle Switch:
When set to "BYPASS", the amplifier crossover control is OFF.
This setting is best when using the XJ-300FR in the 2-channel or 2.1
configuration.
When set to "LOWPASS", the crossover control is ON. This setting
is best when using the XJ-300FR as a mono block or subwoofer amplifier.
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 speakers.
To do this with the highest accuracy, you will need an SPL meter supplied
at most electronics stores.
