3) Signal Sensing Toggle Switch
When set to "AUTO ON", the amplifier will only turn on whenever signal
(50mV minimum) is present. Once signal is no longer present, the amplifier
will shut off automatically after about 20 minutes. Note that the power switch
must be in the ON position at all times for the AUTO sensing to work.
Set to "+12V TRIG" if the amplifier is being powered by an external source.
The power switch can either be in the ON or OFF position. However, we
suggest keeping the power switch in the OFF position so the amplifier shuts
off once the external source is turned off.
4) Bypass/Lowpass Toggle Switch
Setting the switch to "BYPASS" will turn the crossover control OFF. This
setting is best when using the XJ-300ST in the 2-channel or 2.1
configuration.
Setting it to "LOWPASS" turns the crossover control ON. This setting is best
when using the XJ-300ST as a mono block or subwoofer amplifier.
