processor, use care with this setting as the LFE channel may
contain powerful low frequencies which, although normal in a
cinema, may overload a domestic subwoofer.
If, during a programme, you hear popping or thumping noises
coming from the subwoofer, immediately turn the AV Processor's
volume level down and then back off the LFE level. If this does not
cure the problem, back off the volume level at the subwoofer.

Setting the AUTO switch to ON automatically turns the
subwoofer on when a signal is detected at any of the inputs and
turns it off (Standby Mode) after a period of inactivity. We
recommend the AUTO switch be set to ON for normal operation.
In AUTO mode the indicator on the front of the subwoofer will
glow RED when the unit is in Standby and GREEN when
operational. If your subwoofer is disconnected from the mains
or the Power switch is “Off”, the indicator will be extinguished.
