To connect the subwoofer to line output (pin jack) terminals of the amplifier
• Connect the main speakers to the speaker output terminals
of the amplifier.
• Amplifier line output terminals are generally labeled PRE
OUT or SUBWOOFER OUT.
* For PRE OUT terminal connection, the amplifier must
possess at least two sets of PRE OUT terminals. With
some amplifiers with only one set of PRE OUT terminals,
connection can result in no sound from the main left and
right speakers. In this case, select the method of
connecting to the speaker output terminals.

Notes
• When connected to line output terminals of the amplifier,
other speakers should not be connected to the OUTPUT
terminals on the rear panel of the subwoofer. If connected,
they will not produce sound.
