playing.
(b) Check that the powered subwoofer is plugged in, and
it's Power switch is switched on ("•" position).
(c) Check all wires and connections between receiver/
amplifier and speakers. Make sure all wires are
connected. make sure none of the speaker wires are

are connected. Make sure none of the speaker wires
are frayed, cut or punctured, or touching each other.
(c) In Dolby Digital or DTS modes, make sure that the
receiver/processor is configured so that the speaker
in question is enabled.
(c) Turn off all electronics and switch the speaker in
question with one of the other speakers that is
working correctly. Turn everything back on, and
determine whether the problem has followed the
speaker, or has remained in the same channel. If the
problem is in the same channel, the source of the
problem is most likely with your receiver or amplifier,
and you should consult the owner's manual for that
product for further information. If the problem has
followed the speaker, consult your dealer for further
assistance or, if that is not possible, contact Da-Lite
