Speaker Connections
Connection Tips
Speakers and electronics ter-
minals have corresponding (+)
and (–) terminals. It is impor-
tant to connect both speakers
identically: (+) on the speaker
to (+) on the amplifier and
(–) on the speaker to (–)
on the amplifier. Wiring “out
of phase” results in thin
sound, weak bass and a poor
stereo image.
If your receiver does not have a subwoofer output:

any of the speakers, check
the following:
• Make sure all wires are con-
nected. Make sure none of the
speaker wires are frayed, cut
or punctured.
• If more than one pair of
main speakers is being used,
check the minimum imped-
ance requirements of your
receiver/amplifier.
If there is low bass output,
check the following:
• Make sure the connections
to the left and right “Speaker
Inputs” have the correct
polarity (+ and –).
• Make sure that the TLX271P
is plugged into an active
electrical outlet.

If your receiver has a subwoofer output:
The TLX271P incorporates two
different types of line-level
inputs that allow you to
optimize the loudspeaker’s
performance in your system.
If your receiver/processor’s
subwoofer output is already
low-pass filtered, meaning the
high frequencies have been
removed by the receiver, use
the subwoofer input labeled
Direct.
If your receiver/processor’s
subwoofer output is full range, processor owner’s manual or
meaning the high frequencies
have not been removed by the
receiver, use the subwoofer
input labeled Normal.
If you are unsure as to which
type of subwoofer output your
receiver/processor contains,
please consult your receiver/
contact the manufacturer.
Do not hook up both inputs.
Doing so will adversely affect
the performance of the system.
