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

Troubleshooting
If there is no sound from
any of the speakers, check
the following:
• Receiver/amplifier is on and
a source is playing.
• Review proper operation of
your receiver/amplifier.
If there is no sound coming
from one speaker, check the
following:
• Check the “Balance” control
on your receiver/amplifier.
• Check all wires and connections between receiver/
amplifier and speakers.
• Make sure all wires are
connected. Make sure none of
the speaker wires are frayed,
cut or punctured.
If the system plays at low
volumes but shuts off as
volume is increased, check
the following:
• Check all wires and
connections between receiver/
amplifier and speakers.
turn off after approximately five minutes. The speaker
will turn on when your receiver/amplifier begins playing again.
• Make sure all wires are connected. 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 impedance requirements of your
receiver/amplifier.
If you used the high-level
(speaker) inputs only and
there is no sound from any
of the speakers, check the
following:
• Receiver/amplifier is on and
a source is playing.
• TLX271P is plugged in.
• Check all wires and connections between receiver/
amplifier and speakers. Make
sure all wires are connected.
Make sure none of the
speaker wires are frayed,
cut or punctured.
• Review proper operation
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 you used the line-level
inputs and there is no sound
from the subwoofer, check
the following:
• Receiver/amplifier is on and
a source is playing.
• TLX271P is plugged in.
• Check all wires and connections between receiver/
amplifier and speakers. Make
sure all wires are connected.

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,
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/
processor owner’s manual or
contact the manufacturer.
Do not hook up both inputs.
Doing so will adversely affect
the performance of the system.
Set Input Select switch to
“Line.”
Note: Some receivers/amplifiers have a single (mono)
subwoofer output. In this
case, it is necessary to use a
“Y”-connector (not included)
to properly hook up the
speakers using this method.
