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:

Troubleshooting  
If there is no sound from  
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.  
• 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:  
If you used the high-level  
(speaker) inputs only and  
there is no sound from any  
of the speakers, check the  
following:  
If you used the line-level  
inputs and there is no sound  
from the subwoofer, check  
the following:  
• Check the “Balance” control  
on your receiver/amplifier.  
• Check all wires and connec-  
tions between receiver/  
amplifier and speakers.  
• Make sure all wires are  
connected. Make sure none of  
the speaker wires are frayed,  
cut or punctured.  
• Receiver/amplifier is on and  
a source is playing.  
• Receiver/amplifier is on and

the following:  
• Check all wires and  
connections between receiver/  
amplifier and speakers.  
 
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.
