TROUBLESHOOTING GUIDE
If you experience a problem operating the SW10JM or SW10WM, consult this guide first. The most
common problems relate to hook up. If the problem persists, or you have additional questions,
call your local Niles dealer or Niles Technical Support at 1-800-289-4434, 305-238-4373 or
techsupport@nilesaudio.com. Be sure to call from your telephone extension nearest the system.
PROBLEM
No Sound
SOLUTIONS
Short circuit or loose wire. Check that the connections are secure and that there are no loose
strands of wire crossing from the positive to the negative terminals at the back of the amplifier
and/or the speaker.
Short circuit or a break in the speaker wire. Disconnect the speaker wire at both ends, separate the
2 conductors at both ends and test with a meter for a short circuit. If there is no short, connect the
two conductors at one end and test with a meter for continuity.
Audio cable to input is bad. Connect another cable that is known to be good.
PROBLEM
Hum or buzz sound from the speakers
SOLUTIONS
Hum or buzz may be caused by a ground loop between two of the other components in the
system. To test for another ground loop, try reversing the AC plugs of each of the components in
the system.
PROBLEM
Bass sound is weak and the stereo image is “phasey” or “blurry”
SOLUTIONS
The subwoofer is wired out of phase. Reverse the connections at the back of one speaker
