LUR652E-LUR65EW TROUBLE SHOOTING
If you hear obvious distortion from the speakers,
immediately lower the volume level of your receiver. Those
sounds often indicate that either the receiver or the speaker
is being over driven, and damage can result in playing your
source material (music-CDs-DVD-MP3) at high volume
levels for prolonged periods of time. You should also avoid
turning the bass or treble controls fully up and using your
"Loudness button" when the volume level is at or above
normal listening levels.
The Loudness button on most receivers is designed to add
depth when your system is being used for background
music or at very low volume.
Distorted or unnatural sound can indicate poor connections,
defective electronics, damaged source material or speaker
failure. If only one of your speakers has poor sound quality,
check the speaker wire and audio connections.
That doesn’t fix the problem? Try putting each speaker in
place of one another (swapping). If the sound remains poor
on the suspect speaker after swapping location and the
distortion moves with the speaker to the new location, the
speaker may be the problem. If the distortion remains in
the original location then the problem is elsewhere in your
audio system or speaker wiring. You must have proof of
purchase to receive warranty service.
Please keep your original sales receipt and be prepared to
provide this receipt in the event you require service, as your
original receipt is considered the best proof of purchase and
indicates the date you purchased your Dual product.
