QuestionHi! Hoping you have an idea of what's going on here. I am getting
background white noise along with a very low volume radio sound through
my stereo speakers. This happens regardless of what component is selected,
e.g. AUX, CD, Phono.
The equipment is a Harman Kardon 2 channel receiver. The problem seems
to be with the used Bose Acoustimass 5 speaker system. If I hook up my
regular JVC speakers, I have no issues. Any ideas as to why the Bose system,
with the powered subwoofer and smaller speakers would generate white
noise and also speak up a little radio signal (the one that the receiver is tuned
to).
Thanks for your help!
AnswerHi Galen,
The only idea as to why the Bose system is picking up radio signals as well as white noise, likely from the wiring or radio signal interference, or perhaps internally generated, is the design of the Bose system. It could be that the Bose speakers aren't properly designed or shielded and are picking this stuff up. The other possibility is that the cables you're using are sensitive enough to pick up such signals and aren't shielded.
You don't mention the resistance of the JVCs vs. the Bose (8 ohms?) but my guess, without having that info, is that the Bose run at a lower resistance (4 or even 2 ohms instead of 8 ohms) which makes them more suseptible to picking up radio interfere, and a good set of shielded cables from your receiver to the speakers would help. To save yourself $$$, find the Bose unit that is the "noisiest" and try buying enough shielded speaker cable to plug that one in, and see if it goes away. If it does, and you want to keep the Bose system, then you can then go buy enough shielded cable for all of them.
That's about the best I can do with limited information. Do remember that it could be a problem with the Bose system itself, so if it's new you might want to return them and try another, as it might be a manufacturing defect, so get them back while they're still under warranty if you can. Good luck! Cheers, Wink
