Static From Tweeter
alias -- Tue, 05/30/2006 - 13:07
I was hoping that someone could help me with a problem.
I have a pair of Totem Mite speakers that I'm using with a Denon receiver. Ever since I've had them I've noticed a distinct static emanating from the tweeters of both speakers. The static occurs if the receiver is on and there is no music playing. I'm using a power with the receiver and all the outlets are grounded. I've checked the speakers with a different AMP with and without the power bar and the static still persists.
What could be causing this static and how can I fix it?
Any advice would be much appreciated.
Is the static constant or intermittent?
It is constant.
Have you tried disconnecting the source (DVD player, etc) that is on when you hear the static? Is the static different with different sources?
I've tried it with 2 different receivers with the DVD player on and off. The static remains the same with all of the combinations. It appears as if just having the receiver on causes a static to emit from the speakers. Is this a normal phenomenon?
Thanks for taking an interest
Are you running long speaker cables? The problem might be RFI.
Yes, the runs are fairly long, but I could shorten them. What is RFI?
Radio Frequency Interference. Our homes are full of RFI from digital sources such as satellite TV receivers and computers to stuff that comes in over our power lines. Make sure that you are using good quality, shielded cables. Long runs can pick up RFI.
It sounds like a defective component in the receiver is creating the static. I would take it to a shop for troubleshooting and repair.

If the static is constant, and you hear it even when the volume is turned all the way down, your amplifier (or amp section of the receiver) is at fault. It could be a grounding problem, or simply poor signal:noise ratio in that component. These are the only two likely causes, since you hear the noise in both channels.

I'm certainly not the world's foremost expert, but if you experienced the same problem with two different receivers or amplifiers, the problem can only be in your speaker cables. Either long runs are inviting RF/EMI issues as was previously noted, or you have breaks in your cable runs. Just my two cents.
