Question

How can I block radio interference on my USB HP Speakers

by andylopsky / November 8, 2011 12:01 AM PST

I recently moved into a location that is near a large radio tower and now my speakers are picking up a radio station and they are now unusable. Is there any way to block it? If not are there any other speakers that I can buy that will not be affected by interference?
Thanks!

Check the power . . .

Is the power supply for the speakers grounded? As in does it have the three pronged plug? Do you have a proper ground in your electrical wiring? Sometimes rerouting the speaker leads and USB cord may help.

Yeah Cory I have seen that a few times, usually a bad ground off of the input. However it CAN be that the external leads don't have sufficient shielding (rare) and the lead(s) act as an FM antenna, typically those I have seen have been grounding issues.

The power supply for the speakers is the USB port. The speakers have two cables one is the audio cable and the other is the usb where it draws power. Is there a way to ground a usb cable? Thanks.

It appears you need a better speaker setup that is in itself better shielded. If, you're that close to the radio station, you're going to have problems. Your USB setup is basic and simple and easily over comed, even if its a good one. You need to build an access for a Faraday shield or surround your cables/speakers better with protection. Google Faraday and get the idea what it does. Your PC should be using a AC 3-prong plug which should be a grounded household connection. As others stated this can help if a source of improper grounding. Even though your speaker setup uses USB, the PC needs to be grounded.
