timmah 0 Posted December 12, 2004 I have a 100' A/V + power cable with a mic attached to it, it seems that I am getting some interference and it is causing my dvr card to make a nasty whining sound. When I connect it to just a speaker it makes a buzzing. When I connect the mic directly to the DVR or speaker it's perfect, any idea on what I can do to help with the interference? Thanks!

rory 0 Posted December 12, 2004 Could be that the wire is near some lighting fixture or high voltage? Is it run loose or is it in a counduit, can you trace the wire? If it is in the same conduit as high voltage than yes this could happen. Share this post Link to post Share on other sites
timmah 0 Posted December 12, 2004 Ah, it's next to a light switch line, I'll move it and see what happens... Thanks Share this post Link to post Share on other sites
