I've been experiencing a strange problem when I try to wire extension cables into my Rode Videomic. There is a high pitched pulsing sound that I've noticed with 3 of my 4 extension cables. There is no pulsing sound when I attach the mic directly to my recorder. This sound persists even away from electronic sources which could cause interference. And, again, with one of my cables, there is no extraneous sound.
The Videomic uses a 3.5mm jack, so I've been using headphone extension cables. For all my research, I can't figure out if there is a difference between headphone extension cables and microphone extension cables. Maybe this is the problem?
Although one of my cables works, it is not long enough. I bought a new cable, and that one buzzes too.
Any ideas what's going on?
