RF Interference with Monitor Speakers
An ongoing issue in my area is RF getting into… pretty much everything. I’ve already written about how I dealt with it in my mic lines, but I was also hearing it through my monitor speakers. It doesn’t affect the final bounced files, but over time the high-pitched whine and random chirps started to really get on my nerves, so I decided to fix it. First step was redoing the wiring from interface to switcher to monitors with Canare 4-conductor balanced cable. That type of cable is great at rejecting interference, and while it did help, a bit of the noise was still there. Next experiment: I took some copper fabric I already had and simply draped it behind the speakers. Instant success, the noise disappeared. The copper fabric was essentially acting like a partial Faraday cage, blocking the RF before it hit the speakers. From there, the goal was to make a more permanent and controlled version of that idea. I also had to make sure I wasn’t block...
