Couple interesting videos about the noise:What's up with this video? They claim that a "sescom cable" is the only way to eliminate the noise... I gather that any attenuator would work to keep the camera's mic level from overloading, but they just keep calling it THE AMAZING MAGICAL MIRACULOUS WONDERFUL SESCOM CABLE or some crap... WTH?
yeah, audio snake oil cable! Too bad he didn't explain what it does.
Advice is a form of nostalgia, dispensing it is a way of fishing the past from the disposal, wiping it off, painting over the ugly parts and recycling it for more than it’s worth.
