I’ve been hearing that fart for over ten years, and after hearing it today I realized I had no idea what is causing it. It’s so fartlike I’ve had boom ops joke, “Excuse me!” after plugging in.
Normal XLR from mic to a Denecke PS-1a, then via a Lectro MC41 cable into an SMQV tx. Sometimes it’s a “boat motor turning over,” sometimes a near-squeaky “petite,” sometimes a proud “floor rumbler;” it’s always a little different. It seems to only do it once per startup. Other mics only have that deep “phantom power bump” sound.
Are the electrons in the Schoeps doing some sort of happy dance when they get pushed by 48 volts?! I haven’t tested with a hardline. It seems to get worse with humidity. Heh I was just curious if anyone had any thoughts.
