Okay good thanks for letting me know I’m not crazy.

Btw have you tried using an XLR cable with grounded shells? If not, Read on below…

I mind had a really bad ground hum that would appear anytime I touched the mesh grill.

I was almost going to send it in to Sony immediately for repair. Even filled out a repair ticket.

I had been using mogami gold xlr cables and also pro co cables from sweetwater and LiveWire elite cables from guitar center. Had ground hum on all of them.

I made a post in the high end forum prior to my comment here and someone gave me the advice to ground an XLR cable to the shell. I assumed they meant only at the microphone end but they meant both ends.

I do have a soldering iron so I opened up the connectors on my cables and saw that none of my cables have pin 4 (the connector shell) connected to the ground wire.

Seems like there’s no industry standard on using pin4 for ground or not. I double checked the C100 manual and sure enough it said to use a cable that has grounded shells.

So… that makes me wonder if this is actually just a symptom of using cables without grounded shells, or cables that aren’t up to Sony’s specs for the mic!

Unfortunately I don’t have any copper wire to solder them up myself and check but I did call redco and special order a cable with grounded shells. I asked them to ground both end shells.

I am going to try and get some copper wire in the meantime and experiment with grounding just the female shell that goes to the mic as well
