Re: Rode NT1-A requires 3 minutes warm-up time

I will clean the flux and debris off tomorrow.

Many thanks for pointing me to the area and the detailed instructions to clean it up!
I will give it a try to remove the discolored coating and flux. It will take some time because I have to order

Re: Rode NT1-A requires 3 minutes warm-up time
I tried your suggestion. But as soon as I remove the cover, connect the XLR cable and switch on the phantom power, the mic is caught in a ground loop. Or is it because the EMI/RFI shield is missing? I

Re: Rode NT1-A requires 3 minutes warm-up time
From the images posted the capsule doesn't look too bad, honestly, i.e. pretty normal for an older/used mic I'd say, but I'm not an expert. (Of course you can't tell for sure from a visual inspection

Re: Rode NT1-A requires 3 minutes warm-up time
High humidity is a real problem here. I usually store microphones in dry boxes. Especially during the hot and humid summer season. The NT1-a seems to be particularly susceptible to moisture.

A short update.
I tried a continuous test recording near the house for several hours today.
