First of all my setup:
I bought this AT2035 second hand. When I turn on phantom power I get A LOT of hiss (or hum, idk the difference) it gets to the point that if I turn the mic gain all the way up the noise clips… I haven’t returned it because it doesn’t always happen. Sometimes I turn it on and everything is just fine. I have been trying restarting my computer several times until the noise is gone, but this is annoying! With my AT2020 I never get this problem.
I was wondering if there is any solution to this
