I'm new to this site and I don't know if this is the right forum post this in. I've recently bought a MXL 770 Microphone, and bought a Nuosiya power supply. I have an XLR cable from my microphone going into the power supply, then I have an XLR to 3.5mm going from the power supply into Audacity. It sounds terrible, do I need an audio interface, do I need a new DAW, that's what I'm trying to figure out. I'm recording an acoustic grand piano if that matters at all. Thanks to anyone who responds!
