Review on 🎤 Moukey MWm-5 Karaoke Microphone: Dynamic Cardioid Wired Mic for Singing, Speech, & Events - Grey by Sara Houck

I just bought this mic to make announcements through our amp using the red and white RCA connectors. Microphone not working. It doesn't seem to have room for batteries, so I'm assuming it's getting power from the RCA cables somehow. In any case, it's probably user error. Update: It works fine on one of my bluetooth speakers with an aux input. My amplifier must not be designed to power a microphone.
