u/Hatter-83

Picked up this mixer/amp. I’m using it for Karaoke and running laptop signal and mics through it. On my old one I was plugging laptop audio into the 2 rca jacks labeled tape in. I believe that was giving me sterio sound, right and left. On this new one, I want to plug it into media in, but the one rca is damaged, so I’ve been using the 1/4 jacks next to it labeled inputs summed. Would it be worth getting those rca jacks replaced, or just keep using the 1/4 jacks?
