No audio from second monitor
So I ordered two yamaha HS80m's off ebay refurbished. They have no scratches or anything and look brand new.
I plugged them into my profire 610 (Line 1 & 2) and played something but I only get audio in my left speaker. I tried switching the cables but I still only get audio in my left speaker. As far as I can tell there is activity in both outputs though.
Is the speaker broken? What should I do?
