Just bought a UR12 and a AT2035 mic. Plugged the Ur12 into my PC via USB 2.0, it powers on no problem. Installed the Yamaha driver and such, plug in my 2035, no input. The 48v LED is off, and I can’t seem to find anything else to mess with. Mic maybe bad out of box, XLR port dead on the UR12, or am I missing something?
