Im Using Zoom H4n as a USB interface. I plug in two SM58 Mics in the two bottom inputs, and get sound from Input 1 on the left channel and Input 2 on the right channel. I'm trying really hard to figure out how to get sound from both inputs to come out of both channels. The only solution I could think of does not seem right for some reason, maybe someone can tell me if its a good idea or not: I can construct an XLR splitter and plug in both mics into input 1 and have only input 1 turned on (which sends the same mono signal to both channels). Any thoughts?
