Hey guys, question on sending 2 signals into one channel and how to do it, (if possible.) I work with a front ensemble percussion unit for a high school marching band. I have 3 marimbas and 2 vibraphones this year, and will probably have 4 marimbas and 3 vibraphones next year. In a perfect world, each marimba would have 2 mics on it, (one for the low end and one for the high end,) and the vibes would have one each. With the other instruments we mic for the band/inputs for keyboard and synth, we're running out of channels fast. I know it's not an ideal solution, but is there a way to put both mic inputs from each marimba into one channel on the mixer?
