A professional and economical mixing station for up to three microphones, the Rolls MX310 is the dedicated mix box Sweetwater audio pros recommend having on hand for low-mic count applications. A trio of balanced XLR inputs with phantom power capabilities allows you to balance three microphone sources with a single XLR mic/line-level output send. Three per-channel levelers on the front plate give you total volume command. At the same time, just beside them sit a pair of 3.5mm stereo inputs/outputs for stereo line-level connections to your phone, radio, or CD player, with output monitoring for your camera, computer, earbuds, and more. Weighing in at just one pound, this compact mixer will work hard anywhere and everywhere you need it to and for a variety of small-footprint applications — from coffeehouse stage mic mixing to department store paging and beyond.
