Send your mix to 2 connected smartphones and/or cameras, so you can record/stream for multiple platforms, or both vertical- and landscape-oriented video at the same time.
Connect speakers and up to 3 headphones (two ¼” with separate volume controls, plus one ⅛”) so everyone can easily monitor the sound.
Finally a real mixer you don’t have to plug in. Just connect a USB battery pack, stash it in the storage compartment, and you can track and stream for hours, far away from an outlet.
