In fact, the MOBILEMAN is the world?s first battery-powered, portable P.A. system with a subwoofer. Because it is a VocoPro, singers will appreciate the on-board DSP effects that are designed especially for singing. Whether your next event is a school auditorium, coffee shop, or hotel ball room, take along a MOBILEMAN and get the job done right!
