Battery Powered Portable Amplifier/PA System in White

Roland BA-55 White is a battery powered portable amplifier. The unique Roland BA55 portable PA provides self-contained, high-quality, and battery-powered sound reinforcement for any environment. It’s solidly built yet lightweight, and comes bundled with a matching wireless microphone for public speaking, singing, and many other events. Use the BA 55 portable PA as a small wireless PA system in school classrooms, business meetings, intimate music venues, and more. In a cool and convenient twist, the BA-55 portable PA contains an internal accelerometer sensor that automatically switches operation between stereo output (when positioned horizontally) and mono output (when positioned vertically). If you’re speaking and need maximum power and projection, use the vertical mono mode. For wide musical spread, turn horizontal. It’s that easy.
