ROLAND BA-55 WH Battery Powered Portable Wireless PA Amplifier w/ Mic White BA55

The Roland BA-55 battery-powered portable amplifier offers self-contained, high-quality, sound reinforcement for any environment. Rugged yet lightweight, it comes bundled with a matching wireless microphone so you can use it as a small wireless PA system in school classrooms, business meetings, restaurants, weddings, intimate music venues, and more.

The BA-55 boasts 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.
