Paired with its included wireless microphone, the BA-55 is perfect not only for musical performances, but also for school presentations, meetings, special events, houses of worship, and other events.

The BA-55 has a three-channel configuration, with one channel featuring an integrated 2.4 GHz wireless receiver for use with the included wireless microphone. The second channel can accept a second Roland wireless microphone or a standard wired microphone, while the third channel has RCA, 1/4-inch, and 1/8-inch stereo inputs for audio, instrument or other line input use.
