The speaker features 20 watts of output power and an internal wireless microphone receiver. The BA-55 also ships with a handheld wireless microphone for wireless operation right out of the box.

If you're speaking and need maximum power and projection, use the vertical mono mode. For wide musical spread, turn horizontal. Additional features include echo and reverb effect, anti-feedback control and 3-band built-in mixer with 2-band EQ controls.
