The Roland BA-55, A Multi-Purpose PA with a Twist

The Roland BA-55 offers high-quality sound in just about any environment. It’s built tough yet remains lightweight, and it comes with a matching wireless microphone for singing, public speaking, etc. The BA-55 can be used as a small wireless PA system in business meetings, school classrooms, weddings, restaurants, intimate music venues and more. Something that sets the BA-55 apart from and above its competitors is the internal accelerometer that automatically switches operation mode between stereo (when horizontal) and monophonic (when vertically). Vertical mono mode is best when you’re speaking and need a lot of projection and power. Horizontal is best for music, like when using MP3/CD players at dance parties and such when the aim is a wide stereo spread. It really is that easy! The BA-55 is available in two colors: black (BA-55) or white (BA-55-WH). Select whichever of these colors that will blend in with your environment.

So Easy, a Caveman Could Use It
All things considered, the above statement is pretty accurate. There’s really nothing all that complicated about it. Simply turn on the wireless mic and/or plug in your instruments, set the volume to the desired level (in fact, it's wise to check volume levels before plugging in anything), and you're ready to go. That’s it! No need to worry about feedback, either. The Roland BA-55’s intelligent Anti-Feedback technology detects and eliminates feedback without any interruptions to your audio. The BA-55 also has a handy built-in storage compartment in which to keep your wireless microphone(s) and miscellaneous accessories. The BA-55 lets you enjoy great sound anywhere, indoors or outdoors. The BA-55 is powered through batteries (8 x AA, sold separately) or the included AC adapter.

Built-In Effects
The Roland BA-55 has Echo & Reverb effects that sound great and are easy to use. With a single twist of a knob, you can adjust both the effect type and amount. When you turn the knob from the Off position to 12 o’clock, you'll activate a plate-reverb effect that will add a natural ambience to your instruments and/or voice. When you twist from 12 o’clock to max, you'll switch to an echo effect. No need to fumble around with the knob during performances, either. If you suddenly decide to cut the effect(s), the echo & reverb can be remotely switched off from the included Roland DR-WM55 wireless microphone. How's that for convenience?!
