April 6, 2011 - Roland have introduced the BA-55 Portable PA System, a compact, lightweight, and efficient battery-powered amp that's designed for any small event requiring sound amplification. Paired with the wireless microphone included, the BA-55 is perfect for musical performances, and 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 its 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.
The BA-55 offers global tone controls for quick sound adjustments and an echo effect that can be switched on from the wireless microphone. The BA-55 is powered by a high-performance digital stereo amplifier, and features two custom-designed 6.5-inch speakers with an internal accelerometer switch to determine the orientation and sound output. When the amp is positioned upright (with the two speakers in a vertical position), sound is output in mono to maximise the distance of sound projection; when the amp is positioned on its side (with the speakers in a horizontal position), sound is output in stereo to enhance musical performances.
The BA-55 features an Intelligent Anti-Feedback function that automatically detects potential feedback problems, eliminating them before annoying howling sounds are produced. This is a huge advantage over manually adjusted volume levels, as it allows performers and speakers to place the BA-55 behind them and hear themselves clearly without experiencing feedback.
Also onboard the BA-55 is a line output for connecting to a larger amplification system, allowing a user to employ the amplifier as a personal monitor. This output can be used to connect to a recording device, which is great for capturing musical performances or public speaking.
Additional features include a handy auto-power off function and a convenient built-in storage space for the wireless microphone and other accessories. To suit professional and celebratory settings, the BA-55 Portable PA System will be available in both white and black.
