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. The BA-55 offers global tone controls for quick sound adjustments and an echo effect that can be switched from the wireless microphone.
Powered by a high-performance digital stereo amplifier, the BA-55 features two custom-designed 6.5-inch speakers. These speakers use an internal accelerometer switch to determine the orientation and sound output. When the amp is positioned upright (with the two speakers in a vertical configuration), sound is output in mono to maximize the distance of sound projection, when the amp is positioned on its side (with the speakers in a horizontal configuration), 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 adjusting volume levels, as it allows performers and speakers to place the BA-55 behind them and easily hear themselves 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 alternately 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 both professional and celebratory settings, the BA-55 Portable PA System will be available in both white and black.
