Roland BA-55 Battery Powered Portable Amplifier, White Overview
Versatile, Portable PA with a TwistEasy to Use and Transport
With the BA-55 portable PA, ease of use is the name of the game. There's nothing complicated about it: just turn on the wireless microphone and/or plug in your instruments, set the volume to the desired level, and go. That's it! The BA-55's automatic anti-feedback system blocks acoustic feedback without interrupting your audio. For easy transport, the BA-55 has a convenient built-in storage compartment to house your wireless microphones and accessories.
Multi-Purpose PA
The BA-55 portable PA lets you enjoy great sound anywhere, indoors or outdoors. Use batteries or the included AC adapter for the ultimate in convenience and flexibility' For speech, position the BA-55 portable PA vertically and the internal accelerometer will automatically switch operation to mono mode for maximum sound projection. For music, place the BA-55 portable PA horizontally and it will automatically switch to stereo mode; this is perfect when using MP3/CD players at dance parties, etc., or any application where wide sound projection is desired.
Built-In Echo/Reverb
Onboard the BA-55 portable PA is an Echo/Reverb that sounds great and is easy to use, with a single knob that adjusts both the effect type and amount. When you turn the knob from the Off position to 12 o'clock, you activate a natural plate-reverb-type effect that adds a natural ambience to your voice and/or instruments. When you turn from the 12 o'clock position to maximum, you switch to a repetitive echo-type effect. The echo/ reverb can also be turned on and off from the included DR-WM55 wireless microphone for convenient remote control.
Wireless Microphone Included
The BA-55 portable PA package includes a high-quality wireless microphone (DR-WM55). Designed specifically for this system, the mic has Power On/Off and Echo On/Off switches. The Echo switch is linked to the BA-55's Echo/Reverb effect, which lets you enable and disable it directly from the mic. This is a very handy feature, allowing the effect to be quickly turned off when speaking or making announcements, then easily switched back on for singing
