Product Description

Details

Roland BA-55

The unique BA-55 portable PA provides self-contained, high-quality, and battery-powered sound reinforcement for any environment. It’s solidly built yet lightweight, and comes bundled with a matching wireless microphone for public speaking, singing, and many other events. Use the BA-55 portable PA as a small wireless PA system in school classrooms, business meetings, restaurants, weddings, intimate music venues, and more.

In a cool and convenient twist, the BA-55 portable PA contains an internal accelerometer sensor that automatically switches operation between stereo output (when positioned horizontally) and mono output (when positioned vertically). If you?re speaking and need maximum power and projection, use the vertical mono mode. For wide musical spread, turn horizontal. It’s that easy! The BA-55 portable PA is available in two colour choices, black (BA-55) or white (BA-55-WH). Choose one of these classic colours to blend best with your surroundings.

Easy 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.
