The BA-55’s automatic anti-feedback system blocks acoustic feedback without interrupting your audio.

MULTI-PURPOSE PA The BA-55 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 vertically and the internal accelerometer will automatically switch operation to mono mode for maximum sound projection. For music place the BA-55 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 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 (see below). WIRELESS MICROPHONE INCLUDED The BA-55 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.
