Roland Corporation U.S. announces that the BA-330 Portable Digital PA System (http://www.rolandus.com/products/productdetails.php?ProductId=1025
) is now available. Using Roland's superior battery technology, the BA-330 is the all-in-one portable PA solution for music venues, worship events, conferences, seminars, business meetings, and much more. The BA-330 has a six input, four-channel configuration, with two channels dedicated for microphones or instruments, and two other channels for standard 1/4" stereo inputs. Each channel has its own independent tone adjustment and effects switching for built-in effects, such as EQ, reverb, delay and widening. A Stereo Link function allows for a pair of BA-330s to work in tandem to provide an extra-wide stereo spread. Powered by a high performance digital stereo amplifier, the BA-330 features four custom-designed 6.5" stereo speakers and two tweeters, positioned for wide stereo dispersion. While the built-in tilt-back stand enables the unit to be angled up for better sound monitoring, the BA-330 also can easily be mounted on a speaker stand. The Roland BA-330 PA System features a unique Intelligent Anti-Feedback function previously unavailable in self-contained portable PA systems. During use, the BA-330 can automatically detect potential feedback possibilities and eliminate it immediately. This is a huge advantage over manually adjusting volume levels, as it allows performers to place the PA system behind them and easily hear themselves without experiencing feedback. Designed to deliver high-quality stereo sound for audiences of up to 80 people, the BA-330 can run on standard AC Power or eight AA Alkaline or Ni-MH rechargeable batteries. The switchable output power allows the user to switch between the maximum power and the energy-saving Eco modes to preserve battery life. The BA-330 is also amazingly efficient, delivering a sound pressure level of 109 dB, comparable to much larger mid-range sound systems. The BA-330 Portable Digital PA System is now shipping with an MSRP of $829.50.
