For those who like getting loud in places where power outlets are hard to come by, the Roland BA-330 delivers all the comforts of a full-fledged stereo P.A. system using just eight AA batteries.

Just how loud are we talking? Cranked all the way up, the BA-330 can hit a 109dB sound pressure level--roughly the equivalent of standing next to a jack hammer. The eight AA batteries can deliver up to 10 hours of continuous power, although probably not at full blast (plug-in AC power is also available).

The front of the system offers four 6.5-inch and two tweeters, all wired for stereo. On the back, you'll get a four-channel mixer with XLR, 1/4-inch, RCA, and minijack inputs, and an effects section for adding EQ, reverb, delay, or a stereo-widening effect. If 109dB of ear-melting sound just isn't enough, a stereo link feature allows you to wire two BA-330 speakers together.

Of course, at around $829, street musicians are going to have to hustle hard to get their hands on this thing. Consider this your head start, since it's not due out until November.
