With eight AA batteries and a Roland BA-330 portable PA System you can now pump out 109dB (equivalent to a jackhammer).
The Roland BA-330 has four 6.5-inch and two tweeters and on the reverse you get a four-channel mixer with XLR, 1/4-inch, RCA, and mini jack inputs, and an effects section for adding EQ, re-verb, delay, or a stereo-widening effect.
It also has a stereo link feature which allows you to wire two of these bad boy BA-330 speakers together creating and awesome system.
If you’ve ever encountered embarrassing feedback onstage, and most of us have, you’ll be pleased to know that the BA-330 is equipped with Roland’s advanced Anti-Feedback technology. With a simple switch, the BA-330 automatically detects the howling point and eliminates feedback.
