Whether battery powered or plugged in, the BA-330 delivers high-performance sound that defies its size. Its digital stereo amplifier drives four 6.5" stereo speakers and two tweeters, positioned for wide stereo projection. It’s the ideal, all-in-one portable PA solution for small music venues, worship events, conferences, seminars, business meetings and much more.

Advanced Anti-Feedback

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.

Onboard FX

Three high-quality effects are built-into the BA-330: Reverb, Delay, and Wide. The effects can be turned on/off independently for each channel. In addition, a master 2-band EQ is provided as well as EQ control for each channel.

Versatile Input

A wide range of instruments, microphones, and devices can be plugged into the BA-330 simultaneously. Two mono channels are provided for microphones or line-level instruments (XLR and 1/4” jacks), two stereo channels are provided for stereo instruments (1/4” L/R jacks), and a stereo Aux input channel is provided for CD players and other devices (RCA and TRS jacks).

Stereo Link

The BA-330’s Stereo Link jack lets you cascade two units, giving you twice as many channels and the ability to position the two units on opposing sides of the stage.
