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.

Nice one powerful



Best vocal unit for its size & features


I had this unit for more than a year. It seems to provide better sound and separation than what you would expect from other units this size. With 8 AA batteries for a power source it is surprisingly versatile. Place it on a stand or on the ground, tilted or not, you get great sounding vocals. With two speaker out 1/4" out connections your are able to achieve super separation with a Left, Center, and Right coverage, or angle some of the speakers towards the players, and you have pretty good stage monitors. It has three power output levels, so a complete boost of the system can be achieved with one flip of a switch (eco, moderate, or full power). While it lacks a "Phantom " power for the mics, the adjustable power levels can easily handle the lower powered mics. The anti-feedback feature is always a welcomed feature and you will probably leave it on continuously. The additional channels, which include RCA and 1/8" inputs are very useful, and when used with portable media device like an IPad or a Fitbit watch allows you to have remote or Bluetooth functions and control. In short, while this unit falls short of a "large powerful stage PA system", it fulfills the small to medium size venues requirements with versatility, and clarity.

Awesome for my duo


I bought this for street performance, piano and vocal.... But I've started using it for my standard gigs. It is so convenient its rediculous. I'm thrilled. Suprising bass responce , good high end, on board effects are fine for my purposes. It's never going to be a full band PA. But it is a worthy step up from the smaller battery street amps. Well worth the money.
