The portable Roland BA-330 Stereo PA System delivers high-performance sound that defies its modest size, whether operating with battery power or plugged in. The Roland PA's digital stereo amplifier drives four 6-1/2" stereo speakers and 2 tweeters, positioned for wide stereo projection. The BA-330 is an ideal, all-in-one portable PA for small music venues, worship events, conferences, seminars, business meetings, and much more.

Powered by AC power or 8 AA batteries, the all-in-one Roland digital PA system is suitable for use anywhere. The PA system's powerful high-quality stereo sound supports music for audiences of up to 80 people. No setup is required, just plug in and go. The Roland BA-330 has 3 high-quality effects built in: Reverb, Delay, and Wide. The effects can be turned on or off independently for each channel. In addition, Roland provides a master 2-band EQ and EQ control for each channel.

You can plug a wide range of instruments, microphones, and devices into the Roland BA-330 simultaneously. Two mono channels are provided for microphones or line-level instruments (XLR and 1/4" jacks), 2 stereo channels are available for stereo instruments (1/4" L/R jacks), and a stereo aux input channel is included for CD players and other devices (RCA and TRS jacks).

Cascade 2 Roland BA-330 units using the Stereo Link jack—giving you twice as many channels and the ability to position the 2 units on opposing sides of the stage. The stereo aux input has a dedicated volume-control knob for ultimate control of your sound.

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. A built-in tilt-back stand enables optimal monitoring angle, and Roland includes a speaker stand adaptor for mounting the BA-330 PA system on a standard speaker stand.
