Roland BA-330 Portable Stereo PA System

The Roland BA-330 is a portable stereo PA system designed for small live performances, presentations, worship services, meetings, and events where a compact all-in-one sound system is useful. It combines amplification, speakers, a mixer, effects, and multiple input options in one enclosure. This helps reduce the need to carry separate powered speakers and a small mixer for straightforward setups.

Its digital stereo amplifier is rated at 15 watts per channel and drives four 6.5-inch speakers plus two tweeters. The multi-speaker layout is designed for wide stereo projection, making it suitable for performers and presenters who need sound coverage from a single portable unit. Roland specifies the BA-330 for audiences of up to 80 people.

Two mono channels accommodate microphones or instruments through XLR or 1/4-inch TRS inputs, while two stereo input channels accept keyboards, music players, and other line-level sources. A separate AUX IN section supports both stereo mini and RCA connections. Individual channel tone, volume, and effect controls help tailor connected sources without requiring an external mixer.

The BA-330 includes onboard EQ, reverb, delay, stereo wide processing, and Roland's Intelligent Anti-Feedback function. These tools provide practical control when using microphones in close-range portable PA applications. A master low and high EQ section lets users make overall tonal adjustments to suit the room or program material.

For flexible placement, the BA-330 can operate from its included AC adapter or eight AA batteries. Stereo Link connections allow two BA-330 units to be linked for additional channels and left/right placement across a wider performance area. Line outputs also make it possible to feed another sound system when expanded coverage is needed.

Design & Installation

The BA-330 is a self-contained portable PA enclosure with an integrated control panel, four 6.5-inch speakers, and two tweeters. Its 13.8 kg (30 lb 7 oz) weight and upright cabinet format support transport between rehearsals, presentations, and small event spaces. Front-panel channel and master controls keep common adjustments accessible during use.

Connect microphones or instruments to CH 1 or CH 2, connect stereo instruments to CH 3/CH 4 or CH 5/CH 6, and use AUX IN for compatible music players. Power the unit with the supplied AC adapter or install eight AA batteries for portable operation. For larger setups, use the Stereo Link jacks with a second BA-330 or send audio from the LINE OUT jacks to another compatible sound system.
