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.

    Comments about Roland BA-330 Stereo Portable PA System:

    Have purchased two in last 24 months primarily for use with IPod or smartphone for music listening. Very clean, crisp, and punchy sound and simply plug into your IPod or phone for very impressive sound. Optional use with AA batteries will deliver 6+ hours of music at very loud volume. Not as lightweight as smaller portable PAs, yet the slight inconvenience of carrying is vastly outweighed by the sound the Roland delivers.

    Great Portable PA

    By REX

    from Tooele, Utah

    Comments about Roland BA-330 Stereo Portable PA System:

    4.5 stars. I bought one of these when they first came out. I wanted something for playing in small to medium venues and it has been outstanding. It plays as well on batteries as on power. The sound quality is great and I have yet to have to turn the volume up past about half way. The reason for docking it half a star is that the power switch sometimes does not want to engage, but it has never failed. I would definitely recommend it to anyone.

    Update to Seems to do the job

    Comments about Roland BA-330 Stereo Portable PA System:

    We opted for another system to do the wedding in the woods, this system lacked the bass - low end that the bride and groom were hoping for. I will be returning the unit.

    Seems to do the job

    By Marty

    from Central Iowa

    Comments about Roland BA-330 Stereo Portable PA System:

    I bought this to use at a wedding in the woods. We tested it out in the woods with a guitar and mic set up. It was really nice until we pushed the amp all the way to the max volume, then it got a bit "CRUNCHY" BUTT we didn't need it turned up all the way so it will work great for what we need. Did a test with it playing a iPod on medium volume and it played for 3 hours non stop on a fresh set of batteries (8 AA) and the battery level indicator still said it was fully charged! How Cool is that?? Effects are a bit cheesy but hey they are better than nothing, and you can apply them to one, all or none channels. Over all a great purchase, I hope they hold some value, after the wedding mine is going on ebay.

    Powerful Street Performance

    By lisa kovacik

    from Whitmore Lake, Michigan

    Comments about Roland BA-330 Stereo Portable PA System:

    I really love this amp. It will help me get my songs out to the world. I will be a one person band for a while. I can plug in my mp3 player with the original music from my songs (without vocals). Then I can plug in the mic, get the right mix of vocal and sound then turn the master volume up and start the show. I can also plug in the guitar and a few other instruments and do everything live. I can probably go on an on about this amp. It's everything I've hoped for in an amp. It looks good and weighs 30 lbs. I would recommend a fold up carrier to wheel this around to the locations you will be playing. I also recommend having two sets of batteries on hand at all times. I didn't know there was such a thing as a battery powered amp this powerful!! If you want more power and sound, you can get another Roland amp and connect the two. I would recommend this amp to any musician looking to play their music live. You will be heard!

    For my needs and purpose this unit works great so far

    By john edwards

    from Exeter, Rhode Island

    Comments about Roland BA-330 Stereo Portable PA System:

    Just got the unit yesterday. I needed something that ran on batteries so I could "take it to the streets", so to speak. Out of the box, read a few pages in the book, put the batteries in, plug in the mic, guitar, and MP3 player for my backgrounds and I was off and running. The sound for it's size is great. For what I do it seems to so far be everything I could want. Now it's to the streets and we'll see how I make out. Will write again to let you know.
