Second One

This is our second unit! Which should tell you how great it is! We use this mainly for wedding ceremony sites that don't have sufficient power. Because we have 2 of them we can link them up together with only using 16 double AA batteries. We can connect mics for the officiant, groom, book reader, guitarist and music for the walk down the aisle. One of our best products that we have found and we use it on the weekly basis. Never has anyone ever said that it wasn't loud enough. In fact, it perfect for transition from ceremony to cocktail hour within minutes. Best investment! Awesome product! Awesome service from Sweetwater!

Roland BA 330 Rules

Bought this unit for a music festival so we could play tunes from our playlists and to plug some acoustic guitars and mics and play a few tunes of our own. We were all blown away at the sound quality, ease of use and the battery life. I could not recommend this product more. I am buying another one so we can link them.

My first impressions of the BBA330

My first Impressions of the Roland BA330.. The unit arrived well packaged.. It appears very well made.. The AC power supply has a special connector to the amp...If you forget the power adapter and are on the job..good thing it works great on batteries.. The sound quality of the speakers is excellent..Crisp, clear mids and highs, a nice full rounded bass..the bass does not kick like some 12" and 15 " units, but is very even sounding..The bass is as good as most smaller units with 10 or 12 inch speakers...Like the Roland Cube 60 or 150... The combination of the 4-6 1/2" speakers and 2 tweeters..fill the room nicely..Roland's claim of 80-100 people is very accurate.. The unit is only 30 watts total output..15 watts a side....but it is amazing the quality and volume of the sound from this 29 pound amp. Rated at 109 db...will make most people shake their heads in disbelief.. Roland knows how to get big sound from low powered units.. This is a digital amp, that most likely relies on software aided sound technology.. The effects are decent, and very usable.. The anti feedback feature works well too.. The tone control also works well as does the master eq.. This amp is ideal for nursing homes, dinner parties, restaurants, even bars and clubs...If you are doing dance material..use the line out to another (larger powered speaker..for more bass)... The BA330 is a bit pricey, but sometimes you need to pay more for a high quality, feature laden sound system..and that is exactly what the BA330 is.... It is a keeper !!!!

Roland BA 330 Is Great!

I've got decades of performing experience and thousands of gigs under my belt and the Roland BA 330 is the best portable PA I've ever owned (or used). It's amazing when listening to internet radio too. It's $400.00 cheaper than anything that supposedly compares (and nothing does). Get one!

This is an incredible PA system in the portable battery powered category. I had this unit sitting on a picnic table playing outdoors with guitar and a CD backtrack. The sound output is excellent and it drew attention from people on how it was powered. Eight AA batteries and you are set for many hours of jamming. Typical Roland product, built solid / top quality. RCA hookups for AUX IN are a huge plus. Much better than 1/8” input jacks that you see on other company brands. You can also adjust your auxiliary input for bass & treble. Another huge plus! This BA 330 and other portable Roland products fill a niche. I can travel outdoors now without searching for an AC wall outlet. Perfect for the soloist... and with small AA batteries... Roland certainly optimized the technology for sound output. A very fine product. As always, Sweetwater delivered quickly and their sales department is the best.
