We bought this system for smaller events that just needed a mic or two, and maybe a guitar or keyboard. Have only used it a few times, but so far have been very impressed. The quality is fantastic. It's very solid feeling.

The BA-330 speaker(s) have lots of virtues: volume, clean sound, portability! But, audio nuances from my connected keyboard are lost, in comparison to those subtle, but necessary tones coming from headphones I am using.

I am a wedding Musician/DJ. I purchased the BA-330 for a ceremony location that was too far away to run power to. It was more than loud enough for my classical guitar and recorded music to be heard by 115 people. I was so happy with it that I bought another one.

Pretty lightweight. Good sound. Definitely more sound from AC power than battery - but you can get pretty good battery sound for a couple hours. I'm keeping it. Kickback feature makes it a decent side fill monitor as a second function in a larger PA. Would also make a great keyboard amp IMO.

This Pa system is great for my use as a professional musician. I can use Vocals, Guitar, and 'Ukulele, all at the same time with beyond excellent sound quality. The fact that it runs on battery power as well as ac adaptor is awesome and allowed me to take outdoors gigs that require battery power.

Through battery use it will initially sound so that you might want to turn it down. With fresh batteries. Alkiline batteries initially last longer before it goes into won't get any louder mode!

Amazingly powerful for what it is. Very versatile and a lot of no hassle fun to use. Have you ever used a PA that never had any feedback at all ever no matter how you set it up or what you plugged into it ?

I perform solo acoustic shows, an average of 3 to 4 a week, and thought this would be a good alternative to having to carry a full PA system out to each show. This is a quality sounding PA, and is perfect for smaller venues.

Let me be the first to review the BA-330 that was delivered boxed-up nice and secure. I installed 8 used AA batteries (in a well designed solidly built battery compartment) just to see if it had life. To my surprise, it was loud with clean sound coming from the the 6 spkrs (stereo) in the cabinet.
