The Portable 30-Watt Stereo P.A. With Battery Power!
This complete and compact PA delivers 10 hours of music for up to 80 listeners — using only eight small AA batteries!!! Only Roland can — thanks to years of research on the CUBES — offer this kind of performance! This energy marvel gives you everything needed for professional sound reinforcement: crystal-clear, powerful stereo sound, a mixer for 6 input sources, equalizer, effects, anti-feedback for microphones, tilt bracket, flange for a speaker stand, and a handy cabinet weighing just 13 kg. Plug in and go!
Anti-Feedback Function
Anyone who's ever sung on stage knows how quickly screaming feedback can occur. Not with the BA-330: just switch on 'Anti-Feedback' and the critical frequencies are analyzed and suppressed.
Built-In Effects
Three high-quality effects are built in: reverb, echo, and the WIDE effect (for an extremely wide stereo image) — selectable per channel. There's also a 2-band master EQ and an EQ for each channel.
Many Connection Options
You can amplify up to six instruments at once with the BA-330: 2 microphones (or mono instruments like guitars), 2 stereo instruments such as keyboards (mono possible), and 2 playback devices like MP3/CD players or drum machines. A recorder can be connected via the LINE OUT jacks; 2 footswitches control the effects and the mute function.
Stereo Link
The 'Stereo Link' function lets you combine two BA-330 units into a more powerful P.A. with 12 inputs.

If now the power duration is still right that's top.
Also sound control and the other leaves nothing to be desired.
In the weight class I know nothing better.
We will use it in the summer.
Bye fork things and sockets.
