Roland BA-330, Battery Amplifier, black

The portable 30-watt stereo P.A. system with battery operation! Roland presents a technical sensation: this complete and compact sound system delivers 10 hours of music for up to 80 listeners - using only 8 small AA batteries! Only Roland can offer such performance, thanks to years of research on the CUBES! This energy marvel provides everything necessary for professional sound reinforcement: crystal-clear and powerful stereo sound, a mixer for 6 input sources, an equalizer, effects, anti-feedback for microphones, a tilt bracket, a flange for a speaker stand, and a handy housing weighing only 13 kg. Just plug it in and you're ready to go!

Anti-Feedback Function: Anyone who has sung on stage knows how quickly feedback can occur. This is not the case with the BA-330: simply turn on "Anti-Feedback," and the critical frequencies will be 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) - these can be switched per channel. Additionally, there is a 2-band master EQ and an EQ for each channel.

Multiple Connection Options: Up to 6 instruments can be amplified simultaneously through the BA-330: 2 microphones (or mono instruments like guitars), 2 stereo instruments such as keyboards (mono is also possible), and 2 playback devices like MP3/CD players or drum machines. A recorder can be connected to the LINE OUT jacks; 2 footswitches control the effects and the MUTE function.

Stereo Link: With the "Stereo Link" function, two BA-330s can be combined into an even more powerful P.A. system with 12 inputs.
