Alto Professional BUSKER Portable Active Loudspeaker

Alto Professional BUSKER Portable Active Battery-Powered Loudspeaker

Alto Professional BUSKER is a compact and powerful PA system that offers the freedom to perform anywhere. The device features an integrated rechargeable battery, providing up to 24 hours of operation in "Eco" mode (up to 20 hours in standard mode). The loudspeaker boasts 200 W (Peak) power, delivered by a 6.5-inch woofer and a 1-inch tweeter.

One of the biggest advantages of this model is its integrated 3-channel mixer with professional Alesis effects (Reverb, Delay, Chorus, Flanger), designed to enhance vocals and instruments. The first channel has 48V phantom power, allowing even studio condenser microphones to be connected. The third channel is for Bluetooth 5.0 music streaming or wired AUX connection.

Control is made easy with the free "Alto App" (iOS/Android), which allows remote adjustment of settings, effects, and EQ. Additionally, the TWS function allows two "Busker" loudspeakers to be wirelessly connected into a stereo system. The loudspeaker's design allows it to be placed vertically, angled as a monitor, or mounted on a stand.
