Notes: Play anywhere, any time

The Sheeran Special Edition Busker provides pristine audio and convenient portability for on-the-go performers across all genres, skill levels, and professional pedigrees.

Built for musicians looking to captivate audiences in public spaces, this all-in-one powerhouse of a PA speaker will not only broadcast your performance with precision and power but does away with a clunky arsenal of equipment, giving you the ultimate mobility and flexibility when performing.

While Ed Sheeran's career has taken him from busking in British train stations to selling out stadiums worldwide, there is a universal throughline that any impassioned performer can relate to-share your music with the world, anywhere, anytime. Sometimes, in order to let that spark burn as brightly as possible you need the right tools for the job. Thanks to its numerous sonic capabilities and lightweight design, the Sheeran Special Edition Busker provides on-the go musicians with the gift of stressing less and playing more.

Key features

Powerful and Portable

Thanks to 200W of raw sonic power, the Sheeran Special Edition Busker provides the highest calibre of audio reproduction in the portable speaker space. DSP processing and a built-in 3 channel mixer allows users to fine tune their live sound with professional precision.

In addition, the Busker has individual modes that will accommodate the sound output depending on how the device is oriented for your performance - monitor style in vertical and horizontal positions or conveniently pole mounted on a tripod or subwoofer.

Street Performance, Studio Quality

Long gone are the days of having to sacrifice sound quality in a live setting-the Busker features a built-in three channel mixer with on board Alesis FX that offers studio quality reverb, delay, modulation and more.

Style And Substance

When it comes to looks, the Sheeran Special Edition Busker is a standout in its class. Thanks to an eye-catching titanium grey grille and iconic Sheeran Infinity badge, this PA is as stylish as it is capable.

Bluetooth Connectivity

Bluetooth 5.0 allows endless possibilities-fire up backing tracks from your preferred streaming service, connect a second Busker for stereo monitoring, and even control the mix and EQ from your mobile device.

The Alto Pro App

No need to reach down and adjust settings during your performance - the Alto Pro App for iOS and Android gives you control over Busker's parameters directly from your mobile device.

Complete On-The-Go Workstation

Pair the Busker with the Sheeran Looper+ and command the stage just like Ed! With this highly intuitive, user friendly and entirely battery.
