BOSS announces CUBE Street II, a battery-powered stereo amplifier for mobile music performers and anyone who needs high-quality sound on the go. Evolved from the best-selling Roland CUBE Street—and newly rebranded with the BOSS name—the compact CUBE Street II features two input channels for mics and instruments, onboard effects, looper and harmony functions, and more. The amplifier also includes support for the optional BOSS Bluetooth® Audio MIDI Dual Adaptor (BT-DUAL), a new product that allows users to wirelessly stream backing tracks and control CUBE Street II functions with a dedicated app for iOS and Android mobile devices.

First introduced in 2007, the groundbreaking Roland CUBE Street was an instant hit among mobile musicians. Offering a high-quality, battery-powered sound solution for street gigs and other intimate performing situations, it quickly became a mainstay in the busking world and continues to be used daily by performers everywhere. In 2014, the series expanded with the CUBE Street EX, a more powerful and feature-rich model for larger audiences. Starting with the CUBE Street II, all newly developed products in the CUBE Street series will carry the BOSS brand name.

CUBE Street II is even lighter and more durable than its predecessor, thanks to a modern ABS injection-molded cabinet design. The output power has also been doubled, providing 10 total watts of loud and clean stereo sound to cut through street traffic, train arrivals, and other noise challenges on the gig. In quieter situations, users can engage Eco mode to reduce the power and extend battery life.

With two ultra-versatile input channels, CUBE Street II supports all types of musicians and performers. The Mic/Instrument channel features a combo jack for either an XLR balanced mic or an instrument such as a keyboard or Roland’s Aerophone. Equipped with a standard ¼-inch jack, the Guitar/Mic channel provides plug-and-play sound for guitarists with seven acoustic and electric amp types, as well as settings for a line-level instrument or unbalanced mic.

CUBE Street II also includes many great features to take performances to the next level. Each channel provides three-band EQ and reverb, and there’s a chorus/delay effect on the Guitar/Mic channel. An automatic harmony function allows users to create impressive vocal harmonies based on the guitar chords they play or a preset key, and there’s also a built-in looper for creating backing tracks on the spot.

CUBE Street II helps performers reach both in-person and global audiences at the same time. Via i-CUBE Link and USB, users can send the amp’s audio output to video, livestreaming, or music production apps for on-the-spot capture. And while designed with performing musicians in mind, CUBE Street II excels in any situation that requires high-quality sound. It’s easy to move and sets up anywhere, making it perfect for speaking in presentations, workshops, and school events.

The optional Bluetooth® Audio MIDI Dual Adaptor (BT-DUAL) brings even greater creative power to CUBE Street II. Once installed, users can wirelessly connect a phone or tablet to jam live with backing tracks or play break music between sets. It also provides wireless connectivity for the CUBE Street II Editor, a free app for accessing extended functionality such as deep effects editing, battery level monitoring, Live Set creation, and much more.
