With its compact size and battery-powered operation, the Roland CUBE Street EX 4-Channel 50-Watt Battery-Powered Amplifier is a huge hit among traveling musicians. Now, the new CUBE Street EX infuses the popular mobile amplifier with a huge performance upgrade that delivers more projection, more channels, and more versatility. Fifty big watts of power and a stereo speaker system with dual woofers and tweeters provide clean, punchy sound for larger crowds, while four independent channels offer abundant connections for a variety of microphones and instruments. Detailed sound adjustment is available with separate EQ and reverb controls, and great guitar tones are dialed in easily with the onboard COSM amps. Selectable power modes provide up to 20 hours of operation with eight AA batteries, and two CUBE Street EX units can be linked together for more sound coverage if needed. And with i-CUBE LINK, you can even plug in your iPhone or iPad to play backing music and record your performances!

Impressive Performance Equivalent to a Small PA System

Equipped with 50-watt of stereo power, two eight-inch woofers, and two tweeters, the compact CUBE Street EX effortlessly projects your musical performances with clear, dynamic sound. Thanks to the unique new power circuitry developed by Roland, you can enjoy clean headroom and quality sound at a level that is impossible with any other battery-powered amp. The output power is adjustable in three levels: Maximum 50-watt, Normal 25-watt, and Eco 10-watt allowing you to conserve battery life in situations where you do not need maximum power. In Eco mode, eight AA Ni-MH batteries will last up to 20 hours! The CUBE Street EX can also be powered with the included AC adapter at gigs where electrical power is readily available.

Multiple Inputs to Support Any Performing Setup

The CUBE Street EX has an onboard mixer with four independent channels, providing ample connectivity options for all kinds of performers. Mic/Instrument and Mic/Guitar channels feature XLR/TRS combo jacks to support microphones or devices with 1/4-inch outputs, and each track is outfitted with its own three-band EQ and reverb effect for discrete sound shaping. The mono/stereo Line In channel is equipped with 1/4-inch jacks, while the Audio In channel provides a stereo 1/8-inch mini jack that supports i-CUBE LINK. If you fill up all the channels, you can use the rear-panel Aux In jack to connect an additional mono device if needed. The CUBE Street EX is a versatile amplifier that excels in various musical performance situations, accommodating vocalists, guitarists, synthesizers, electronic percussion, keyboards, drum machines, and backing tracks with ease.

Great Guitar Tones with COSM Amps and Effects

The CUBE Street EX makes it easy for guitarists to plug in and get pro sounds immediately. COSM tones for electric guitar include Lead, Crunch, and Clean, plus an Acoustic Simulator for extra versatility from a single axe. There is also an AC preamp optimized for acoustic/electric guitar and a convenient built-in tuner. Chorus/delay and reverb effects are available as well, and these can be turned on or off with optional footswitches while performing.

Jam and Record with i-CUBE Link and CUBE Jam

Roland’s innovative i-CUBE LINK interface lets you incorporate your iPhone, iPad, or iPod touch into your performances with the CUBE Street EX. i-CUBE LINK connects to your device’s audio jack with the included cable, providing two-way communication with your favorite music apps. Roland’s free CUBE JAM app is an ideal partner, allowing you to play along with music tracks from your iTunes library and record the CUBE Street EX’s output right back into the app. CUBE JAM also includes several useful functions for practice, jamming, and performing, such as independent pitch and speed adjustment and Center Cancel for minus-one playing and karaoke.
