The CUBE Street EX from Roland is a compact, battery-powered portable amplifier/speaker combo that infuses the already popular mobile amp line with a performance upgrade that delivers extended projection, more channels, and enhanced versatility. Fifty watts of power and a stereo speaker system with dual woofers and tweeters provide clean sound for reaching larger crowds, while four independent channels offer connections for a variety of microphones and instruments.

Sound adjustment is available with separate EQ and reverb controls, and guitar tones can be dialed in easily with the onboard COSM amplifier simulations. Selectable power modes provide up to twenty hours of operation with eight AA batteries, while two units can be linked together for more sound coverage if needed. And with i-CUBE Link, an iPhone or iPad can be connected to play backing music and record the performances.
