The Roland Cube Street EX is compact in size and able to be completely battery powered. Building on the success of Roland's CUBE Street among traveling musicians now, the new CUBE Street EX takes this popular mobile amp and gives it a boost. With a power and performance upgrade that gives you more projection, more ins and outs and, ultimately, more versatility. 50 big watts of power and a true stereo speaker system with dual woofers and tweeters that provide clean, clear, punchy sound for bigger crowds and wider streets. With four independent channels that offer just about every connection you could want you can plug in a variety of mics and instruments to get your gig rolling. Separate EQ and reverb controls let you dial in things to how they needs to be and awesome guitar tones live in the on-board COSM amps. Depending on the power mode selected this amp will run for up to 20 hours of operation, on just eight AA batteries. Fifty watts still not enough? You can even chain two CUBE Street EX units together! Or just give that a go if you want to fill a little more space with ultimate sound coverage. And with i-CUBE LINK, you can even plug in your iPhone or iPad to play backing music and record your performances.
