Roland Cube Street Ex - Battery-Powered Stereo Amplifier!

The compact, battery-powered Roland CUBE Street is a top seller among street performers. With the new CUBE Street EX, the popular portable amp gets an upgrade with more power, more channels and greater versatility. The stereo amplifier delivers up to 50 watts and features a 2-way playback system (with separate bass and treble speakers) to ensure a clear, punchy sound for larger audiences. Four independent channels provide plenty of inputs for a wide range of microphones and instruments.

Equalizer and effects let you shape the sound precisely. Great guitar tones are guaranteed with the built-in COSM amp models. Switchable power settings allow up to 20 hours of operation on 8 AA batteries. And if you need more: two CUBE Street EX units can be linked via Stereo Link to form a compact PA. Via i-CUBE LINK you can connect your iPhone or iPad to play back tracks or record your performance!

Impressive! Sounds Like a Small PA

Equipped with 2 x 50-watt stereo power, two 8" speakers and two 2" tweeters, the compact CUBE Street EX effortlessly delivers a clear and dynamic sound for live gigs. Thanks to Roland’s new power system, the CUBE Street EX produces a sound quality that stands out among battery-powered amps. The output power can be set to three levels: Max (50 W), Normal (25 W) and Eco (10 W). This lets you conserve battery life when you don't need full power. In Eco mode, 8 AA Ni-MH batteries can last up to an incredible 20 hours! When mains power is available, the CUBE Street EX can also be powered with the supplied AC adapter.

Versatile Connections for Any Setup

The CUBE Street EX features an onboard mixer with four independent channels and connection options for virtually any type of live performance. Mic/Instrument and Mic/Guitar channels use XLR/phone combo jacks for miking or for devices with line outputs. Each channel has its own 3-band EQ and a reverb effect for separate tone shaping. The mono/stereo line-in channel uses 6.3 mm phone jacks, and the audio-in channel has a stereo mini jack that also supports i-CUBE LINK. If all channels are in use, an additional mono device can be connected via the AUX-in.

The Versatile CUBE Street EX Is Ideal for Many Live Performance Setups. Here Are Just a Few Examples:

  • Vocals, guitar, synthesizer and electronic percussion
  • Two singers, keyboard and backing tracks
  • Electric and acoustic guitar with drum machine
  • Vocals, guitar, drum machine and backing tracks

Great Guitar Sounds with COSM Amp Models and Effects

The CUBE Street EX makes life easy for guitarists. Plug and play. Pro-quality COSM tone generation for electric guitar with lead, crunch and clean sounds, plus acoustic simulation for more versatility when using single-coil pickups. The AC preamp is optimized for acoustic and electric guitars. The built-in tuner is also very user-friendly. Chorus/Delay effects can be switched on/off via a separate footswitch.

Jam and Record with i-CUBE LINK and CUBE JAM

Roland's innovative i-CUBE LINK interface connects your CUBE Street EX with an iPhone, iPad, or iPod touch. Connect the supplied cable with the audio jack and you get a bi-directional link to your favorite music app via i-CUBE LINK. Roland's free CUBE JAM app is a perfect tool to accompany your favorite iTunes tracks. You can record the CUBE Street EX output directly with CUBE JAM. CUBE JAM includes many useful practice and performance features, such as independent pitch/speed control and a center-cancel function for backing tracks and karaoke.

Stand Flange and Sound Expansion

Placed flat on the ground, the CUBE Street EX sits slightly tilted for excellent monitor sound—on the street and on stage. If you need wider sound coverage for larger audiences, the amp can be mounted on the optional ST-A95 speaker stand. With the convenient Stereo Link feature and two CUBE Street EX units, you get a powerful stereo PA system with a total of eight separate inputs.

Lightweight and Rugged

Like all amps in Roland’s updated CUBE series, the CUBE Street EX is extremely rugged. The durable injection-molded (ABS resin) cabinet has been specially optimized through extensive durability testing for reliable outdoor use. But the CUBE Street EX is not only tough—it’s also surprisingly light, making it easy to carry from gig to gig. The optional CB-CS2 carrying case has a comfortable shoulder strap and accessory pockets. It’s water-resistant and protects the amp from moisture on the road.

Sound and performance surprisingly good

High praise for sound and performance.
Pre-selection of the three outputs also works.
At full power, my room almost flies around my ears. No really, you can't turn it up all the way. Hammer loud. Certainly stands up to drums.
The controls feel great.
Amps and effects sound good.
Lots of inputs.
The option of a guitar input without amp and effects is great for me.
This allows me to play my Mooer GTRS WING 900 modeling guitar without having to run it through an effects chain twice.

So really a recommendation to buy.

Small disadvantage. The box is relatively heavy and large. You probably need a trolley or something similar to get everything into the pedestrian zone.

Also...why doesn't it have Bluetooth?

I was looking for an amplifier with enough power that you can operate with normal batteries. Also at home you can easily rehearse without a power outlet.
Many connections that offer enough possibilities. No phantom power, ok, but for that there are mixers with 3x9V if needed.
Price is a little high but there's a lot for the money.

This amplifier I now have twice, joy. Was me when I bought the first but absolutely clear. The possibility of these two to connect to a PA. The part sounds too good even with the smallest setting. When using the full 50 watts, my glasses have clinked. The only thing I really miss is the possibility to connect a USB stick and play MP3. That would have been a really useful feature in an amp for street musicians. But that is complaining on a high level. Kirstein has been my supplier several times, so I can only praise them here as well. My first Roland I bought somewhere else, here now because Kirstein gave me 10 Euro for my birthday. Thank you very much for that.
