Roland CM-30 CUBE Monitor at a Glance:
  • Ready to take out to any of your gigs
  • Sculpt your sound on the fly with onboard EQ
  • Plenty of inputs for your 2-track playback, microphone and more

Rugged, compact, and versatile
Like all members of the CUBE family, the CM-30 is a breeze to transport. From gig to gig, session to session, this amp travels light and performs big. It's built to withstand the rigors of the road, thanks to its metal grill cover and protective corner covers. While the CM-30 is well suited for home studio and monitoring applications, it can be used for live monitoring onstage.

Convenient front-mounted control w/ 2-band EQ
Sculpt your sound with the CM-30's onboard 2-band equalizer. Dedicated knobs are provided for adjusting low and high frequencies. As with all other controls, the equalizer knobs are conveniently located on the front panel for quick access.

Connectivity options galore!
Each CM-30 is equipped with three input channels, with one XLR input for mic/line, and two additional Aux inputs that support RCA pin (L, R) and stereo mini-phone connectors. So with one CM-30 you get four stereo inputs and one mono input. The Stereo Link function allows two CM-30s to be linked for true stereo output, which enables a total of eight stereo inputs, and two mono mic/line ins. The CM-30 offers more than enough inputs to simultaneously connect a microphone, a keyboard, a rhythm machine, and a CD player, or to function as a mini PA rig.

Can't go wrong with Roland

I've had experience with this monitor, which is why I bought it. I have a couple of Roland amps and use Boss pedals and they always do what you need them to do, without fail. This CM-30 is no exception.

great product at the right price,delivered in record time

I'm a Karaoke Host,do most of the singing myself.Always had a tough time hearing the music,especially at a low volume venue. I ordered this monitor and received it in 2 days,just in time for my gig that evening.Took it on the job ,connected it,and what a vast difference it made! At last, I could hear myself without cranking the mains up. I would recommend this product to anyone who needs a monitor I wish I'd had this product when I played in my band 40 years ago!

Great item

I am using two CM 30 for my electronic accordion. They fit onto a regular mic stand. You can also hook up a mic for announcements. I love the price too.

Roland CM-30 Cube Rocks!!

I use a Roland CM-30 Cube as my personal keyboard monitor within my multiple keyboard rig. The clarity and proximity of the monitor allows me to better hear my keyboard mix, the volume of each keyboard relative to the others, which helps me provide perfectly layered sounds. It's lightweight, compact. and easy to carry around. It's one of the best investments I've made!

Roland Does It Again

The Roland CM-30 Cube Monitor sounds great. It's amazing that such a full and rich sound is produced using such a small enclosure, but it does. I bought two, have wired them together, and have been using them as a mini-vocal PA. They're very versatile. In my gigs with acoustic guitar (also amplified by two Roland 40W amps), I can play most medium-sized rooms with no problem. These are solid, appear to be well-built, and are sure to work well for many applications. Thanks to Roland and Sweetwater!

Sweetwater Advice

AJ Becerra

I've have my Roland CM-30 CUBE Monitor for several years now, and it has been a staple in my garage for Driveway, jam sessions, you name it. It's one of the most durable, best-sounding little powered speakers out there. It has been in the extreme heat and cold (even had motor oil spilled on it!) and keeps on working day after day. I couldn't ask for a more reliable speaker!
