Roland CM30 Cube Monitor Amp

Versatile and portable — the new CM-30 CUBE Monitor delivers 30 watts of punch through a rugged, high-quality 6.5" coaxial two-way speaker. The CM-30 is built to handle a wide range of recording and mixing applications, but it can be used for live monitoring onstage as well. It can be easily and safely toted from location to location thanks to its built-in handle grip, protective metal grill cover, and cabinet corner protectors — features not found on any other monitors in the market.

30-watt 6.5" coaxial 2-way speaker with stereo preamp

Three input channels, with one XLR input for mic/line and two additional Aux inputs

Stereo Link function for stereo connection between two units, which allows a total of eight stereo inputs and two mono mic/line inputs

Metal grill cover, corner protectors, and handle grip for carrying the unit safely

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

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.
