DM-20

Digital Stereo Micro Monitor

DM-20
Discontinued

The DM–20 Digital Stereo Micro Monitors bring 24-bit/96kHz digital monitoring to a super-affordable price and ultra-compact size. The DM-20’s independent transformers and power amps crank out 20 watts per side. Perfect for use with Roland/BOSS digital studios and instruments, computer-based setups and more.

Compact Monitors with Sleek Cabinet Design

Whether placed in a studio or computer-based setup, the DM-Series’ new black finish and real wooden cabinets give these speakers a look befitting of monitors costing much more. But it’s not just about looks; the cabinet is also designed to perfectly compliment the amp and speakers, resulting in the best possible sound.

24-bit/96kHz Digital Inputs

Thanks to their coaxial and optical digital inputs, the DM-10 and –20 eliminate the line-loss and hum that can occur when using analog cabling—resulting in a more accurate reflection of your mix. These 24-bit/96kHz digital inputs are ideal for use with Roland and BOSS digital studios, or for connecting a variety of digital gear including a computer sound card.

Convenient Front-Mounted Controls

No one likes to reach around to the back of a speaker. That’s why Roland placed all the essential controls on the front panel. Now you can adjust each input’s volume—along with the Treble and Bass—right from the front of the speaker. The power is also located on the front, along with a stereo headphones jack for silent monitoring.
