24-bit Digital Reference Monitor


The DS-30A 24-bit Digital Reference Monitors are the most affordable way to add pristine 24-bit/96kHz digital monitoring to your studio. These ultra-compact monitors utilize a 30-watt bi-amp design with custom crossover circuitry to deliver crystal-clear sound and flat frequency response. They’re the perfect match for Roland and BOSS digital studios, or for any application where a smaller high-quality monitor is needed.

Give Your Studio the Digital Edge

Whether recording with a stand-alone workstation or a computer-based system, your mixes are sure to benefit from owning a pair of digital reference monitors like the DS-30As. In fact, they’re so affordable, there’s no reason you shouldn’t be listening to your mixes the way they were meant to be heard: in pure 24-bit/96kHz quality without the line-loss or hum of analog cables.

30 Watts of Bi-Amplified Power

While compact in size, the DS-30As still sound impressive thanks to a 30-watt bi-amped design. Roland’s custom crossover circuitry distributes 20 watts to a 5” polypropylene woofer and 10 watts to a 1” soft dome tweeter. The result is super-flat response with minimal phase shift and distortion. There’s never been a better time to step up to digital monitoring.
