SHD Power

miniDSP is proud to introduce the latest member of the SHD (“Streaming High Definition”) processor family. As with all SHD Series processors, the SHD Power includes Dirac Live®, the world’s premier room correction solution, and a full suite of miniDSP’s powerful but user-friendly audio tuning software.

The SHD Power includes a 120W per channel low-distortion power amplifier for powering main speakers, and two additional analog outputs for connecting a subwoofer or subwoofers. With three digital inputs and high-resolution USB Audio, the SHD Power is the ideal modern integrated amplifier, all packed into an unbelievably compact metal enclosure.

The miniDSP SHD Power is a certified Roon Ready network player. Being Roon Ready means that miniDSP uses Roon streaming technology, for an incredible user interface, simple setup, rock-solid daily reliability, and the highest levels of audio performance, without compromise. The quad-core streaming processor in the SHD Power also runs Volumio, a popular open-source network streamer, providing web-based access to music files from sources as diverse as a USB stick to Internet Radio and Spotify.
