 MG 5072

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 so-lution, and a full suite of miniDSP’s powerful but user-friendly audio tun-ing software. Dirac Live calibration uses our popular UMIK-1 microphone and Dirac’s easy-to-use calibration tool.

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 am-plifier, all packed into an unbelievably compact  metal enclosure.

We have also included network streaming over Ethernet or Wi-Fi, powered by a dedicated quad-core ARM processor. Out of the gate, we are ship-ping with Volumio, a popular open-source network streamer. Volumio gives you access to music files from sources as diverse as a USB stick, to files stored on your local network, to Internet Radio and Spotify.

The miniDSP SHD Series support a range of network streaming services, including Spotify, Tidal, and Qobuz. Even so, many of us still have a collection of music files that we want to play through an SHD Series processor. In a networked computer music system, a network attached storage (NAS) may be used for music file storage. While there are many manufacturers of NAS units, in this app note we will use a Synology as an example, as they are a popular and widely-available brand. If you use a different brand of NAS, the general techniques in this app note should still work. However, you will need to figure out the specific settings for your brand of NAS.
