Description

miniDSP is proud to introduce the SHD (“Streaming High Definition”) digital audio processor incorporating Dirac Live®, the world’s premier room correction solution. A natural evolution and extension of our considerable experience with Dirac Live implementation, the miniDSP SHD heralds a new era in affordable yet powerful DSP-based network streamers. First and foremost, the SHD is a stereo Dirac Live room correction processor. Three digital inputs, two analog inputs and USB Audio enable the SHD to fit right into any modern audio system, while processed outputs are available as unbalanced and balanced analog as well as digital. Dirac Live calibration uses our popular UMIK-1 microphone and Dirac’s easy-to use calibration tool.

We have also added network streaming over Ethernet, using a dedicated quad-core ARM processor. Out of the gate, we are shipping 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. Finally, we’ve added a second pair of outputs and a suite of our powerful but user-friendly DSP audio tuning software – ten-band parametric EQ per channel, crossovers up to 48 dB/octave, compressor/limiter, and a 2×4 matrix mixer — for powerful audio system tuning in applications ranging from integrating a single subwoofer to a two-way active speaker.

Application Notes

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.
