SHD Series

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.

The miniDSP SHD 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 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/Tidal/Qobuz streaming.

The SHD has extensive connectivity options. Three digital inputs, two analog inputs and USB Audio enable the SHD to fit right into any modern audio system. The four-channel DSP-controlled outputs are available as single-ended (RCA) and balanced (XLR) analog as well as SPDIF digital.

In addition to Dirac Live, the miniDSP SHD includes a full 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 flexible 2x4 matrix mixer — for powerful audio system tuning in applications ranging from subwoofer integration to a two-way active speaker.

What's in the box?

  • Dirac Series Audio Processor — SHD DSP
  • USB Wifi 2.4GHz adaptor
  • Dirac Live 3.x license for full range correction (20Hz~20kHz) / Hardware Locked to SHD unit
  • UMIK-1 calibrated measurement microphone

NOTE: The UMIK-1/2 are measurement microphones approved by Dirac Research. Knowing the major effect a wrong calibration/measurement would have on the final results of Dirac Live tuning, we strongly recommend that you select a UMIK-1/2 microphone together with your platform for a plug&play experience leading to best results. Any issues related to 3rd party microphones such as ASIO/USB audio driver incompatibility/Latency problems or incorrect calibration process will not be under our support structure by our support team. 



The miniDSP SHD Series processors are certified Roon Ready players. This means that they are certified by Roon Labs to work seamlessly with the Roon software running on your PC, Mac, or Linux-based server! You can also use the Roon Remote for Android or iPhone/iPad for full remote control of your music playback with the miniDSP SHD Series.

Note: To use Roon, you will need to have a paid account with Roon Labs. Your miniDSP SHD Series includes a free two-month tria

Using the Surface Dial to control a miniDSP SHD Series processor

The Microsoft Surface Dial is a Bluetooth-connected physical control device. We decided to try using it as a remote control for the SHD Series processor. This way, you can have an actual physical volume control knob (and mute) that is remotely connected to the SHD Series processor! This app note describes how to do it.

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.

First, the conclusion: With the SHD and a March Audio p452 Purifi amp, I now have sound that surpasses my previous, twice-as-expensive integrated amp in every way. Compared to the megabuck offerings out there, the SHD offers exceptional functionality and flawless sound at a fraction of the cost. The long story: I just got back into the high-end audio game after being away for a decade. Formerly, I had USD $10,000 speakers and a $6000 integrated amp, both from technically savvy companies. At that point I was very pleased with the sound of my system. For various reasons, about 8 years ago I had to go to a desktop system, though, and for a while had fairly modest components. The system was fine, but I saw it as a stopgap system, not a long-term one. What motivated me to get serious about a desktop system was seeing the recent advances in amplifier and digital technology. I just purchased the SHD plus a March Audio Purifi amp, which both offer measured performance that ensures that they will never be the weak link in my system. I chose the SHD model because of its analog input (for when I set up my turntable again) and its ability to integrate two subwoofers (although in my small room right now, I only use one sub). I do wish that the SHD had a headphone amp, though, since I ended up having to buy a separate unit. Using Dirac Live was easy and the sound is better than anything I've had before. I'm using KEF LS50 Metas and an SVS Micro 3000 sub, both of which are "affordable" in the high-end context that I used to play in. With Dirac Live, what I noticed even more than the frequency response correction was the clarity of the sound and the seamlessness of the soundstage. I set up 3 Dirac curves with different bass responses so that I can get satisfying perceived bass at very low, low, and moderate levels (I don't listen at high SPLs). The fourth preset is
