miniDSP SHD Studio Audio Processor


miniDSP SHD Studio is a powerful and versatile digital audio processor incorporating Dirac Live®, the world’s premier room correction solution.

The UMIK-1 and UMIK-2 calibrated omnidirectional USB microphones are ideal for taking measurements with Room EQ Wizard or Dirac Live. UMIK-1 measures frequencies up to 24 kHz. With its larger capsule and higher sample rate, UMIK-2 reliably measures frequencies up to 96 kHz.

miniDSP SHD Studio is a powerful digital audio processor incorporating Dirac Live®, the world’s premier room correction solution. It packs the same powerful 2 in / 4 out audio processing capabilities as the full size miniDSP SHD, but without the analogue inputs and outputs.

The miniDSP SHD Studio 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 processor in the SHD Studio also runs Volumio, a popular open-source network streamer, providing web based access to music from sources as diverse as a USB stick to Internet Radio and Spotify.

The SHD Studio fits right into any digital processing path, with AES/EBU, S/PDIF, optical and USB audio inputs, and four output channels on both S/PDIF and AES/EBU.

The SHD Studio includes a suite of powerful but user friendly DSP audio tuning software, including ten band parametric EQ per output channel, crossovers up to 48 dB per octave, compressor / limiter and a flexible matrix mixer. Applications range from subwoofer integration to a two way active speaker. Outputs 3 and 4 also drive the headphone jack on the front panel for a uniquely flexible digital processing solution.

Frequently Asked Questions

miniDSP audio processors offer a lot of flexibility and not every possible use case requires taking measurements with a microphone. However, if you are going to use your miniDSP processor for room correction, subwoofer integration or as an active crossover for your speakers, then you are going to want to take some measurements using software like Room EQ Wizard (REW) or Dirac Live.

miniDSP’s UMIK-1 and UMIK-2 omnidirectional USB measurement microphones work perfectly with REW, Dirac Live and most other measurement software. Both models come with individual calibration files for horizontal and vertical placement, to provide highly accurate measurements in either orientation.

The lower cost UMIK-1 microphone has a sample rate of 48 kHz. This allows it to measure audio frequencies up to 24 kHz. It covers the entire audible band and provides more than enough bandwidth for subwoofer integration or room correction duties, where attention is mostly focussed on the low frequencies.

For those who want to understand the behaviour of their speakers or room beyond the audible band and into the ultrasonic, miniDSP offers the UMIK-2. UMIK-2 is equipped with a larger, more sensitive microphone capsule and a higher end analogue to digital converter, which provides a maximum sample rate of 192 kHz. This enables UMIK-2 to reliably measure frequencies up to 96 kHz (two full octaves more than UMIK-1).
