miniDSP SHD Power¶
The miniDSP SHD Power offers a wealth of input-output options, network streaming services including Tidal, Qobuz, and Spotify, network players such as Roon, powerful back-end processing for subwoofer integration and active speakers and of course, two-channel (stereo) Dirac Live.
miniDSP cannot be held responsible for any damage that may result from the improper use or incorrect configuration of this product. Please read this manual carefully to ensure that you fully understand how to operate and use this product, as incorrect use or use beyond the parameters and ways recommended in this manual have the potential to cause damage to your audio system.
Please also note that many of the questions we receive at the technical support department are already answered in this User Manual and in the online application notes on the miniDSP.com website. So please take the time to carefully read this user manual and the online technical documentation. And if an issue arises with your unit, please read through the Troubleshooting section first. Thank you for your understanding!
miniDSP Ltd warrants this product to be free from defects in materials and workmanship for a period of one year from the invoice date. Our warranty does not cover failure of the product due to incorrect connection or installation, improper or undocumented use, unauthorized servicing, modification or alteration of the unit in any way, or any usage outside of that recommended in this manual. If in doubt, contact miniDSP prior to use.
The miniDSP SHD Power is one of a series of related products – the SHD Series. Each has the same processing capabilities, but different input-output capabilities. The other members of the series are:
SHD. The full-featured SHD is perfect for use in a high-end separates system, acting as network streamer and digital preamplifier with room correction. See the product page for more information.
SHD Studio. A compact all-digital input-output model, perfect for use in modern all-digital systems, studios, and professional applications. See the product page for more information.
The miniDSP SHD Power replaces multiple components in a conventional audio system -- preamplifier, power amplifier, network streamer, DAC and room correction are all bundled into a single affordable unit. Figure 1 illustrates how a miniDSP SHD Power can simplify your audio system.
Dirac Live room correction¶
The miniDSP SHD Power executes stereo (two-channel) Dirac Live® digital room correction, from Dirac Research. Dirac Live's mixed-phase filtering technology will improve the imaging of your system, minimize the effects of room modes and resonances, and improve dynamics and clarity.
To accomplish this, the Dirac Live software steps you through the procedure for taking measurements around your listening area. It employs a sophisticated analysis algorithm to make the optimal correction across the whole listening area, not just at a single point. You have full control over the target frequency response. Measurements are taken with the miniDSP UMIK-1 or UMIK-2 calibrated acoustic measurement microphone.
In addition to correcting magnitude response, Dirac Live® corrects the system's impulse response, which reflects how the system responds to a sharp transient such as a drumbeat. Reflections, diffraction, resonances, misaligned drivers, and so on, all combine to smear out the transient. Impulse response correction is a critical factor for accurate sound-staging, clarity and bass reproduction.
