SHD Power by miniDSP is an all-in-one device including a network streamer, a DAC, a DSP with volume control and a stereo amplifier with additional analog outputs to connect up to two active sub speakers simultaneously .

In other words, the SHD Power alone fulfills all the functions of a complete and autonomous High-Fidelity chain. Just connect  your speakers and you will obtain a compact, efficient and ready-to-use solution capable of playing your high definition digital audio files from a SPDIF / AES / EBU source, a USB audio source, a USB key, a storage device located on your local network (NAS), from a web-radio or a online streaming platform.

The device embeds a SHARC processor with Dirac Live and offers a very powerful acoustic correction solution in order to adapt to the specifics of your listening room and to compensate any imperfection likely to degrade your experience. This function requires a UMIK measuring microphone not supplied with the SHD Power unit.

Processeur DSP SHARC 450MHz

At the core of the SHD Power is a SHARC ADSP21489 audio processor with DIRAC Live. It is configured via USB and lets you to specify in advance up to 4 different digital signal processing profiles which can then be called quickly from the front interface or via a remote control.

Powerful and easy to use, the DIRAC Live solution offers a 10-band parametric equalizer per channel, a 48dB / octave crossover, a compressor / limiter, and a 2x4 mixing matrix with assisted self-calibration using a UMIK measurement microphone (essential for calibration and sold separately). This processor offers a complete and accessible workflow to measure and correct the acoustic imperfections of your listening room.

Two digital outputs on AES / EBU connector make it possible to get the digital signal just after the SHARC processor to send it to a second external DA, which considerably extends the integration capabilities of the miniDSP SHD Power.

It is a bidirectional USB interface. It is therefore also possible to recover the digital signal processed and separated up to 4 channels directly on your computer for occasional use in acquisition.

A second USB-A input is available on the connector panel. The latter works as a USB host and can directly access audio files stored on a USB key or an external hard drive to connect storage devices on the fly.

 Class D TPA3255 2x120W Amplifier

The SHD Power has an amplified analog output to directly connect your passive speakers. This output works thanks to a TPA3255 class D amplification chip and can develop up to 2x120W RMS under a 8 / 4 Ohms load.

The integrated amplifier has a nice signal-to-noise ratio of 110dB (@ 1kHz A-weighted, 120W & 8Ω) with a THD + N <0.03% (4Ohms, f = 20Hz-20kHz, 60mW-100W) / <0.07% (8Ohms , f = 20Hz-20kHz, 60mW-100W) and a crosstalk of <-95dB (1kHz).

Preinstalled Volumio

In addition to the Dirac Live interface accessible from your computer, the unit is delivered with a Volumio distribution preinstalled. This software has all the tools to easily control all the device's network player functions thanks to a web interface which is accessible from your local network.It is for example possible to use the Web interface with a smartphone / tablet / computer to explore and select the audio files contained on a USB key connected to the SHD Power, to access audio files stored on a NAS, or to access an online streaming service.
