About the SHD
The miniDSP SHD is a sophisticated Streaming High Definition (SHD) network player and preamplifier designed for high-resolution audio processing and playback. It features a 32-bit Analog Devices SHARC ADSP21489 DSP running at 450MHz with an internal sample rate of 96kHz and supports input sample rates up to 192kHz. The SHD is certified Roon Ready, enabling seamless integration with Roon streaming technology for an intuitive user interface and reliable performance. It also supports Volumio audiophile streaming, AirPlay, and Spotify, allowing playback from network sources, USB drives, and Internet radio. Connectivity includes three digital inputs (AES/EBU, SPDIF, TOSLINK), two analog inputs, USB Audio with asynchronous XMOS support up to 192kHz, and Gigabit Ethernet. Outputs include four DSP-controlled channels available as single-ended RCA, balanced XLR, and SPDIF digital outputs, facilitating flexible system integration including active speaker and subwoofer management. The SHD supports Dirac Live room correction across all inputs and sources, enhancing sound quality by compensating for room acoustics. Additional DSP features include matrix mixing, parametric equalization, crossover functionality, volume control, compressor/limiter, and mute. The device is controlled via a USB 2.0 interface for configuration and streaming, with a driverless setup for Mac OS X and ASIO drivers for Windows. The front panel features a black and white OLED display and an IR remote control is included. The SHD Plugin software allows detailed configuration such as input source selection, speaker impedance settings with over-current protection, channel gain adjustments, parametric EQ, crossover settings, and routing of inputs to outputs. Outputs 1 and 2 are typically assigned to speakers, while outputs 3 and 4 serve line-level subwoofer outputs. Digital outputs mirror these assignments. Overall, the miniDSP SHD is a versatile and powerful DSP-based streaming preamplifier suitable for modern high-fidelity audio systems requiring advanced room correction and flexible connectivity.
