The LHY Audio RPI Pro is a streamer based on the well-known Raspberry Pi CM4 module, integrating the RoPieee operating system for support of numerous streaming protocols: Roon Bridge, Airplay, Spotify Connect, Tidal Connect, Squeezelite, UPnP, NAA. Moode OS is also available for the RPI Pro if desired. In addition, it features a low-noise SC-OCXO clock system for ultra-precise signal processing. In terms of connectivity, it includes an HDMI video output, an isolated USB 2.0 output, SFP and RJ45 connectors, as well as a 10MHz external clock input via BNC and a TF card slot.
The LHY Audio RPI Pro features an optimized architecture with high-quality components, filtered power supply, and a precise clock for clean signal processing.

Inside the LHY Audio RPI Pro is a Raspberry Pi 4 and the ability to use two different operating systems by swapping the TF card. You can choose to use RoPieee, which directly integrates Roon Bridge, Squeezelite, Airplay, Spotify Connect, Tidal Connect, and UPnP, or opt for the MoOde operating system.

The ultra high-precision clock of the LHY Audio RPI Pro uses ultra-low noise OCXO oscillators. In addition, the Skyworks PLL chip, locked to the 10 MHz OCXO reference, generates multiple system clocks for the CM4, network, and USB subsystems. A BNC connector for an external clock is also available to further enhance your system.


The USB audio signal comes directly from the CM4 to avoid any degradation. An Analog Devices ADuM3165 chip also provides galvanic isolation for USB by eliminating any interference coming from the source.
The power supply of the LHY Audio RPI Pro features a high-current toroidal transformer with a 30VA Talema core and multi-stage EMI filtering. Advanced matrix filtering combines high-speed rectification with high-capacity premium capacitors, while three independent low-noise rails meet the demands of high-speed digital applications.
