RPi - Streamer & Bridge

Description

LHY Audio RPi Pro – High-precision streamer and digital bridge

El LHY Audio RPi Pro It is a high-performance streamer and digital transport designed to extract maximum sound quality from network music services. Based on the powerful Raspberry Pi Compute Module 4, combines a flexible computer architecture with proprietary High-End audio solutions.

Your network connection using Ethernet RJ45 or SFP optical fibre allows the reduction of electrical noise input coming from the router, the switch and the rest of the installation. The signal is delivered to the DAC via an output native and isolated USB 2.0, avoiding unnecessary conversions and preserving the integrity of the digital data.

 

One of its most prominent features is its advanced clock system, consisting of an oscillator Ultra-low phase noise SC-Cut OCXO and a PLL circuit Skyworks Si5381. Furthermore, it incorporates a BNC input to connect an external master clock from 10 MHz, with automatic reference selection.

Power supply has also received special attention. The RPi Pro uses a toroidal transformer of 30 VA, EMI filtering, high-speed rectification and multiple independent regulation stages. In this way, the processing, network and USB output sections receive stable, extremely low-noise power.

Compatible with Roon, HQPlayer NAA, UPnP, Spotify Connect, Tidal Connect, AirPlay and Squeezelite, the RPi Pro allows the operating system and playback software to be tailored to each user's preferences. It can work with solutions such as RoPieee, Volumio, Moode or PiCorePlayer.

A solution particularly suited to those who already have a quality DAC and are looking for a silent, stable network transport prepared to play high-resolution music up to native DSD512.
