The Sonore opticalRendu project is an extension of the microRendu and ultraRendu projects that came before it. The design is inspired by audiophile gear and meant to bring grace and simplicity to a microcomputer. The original microRendu was very small and intended to be hidden out of sight behind your other gear. The opticalRendu and ultraRendu are in a larger case that beautifully integrates with your audio stack. The opticalRendu can still be powered by your favorite power supply or you can choose to upgrade to the Small Green Computer 7V Linear Power Supply. The opticalRendu has optical Ethernet input and USB-Audio output with all the connectors located on the rear of the unit for easy cable routing. The opticalRendu utilizes a new proprietary printed circuit board with only the essential components and many updates to match its optical designation. The best way to connect the opticalRendu to a USB device is via your favorite USB cable. The opticalRendu is easy to configure, accepts streams from various sources, and includes our latest version of our Sonicorbiter Operating System.



    • Mode #1 - SqueezeLite Output - This output works with any Logitech Media Server and compatible controllers. This output supports true gapless playback of PCM, DSD/DoP, and native DSD.
    • Mode #2 - ShairPort Output - This is an AirPlay emulator that utilizes streams sent to it from a compatible source. This output supports true gapless playback of PCM.
    • Mode #3 - MPD/DLNA Output: 
      Mode #3a - DLNA Output - This output utilizes streams from UPNP/DLNA servers and controllers. This output can be configured as an OpenHome renderer. This output supports true gapless playback of PCM, DSD/DoP, and native DSD. 
      Mode #3b - MPD Output - This output is intended to work with an SMB mount. This output supports true gapless playback of PCM, DSD/DoP, and native DSD. 
      Mode #3c - Songcast Output - This output accepts streams from your computer running Linn Songcast. The application is in Beta form.
    • Mode #4 - HQ Player NAA Output - This output utilizes streams from Signalyst's HQ Player running on your computer. Digital signal processing is performed by HQ Player and then asynchronously streamed to the Network Audio Adapter (NAA) output. This output supports true gapless playback of PCM, DSD/DoP, and native DSD.
    • Mode #5 - RoonReady Output - This output utilizes streams from Roon. This output supports true gapless playback of PCM, DSD/DoP, and native DSD.
    • Mode #6 - Spotify Connect Output - This output can be controlled by your computer or tablet running the Spotify application. This application is based on librespot which is an open source client library for Spotify. The application is in Beta form.
