  1. The CMOS battery might be a good idea. There might be a settings in the BIOS to toggle which allows the unit to boot. This is from memory...look for ACPI.

    Sonore microRendu

    DESCRIPTION The Sonore microRendu is an audiophile micro computer with Ethernet input and USB Audio output. The microRendu utilizes a propietary printed circuit board with only the essential components. The microRendu is small and light weight. Connect the microRendu directly to your USB device via a USB cable or hard adapter eliminateing the need for a USB cable. Don't let the size fool you though because it's been designed to take into consideration all that is important to USB Audio. The microRendu is easy to configure and can accept audio streams from several digital sources. What makes the microRendu different from a typical computer music server is that it's a purpose built audiophile device. The problem with computer music servers is that they all rely on mass produced motherboards designed for general purpose computing and are built to the lowest possible price point. The microRendu solves this problem by removing the consumer grade computer peripherals and optimizing power supplies where nessesary. The microRendu has been specifically built for processing USB audio perfectly. You can also combine the microRendu with an audiophile grade linear power supply to achieve the lowest possible noise floor. SELECTABLE OUTPUT MODES - Sonicorbiter 2.5 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.

    You guys haven’t been to Disney World....
  6. I agree with most of this. I know of one device that feeds the master clock back to the source. So for the rest of the i2s capable devices you are stuck with sending the best master clock you can to it in hopes that it will use it. For example: The PS Audio DS does not use the master clock and does its own thing internal. In our discontinued Rendu with i2s output the IO board would send a femto master clock to the DAC and also back to the i2s generator. It’s not what you describe as a best practice, but a hybrid. Anyway, the goal with external i2s, as I see it, is to try to improve on the DACs other inputs as they exist.

    If the DAC shows up in Apps / DAC Diagnostics go to Settings / Roon Ready and press Save.
  8. You should be able to see information on the video output. Try turning off the TV then turn it on and with the unit already connected boot it up.

    AudioLinux and NUC Troubleshooting and Tuning

    There is a very good write up in Italian (http://marcoc1712.it/?p=458) that explains the relationships of these settings in SqueezeLite. I prefer using ms settings because the duration of the buffer is consistent at all sample rates. Using bytes varies the buffer duration as the sample rate changes. At the end of the day the object of the game is to avoid buffer under runs or a buffer over runs. Having a large buffer increases the latency and having a large period makes the processor work more because it has to fill the bucket more often for any given buffer size. BTW This is all very easy to change on the Rendu series with a press of a button. On the Rendu series in Settings / SqueezeLIte if you just press Save you get SqueezeLite's default of 40 ms buffer and period of 4. Barrows has done some listening tests recently and prefers a 200 ms buffer and period count of 2. You can change these values at the risk of introducing dropouts and erratic playback behavior. Also, these values have limits as discussed in the write up. BTW these are just buffer settings between SqueezeLite and ALSA and not ALSA and your DAC...that is a whole other world of buffer fun which is DAC dependent.

    These units are primarily intended to stream music and not audio from video. Those delays are buffers that keep things working without dropouts.

    Sonore ultraRendu

    DESCRIPTION The Sonore ultraRendu project is an extension of the microRendu project that we launched over one year ago. The design is inspired by audiophile gear and meant to bring grace and simplicity to a micro computer. The original microRendu was very small and intended to be hidden out of site behind your other gear. The ultraRendu is in a larger case and perfectly matches the Uptone Audio UltraCap LPS-1 power supply. However, the ultraRendu can still be powered by your favorite power supply because it shares the same power specification as the original. The ultraRendu remains as an Ethernet input and USB Audio output, but all the connectors are now located on the rear of the unit for easy cable routing. The ultraRendu utilizes a new proprietary printed circuit board with only the essential components and some updates to match its ultra designation. The best way to connect the ultraRendu to a USB device is via your favorite USB cable. The ultraRendu is easy to configure, accepts streams from various sources, and includes our new operating system Sonicorbiter 2.5. SELECTABLE OUTPUT MODES - Sonicorbiter 2.5 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 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 a SMB mount. This output supports true gapless playback of PCM, DSD/DoP, and native DSD. This option requires a SMB share to mount your content in combination with the built in Drive Mounter application. Mode #3c - Songcast Output - This output accepts streams from your computer running Linn Songcast. The application is in Beta form.

    I just added Denafrips to the supported list under the PS Audio specification. There was an error in my i2s database which was making me doubt compatibility, but it seems fine. I'll fix my i2s database next.

    micro/ultraRendu - support thread

    The latest version of SonicOrbiter operating system is 2.7 and it has a lot of code for the Amanero. You have to use the correct Amanero firmware and how good it works is on them. I would look at the WaveIO USB interface.

    No...we use a different hub chip and a different Femto oscillator with it. The Femto oscillators is from Crystek and from the same series, but runs at a different rate.

    Yeah...that looks fine.
  18. We get a lot of questions about the differences between the products in the Rendu series. Here is a link to a simple cheat sheet to help you decide between the microRendu, ultraRendu, and signatureRendu. http://www.compare.sonore.us

    Quote of the day: This is uninitiated honest feedback from a customer... "I think, and my personal testing bears out, Roon sounds better when you have the Core on the network in a different room talking to a Roon Enpoint (I prefer the ultraRendu). The NUC is electrically much noisier than the microRendu or ultraRendu and that does not help sound quality." FYI I fixed a spelling mistake (in red) in the quote.

    I appreciate the feedback. I think you will be pleased with either the sBooster mk1 and mk2 so get what is really available to you. I prefer to keep things simple and ignore the recommendations of the .01%ers:)

    BTW the Teddy Pardo seems like a great supply...I just don’t have any experience with it.

    Some things can be hard to measure, but that trick is very easy to see it’s affects. Again, it’s a $50 power supply, so you have to put things in perspective. One thing for sure it gets the job done, it’s very reliable, and quite frankly not every situation requires a super power supply. Don’t mind me though...I’m just being pragmatic.

    No argument on that:) CIA does a nice job on that supply. Same goes for the SBooster power supply.
  24. vortecjr

    micro/ultraRendu - support thread

    Remember...I'm the first guy to say to use the best power supply you can afford. However, it depends on if you were using John's grounding trick, balanced DAC, or unbalanced DAC. It depends on your DAC's design...isolated or not, self powered, or powered by the Rendu. Just saying...I would not generalize these things.

    Sonore ultraDigtial

    Was it the video review...I can't search for key words on those:) He suggest it's the PS Audio spec. The i2s and master clock pins seem to match. However, pins 15 through 21 do not match and there is no telling what they do and how they affect things. Still worth a try IMO though.
