Mike13 Posted February 24, 2019 Share Posted February 24, 2019 Hi, hoping for some help with drop outs. I upgraded from the 200 to the Ultra, however the Ultra drops out completely after 20 minutes or less, requiring a re-boot. Both have a static IP, and the latest version of Eunhasu. It was originally connected by Ethernet over powerline, which worked fine with the 200, but when the Ultra kept dropping out, I switched to an airport express. Same story with the 200 working but the Ultra dropping out. Using Roon with Tidal and Spotify. I increased the sync and buffer settings. The Ultra came with the switch mod, which I removed to make sure that wasn't it. Is anyone able to help please? The Ultra gets very hot - I wonder if it could be this? Thanks Michael Link to comment Share on other sites More sharing options...
a.dent Posted February 24, 2019 Share Posted February 24, 2019 When you say dropping out, is it shutting down completely with the power light going off? My Ultra runs pretty hot but it never stops working. I have the clocked switch as well. If it's running really hot maybe it's over working. I'd try reloading the OS first. If no joy contact SoTM. 2 Link to comment Share on other sites More sharing options...

Thanks @a.dent . It just dissapears off the network and I can’t load the Eunhasu page. It doesn’t power off. Link to comment Share on other sites More sharing options...
a.dent Posted February 25, 2019 Share Posted February 25, 2019 Never seen that, sorry. As I said, I'd try reloading the SD card OS from the SoTM website. The Eunhasu OS seems to have lots of bugs. If no improvement I'd contact SoTM support. 1 Link to comment Share on other sites More sharing options...

What power supply are you using? Previously, was a Gieseler 1.5A power supply but now using a 4A PSU which makes the Ultra run cooler. What version are you running? Have you tried another version? http://docs.sotm-audio.com/doku.php?id=en/eunhasu/burn_sdcard_image Link to comment Share on other sites More sharing options...

Taken an hour to download 1gb to burn to SD. I’ve tried the latest, 4.56 by burning and by updating internally. With latest 4.56 burned to SD, it won’t even re-boot after setting a static IP address. Had to turn off then on and as soon as I select an audio zone in Roon, Eunhasu dissapears entirely and have to restart to get it back. Power supply is an SoTM sPS-500 running at 12. The Ultra is seriously hot. Link to comment Share on other sites More sharing options...

The Ultra is seriously hot. Try dynamic IP address. Also, run MPD, does it go down? Otherwise contact SOtM. The Ultra does get hot and at one stage, I contemplated changing it to 9V (requires someone who knows how). The Gieseler 12V 4A did the trick and it is more warm than hot. In theory, the sPS-500 at 12V will output just over 4A, so not sure what is happening there to cause the heating? Link to comment Share on other sites More sharing options...
Mike13 Posted February 25, 2019 Author Share Posted February 25, 2019 Completely shut itself down after second restart, and then was blinking green at the front which is new. I managed to listen to Roon Tidal for about a minute before it dropped out again. Link to comment Share on other sites More sharing options...
a.dent Posted February 25, 2019 Share Posted February 25, 2019 I run mine at 9V. Give that a shot. It's worth a try anyway. My understanding is there are 12V and 9V versions available. Maybe you got a 9V even if you ordered a 12V. I'm running the latest firmware and no problems at all now. It even turns off properly from Eunhasu now. There were some dropouts with an earlier one though. 1 Link to comment Share on other sites More sharing options...

The Ultra is sensitive to voltage (unlike standard) and I was told it could cause damage. And the recommendation is to get an authorised agent (Sublime in Perth) to change from the Ultra from 12V to 9V, if that is what you want.

a.dent Posted February 26, 2019 Share Posted February 26, 2019 @Mike13 My understanding is the 9V version is the standard one. 12V needs to ordered specially. Mine is a 9V version. Which one did you order? Link to comment Share on other sites More sharing options...

Mike13 Posted February 27, 2019 Author Share Posted February 27, 2019 @a.dent and @Snoopy8 thanks for the assistance here. Crisis averted. The issue was overheating as you suspected. It was placed against the wall of my cabinet and on top of the power supply. Running luke warm now. 1 Link to comment Share on other sites More sharing options...
gt1482 Posted February 27, 2019 Share Posted February 27, 2019 I remember it can be only a simple jumper change to change the input voltage (depending on the version of the sclk-ex board in the ultra). I still have the link in my notes: www.sotm-audio.com/sotmwp/english/sclk-ex-extra-power-input/ , which seems not working any more (strangely www.sotm-audio.com is also blocked by opendns).
