Schafheide Posted October 11, 2022 Share Posted October 11, 2022 All of a sudden there is no sound coming from the RH channel of my Mini (connected to network via ethernet cable). All other components in the chain do check out. Is this easily fixed or is the Mini now a brick? TIA Link to comment
Schafheide Posted October 11, 2022 Share Posted October 11, 2022 Panic over - somehow, in Pipeline settings, the Gain unit had changed from dB to Linear. How? Link to comment
Schafheide Posted October 11, 2022 Share Posted October 11, 2022 I meant to say that the working channel showed dB, but the "dead" channel showed Linear. Link to comment
Miska Posted October 11, 2022 Share Posted October 11, 2022 Yeah, having gain value of 0 and linear means silence will output. It could happen if you accidentally touch scroll wheel or similar (two fingers on touch pad) while mouse pointer is on top of the selection list.

Badge Posted October 12, 2022 Share Posted October 12, 2022 I am running a Mini M1 with Roon and HQP which uses an SoTM SMS-200 Ultra an a NAA. The NAA then sends signal via USB to SoTM tx-USBUltra USB reclocker, then USB to Aqua La Voce S3. My issue is when using the highest sample rate my DAC can handle, 352.8 / 384, I get popping noises every 30 seconds or so, very much like the subtle popping when playing vinyl. If I switch to 176.4 / 192, I no longer have the popping noise. See screen shots for CPU and RAM usage. Link to comment
stefano_mbp Posted October 12, 2022 Share Posted October 12, 2022 @Badge I have had a similar issue with my SOtM sMS200 Neo (not ultra) that I solved setting (in HQP Output device settings) the buffer time to 10 Stefano My audio system Link to comment
Badge Posted October 12, 2022 Share Posted October 12, 2022 Stefano, thanks for the tip. I had increased the buffer time, see HQP settings screenshot. Link to comment

If not, we know it's not the problem. My M1 mini can do 1.5Mhz pcm all day long every day so 352.8Khz should not be a problem. No electron left behind. Link to comment

Also, keep the cable between the ER and the NAA as short as possible and use a CAT 6 with no grounding (plastic ends). Blue Jeans Cables are reasonable and good quality. Also, power it with a Linear power supply if possible and use a good quality cable for that as well (Ghent makes reasonable quality DC cables). Lastly, don't put any other devices on the ER.

Or, if you're going to get one cable from Ghent, you might look at getting both. I personally (purely subjectively) liked Ghent's very reasonably priced JSSG360 Ethernet cable much better than the Blue Jeans in my system.

Thank you for the info - I am guessing that you have some experience with it. A couple of questions - 1. The manual says that the supplied PS is all that you need. 2. Metal-ended Cat 6A cables are fine, so long as there is only one connected on the "B" side. Your comments would be appreciated. Link to comment

Your comments would be appreciated. Yes, the included PS should work fine. You might get a boost in performance with a LPS but start with the included PS. Also, Ethernet cables with metal ends can be fine if the ground wire is only connected at one end. I have many Audioquest cables that are built this way. They are Cat 7 or Cat 8. The Cat 6 spec calls for no end to end ground connection thus the use of plastic ends. As to whether it will improve your system, only you can make that decision after you test it. Link to comment
Schafheide Posted October 16, 2022 Share Posted October 16, 2022 Given that I already have the Cat6A (metal end) cables installed, I wonder if it is possible to find an RJ45 Cat 6A coupler (which is insulated), then a short length of Cat 6A (metal end) cable. Or else a coupler which is not insulated, and then use a short length of Blue Jeans (plastic end) Cat 6A cable. Link to comment

Why not just get a new ethernet cable with the plastic ends on it? Account Closed 1 No electron left behind. Link to comment

Before looking for such, do a simple multi meter test to see if the cable you have has the ground connected at both ends. If it does just buy a Ghent or Blue Jeans cable with plastic ends. Neither one is expensive. A coupler would cause some signal loss and possibly defeat what you are trying to do with the ER. You can then A-B test the two. Don’t overthink this. Link to comment
Schafheide Posted October 16, 2022 Share Posted October 16, 2022 Of course you are both correct, but, unfortunately, the cables (which do have the ground connected at both ends) are inside the walls plus both Ghents & Blue Jeans are very expensive here in Oz. So I am looking for a cheap work-around. Maybe wrap Polyimide Hi-Temp Tape around one metal end - I have done this on the USB cable into my SU-6. A pity that the socket in the EtherRegen is not insulated, thus eliminating the need for plastic end cable. Link to comment

I don't think there is any adapter like the one you want but Google is your friend if you must go that route. Link to comment

It is a fairly easy DIY project or any tech could do it. Link to comment

A pity that the socket in the EtherRegen is not insulated, thus eliminating the need for plastic end cable. If you have wall sockets that have grounds connected, just use CAT6(a) U/UTP patch cable for connections. Even switches with seemingly plastic connectors can have small metal taps on the connector sides for ground connection when using STP cables. IIRC, Apple's Airport Extreme was one of such. If necessary, there are some plastic female-female RJ45 connector blocks that can be used.
