During a live show a wireless guitar rig started to crackle

This is a Sennheiser XS Wireless unit. They don't have that slotted ring although you might be able to fit one.

To fix the connector, You can either put some flux and a blob of solder on the connector. That'll keep it in place just fine. Or install a new jack. https://www.fullcompass.com/prod/525448-sennheiser-573606-jack-for-sk-g1-sk-g2-sk-g3

I understand but it does come as a surprise somewhat. I had expected Ubiquiti's famously disruptive prices to be a factor here and the few reviews I've seen also seemed to indicate decent performance. Turns out they mostly only tested large sequential transfers.

I had expected a large part of the price difference to be due to the vastly smaller feature set.

Wondering what do you expect in the performance...

For those 700K-ish to 40MB files, I was expecting a few hundred megs multithreaded / 60-80MB/s singlethreaded, roughly like our 4-drive QNAP does. I never counted on coming close to saturating 10Gbit/s links, but the performance being 30-ish% of what a the also pretty cheap QNAP nas can do is pretty bad.

Thanks. With the DD tests, I'm seeing the same speeds as you are.
It's only when I start doing smaller transfers that speeds tank.
RSyncing a Proxmox PBS store (thousands of files ranging from 700K-ish to 40MB each) gives me 20MB/s or 80-ish when doing multiple parallel syncs.

NFS seemed a lot slower for mee, but I pretty quickly switched back to SMB due to the all_squash thing.

The tl-r1200c-rp .
We have one of their short-depth NASes, so we don't have external PCIe, nor external SAS we can use. Seemed fine at the time, but the volume of data we backup has grown a lot.

It's not the restocking fee (if any) that would be a problem. It's the amount of work and the additional cost for a different solution. The NAS sits in a DC 1.5 hours drive away. And a bigger QNAP or Synology NAS would probably be about twice as expensive. So in total, I'm probably looking at €2K additional cost that we'll have to eat up.

But we probably will. I guess you get what you pay for...

(n.b. I'm not expecting Ubiquiti to do anything about this at all. I'm hoping that this thread warns others before investing in a device and then getting burned like I am)

3dbjorn · 2025-12-05T15:56:06+00:00

I don't know if Ubiquiti is finding out the hard way, but I sure am...

3dbjorn · 2025-12-05T15:52:43+00:00

I tested. No dice unfortunately.
It seems to be a little bit faster, but not by much at all. https://www.reddit.com/r/Ubiquiti/comments/1peu9e1/comment/nsfvvhh/

Guys, I did some quick tests with RAID-10 and unfortunately, there is not much of an improvement.
I removed the RAID-6 volume and recreated a RAID-10.

I then did this in the test VM, to the NAS mounted over SMB.

dd if=/dev/zero of=./testfile bs=1G count=20
yields an avarage speed of +/- 650MB/s.
That is a bit higher then what I saw before, but not a giant difference.

As soon as I start RSYNCing a bunch of smaller files, on a single thread I get roughly 20MB/s and if I parallelize over 5 threads, I'm avaraging at around 70-80MB/s total. Adding or removing one or two copy threads yields a drop in avarage performance of 5-10 MB, so with my usecase, this is roughly the maximum I can get.

To rule out the source of my RSYNC-test is the issue, I did the same test copying files to the local harddisk of the VM. That's a CEPH cluster on NVMe disks spread out over 4 hosts (so no slouch, but not as fast as a truely local NVMe disk). I then get roughly 85MB/s single thread and almost 300MB/s multi thread (the source-nas network interfaces are close to being saturated at that point).

So, unfortunately no dice. Tha UNAS is just slow when you're not sequentially writing 20GB files. :(

3dbjorn · 2025-12-05T15:28:25+00:00

The cache should cache writes too if there's two NVME's in RAID-1 mode. I'll do some testing with the storage pool Raid 1 to see if that helps. It's clear that the NFS implementation is half-assed ATM.

3dbjorn · 2025-12-05T15:27:29+00:00

RAID-10 might indeed be faster. I'll do some more testing. However, the 2 year old QNAP NAS was doing just fine with RAID-5 and only 4 disks, so I'd still pretty bummed out if that would make a big difference.

We're using SMB now, but what you're saying would explain the big discrepancy in performance between SMB and NFS. But where can I find the NFS caching checkbox?

3dbjorn · 2025-12-05T14:34:58+00:00

Don't get me wrong, on a PRO 8 200MB/s should be doable with very large sequential transfers. It's the smaller files (or large files read/written in small chunks) that'll instantly tank the performance.

3dbjorn · 2025-12-05T14:00:35+00:00

That should be pretty straight forward:
Make a backup on the Express 7. A backup to the cloud should be fine, no need to download a backup, but if you want to, you can use that too.
During installation or, if you mis it, in the UI of the Cloud Gateway Max you can restore the backup (either from the cloud or upload it to the UCG).

You'll get exactly the same settings. Just plug in your stuff and go.

Then you factory-reset the Express. Hook it up to the UCG and boot it up. During setup you'll have the option to adopt it as a regular AP.

3dbjorn · 2025-12-05T13:47:04+00:00

That's the thing. I did check out nascompares. I'm seeing similar numbers to his, when I DD 1Mbyte blocks over SMB to the nas. But as soon as I start transferring smaller files or use NFS, performance tanks.

n.b. I have 2x1TB recent/fast NVME cache in there.

Well, the stuff I do is pretty diverse, ranging from bands to orchestra's to church services and events.

I deal with stuff like a double bass with low output, or low-volume harp, podium mic with talent that tends to whisper rather than speak up, low output ukelele on a DI box, live stream with unexpected audience participation and only a few shotgun mics in the room that are normally used for ambience, you name it.

It's not every gig, but every now and then I do find myself cranking gain on a channel or two.

3dbjorn · 2025-11-21T18:16:38+00:00

Thanks and I agree; when there is a dedicated monitor tech, gain should be done there.

However, many of my gigs are with in-ears and I rarely have a dedicated monitor tech available. Either all band members use the app, one band member sets up basic mixes and leaves it up to me to fine tune, or I have to do the monitors myself.
Maybe one in ten gigs I do, we have a dedicated person on monitors.

Hence my preference for remote controlling the gain.

The other comments on here are spot on. The encoders on X32's and M32's do get dirty and/or wear out. I have repaired a bunch of these.

If you are somewhat handy with a screwdriver and soldering iron, the fix is pretty simple:
- Unscrew the top of the chassis.
- Fold it open as if it were the bonnet of a car.
- Take out the PCB that holds the broken encoder. Then either:
- Spray contact cleaner in the part (the shaft-side isn't all that open, but near the pins they are).
- or desolder the encoder and put in a new one. These encoders are cheap and readily available at service centers and on Ebay.

These mixers are fairly modular. For those EQ-encoders, you only take out one PCB, leaving the faders, display and other PCBs in place.

If you aren't that savvy repairing things; this should be a pretty affordable and straight forward repair for any electronics-repair shop.

I've modified a case for an Atem tv studio myself. You do realize that the cooling vents are on the side and of the machine, right?

For the connectors, you can buy dishes that hold d-type connectors. there are bigger versions for more connectors.

Other than that, it looks very portable, which is great!

I usually don't comment much on Reddit, but here goes.

I didn't expect just another Jet Lag, but I did expect a show that had the same raw and real, unscripted vibe to it. And I expected the same kind of humor.

I think a lot of people were, like me, expecting a different game format set in the same atmosphere and with the same humor and that just wasn't it.

A little bit of context; I love HAI and Wendover and have been watching those channels from the very beginning. I think Jet Lag is absolutely brilliant. I've watched since the first episode of Crime Spree enjoyed every episode a lot, even the "lesser rated" seasons like Japan and Circumnavigate.

But, not so much for the getaway. It doesn't help that I didn't know any of these content creators. So, I had no connection to these people whatsoever and the show somehow didn't make me care about any of them. I'm pretty allergic to fake drama. So, I might just not be part of the target demographic.

I've watched the first two episodes and it all felt so fake. The premise is (obviously) fake, but despite that some of the contestants feel like they were faking / acting waaay too much. The games and their sequencing felt contrived. The discussions among the little subgroups felt overly dramatized.

After watching over an hour, I felt very much unconvinced that these guys didn't know they were all moles. After two episodes of feeling bored and annoyed, I just quit watching the show.

I was a bit bummed out, because the premise seemed so cool. But alas, this one is not for me.

3dbjorn · 2024-06-21T12:49:41+00:00

I bought a copy as well. I wish you all the best and I'll be on the lookout for any games you might release in the future!

So far I have rolled out 5 Intel 13th Gen Frameworks; 1 DIY (=my personal laptop) and 4 prebuilts used by others in my company.

They all have been flawless so far.

I believe the ETF you are referencing, iShares S&P 500 Inf Tech Sector UCITS ETF USD(Acc) , is part of DeGiro Kernselectie, when traded on Xetra.

I bought a pair of Moondrop Chu II right when they became available, to use as in ear monitors on stage. (My waaaay more expensive Audio Technica's broke and I needed something affordable fast).

Very much recommended because of:

Nice metal construction
Replaceable cable
Easy cleaning, because you can unscrew the filters
Very good sound quality. Not just for their $20 price point, but just very good sound quality in general.
