CoolI went digital coax. No problems so far, aside from the refrigerator thing.
Might be a "feature" of the TV you didn't notice before. Some video devices and apps have dynamic audio processing. Have a poke at all the menus you can find, system set-up and within apps.I do have a weird, periodic, ever so slight drop of sound using HDMI eArc, and I can't figure that one out, as it is unrelated to the refrigerator issue. I've tried switching between PCM and Auto for digital output audio format, as well as switching HDMI eARC mode between off and auto...but same-same. It is not a huge inconvenience, but I am curious what is causing it. Maybe it's latency streaming through NOW. I haven't paid attention during YouTube or other services.
I am playing with the delay timer (between video and audio) to see if that does anything, otherwise, I've tried everything. More a slight nuisance than anything, but I am still curious what's causing it.Cool

Replace or fix the fridge. When you have no control over the leak in the roof then you are forced to use buckets. Otherwise fix it. From an engineering point of view, adding a UPS is adding considerable complexity to the audio system. Do you really want that?Me again, and I just simply don't know where to start with my research. I am looking for a small UPS to stop the (likely unnecessary) fear of the refrigerator compressor damaging my speakers. I say it's likely unnecessary because I don't believe the compressor turning on causes a surge. I think it draws down voltage from the speaker.
I'm learning slowly about UPS on my own, but I am no electrician and every electrician I have called wants to charge me money for advice.
I've narrowed it down to a few devices, but I can't really tell which I should consider.
Here they are:
- Some have actual outlets I can directly plug my KH 120 IIs directly into with their supplied leads, which makes things easy
- Others will likely require some sort of IEC320 C14 adapter, or a power bar that plugs into an IEC320 C14 connection.
- Some of them give me a dB specification for their noise, others don't.
Gah...I am so out of my element here, and looking for advice before I make a purchase I will regret, even if it is only about €120 I will be spending. I'll keep reading online in the meanwhile, and hoping the occasional voltage drop doesn't hurt my babies.
- V7 UPS 750VA Desktop UK, 750 VA, 450 W, Sine, 632 J, 6 ms, 10 ms
- Kohler 600-800VA, Single-Phase, Standalone
- APC Back-UPS BE850G2 - 850 VA, 520 Watts, 8 Output Connectors
- Kohler 600-1600VA, Single-Phase, Standalone, Transformerless
- V7 UPS 600VA Desktop UPS with 6 Outlets, Touch LCD (UPS1P600E), 600 VA, 360 W, Sine, 180 V, 240 V, 50/60 Hz
Maybe all I need to do is buy a new mini refrigerator - that sounds like an unlikely solution because eventually I am sure the compressor on that will draw down power as well.
All I want is peace in my life. I've come so far, damnit.
Considerable complexity? They are just plug and play. I believe the OP was going the cheaper route as it fixes his problem and he can let the fridge go until it dies in many years.Replace or fix the fridge.

That's the user point of view. I said engineering, from which POV adding a UPS is a bodge. The electric supply should not be that bad and iiuc the issues causing the supply instability are all inside OP's property.Considerable complexity? They are just plug and play.
Iirc, OP described it as a mini fridge. Fixing or replacing that may not be less expensive or much different.I believe the OP was going the cheaper route as it fixes his problem and he can let the fridge go until it dies in many years.
If you find a good one we can meet there Monday for a jar.and see if a surge-protected power bar
I had no problems so far, but now I bought a new microphone and had a 50hz hum. When touching the audio interface it got better. When touching the microphone it got worse.Have a look here:

There are other alternatives so as not to spend 84E for a pair of XLR/RCA cables, you understand very well) Yep,there are lots to choose but at honest buys you get what you pay for. I have plenty cheap 4-5 euro RCA plugs who once was gold and now are turning to silver :facepalm: (and that's...www.audiosciencereview.com

RCA to XLR Cable ("pseudo-balanced") to buy ?
Also note that in the schematic at the end of the above paper Putzeys is making use of the full XLR connector,ie apart from the usual -+G also connects ground with the XLR's case (through the 4th pin on top usually) on both input and output connectors. (TRS usually does that naturally,by it's...www.audiosciencereview.com
Still like them?
(I would at least thoroughly test them,both how they are wired and with the DMM both end-to-end AND at each end,open )
Edit:They also use the neutrik-rean brand mostly.Rean is made in China (but it's Neutrik's company and under their QC I hope,so no harm to it)
Sort out the power supply or the fridge.A few months in, and everything is still sublime--I'm very proud of the choices I've made and thankful to everybody's help here...as a refresh, here's my gear:
A few notes...
- Technics SL-1210GR with a Nagaoka MP-200 moving magnet cartridge
- WiiM Ultra
- Neumann KH-120 II active monitors, connected via optical coax cable
- I'm learning to deal with the occasional sound drop caused by a voltage suck from my fridge, largely because I would rather buy more records than a new fridge, and I don't know enough about UPS to warrant the expense, nor do I have the time and energy to go deep on research about them (I can't even figure out how I would plug my Neumann monitors into one - the outlets look like the ones that cords from electronics plug into with a lead on the other end...so where do I plug the leads from my speakers into it?...this sounds so dumb)
- I've bought ~€1K in vinyl so far, and it fills me with such joy to buy physical versions of albums on heavy rotation in my digital world (Spotify Premium). My listening activities are probably an even 50/50 right now between analog and digital, and when I do digital, it's usually for more recent/modern/previously unheard music (hip-hop, EDM, metal, etc.) or to scout records that catch my eye in the record shop or for future purchase.
- I'm now contemplating upgrades...it IS Christmas, and I have been a good boy. A sub is a non-starter due to restricted space, so I think the next most logical steps are
- an external phono stage,
- power conditioning, even though I am not sure which components need it, or what makes a good one,
- another cartridge...maybe a moving coil (which would require an external phono stage as the WiiM Ultra only handles MM I believe)
So, I am tapping into the hive mind of ASR. What are your recommendations? I've only just started my reviews of ASR reviews and I still get overwhelmed with the technical terminology used so I usually glance at SINAD, and then scroll to Amir's summary at the bottom.
I would add a +1 for getting a UPS or something to prevent possible electrical problems from the fridge. Something like this should do the job.A few months in, and everything is still sublime--I'm very proud of the choices I've made and thankful to everybody's help here...as a refresh, here's my gear:
