Hope you get every thing sorted!!
I had to make an executive decision and chuck out all the testable UPS's, about 150lbs worth of lead, so that thread is officially dead now.
I had some additional large unplanned unrelated bills pop up this week, and so now it is pushing the upgrades out to 2021 now.
The main level is all hardwood. They are currently replacing the entire floor, or at least replacing the damaged sections and re-staining the whole thing to match. To make matters worse, the floor has asbestos in it as well, so they have to zone it off in sections with plastic sheets and tape and wear special suits during the removal. Glad I ain't doing it! The original owner didn't disclose that there was any asbestos, had I known that I probably wouldn't have bought the place.
I still need air conditioning, a 4K laser projector and proper HT seating.
I'd like to re-do all the electrical in the HT, put in a second sub-panel which will be the solar-equipped one. Since I've already spent like $500 in solar already, that upgrade is happening! (240V split-phase and [email protected]
with 1kW RMS charging, for starters.) The new sub-panel will power all the lights, projector, and all the low-power rack equipment and charge an electric lawn mower. That should stop the lights from dimming on every bass note!
Then I just need to buy a Tesla and I'll be gasoline-free.
Some trim work and a few decorative panels etc and then HT v1.0 will be "complete".
Long-Term I'd like to sell my house and move to an underground bunker with twice the size of home-theater (v2.0), but I'm not sure how realistic that idea is.
The Motu system is pretty straight-forward, nothing too unusual.

(If you want a bigger system, more of these.)
and then you need a dedicated computer with TB or USB3.
It must be a dedicated PC, you can't do anything else on the box (bad things will likely happen if you do.)
For the DSP software I chose Adobe Audition, and Sandboxie Full (because Audition 2019 isn't multi-threaded).
I then manually assign each process to a dedicated core so that they don't step on each others feet.
All instances have all inputs and outputs available to them at all times as the Motu drivers are multi-tenant ASIO.
I found that 96khz to be the most stable, but you could drop it down to 48khz if you want/need to save some horsepower and AVB bandwidth.
I run an air-gapped and highly-modified version of Windows 10 Home, that has the best support for the gaming motherboard I bought and the Motu drivers. If you run Windows, NEVER connect it to the internet after activation, the automatic updates will give you nothing but problems.
If you are doing more than 32 channels then ideally the cpu would be a zillion core AMD Ryzen.
1-8 channels of DSP per core is ideal. If Audition were multi-threaded it wouldn't be such a pig.
I use an i7 8700 which is 6 cores, it gets pretty busy at 32-48 channels 96khz DSP. The MB I bought supports up to an i9 9900K if I need to throw 30% more horsepower at it. (~$400 upgrade.)
I have 16gb of ram in it, which is plenty. It's about 200-500mb per exe.
I put a 128GB 2500MB/s NVM M.2 drive in it, because it costs like peanuts. The computer boots in like 5 seconds.
If you turn off Audition auto-save feature, disk IO is zero. (I leave it on.)
The longest time I've ran the system is about 2 weeks 24/7/365 without a reboot. 100% stable, not even 1 dropped packet on any channel. YMMV.
Once you get it working, NEVER upgrade the OS or HW or FW or drivers.
If it works, don't fix it...
I highly recommend using optical HDMI and USB to eliminate all ground loops. You can get some pretty nasty groundloops going from XLR to USB to HDMI to CAT5 in giant metallic circles between the HT-PC, DSP-PC, LAN, SP, and the Motu rig.
In my case all 4 were connect to the same LAN, and the HT-PC and DSP-PC to the Motu via two USB cables, and HDMI from the SP to the HTPC, and XLR from the Motu to the SP.
The HDMI cable from the HT-PC to the SP was the main culprit, that one cable fixed the loop I had, but I ended up upgrading all of them to optical (because: why not.) Optical helps prevent noise and surge propagation and EMP as well. win-win
That alone was like $500 worth of cables though, so not for everyone.
But chances are if you are reading this to buy an expensive Motu-rig, a few hundred this way or that won't make much difference to do it properly. Just the 72-channels worth of Neutrik XLR Snakes was like $450 (and that's considered cheap.)
I literally have a half mile of unshielded copper in my room. If a sun flare or EMP occurs, my system is 9000% TOAST.
The foot-bone is connected to the chin-bone.
Even though I have a two SurgeX's and a UPS on the incoming power-line... it WON'T fix the-above problem.
I hate feeling helpless.
To solve this I need to do two things:
1) Surgically remove the AT fabric on all of my columns, and run all the wires through metal conduit (should have done that from the start anyways and I need to run more speaker wire regardless...)
2) Gut the drywall from my rack room, buy a dozen rolls of aluminium foil and shield all the surfaces to ground, and then buy a few tubes of green glue and some new drywall and put it back together. Maybe even add a quick layer of EMP-paint on the drywall just for extra-good measure.
Probably cost <$1000 to do all that. Given how expensive the equipment in this room is (like 6 figures), I'm not messing around. I think it is 100% do-able and worth-it. At this point I can't afford NOT to, even *if* it is improbable to ever occur. So consider it DONE!
Look: you'll all be turning into lake zombies etc, and i will STILL
be listening to tunes and cooking food on multi-kW solar until the very end. (I'll even be able to say "I told ya so!") hehe!
