Receiver shut off into 'protection mode' when I touched the metal door (static discharge from carpet) - Normal or potential electrical wiring issue?

[njweb]

Yes, that's the one.

Great, thanks.
Just checked the app's features out (surprised it has low rating).

If I am happy with the surround sound the way Audyssey on the AVR is set up, based on calibration I performed, then the app (Android in my case) functionality may not add any value for me?

I mean I watched a lot of scenes from the John Wick series again last night and also my new Roger Waters The Wall Atmos 4K disc and the sound was fantastic. Likewise I also watched a Hulu show and the surround and overall sound were great.
So I am not sure I would want to tweak it manually when everything is nicely balanced and dialed in.
Other than the sub volume level only, which I can do in 2 seconds on the subwoofer itself.

Just thinking it through now...

Absorb is actually not the best description, but that seems to have been often used in online articles. Imo, its more like "divert", or better still don't save words but call it what it is, such as...providing a low impedance path, like a short circuit....to ground (in the OP's case, that Belkin thing) so the voltage would drop very rapidly...

Agreed regarding 'absorb'. I was multi tasking when I typed it lol.
Thanks for the link!

PS: Yesterday, when I had to open the panel door to access the buttons for the protection history, I turned the power off first. Then I went up to the AVR and did my usual discharge routine before touching the metal panel door and it went well. I also carefully pushed the various buttons, without touching the metal panel door, to generate the protection history which I shared yesterday evening.
I then carefully closed the door.
Later I decided to run Audyssey again for my Atmos speakers and I used the same routine., but I left the door open for now (will leave it open for a few days).

But, even then, you can bet I was nervous before touching the metal panel door the first time (after what happened Friday lol)...
Luckily no issues at all.

You're right, but it's an easier way to explain it than "the MOV's resistance varies with voltage.....". It really bypasses the power supply hopefully, extremely quickly.

Compared with some people I have known, I'm a complete knuckle-dragger. My Acoustics professor had been recruited for the Manhatten Project and after he turned them down, they kept asking him to join. They didn't want to take "No' for an answer.

If the carpet was conductive, you wouldn't accumulate a static electrical charge- the whole reason it's called 'static' is because it doesn't go anywhere until you discharge it.

If you want to prevent this, you can do a few things-

1) buy a 1 Meg Ohm resistor and attach it to some part of the system that's grounded. If it means that you have to attach a wire to the screw on the wall plate for the outlet used for powering the system to provide the ground, do that. Touch the resistor's bare wire before touching any part of the system to discharge the electricity- it happens quickly, but you won't get a big shock and it will be far better for the equipment.

2) increase the humidity in your house.

There's nothing wrong with your electrical service- static electricity discharge means that whatever you touched is grounded. If you never get a shock, it means there's no path to ground.

PS: When I replied to you earlier, I had missed the first line of your reply (I was reading it while multi tasking the other day).
Yes, we're on the same page - In fact had written conducive (without a 't') to generating static electricity, as opposed to 'conductive'. I assume that was missed when you were replying to me...

That's what happens when I try to post something at 5:25 AM without enough coffee and by reading too fast. DOH!

Know the feeling all too well.
