If you have 1 circuit in a room and it goes from box to box on the wall around the room, that is where you get ground issues.
The Grid Protector, the EMI Protector and The Allocator By Schnerzinger-In My System and I’m Blown Away

From what I recall this is actually advised. I know for certain that all my circuits are in phase as they were all tested when I built the room
As a result I merely plug the wall wart into the socket in the same direction as where the grounding pin would be if there was one on the Schneringer . They are in fact designed and built special for Schnerzinger
Yes but the ideal recommendation is to connect the PSU out of phase:
“It should be connected to a power circuit separate from the HiFi system – ideally even to a different power phase.”
Perhaps you should test with the AC plug flipped for the SMPSs.
I did. It sounds better the way I have it set. I did have the GRID in the other direction. Turned it several weeks ago. Sounds better now. Not sure how meaningful this is as I have all dedicated lines in my room
I am wondering where I thought I read that the power supplies should be in same phase because that is why I checked several weeks ago and flipped the Grid PS
In the Grid manual I see nothing re the power supply phase. In the EMI manual I’m only seeing this
*
Note the correct phase
of the 12V power
supply when
connecting to the
power grid (marked
with a silver dot on the
plug of the device).
Measure the phase of
the socket accordingly.
I took that to assume phase should be correct. You have better search skills than I

Note that for the MULTI-GRID the manual recommends connecting to the same AC circuit as the audio components. And same phase.
It doesn’t say not to, as for (some) of the other devices.
They do recommend that the PSU of the GRID be connected to a different phase and different circuit. But the GRID’s “input” or output should be connected to the same audio circuit AC. A bit confusing!
As Gideon says, it doesn’t really matter. I’m just starting with the manual, as that’s all I can do for the moment.

Im tending to agree with Gideon because so far my take on position 0,l and ll is "good, better and best". Set it and forget it. In my system I m not convinced I can hear that much if indeed there is a difference with the wall units of the PSU plugged into the AC outlets, in phase or out of phase and I dont know whether it is because I am using all dedicated lines in my room
I couldn't't find this in the grid manual In fact I could not find anything in the grid manual re the 12v SMPS except to plug it in
I’m looking at the 2022-09-V1 manual, which I downloaded from the website.
Step 1 describes connecting the Power connection to the first slot of the power distributor.
Step 5 describes the PSU recommendation to connect to a different phase and different circuit.
It makes sense because the GRID Power connection is meant to clean the incoming AC to the audio components, so it gets connected to the components’ power strip, The Allocator, in your case.
They want the PSU for the GRID in a separate circuit (ideally), which must be to minimize noise from entering the main AC line.
If I’m reading between the lines correctly, I think they recommend using it it Power mode 0, ie, without the PSU connected.
Note how they say to ‘operate initially in Power Mode 0,’ and ‘usually the setting is now complete’.

I read that too. Im not so sure Im going to put my trust in that rudimentary manual. As Luca and I say ...use the SMPS and all in position ll
Yes, you are right for the Multi Guards cylinder plug ins, but we are talking about the SMPS that feeds the Master.
Here from the owner manual:
5. MULTI GUARD MASTER– fine tuning
If the basic setting is not sufficient for the present interference field spectrum, two
additional power levels can be activated (switch position I and II). This requires the
permanent connection of the 12 V power supply. It should be connected to a power
circuit separate from the HiFi system - ideally even to a different power phase.
When connecting to the grid note the correct phase (marked by a silver dot on the
plug).Measure the phase of the socket according
On the other hand, if we are talking about the SMPS feeding the GRID Protector here what the owner manual recommends:
5. Increase in performance (switch POWER)
Usually the setting is now complete.
But if the base setting is not sufficient for the present interference field spectrum, the
permanent connection of the 12V power supply to the grid is required.
It should be connected to a power circuit separate from the HiFi system – ideally even
to a different power phase.

here's where theoretically I should have a problem as I have all dedicated lines the only way as I see it to make the grid work is to plug it into not the Allocator but the other open socket beside where the Allocator is plugged and to use the SMPS plugged into the next AC outlet that's open now on that wall. I still feel there might in fact be an optimal position but right now my GRID and EMI are behind my amps and by the front wall elevated on those great stands that vinyl Mike found
Why can’t you plug the GRID into the Allocator’s first outlet?
The MULTI-GUARD PHASE could go into the last outlet of the Allocator.
When ordering the MULTI-GUARD, did you get the 4 pack? If so, which of the types did you select two of? There are three types: PHASE/EARTH/ROOM.
This short review from a German dealer says that it works by producing the opposite signal from the noise:
...a few weeks ago, I was "trapped" on a ship bouncing around equatorial waters with a fellow passenger who was a retired CISCO engineer with patents adjacent to this tech.
Since his only escape was overboard in rough seas, I was able to pick his brain about these products, as satellite wifi let me follow this thread from afar (howze that for dedication?).
He surmised counter-veiling wave output to neutralize what the gear was producing. He thought the multiple switches likely allowed tuning for intensity and frequency, since you could approximately predict the operating frequencies with a range, but individual gear and/or placement might require "tuning" to optimize the effect to a desirable outcome.
He also said: "You audio guys are all crazy." But that may have been the rum talking.

all of my outlets on the Allocator are in use.
I got a 5 pack which as I understand ( as I have not received them yet) has PHASE x3, Earth, Grid
