Hoping to get a demo of the grid and EMI next week. If I do, will report back. Nervous at the price..... !
The Grid Protector and the EMI Protector By Scherzinger-In My System and I’m Blown Away
- Thread starter steve williams
- Start date
Cost? Can’t find in EU a website showing the price in euros. I’ve sent an email to sales dept of Schnerzinger, still waiting an answer.
I suggest reaching out to Gideon here at WBF via PM. His username here is audioarts
My advicee to interested users would be to arrange a demo unit from your dealer. My guess would be they wont be returned
Schnerzinger seems to rightly feel that this product line is a must have for any serious audiophile system and is going all in as I also understand they also have new cables and fuses

Still hard to grasp what is does and how it works, or should be used, cleaning up power line noise via an antenna? Wireless ?
Question is, does it matter? If you get a demo and hear a major difference, would you refuse to buy it because you dont understand it? This to me is the ASR mindset, and one I completely reject
Nevermind, I found the manual.

The GRID PROTECTOR can also affect the HiFi system very effectively in other places in the house. Used e.g. in the kitchen or at the workplace in the same circuit of the
electrical devices there, it can also have a positive influence on the current phase and protective conductor interferences. This effect can extend into the HiFi room. Conclusion: just give it a try.
The procedure for setting the switches as described above is a recommendation and in most cases the most effective variant.
All variants of switch positions in all combinations are allowed, the device is not damaged when trying all possibilities.
If after a while you once want to hear the performance of your system without your GRID PROTECTOR, the buffering effect absolutely has to be considered. If the GRID PROTECTOR is switched off for a short time only, it still takes effect because of the buffering of the power supply unit.
Detach the power cable of the GRID PROTECTOR for the power grid (if connected also the 12V power supply). Remove the antenna, place the unit on the floor (best stored
on the side) and set the middle switch POWER to position 0. Keep these conditions for several hours, preferably overnight. This way you achieve that the GRID PROTECTOR has no effect any more.
Upon recommissioning the interfering fields will be cleared again fast.
To maintain its performance, the GRID PROTECTOR it should be connected to the grid with the 12V power supply once a year for approx. 15 minutes»

this is very interesting . I have all switches in the ll position on both the Grid and EMI protectors
Thank you for that. Talking to Gideon he recommended all in the ll position for my ALL tube system. It does seem best TBH. I also use the wall warts in both devices. So all set to ll and wall warts employed in both
OK and the short answer for me in my system in my house is..... nope. Nothing. 3 different switch positions for 3 sets of switches made no difference. With or without power. Couldnt tell if it was there or not. Maybe a very slight softening/smoothing on the top end, but again I would fail a blind AB test. Maybe thats good news in that my setup doesnt suffer from EMI noise..... But I just saved myself $12k
Reports from the field, echoing my own observations, is that the II position addresses tube based systems more effectively whereas I position benefits ss components, but trial and error is key to really lock in. Schnerzinger addresses varied system and component combinations by allowing the end user to fine tune via the switches, but once the sweet spot is discovered, you’re done.
At least one very close friend of mine has been contacted about these products. Two very close friends who potentially are interested in the products have asked me to look into them.
I am very much looking forward to hearing an A/B demonstration of them at Steve's house on November 2. Until then it would be great if someone could answer these "yes" or "no" questions, which follow up on Marty's third question in Post #26* supra:
1) Does the device operate as a wideband RF receiver which detects EMI/RFI at one or more frequencies?
2) Does the device identify the EMI/RFI frequency of greatest perceived signal strength?
3) Does the device act upon the EMI/RFI frequency of greatest perceived signal strength by transmitting a countervailing or canceling signal at the same or at approximately the same frequency?
* I did not see that Marty's questions ever were answered.

They weren’t answeredfor a reason
The Grid Protector and the EMI Protector By Scherzinger-In My System and I’m Blown Away
How much are these? Hard to see any guide regarding price anywhere.

I doubt you’ll get answers as I’ve said before that it is proprietary I don’t have the answers either as I’ve asked myself.
What I find very interesting is that from the manuals they function with or without the AC attached. although IME they function best plugged in and I’m only speaking now for my system Further the best A-B is to pull the plugs, take down the antennas and wait 24 hours for the buffer effect to dissipate. In the A-B I did yesterday when Jerry was here was to merely turn off all 3 switches in each protector. I didn’t even pull the plugs. What I heard by doing that was a much flatter sound lacking some of the gusto that had been gained when both devices were on
Once again I will say the best A-B is in one’s own system.
Thank you. Then it cannot be a wideband RF transceiver.
Always!
I'm not surprised that my queries weren't answered. If anyone knows precisely how these devices are thought to work, why would that information be disclosed? As already suggested, it would surely be proprietary information. Furthermore, who cares what's in the box? The question is whether the results are pleasing. Some commercial success suggests it might very well be in a number of systems.
My limited understanding is that it somehow emits an out of phase signal or neutralizing signal to the EMI/RFI? that it is designed to cancel. (That would make it a transceiver for which the data is not clear that it is. Personally, I'm surprised that it can do anything without AC power, but WFT do I know?) But let's ignore the accuracy of those statement for now. As we said, if it works, who cares how it does?
My question pertains to the likelihood that EMI and RFI tends to be greatest in urban environments. If one is in a rural environment that has low EMI/RFI (I have tired to measure these in my room and can't measure any with good meters), would these devices still be effective? I guess the only way to know is to try it. But I need more to go on, such as measurable noise, in order to make that leap. However, I'd appreciate as many thoughts as possible from others who have tried these devices. It's intriguing stuff. I'd like to know more.

With my system being all tubes I’m betting my noticeable improvement might be better than those who are all SS. But honestly I could care less how they work. It’s what they do. They add nothing. It’s what they remove that is mesmerizing. I’ll leave the science to the scientists to ponder. To me it’s all about the listening and a simple A-B test in your system. To truly understand yiu need to have them unplugged and let the buffering dissipate to really get it. There are noticeable changes by turning off the switches but that’s only a small part of it. The manual suggests out of your system until the next day. That’s why I suggest having them for a while in your system to truly understand
Interesting questions.
I’m going to schedule a trial at home with the local importer (a very kind and passionate guy).
In any case, it's worth understanding more about how it works IMO, mainly for health reasons. I mean, if it only works as a receiver via the antenna (instead of transmitting as well) I'm less worried about the possible effects on the environment I live in.
