Acoustic Revive RR-77, 777, 888 Schumann Generator

mahgister, when you say "interconnected" I think all you mean is they are connected to the same power source, right? What I mean is they are all working independently, not synchronized, right?

With more listening, the effect of these things really is amazing. There's a sense of realism that is in some ways very similar to a lot of other things. Some of which I am unfortunately not yet free to tell anyone about. In terms of what I can though these Schumann cards are similar to HFT or ECT, but more liquid like Green Dream PHT, yet more palpably 3D than any of them.

As for how it works, its EM not acoustic. By all normal understanding the last thing you would want to do is add some EMI or RFI, which these do both. The EM is the intended low frequency Schumann wave. But each board also has IC chips so there's the inevitable EMI and RFI from that. All of which on paper is no good. Yet it sounds better. A lot better. No doubt about it.  

Incidentally, the great majority of what's out there talks about this as if its one precise frequency. Which it most certainly is not. Realize what we are talking about here is a resonance created by the dimensions of the Earth, its atmosphere and magnetic fields. Essentially what happens is electric discharges from things like lightning are trapped travel around this layer, going round and round as they dissipate over time. Its exactly like hitting a bell causing it to ring. Well, the bell has a fundamental resonance but it also has a lot of overtones, harmonics, a whole series of frequencies at which it oscillates.  

The same is true here and what makes it especially fascinating is when you look at brain wave patterns they all fall within the same range as these Schumann resonances.

There are even research papers documenting improved blood pressure and other benefits, in line with a big selling point being improved sleep, etc. (Put one by the bed at night, why not? Jury's still out on that one.) 

This is to address the point that it improves sound by improving mood, or something to that effect. In that case then it should improve hearing of all sounds. Well, the sound is really only different with music. I don't notice any difference in sound in my bedroom, or in my listening room, other than when playing music.

Therefore it seems to me the effect is on the electronics. The system electronics. This actually is in agreement with Ted saying it works better with his UEF technology. Which just because its good marketing doesn't mean it can't also be true.

Would be real interesting to compare this with FEQ. I suspect what Ted has done is take the basic tech and tweak to get more out of it. Whatever "it" may be!



 

Listen with your ears and experiment.... The sound waves will not know the price you have paid for your materials and devices controls and will act nevermind the price in a positive way or not...

That’s for sure. Professionally made often times does work a lot better. But also a lot of times its surprising how much improvement there is to be had from really cheap alternatives. Springs, just plain old ordinary springs, are surprisingly effective. Townshend Pods are so much better they’re in another league. But so is the price. You get what you pay for. Which is not always true. But that’s another subject for another day.

So the cheap circuit boards came last night. About the size of a pack of cigarettes, only half as thick, they sure don’t look like much. Took a couple boards from the shop, used a rubber band to hold them on there, plugged one in. Blue lights. No sound. Zero. Just the blue lights. Leaned them up against the side walls about a foot behind me and pointing straight out into the room. Unplugged.

Played some music. Plugged one in. Right away noticed a smoother more natural sound. Hmmm.... unplugged, brittle hard edge. Funny, never noticed that before. Sounded pretty good before. Now sounds kinda flat. Plugged it back in. Sure enough, way better, more depth too. Crazy!

Plugged the second one in. Wow. The front of the presentation has moved forward to where it seems in front of the speakers. Not the whole stage. Just the front. The back extends even deeper than before. Forward can be bad, like aggressive in your face. This isn't aggressive at all. More like closer than forward.

Everyone who hears my system winds up complimenting the imaging. Its even better with the Schumann generators. Especially the sense of space, the size and acoustic space of the venue is a lot easier to hear. There’s a smooth natural sense of ease, which was already quite good but now is even better. If I start to think something is missing, unplugging proves yes indeed something is missing- an overlay of gritty tizzy glare that might once have been mistaken for detail or extension but now turns out to have been noise. Like a whole layer of white noise has been removed. Something like that.

mahgister, you are running 9? This is only two. I’m ordering more!

Got notified two delivered just now. Fast shipper, and almost a week earlier than expected. Will have to wait for when I get home tonight.  

These are the cheap ones, just the circuit board no power, for $10 each. They do come with their own USB cable. Got a couple USB chargers to power them, just need to find a board or something in the shop to mount them on, mostly to make them easier to position.  

Wherever it is they should go. Of that I have no idea, other than people saying 5 feet off the floor. But the FEQ gizmo Synergistic sells sits low on the floor- although the more expensive Atmosphere models are pretty tall. It sure is interesting how closely his description of FEQ sounds like a Schumann generator! Also interesting the FEQ has a 5v input, which just happens to be the exact same 5v all the eBay circuit boards use. Hmmmm.....  

And I found a review of the Acoustic Revive unit with interior photos showing the exact same circuit board as I just bought for $10. All these boards are the same or very similar, as far as I can tell. There's another one from Nobsound, also the same board but with acrylic stuck on top and bottom, for $50. 

So far it seems the $10 circuit board becomes $50 with acrylic, $400 with a plastic case (and wall wart power supply!), and $1k to $3500 with one of Ted's fancy shiny brushed anodized metal spikey ground-plane iPad controllable tower thingamajigs. Can you feel the sarcasm? ;) I'm sure he figured out some cool way of timing the pulses, shifting the frequency or power, added a quantum flux capacitor or something to be worth all that money. I mean that. I kid, but that is one clever dude. Has he figured out the ultimate packaging marketing formula? Or is it something more? Or something else?? 

Who knows? But having spent more than a little time digging around trying to figure out what the hayek is a Schumann generator it sure is funny so many are the same darn board. T-minus 4 hours to find out what if anything I got for my ten bucks.

Thanks roxy54, that looks to be the same board as the rest and almost identical to the Nobsound unit with the acrylic covers. I just bought 2 of the cheap ones mahgister recommended for $10 (make offer, heh!) Real curious to see how they work.

Okay I will get 2 and see how it goes.
Thanks!

There’s a bunch of these on Amazon. They’re on basic printed circuit boards from as little as $13. Nobsound has the same PCB with a little acrylic lid for $50. The Acoustic Revive has the same PCB inside a much nicer looking but still cheap plastic case, $450. (Ted Denny takes the cake at more than twice that. But I'm sure his has a bigger power supply. It certainly looks the part.) It sure looks to me like these are all the exact same thing with the only difference being the power supplies. They all have a circuit, looks like it generates the frequency signal which then goes through a very long winding circuit trace that functions as a sort of rudimentary transmitter or transducer. Depending on whether its electrical or acoustic waves I guess. Some are round, some are square, they use batteries, wall warts, USB, but its all the same at the end of the day.

So what’s the deal with these things? I mean, besides they work. Too many reliable listeners saying they work to deny that. But what’s the deal? Can I really get the $13 board and go swimming in the all-enveloping sound stage?

What say you, resident expert mahgister? I’m buying and trying whatever you recommend. A link would be nice. Will this one do? https://www.ebay.com/itm/FM783-7-83HZ-Schumann-Wave-Ultra-low-Frequency-Pulse-Generator-Helping-Slee...
