Acoustic Revive RR-77 - Low Frequency Generator
ACOUSTIC REVIVE RR-77
Normally us Audiophiles and music lovers try products that attach to our hifi, be it cables or whatever, but Acoustic revive with their ultra low frequency pulse generator have come up with a completely novel idea.
The Acoustic Revive RR-77 ultra-low frequency pulse generator is small plastic stand-alone active device that plugs into a wall outlet there is no direct at all to your hifi system.
The Acoustic Revive RR-77 generates a 7.83Hz Schumann frequency pulse that 'shields' your HiFi electronics and listening room from radio frequency interference and thereby improves the S/N ratio so the electronics perform better, this results in a beautifully focused soundstage, the soundstage improves in quality with the Acoustic Revive RR-77 in place.
The Acoustic Revive R-77 ultra-low frequency pulse generator has "Wonderful effects of improving sound and picture quality!... The Acoustic Revive RR-77 is used in the recording and mastering studios of major record companies."
The Acoustic Revive RR-77 Schumann pulse generator is about the size of an outboard hard drive for a computer and plugs into a wall outlet. The Acoustic Revive RR-77 is nicely made and its light weight is due to a plastic chassis containing a single circuit board. The chassis is finished in an attractive silver or now Black finishes with contrasting gold lettering with the name Acoustic Revive. There is a power switch on the back and a blue LED illuminates to indicate when the Acoustic Revive RR-77 is on and working.
What is the Schumann Resonance the Acoustic Revive RR-77 recreates?
The fundamental frequency of the Schumann resonance is roughly the fundamental frequency of a spherical shell whose inside boundary is the surface of the Earth and whose outside boundary is the ionosphere, acting as a spherical shell electromagnetic wave guide cavity. The fundamental frequency ought to be roughly the time it takes electromagnetic radiation to go all the way around the spherical shell.
Since the speed of light is about 300,000 km/sec., and one cycle is the circumference
of the Earth, which is about 40,000 km/cycle,
the fundamental frequency should be on the order of:
_____________________= 7.5 cycle/sec
A cycle/sec is just a Hz, so that 7.5 cycle/sec is 7.5 Hz.
The Schumann Resonance's are actually observed by experiment to occur at several frequencies between 6 and 50 cycles per second; specifically 7.8, 14, 20, 26, 33, 39 and 45 Hertz, with a daily variation of about +/- 0.5 Hertz.
The 7.8 Hz observed fundamental resonance is close to the rough theoretical estimate of 7.5 Hz.
Acoustic Revive RR-77-How to use
The Acoustic Revive RR-77 is a very small light weight hard plastic box that you can put behind your speakers, but you can also place it in other posistions in your room, so it is best to experiment to gain to most satisfying results.
It comes supplied with its own power supply and short cord. It only measures 14 x 16 x 4 cm (W x D x H) and weighs 200 gr. The power consumption is 2 Watt and the generator runs on 12 Volt DC. It is a type of wave generater that puts into the room a subsonic frequency that either effects how you hear the system in the room or somehow effects the acoustic of the room it self.
The RR-77 is very easy to use, in fact it's just plug in a play, you don't feel anything, you won't even notice it's presence, but you will certainly notice its sonic effects on your listening experience. Eden Audio suggest you place the Acoustic Revive RR-77 at a height of approx 150CM for the unit to to be most effective, you can also experiment with positioning, but we've found at Eden Audio we get the best results by placing the RR-77 in between our main stereo speakers, but as usual experimenting is the key, have fun.
