Truly new visions and products can only emerge by leaving the beaten track. For audio/video products this is definitely not the most common and easy way. Revolutionary technology rarely comes from the marketing department either. For us at KE this is the result from our deep knowledge, thorough development and the strong ambition to develop unique products with an outstanding price/performance ratio.
The convincing proof that this approach can lead to some very remarkable products can be found in our SR PLUG and QA PLUG. Different and unusual for sure but by no means less effective. Just follow your eyes and ears. The improvement in sound and picture quality is impossible to miss.

KE this is the result from our deep knowledge, thorough development and the strong ambition to develop unique products with an outstanding price/performance ratio.
The convincing proof that this approach can lead to some very remarkable products can be found in our SR PLUG and QA PLUG. Different and unusual for sure but by no means less effective. Just follow your eyes and ears. The improvement in sound and picture quality is impossible to miss. We proudly present to you the SCHUMANN RESONANCE PLUG What is the Schumann Resonance?
In 1952, the German physicist Wilfried Otto Schumann discovered that the cavity between the earth and ionosphere acts as an electromagnetic resonant cavity. Energized by electrical discharges (lightning), very low frequency resonances are created around the earth.
The lowest frequency (the fundamental)has a frequency of only 7,83 Hz which corresponds with a wavelength of 38,000 km/24,000 miles (the circumference of the earth is about 40,000 km/25,000 miles). The ionosphere protects us against harmful radiation from the sun and from out of space, there are indications that the so-called Schumann Resonance plays a role in this. On the earth, mankind is creating more and more high frequency radiation. RFI (Radio Frequency Interference) and EMI (Electro Magnetic Interference) will pollute your A/V set and, according to certain people, also your listening room and your body.
What does it do?
The newly generated 7,83 Hz wave by the SCHUMANN RESONANCE PLUG will counteract the effects of this radiation. With the SR PLUG, you will notice a clearer sound with a richer timbre, more details, a deeper soundstage and a more powerful and dynamic sound. The SR PLUG relies on a fully different principle than all other mains related products. Thus, the SR PLUG cannot degrade the effect of other products. On the contrary, the positive effects do enhance each other.
Where to install?
For best results, we advise to position the wire antenna vertically in the middle between your loudspeakers. Most practical way to do so, is to attach the antenna to the wall behind them. The SR PLUG is sensitive to its orientation, you can estimate this by means of listening. Under most circumstances, the middle position of the level adjuster is the most pleasant one, but feel free to turn it up a little more, in which case you’ll hear more detail and precision. However, you may notice a slight decrease in timbre, but this will mainly depend on the set used, the listening room and your personal preferences.

“Kemp Elektroniks SR PLUG, A Follow-up”,
by Dennis Parham
“In conclusion, I am in total concurrence with CP’s review. I also agree with Mr. Kemps brochure that the SR Plugs “provide a richer more detailed and holographic sonic experience.”
Switching them out to conduct a quick A/B was very easy by simply unplugging them. Immediately,
upon doing this, I noticed a less dimensional stage with images stuck more to the physical plane of my loudspeakers.”

“Kemp Elektroniks Resonance Plug, Resonateswit h me...”, by Clement Perry
“The sonic benefits of adding the Kemp SRplug(s) into my listening space were immediate and obvious. With the RR-77 still powered up, I could easily hear greater three-dimensionality placing a single Kemp SR plug directly center, between my Sunny loudspeakers. Yes, all the accolades formerly applied to the RR-77s were applicable to the SR plug. A greater sense of air and bloom seemed to surround instruments. The acoustic space of each recording also made itself more apparent making the leap of faith of “being transported to the recording” that much more believable.”
Home Studio, mei 2008; “Even mysterieuze als muzikale accessoires”, door John van Polen
“The effects of the SR-plug are totally different from the ones of the QA-plug. The effect is more in the area of clarity, damping, purity, and the total suppression of noise. A cleaner, more analytical sound with more details, without a shrinking of the soundstage. After a few days of settling, the combined effects of both plugs have become even more noticeable. The sound has become more natural, it simply sounds more like real music.”

Responses from customers
Received the SR plug replacement yesterday and tried it last night. Must say that I’m happy with the results. :) Imparts a more controlled feel to the sound and allows one to be better drawn / relax into the music....
Mr. Kong Wy Mun from Singapore
When I plug the SR and placing the wire between my speakers, immediately everything become more cleaner with great hights making me to hear more from the recordings. Micro- details.
Wow! what a great tweak.
Khat from Japan
Being a gratified user of the Kemp QA-Plug and SNS-Plug for several years now, I was very curious about this new SR-Plug. It must be said: the effects are obvious at once. A more refined treble, better retrieval of detail (even new details appeared!) and a more “real” sound. At the start, I was too lazy to strech out the antenna, which was wrong, because this clearly enhances the effect. At my place, the SR-Plug sounded at its best when set at maximum output. This triggered the idea of buying another one, which raised the benefits as expected. In my opinion, this is the best Plug Kemp has ever made.

Yesterday, I collected a SR-Plug at my dealer’s to try it at home. I kept the device right away, because this Plug does exactly what is in the review by Mr. John van Polen. A lower noise floor, bass is more taut, more accurate imaging and better retrieval of detail are among its effects. In short, an astounding result.

“The music presentation is super clear, even more dynamic and soundstage depth and width presentation is so real. This is the most significant tweak in my 20 years into hifi. Simply breathtaking!”
Mervin from Singapore
I feel very happy with “my” sound: wide, deep, open, transparent, tidy, rich, dynamic. I can hardly imagine anything better downside a 5 figure high-end exotic monsters. At least - until this weekend.
*Step 1: turned potentiometer down to zero, plugged SR and here-wego. I’ve chosen Hail-the I Dub compilation: a heavenly production, clean, clear and tidy.
*Step 2: turn clockwise to 9 o’clock. Apart slightly deeper bass (illusion?) I did not notice audible differences.
*Step 3: potentiometer
turned to 11 o’clock. Wow! Bang! The bass got “edge”, the soundstage depth becomes deeper, higher, wider, naturally balanced with whole lotta “black space” between instruments. Almost holographic. Voices placed in front of drums (as it should be), colour and tidiness of voice to die for.
*Step 4: potentiometer turned from 1 o’clock
to max. Too much of a good thing equals nogood. *Back to 11 o’clock – back to heaven. The sound reminded me to the “deep listening” sessions after bong (ab)use when I was young(er).
*The last step: SR Plug switched of. The sound I’ve thought was fine. seemed - wall of sound!
Plugged again. I will never unplug it again.
I damn love it

A spectacular device, as far as I am concerned the most important accessory in my audio chain. Not the cheapest around, but the very best I know of. A recommendation well-deserved.
Walther Steenbrink from Apeldoorn/
the Netherlands (translated by John van Polen)
...I hooked it up last night. This thing is nothing short of amazing- it’s presence worked a great improvement in my system. The reviews of this device were right on the money: it may be the most cost-effective tweak I have ever used.
A customer of one of our US dealers;
First impressions of this device are positive: if fact, very positive but difficult to describe.
To sum up the very unusual effect would be to say that music played through my system sounds more “pleasant”. This is an ambiguous word but my wife confirmed this description.
She mentioned that listening with the SR plug is “less strenuous on the ears, easier on the head”
