SHUNT NOISE SUPPRESSOR PLUG
Noise Destroyer also known as Noise buster
The SNS PLUG is a unique product on the market. In a very simple and affordable way, a cleaner and thus better mains power is provided for your A/V set. All components benefits from this. The result is a clearly improved reproduction in all aspects.
Plug and Play, it can't be easier.
We are surrounded by electrical appliances more and more. Computers, peripheral equipment, wireless telephones, chargers, multiple TV sets, games consoles, microwave ovens, dishwashers etc. are common in most modern houses. All these appliances pollute the mains with noise and distortion. This pollution has a very strong - and highly underestimated - negative effect on the sound and picture quality of any audio/video system. The SNS PLUG is the most simple and effective way to reduce mains pollution. It has been one of our most successful products for years with thousands of satisfied customers.

There are two kinds of filtering, serial and parallel (shunt) filtering:
 |
 |
| serial filtering |
parallel filtering |
Serial filtering:
With serial filtering a coil is added in series with the consumer. The frequency of the mains will almost completely get through, because the impedance (alternating current resistance) of the coil is here relatively low. As the frequency rises (distortion spectra) the impedance of the coil will increase and as a result it will become less permeable for distortions.
A less positive property of serial filters is that there will always be a loss caused by the impedance of the coil - at 50 Hz - and the resistance of the coil wire. The KE-POWER SOURCE is a serial filter but because of its unique design, the disadvantage mentioned above is negligible.
Parallel filtering:
This is based on the principle that the parallel impedance will become lower when the frequency increases. The parallel filter will be ‘seen’ by mains distortion as a short-circuit, so it will be reflected to the source. Because the SNS PLUG is a parallel filter, the main current to your equipment doesn't flow through the filter, thus preventing loss of dynamics. Other advantages are the simple construction (low production costs) and a high flexibility. A disadvantage of parallel filtering is that it is less efficient than serial filtering.
The SNS PLUG can be plugged into any free power socket. Some effective places are:
1) As close as possible to the consumer unit (the source),
2) Into the distribution block (or line conditioner) of the A/V set
3) Next to the source of the distortion, e.g. light dimmer, fluorescent lightning, transformer (e.g. halogen light), refrigerator, computer, heating-installation, etc.
The KE-MND (Mains Noise Detector) is a tool to transform mains interference (EMI/RFI) into sound. Using this tool you are able to localize the source of the mains distortion. If you plug a SNS PLUG in the same outlet as your distortion source, you can judge the result.
For a maximum effect, we recommend to experiment with the placing of the SNS PLUG at various places. Multiple SNS PLUGS - placed on several spots in your house - is highly recommended.
The SNS PLUG has an overvoltage protection against peak- and induction charge. The stated current (88 mA) of the SNS PLUG is only capacitive. Your electricity meter will not even notice it. The real current consumption is 0,25 mA.
The SNS PLUG consists of 3 resistors, 7 capacitors, a coil and 3 varistors. This configuration is also used in the output stages of our POWER SOURCE. All parts are the best quality available. After testing, the entire circuitry is potted with a permanent resin to create an even quieter sound by preventing mechanical resonances.
The result of the SNS PLUG is a lower noise floor, higher definition, a wider & deeper soundstage, better resolution of lower frequencies and less treble harshness with more detail. The dynamic performance will be better too. You will hear the improvement immediately. Also, or especially, in combination with other line conditioners like our POWER SOURCE!
The SNS PLUG is available for the countries: Holland/Germany, Belgium/France, United Kingdom, United States/Canada and Australia.

The SNS MODULE contains the components of the SNS PLUG in a module type enclosure. Easy to install in a power amplifier, power strip, consumer unit or near any other source of distortion.
This is an example of a SNS MODULE installed in a Krell FPB700cx. The results are astonishing! The soundstage doesn't squeeze that much, which results in more details throughout the entire frequency range, a more natural and powerful bass and a more transparent midrange. A clear sign the designers from this amplifier (and from many others!) didn’t take mains supply as serious as they should. The simple fixed rubber power cord is a silent witness of this too…
