Noise Eater



  • Parallel filter which doesn't slow down currents

  • Multiple filter stages

  • Small investment for performance

  • Protection against spikes between phase and neutral

  • Many disturbances in audio performance will disappear

  • More rest in quiet music parts and more details

  • Your soundstage will be more transparent

Review by

"An improvement that becomes audible as cleaner and quieter, freed from harsh sounds if they are not in the music."


What to expect?


The Noise Eater removes disturbances and noise from the mains supply. Because the mains current "passes-by" the filter it will not produce noticeable heat.
The sound character of your system will certainly not change, but the calmness in the sound and the stability of the image will be very noticeable, especially during working hours when there are more disturbance on the mains supply.
The Noise Eater is a small investment with maximum performance. The difference is audible immediately!

Where to use?


Like the Pulse Protector, the Noise Eater also has to be placed close to the audio equipment, preferably in the same (double) wall socket feeding the power strip, else in the power strip itself feeding your audio equipment.


The Noise Eater can be used for devices as CD-players, D/A-converters, tuners, phono stages, but also (integrated) amplifiers will benefit, even large ones! Several Noise Eaters in one (wall) socket is in most cases useless, multiple Noise Eaters throughout your house is a good idea, but feel free to do experiments…


The Noise Eater is not critical to phase, you can just plug the Noise Eater in the wall socket or power strip.

Working principle


Interferences mostly arise on the power network when switching a device on or off, but the disturbances can also be induced by industry in the neighbourhood or elevators in the building. Also computers, refrigerators, washing machines, dryers, switching power supplies, power drills and many other to the mains supply connected appliances can cause interferences.


Low distortion on your mains supply is hard to detect, you need assistance of special measurement equipment. The effect of the distortion however is very audible. You need a special filter to clean your mains supply without slowing down currents.


The Noise Eater is a parallel filter, this means that the mains supply current which feeds your audio equipment will not flow through the components of the filter. In fact the filter is only 'monitoring' the mains supply and then traps the distortion signals. Currents will not slow down and the distortion will be gone!



The circuit has multiple filter stages that have been extensively tested, to ensure the sound character of the music remains intact.

The Noise Eater also has an overvoltage protection between phase and neutral that converts each pulse above 250 Volt into thermal energy. The circuit itself has been poured into resin to prevent it from vibrating. Even the shell of the Noise Eater is a solid piece of POM-C material brought into shape by a CNC machine and lathe.

The Noise Eater IS not just a great filter….. it also has the LOOKS of a great filter!

Checking out the phase of your mains supply and protection against pulses are also beneficial for your audio system. These benefits can be achieved with our Sound Saver and our Pulse Protector.
