Oyaide NRF 005T Tape 15mm x 4m

You may or may not remember a product from Stillpoints called ERS. This was a conductive fabric that was very powerful at reducing RF noise when placed very judiciously on cables and inside audio components. It worked great with digital gear, but was known to suck the life out of the music with analog signals and gear.

Oyaide NRF-005T is similar in it's noise reduction capabilities, but they have found a way to accomplish this without being magnetic, conductive or damaging to the audio signal.

NRF-005T solves the dilemma between noise reduction and original sound fidelity, providing a ground-breaking and innovative product for all audiophiles. They call the material PULSHUT®.

Conventional noise suppression materials have the property that the amount of noise suppression can be controlled by adjusting the magnetic material and the amount of magnetic material used. They have high magnetic loss characteristics and achieve their noise-absorbing effect by converting electromagnetic noise into heat. On the other hand, the impedance in certain frequency bands increases, which also affects the original sound waveform. This is similar to the properties of ferrite cores. This means that, as with EMC/EMI countermeasures, appropriate noise countermeasures were necessary for audio as well.

PULSHUT® is a highly functional non-woven fabric with a special surface treatment that provides high noise suppression performance despite its non-magnetic nature. This characteristic makes it possible to suppress only the noise component while minimizing the effect on the original sound waveform.

1. High performance non-woven fabrics that do not contain any magnetic material.
2. Effective against noise in a wide frequency range from MHz to GHz bands.
3. Substrate is as thin as 0.05 mm and extremely lightweight.
4. Excellent flexibility and can be attached to uneven surfaces.
5. Both the sheet surface and the cut surface have high insulation properties, so it can be attached to conductive surfaces.

Use

It is very easy to use. By attaching it to the input/output terminals of audio equipment, around noise-prone areas, and on cables and plugs, it exerts a highly effective noise suppression effect. It lowers the noise floor without deforming or distorting the waveform of the original sound, and improves delicate expression with fewer incidental sounds. In addition, the effect on video is to reduce blurring of contours and increase the clarity of colors. In sound quality, the S/N ratio is improved, the center of gravity is stabilized, the localized sound image is brought into focus, the sense of noise filling the air space is eliminated, and the sense of sound field is expanded.

Workability

Easily cut with scissors, etc., and has excellent flexibility, making it possible to affix to curved surfaces such as cables, etc. Excellent processability and workability.

The acrylic adhesive has reworkable adhesive strength, yet has sufficient holding power and can be reattached many times.

PET resin is used for the support, which keeps a stable shape even after cutting, and non-woven fabrics can be attached without fraying. The key to a beautiful finish is to apply a light tension while attaching.

A Few Warnings

1. Although the product can be used in a wide range of operating temperatures from -20 to 90°C, avoid attaching it to locations where overheating or cooling beyond this temperature is anticipated (CPU, GPU, vacuum tubes, etc.).
2. Avoid using the product in such a way as to obstruct heat dissipation, such as by blocking heat dissipation holes in amplifiers or PCs.
3. Avoid storing the product in direct sunlight.
4. Avoid storing or using the product in high temperature and humidity as much as possible, as the adhesive may deteriorate.
5. Wipe off any dust, oil, etc. on the adherend (mating surface) well before applying the adhesive.
6. Although reworkable adhesive is used, repeated application and removal will weaken the adhesive.
7. The adhesive is designed not to leave adhesive residue, but just to be safe, do not apply it to areas where adhesive residue is likely to be left.
8. Although the adhesive can be removed by hand after application, please do not apply it to areas where it may be difficult to peel off.
