OYAIDE NRF-005T Non-magnetic noise suppression tape

This is a noise suppression tape using PULSHUT (high-performance nonwoven fabric) developed by Asahi Kasei Corporation.
This is an innovative noise suppression material that does not use any magnetic materials, suppressing electromagnetic noise and radiation noise generated from AV equipment and cables, and reproducing sound closer to the original sound. The NRF-005T solves the dilemma of noise suppression and original sound fidelity, providing a breakthrough and innovative product for all audio files.

【Features】
● Parshat 5 features:
1. Highly functional non-woven fabric that does not contain any magnetic substances.
2. Effective against noise in a wide frequency band from MHz to GHz.
3. The base material is as thin as 0.05mm and extremely lightweight.
4. Has excellent flexibility and can be applied to uneven surfaces.
5. Both the sheet surface and cut surface have high insulation properties, so it can be attached to conductive surfaces.

● What is "PULSHUT"? :
Conventional noise suppression materials have the property that the amount of noise suppression can be controlled by adjusting the magnetic material and amount used. They have high magnetic loss characteristics and obtain a noise absorption effect by converting electromagnetic noise into heat. On the other hand, the impedance of specific frequency bands increases, which also affects the waveform of the original sound. This is similar to the properties of ferrite cores.
In the audio industry, it is known that magnetic materials induce ``generation of electromagnetic field = change in sound quality'', and noise countermeasures and original sound fidelity have been in an exclusive relationship. Similar to EMC/EMI countermeasures, audio also required appropriate noise countermeasures.
Pulshat is a high-performance nonwoven fabric with special surface treatment, and although it is a non-magnetic material, it has high noise suppression performance. This characteristic makes it possible to suppress only the noise component while suppressing the influence on the waveform that is the original sound.

● Measurement of acoustic characteristics:
In the verification data of a related product called "Asahi Kasei Palshut MU (support changed to PP)" which uses Palshut as the base material, harmonic distortion analysis (1kHz) shows that the energy level of non-signal waves is approximately 4.71 db. The pink noise analysis results showed that there was almost no change in the sound pressure level.
These results show that Pulshut suppresses the influence on the original sound waveform and only affects the noise component. *Measurement results are typical values and are not guaranteed values.

● Differences between \“NRF-005T\” and \“MWA series\”:
The MWA series is one of the excellent noise suppression materials that is widely used in Oyaide electrical products as a key part of sound quality adjustment.
Since Palshat is a completely new noise suppression material, it has many features that are different from the MWA series. By identifying the right material in the right place based on the characteristics of each, and using them together in your own environment, you can contribute to improving the S/N of your audio system and demonstrating its potential.

● Recommended usage locations:
Speaker cable, line cable (RCA/XLR/TRS/TS), digital cable (USB/BNC/SPDIF),
Around the LAN cable/LAN hub terminal, HDMI cable, around the head shell/cartridge,
Near the connection terminals of speakers and audio equipment, audio interfaces,
Near the terminals of clock generators, oscillators, electronic circuits on semiconductors and substrates (which dislike magnetism)
*The effect increases or decreases depending on the "distance to the noise source". It is recommended that it be attached near contacts or conductive objects that can be sources of noise.
*The suppression effect changes depending on the amount of noise suppression material used, but since Pulshat mainly suppresses noise components, there will be almost no change if there is no noise that can be suppressed.
*Noise suppression effects can be expected even in locations other than the recommended locations. Don't get caught up in the stereotypes, try using a variety of audio equipment.

● Clears RoHS Directive and reduces environmental impact:
The content of environmentally hazardous substances (lead, mercury, hexavalent chromium, cadmium, etc.) is below measurement limits, and the product meets the RoHS Directive.

● Excellent noise absorption effect with simple use:
It's very easy to use. It exhibits a high noise suppression effect by attaching it to the input/output terminals of audio equipment, around areas where noise is likely to occur, or to cables and plugs.
The noise floor is lowered without deforming or distorting the original sound waveform, improving delicate expressiveness with less incidental sound. In addition, you can obtain effects such as reduced blurring of outlines and increased clarity of colors in images. In terms of sound quality, the S/N ratio has been improved, the center of gravity has been stabilized, the localized sound image is in focus, the feeling of noise filling the air gap has been eliminated, the sound field has been expanded, and the image has improved gradation expression. , contributes to improving color development, etc.

● Flexible workability by cutting and pasting with scissors:
It can be easily cut with scissors, has excellent flexibility, and can be attached to curved surfaces such as cables. Excellent processability and workability.
Acrylic adhesive has reworkable adhesive strength, yet has sufficient holding power and can be reapplied many times.
In addition, PET resin is used for the support, so the shape remains stable even after cutting, and the nonwoven fabric can be attached without fraying. The trick to a beautiful finish is to apply light tension when pasting.

● Also for fields other than acoustic applications:
It can be used in various ways as a countermeasure against high frequency noise.
*Example) “Noise countermeasures for devices that dislike magnetism,” “Lightweight and thin noise suppressing material,” “High frequency noise countermeasures for PCs, smartphones, and game consoles,” etc.

● Precautions for use:
1. It can be used in a wide range of temperatures from -20 to 90 degrees Celsius, but please avoid pasting it on areas where overheating or cooling is expected to exceed this temperature (CPU, GPU, vacuum tubes, etc.).
2. Avoid using the product in a way that will hinder heat radiation, such as blocking the heat radiation holes of amplifiers and computers.
3. Avoid storing in direct sunlight.
4. Please avoid storing or using the product in hot and humid conditions as this may cause the adhesive to deteriorate.
5. Thoroughly wipe off any dirt or oil from the adherend (the other side) before pasting.
6. We use reworkable adhesive, but the adhesive strength will weaken if you repeatedly apply and remove it.
7. Although it is designed to prevent adhesive residue from remaining, please do not apply it to areas where you would be concerned about leaving adhesive marks.
8. After pasting, you can remove it by hand, but just in case, avoid pasting it in areas where it would be difficult to remove it.
