REC-absolute-FM Earphone Cable: Advanced Insulation and Pioneering Noise Reduction
Optimal Insulation with Teflon
The REC-absolute-FM earphone cable sets a high standard for sound integrity by employing Teflon as the insulating material. The insulation surrounding a conductor plays a crucial role in maintaining signal quality, as poor insulating properties can degrade conductivity. Teflon is chosen for its exceptional dielectric constant of 2.2, which is significantly lower than the typical polyvinyl chloride (PVC) used in most earphone cables, which has a dielectric constant of 5. The lower the dielectric constant, the better the material is at insulating without absorbing and retaining energy from the electrical signal. This allows Teflon to facilitate a much faster transmission speed, enhancing overall audio clarity and detail.
World’s First Noise Removal Technology
The REC-absolute-FM is at the forefront of audio technology with its inclusion of FINE-MET® by Hitachi Metals, a feature that represents a significant innovation in earphone cable design. This cable is the first in the world to incorporate a noise reduction function designed specifically to target and eliminate transmission noise. The use of FINE-MET® effectively minimizes any potential interference, thereby vastly improving the signal-to-noise ratio (S/N ratio). This breakthrough ensures that listeners experience the clearest, most precise sound possible.
Benefits for Audio Performance
By integrating Teflon for insulation and pioneering noise removal technology, the REC-absolute-FM achieves:
- Enhanced Signal Integrity: The superior insulating properties of Teflon prevent signal loss and maintain the purity of the audio signal, ensuring that the sound delivered to the ears is as intended by the audio engineers.
- Increased Transmission Speeds: With its low dielectric constant, Teflon reduces the time delay in signal transmission, offering listeners a sharper, more immediate audio response.
- Unprecedented Noise Reduction: FINE-MET® technology not only shields against electromagnetic interference but actively reduces noise, setting a new standard for sound quality in earphone cables.
These features make the REC-absolute-FM an ideal choice for audiophiles seeking to maximize their listening experience, providing unmatched clarity and performance in the realm of personal audio.
