5% Silver-Plated Copper Conductors and High-Loss Carbon Layer Elevate Performance of AudioQuest Carbon 48 HDMI Cable: Experience 8K Ultra HD Video and Audiophile Sound Able to support all 8K applications and transfer up to professional-grade 10K Ultra HD video, the AudioQuest Carbon 48 HDMI cable features direction-controlled, 5% silver-plated copper conductors for efficient dissipation of radio-frequency noise.

In addition, a high-loss carbon layer sandwiched between layers of metal around the four fixed-rate link (FRL) and eARC pairs further enhances its noise-dissipation capabilities.

Offering audiophile-quality sound to complement its cutting-edge video-based performance for movies, games, and more, Carbon 48 supports resolutions/refresh rates up to 8K/60 and 4K/120. And it is completely backwards-compatible with existing 4K displays.

Carbon 48 also interfaces with all varieties of HDR (including HDR10+ and Dolby Vision), found on Ultra HD Blu-ray and all major streaming services, including Netflix, Amazon Prime, Disney+, Apple TV+, and more.

A limited lifetime warranty, AudioQuest's Level 3 Noise Dissipation, and our 100% Music Direct Guarantee additionally encourage you to experience Carbon 48. Level 3 Noise Dissipation: Carbon + Metal + Directionality Traditional "100% shielding" is not enough to guard against the increasingly prevalent effects of Wi-Fi, cellular, and satellite radiation.

In AudioQuest HDMI cables, all 19 conductors are direction-controlled to minimize the RF Noise that damages performance by "directing" or draining it away from the most vulnerable circuits.

Level 3 Noise Dissipation adds a high-loss carbon layer sandwiched between layers of metal around the four FRL + eARC pairs to further enhance noise-dissipation.

5% Silver-Plated Copper Conductors In AudioQuest 48 HDMI cables, increasingly thick layers of silver plating are applied to long-grain copper (LGC) conductors to improve noise dissipation. Placing the superior metal on the outside of the conductor produces the greatest benefit on overall performance.

Carbon 48 uses 5% silver-plated copper for its conductors. eARC: 5% Silver and Level 3 Noise Dissipation Because sound matters, the eARC conductors in AudioQuest's 48 Series HDMI cables receive equal love and affection, featuring the same superior metals, direction-controlled conductors, and noise-dissipation technologies as the main AV data pairs.

Direction-Controlled and Noise-Dissipation Technologies Traditional shielding is not enough to guard against increasingly prevalent Wi-Fi, cellular, and satellite radiation, especially because all metal conductors act as antennae and pick up RFI.

In AudioQuest HDMI cables, all 19 conductors, including the critically important eARC and power pairs, are direction-controlled, dissipating noise and draining it away from the most sensitive electronics to where it will cause the least harm.

AudioQuest HDMI cables employ multiple levels of noise-dissipation technologies, with the costlier models adding layers of superior high-loss materials to combat RF noise. Ultra-High-Speed HDMI Cable The Ultra-High-Speed HDMI Cable is the first cable defined by the HDMI Forum.

Ultra-High-Speed HDMI Cables comply with stringent specifications designed to ensure support for high-resolution video modes such as 4Kp50/60/100/120 and 8Kp50/60 as well as new features such as eARC and VRR.

Ultra-High-Speed HDMI Cables exceed the requirements of the latest international EMI standards to significantly reduce the probability of interference with wireless services such as Wi-Fi.

HDMI 2.1 HDMI 2.1 is the most recent update of the HDMI specification and supports a range of higher video resolutions and refresh rates including 8K/60 and 4K/120, and resolutions up to 10K. Dynamic HDR formats are also supported, and bandwidth capability is increased up to 48Gbps. Supports HDCP 2.3.
