Solid conductors prevent strand-interation, a major source of dynamic distortion in cables.

5% Silver-Plating is applied to AudioQuest’s Long-Grain Copper (LGC) conductors to improve Noise-Dissipation.

To further reduce RF Noise, Level 3 Noise-Dissipation adds a Carbon Mesh-Network to the Direction-Controlled A/V and eARC conductors.

This is the foundation of AudioQuest’s Noise-Dissipation technologies. 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. Additional Noise-Dissipation techniques (Levels 2 and up) are applied as budget permits to further reduce noise.

This eARC conductor pair features Solid 5% Silver conductors and Level 3 Noise-Dissipation to ensure superior audio performance.

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.

HDMI’s Audio Return Channel (ARC) sends audio from a TV to a soundbar or AV receiver for greater simplicity and flexibility in system setup. Hardware’s previous ARC capabilities max out at lossy (compressed) 5.1-channel surround sound.

Today’s HDMI 2.1 hardware supports enhanced Audio Return Channel (eARC), which increases the digital bandwidth dramatically to support uncompressed and lossless high-resolution multichannel audio, including Dolby TrueHD and Atmos, and DTS-HD Master Audio and DTS: X.

In AudioQuest eARC-Priority cables, the main A/V data pairs have Cinnamon-level performance (Forest 48’s solid 0.5% Silver + Carbon & Vodka 48’s Level-3 Noise-Dissipation), while the eARC data pair and Ground-Reference drain use all the same advanced design ingredients as their “48” counterparts.

Certified Ultra High Speed by HDMI Licensing, AudioQuest's 48Gbps HDMI cables have the bandwidth required to support all HDMI-2.1 features.

The 48Gbps bandwidth necessary for all of HDMI’s new and future features is made possible by upgrading the 4 balanced audio/video channels from 6 to 12Gbps.

Further, AudioQuest 18Gbps and 48Gbps HDMI cables are compatible with all varieties of HDR (including HDR10+ and Dolby Vision), which can be found on Ultra-HD Blu-ray and all major streaming services, including Netflix, Amazon Prime, Disney+, Apple TV+, and others.

High-speed video resolutions render action sequences with lifelike clarity, billiant color, and excellent dynamic contrasts.

AudioQuest 48Gbps HDMI cables have the bandwidth required for video with resolutions up to 10K and resolutions/refresh rates up to 8K/60 and 4K/120. All AudioQuest HDMI cables are completely backwards compatible with existing 4K displays.
