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.

 

In AudioQuest HDMI cables, Solid Long-Grain Copper, Silver-Plated Copper, or Perfect-Surface Silver conductors improve Noise-Dissipation and overall performance. The flagship model of our 48 Series, Dragon 48, uses AudioQuest's best conductor metal, 100% Perfect-Surface Silver, for both its conductors and drains.

 

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. In Level 5 Noise-Dissipation, high-loss graphene is added to the carbon layer sandwiched between layers of metal around the 4 FRL + eARC pairs, and a "global" high-loss carbon layer is placed around all conductors. Level 6 Noise Dissipation, AudioQuest's most advanced and comprehensive means of addressing induced radio-frequency noise, incorporates all of the sophisticated techniques found in other models and adds AudioQuest's patented 72v Dielectric-Bias System.

 

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. 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. 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.

 

AudioQuest HDMI cables are precisely manufactured to ensure a high level of reliability and are backed by a non-transferable, limited lifetime warranty. Proof of original purchase is required; other restrictions apply.
