48Gbps Bandwidth AudioQuest’s “48” HDMI cables can facilitate the transfer of professional 10K Ultra-HD video. This impressive 48Gbps bandwidth is achieved through the utilization of four balanced audio/video pairs, each capable of 12Gbps. The enhanced precision and stringent manufacturing tolerances required for HDMI cables that can handle up to 48Gbps make many of AudioQuest’s established methods and techniques more essential than ever.
8K/10K AudioQuest’s 48Gbps HDMI cables possess the necessary bandwidth to support video resolutions of up to 10K, as well as resolutions and refresh rates reaching 8K/60 and 4K/120. Importantly, all AudioQuest HDMI cables remain fully compatible with existing 4K displays.
5% Silver-Plated Copper Conductors (HDMI) In AudioQuest HDMI cables, layers of silver plating are increasingly applied to the Long-Grain Copper (LGC) conductors to enhance Noise-Dissipation. Positioning this superior metal on the outer surface of the conductor offers the greatest advantage to overall performance, representing an economically efficient means to maximize a digital cable. Carbon 48 employs 5% Silver-Plated Copper for its conductors.
Level 3 Noise Dissipation (HDMI): Carbon + Metal + Direction-Controlled Traditional “100% shielding” proves inadequate in safeguarding against the growing prevalence of Wi-Fi, cellular, and satellite radiation. Within AudioQuest HDMI cables, all 19 conductors are Direction-Controlled to minimize RF Noise, thereby protecting performance through the “directional” draining of noise away from the most vulnerable circuits. Level 3 Noise Dissipation incorporates a high-loss carbon layer, wedged between metal layers surrounding the 4 FRL + eARC pairs, further enhancing noise reduction. Additional Noise-Dissipation techniques (Levels 4 and beyond) are implemented as budget permits to further minimize noise.
eARC: 5% Silver + Level-3 Noise Dissipation Given the paramount importance of sound quality, the eARC conductors in AudioQuest’s 48-Series HDMI cables receive equal attention, featuring top-tier metals, Direction-Controlled Conductors, and Noise-Dissipation technologies, similar to the primary AV data pairs. In AudioQuest’s eARC-Priority cables, the primary A/V data pairs attain 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 employ all the same advanced design components as their “48” counterparts.
Limited Lifetime Warranty AudioQuest HDMI cables adhere to rigorous manufacturing standards and are subjected to thorough quality control. Nevertheless, in the event of a genuine manufacturing defect in your HDMI cable purchased through an authorized AudioQuest US dealer, you are protected by AudioQuest’s non-transferable original-owner limited lifetime warranty. AudioQuest may opt to repair or replace any such defective HDMI cable that has not been subject to abuse for the entire duration of the product’s lifetime. Please note that proof of the original purchase is required. This warranty is not an upgrade program for AudioQuest HDMI cables designed for previous generations of HDMI specifications. The current AudioQuest models are designed to meet HDMI 2.0 (18Gbps) or HDMI 2.1 (48Gbps). Although all generations of HDMI cables offer certain capabilities enabled by HDMI 2.0 and 2.1, not all features are available in each generation. Nonetheless, all generations of HDMI cables are backward compatible, providing all the functions of prior generations. To take advantage of the audio/video benefits offered by the latest HDMI 2.1 hardware, an HDMI cable must meet HDMI specifications, specifically an FRL-enabled bandwidth of 48Gbps. Whether you are using HDMI-enabled equipment with Standard Speed, High Speed (10.2Gbps), 18Gbps, or Ultra High Speed (48Gbps), AudioQuest’s HDMI “48” Series delivers superior audio quality and an exceptional experience, surpassing even AudioQuest’s 18Gbps cables. This warranty is applicable in the United States only. For warranty policies in other countries, please contact your local dealer or distributor.
