For systems that use a TV’s e - ARC/ARC output as the audio source, Audio - Quest’s e - ARC-Priority models offer world-class performance at the friendliest possible prices.AudioQuest e - ARC-Priority cables are full-on 48-Series HDMI cables with the 48Gbps bandwidth required for 8K-10K video and all the latest video features. While 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), the eARC data pair and Ground-Reference drain in e - ARC-Priority cables use all the same advanced design ingredients as their “48” siblings. - Vodka eARC features 10% Silver eARC conductors and 5% Silver Ground-Reference conductors with Level-3 Noise Dissipation. - For soundbars and other ARC input-equipped gear, this allocation of design and material resources offers a superb combination of performance and value.48GAudio - Quest “48” HDMI cables can transfer up to professional 10K Ultra-HD video. The 48Gbps bandwidth is made possible by 4 balanced audio/video pairs capable of 12Gbps each. The precision and tighter manufacturing tolerances required to produce HDMI cables that transfer up to 48Gbps bandwidth mean many of Audio - Quest’s tried-and-true ingredients and techniques are more important than ever before.8K/10KAudio - Quest 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.e - ARC conductor with 10% silver content / ground conductor with 5% silver content The AudioQuest eARC Priority HDMI Cables use the same advanced design components as their 48 Series counterparts for the eARC data pair conductors and ground conductor. - This ensures outstanding playback at the best possible price. LEVEL 3 NOISE DISSIPATION: CARBON + METAL + DIRECTIONALITYTraditional “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 4 FRL + eARC pairs to further enhance noise-dissipation. Additional Noise-Dissipation techniques (Levels 4 and up) are applied as budget permits to further reduce noise. - Silver-Plated Copper A/V Conductors (HDMI)In AudioQuest HDMI cables, increasingly thick layers of silver plating are applied to Audio - Quest’s 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—a superbly cost-effective way to maximize a digital cable. Forest 48 uses 0.5% Silver-Plated Copper for its conductors.
