AudioQuest Cinnamon 48 HDMI cables can transfer up to professional 10K Ultra HD video. The incredible 48Gbps data rate is made possible by four balanced audio/video pairs each capable of 12Gbps, enabling a surprisingly stronger audio/video experience. Increasingly thick layers of silver plating are applied to AudioQuest’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. In addition to all 19 HDMI conductors being Direction-Controlled to reduce RF Noise, AudioQuest Cinnamon 48 HDMI cables feature a metal-layer shield around the 4 FRL + eARC pairs to further enhance noise-dissipation. The Audio Return Channel sends audio from the TV to a soundbar, receiver, or ARC input. “enhanced” eARC is easier to use and enables lossless multi-channel. In AudioQuest Cinnamon 48 HDMI cables, the eARC conductor pair is internally controlled for direction to ensure superior audio performance. AudioQuest Cinnamon 48 HDMI cables use Direction-Controlled conductors to minimize RF noise. For optimal Noise-Dissipation and superior audio performance, use Cinnamon 48 HDMI cables with the plug's arrows pointing towards the TV, or Source towards A/V receiver.
