AudioQuest Cinnamon 48 HDMI Cable

Audio quality takes precedence. Despite the attention-grabbing features like 8K video and gaming in HDMI cables, AudioQuest's 48 and eARC-Priority Series stand out as their best-sounding HDMI cables to date. The precision and tight manufacturing tolerances necessary for handling up to 48Gbps bandwidth ensure that AudioQuest's proven ingredients and techniques remain crucial. For instance, Cinnamon 48 boasts 1.25% Silver-Plated Copper conductors, direction-controlled for efficient radio-frequency noise dissipation, along with a metal-layer shield to enhance noise reduction around the 4 FRL + eARC pairs.

48Gbps Bandwidth

AudioQuest “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 AudioQuest’s tried-and-true ingredients and techniques are more important than ever before.

8K/10K

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.

1.25% Silver-Plated Copper Conductors (HDMI)

In AudioQuest HDMI cables, 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—a superbly cost-effective way to maximize a digital cable. Cinnamon 48 uses 1.25% Silver-Plated Copper for its conductors.

LEVEL 3 NOISE DISSIPATION (HDMI): CARBON + METAL + DIRECTION-CONTROLLED

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. 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.

eARC: 1.25% Silver + Level-2 Noise Dissipation

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.
