The AudioQuest Thunderbird 48 4K-10K 48Gbps HDMI cables focus on sound first. While 8K and other compelling video/gaming features make the HDMI headlines, AudioQuest’s 48 and eARC-Priority Series HDMI cables are their best-sounding HDMI cables yet.
The greater precision and tighter manufacturing tolerances required to deliver HDMI cables that transfer up to 48Gbps bandwidth mean all of AudioQuest’s tried-and-true ingredients and techniques matter every bit as much as ever before.
Thunderbird 48 features 10% Silver Plated Copper conductors that have been direction-controlled for the most efficient dissipation of radio-frequency noise; 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.
Technology & Features:
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.
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.
10% 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 maximise a digital cable. Thunderbird 48 uses 10% Silver-Plated Copper for both its conductors and drains.
Level 5 Noise Dissipation: Carbon + Metal + Directionality
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 minimise 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.
eARC: 10% Silver + Level-5 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.
Limited Lifetime Warranty
AudioQuest HDMI cables are manufactured to exacting standards and are subject to rigorous quality control. However, if your HDMI cable has a real manufacturing defect, AudioQuest’s non-transferable original-owner limited lifetime warranty has you covered for cable purchased through an authorised AudioQuest dealer. At its option, AudioQuest will repair or replace any defective HDMI cable that has not been abused, for the lifetime of the product. Proof of original purchase is required. This warranty is not an upgrade program for AudioQuest HDMI cables that were designed to meet previous generations of HDMI specifications. Current AudioQuest models are designed to meet HDMI 2.0 (18Gbps) or HDMI 2.1 (48Gbps). All generations of HDMI cable will provide some, but not all, of the features made possible by HDMI 2.0 and 2.1. All generations of HDMI cable are backwards compatible – they provide all the capabilities of previous generations.
