AudioQuest Root Beer Active Optical HDMI 4K-8K

Like the well-proven Cherry Cola 18, Root Beer 18 is an active optical cable that provides outstanding audio/video performance at distances up to 100 ft (30 m). Optical Fibre eliminates multiple forms of degradation over distance; powered by the HDMI port, no AC adaptor is required. Further, Optical Fibre provides total RF immunity and galvanic isolation for the audio/video signal, which has important advantages in the fight against radio-frequency noise. As with Toslink and other optical cables, optical fibres do not pick up or transmit induced RF-Noise.

Additionally, Root Beer eARC and communication conductors are direction-controlled to minimise RF Noise that hurts the performance of active circuits.

All AudioQuest High-Speed HDMI cables are capable of Ultra-HD 4K/60 or 8K/30 video. Multiple AQ value-added ingredients enable a surprisingly stronger audio/video experience.

Features

4K-8K - AudioQuest 18Gbps High Speed HDMI cables have the bandwidth required for video up to 8K/30 (8-bit, 4:2:0), which is 7680 x 4320 resolution (over 33 million pixels) at up to 30 frames-per-second (fps). 24 and 30 fps are the frame rates for almost all movies and many TV shows.

18G - All AudioQuest 18Gbps High Speed HDMI cables are guaranteed to have the 18Gbps bandwidth required for compelling features like 8K/30 video, HDR (High Dynamic Range) imagery, and eARC (enhanced Audio Return Channel).

eARC - HDMI hardware’s previous ARC capabilities max out at lossy (compressed) 5.1-channel surround sound. Not only do all generations of AudioQuest HDMI cables “with Ethernet” support ARC, but in order to ensure superior audio performance, the ARC-channel conductor-pair is internally controlled for direction, running in the opposite direction from the 4 pairs that carry information to the TV. Upcoming HDMI 2.1 hardware supports Enhanced Audio Return Channel (eARC), which increases bandwidth dramatically to support uncompressed and lossless high-resolution multichannel audio, including Dolby TrueHD and Atmos, and DTS-HD Master Audio and DTS: X. All AudioQuest HDMI cables “with Ethernet” have the conductors and bandwidth required for eARC’s enhanced sonic capabilities.

HDR - AudioQuest 18Gbps High Speed HDMI cables support High Dynamic Range (HDR) and Dynamic HDR. HDR content expands the contrast of the image for blacker blacks and brighter whites/highlights as well as greater color saturation and brightness. Dynamic HDR (HDR 10+ and Dolby Vision for example) enables frame-by-frame HDR optimization rather than HDR settings that are fixed for the entire program.

Level 4 Noise-Dissipation: Galvanic Isolation + 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. Level 4 Noise-Dissipation features fibres, which are non-conductive and therefore immune to induced RF noise, while the eARC and control conductors are made of direction-controlled metals. Additional Noise-Dissipation techniques (Levels 4+ and up) are applied as budget permits to further reduce noise.
