AudioQuest Root Beer 18 Optical 15m

AudioQuest Root Beer Active Optical HDMI Cable

Audioquest's newest offering in the HDMI market comes in the form of an Active Optical HDMI Cable. These optical HDMI cables are excellent are preserving the HDMI signal over long distances with minimal to no loss, and the AudioQuest optical cables take it one step further with galvanic isolation. It's thanks to this that AudioQuest can reliably offer HDMI signals up to 30 metres with the Root Beer HDMI Cable.

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 100ft (30m). Optical Fiber eliminates multiple forms of degradation over distance; powered by the HDMI port, no AC adaptor is required. Further, Optical Fibers provide total RF immunity and galvanic isolation for the audio/video signal—important advantages in the fight against radio-frequency noise. As with Toslink and other optical cables, optical fibers do not pick up or transmit induced RF-Noise.

Additionally, Root Beer's eARC and communication conductors are Direction-Controlled to minimize 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
• 18Gbps Bandwidth
• Level 4 Noise-Dissipation: Galvanic Isolation + Directionality
• eARC
• HDR
• Limited Lifetime Warranty

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.

18Gbps Bandwidth

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).

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 minimize the RF Noise that damages performance by “directing” or draining it away from the most vulnerable circuits. Level 4 Noise-Dissipation features fibers, 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.

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. New 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 current-generation AudioQuest HDMI cables and earlier models “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.

About AudioQuest

AudioQuest has been the largest cable supplier to the high-end specialist market for many years. AudioQuest is sold in several hundred outlets in the US and in over sixty countries. Bill Lowe (Founder) is especially pleased that this success has been possible despite his insistence that the foundation of the company, and the foundation of AudioQuest marketing, must be the performance of the product. In the audio world, many professionals have learned that it is not always convenient to listen to the products they sell … they might learn something they don’t want to know! Bill has always understood the challenge of basing the existence of AudioQuest on the performance of the product. However, to Bill, this is the only reasonable way to do business and the only acceptable way to combine his passion for music (and all things high performance), with his need to make a living.
