Just like the well-established Cherry Cola 18, Root Beer 18 is an active optical cable that delivers exceptional audio and video performance over distances of up to 100 feet (30 meters). Optical fiber eliminates various forms of signal degradation over long distances, and it’s powered directly through the HDMI port, eliminating the need for an AC adapter. Moreover, optical fibers provide complete immunity to radio-frequency interference (RFI) and offer galvanic isolation for the audio and video signal – significant advantages in combating radio-frequency noise. Similar to Toslink and other optical cables, optical fibers neither pick up nor transmit induced RF-Noise.
In addition, Root Beer’s eARC and communication conductors are Direction-Controlled to minimize RF Noise, which can have a negative impact on the performance of active circuits.
All AudioQuest High-Speed HDMI cables support Ultra-HD 4K/60 or 8K/30 video. Several value-added features from AQ contribute to a notably enhanced audio and video experience.
4K/8K AudioQuest’s 18Gbps High Speed HDMI cables are equipped with the necessary bandwidth to support video up to 8K/30, which translates to a resolution of 7680 x 4320 (comprising over 33 million pixels) and a maximum frame rate of 30 frames per second (fps). It’s important to note that 24 and 30 fps are the typical frame rates for the majority of movies and many TV shows.
18Gbps Bandwidth All of AudioQuest’s 18Gbps High Speed HDMI cables come with a guaranteed bandwidth of 18Gbps, which is essential for enabling compelling features such as 8K/30 video, High Dynamic Range (HDR) imagery, and enhanced Audio Return Channel (eARC).
Level 4 Noise-Dissipation (HDMI): Galvanic Isolation + Direction-Controlled Traditional “100% shielding” alone is inadequate to protect against the increasingly pervasive effects of Wi-Fi, cellular, and satellite radiation. In AudioQuest HDMI cables, all 19 conductors are Direction-Controlled to minimize the detrimental impact of RF Noise by guiding it away from the most vulnerable circuits. Level 4 Noise-Dissipation incorporates fibers that are non-conductive, rendering them immune to induced RF noise. Meanwhile, the eARC and control conductors are constructed from direction-controlled metals. If the budget allows, additional Noise-Dissipation techniques (Levels 4+ and beyond) are implemented to further reduce noise.
Quartz Glass QUARTZ GLASS Optical Fiber AV conductors are employed to eliminate various forms of degradation over distance. These conductors are powered by the HDMI port, eliminating the need for an AC adapter.
eARC eARC Previous HDMI hardware’s ARC capabilities were capped at supporting lossy (compressed) 5.1-channel surround sound. All generations of AudioQuest HDMI cables “with Ethernet” not only support ARC but also employ internal control of the ARC-channel conductor-pair for directional purposes, running in the opposite direction from the four pairs carrying information to the TV. The latest HDMI 2.1 hardware introduces the Enhanced Audio Return Channel (eARC), significantly increasing bandwidth to accommodate uncompressed and lossless high-resolution multichannel audio, including formats like Dolby TrueHD, Atmos, DTS-HD Master Audio, and DTS: X.
HDR HDR AudioQuest’s 18Gbps High Speed HDMI cables are compatible with High Dynamic Range (HDR) and Dynamic HDR. HDR content enhances the contrast of the image, resulting in deeper blacks and brighter whites/highlights, along with increased color saturation and brightness. Dynamic HDR (e.g., HDR 10+ and Dolby Vision) enables frame-by-frame HDR optimization rather than fixed HDR settings for the entire program.
Limited Lifetime Warranty LIMITED LIFETIME WARRANTY AudioQuest HDMI cables are meticulously manufactured according to stringent standards and undergo rigorous quality control. However, in case your HDMI cable has a genuine manufacturing defect, AudioQuest provides a non-transferable original-owner limited lifetime warranty that covers cables purchased through an authorized AudioQuest US dealer. At their discretion, AudioQuest will either repair or replace any defective HDMI cable that has not been subjected to abuse, for the lifetime of the product. Proof of the original purchase is a requisite. This warranty does not function as an upgrade program for AudioQuest HDMI cables designed for previous HDMI specifications. Present AudioQuest models are tailored to meet either HDMI 2.0 (18Gbps) or HDMI 2.1 (48Gbps) standards. While all generations of HDMI cables offer some, but not all, of the features made possible by HDMI 2.0 and 2.1, they maintain backward compatibility and provide all the capabilities of previous generations. To fully experience the audio/video advantages enabled by the latest HDMI 2.1 hardware, an HDMI cable must conform to HDMI specifications, specifically offering an FRL-enabled bandwidth of 48Gbps. Whether utilizing HDMI-enabled equipment with Standard Speed, High Speed (10.2Gbps), 18Gbps, or Ultra High Speed (48Gbps), AudioQuest’s HDMI “48” Series delivers superior sound and an exceptional experience, even when compared to AudioQuest’s 18Gbps cables. This warranty is applicable solely in the United States. For warranty policies in other countries, please contact your local dealer or distributor.
