AudioQuest Root Beer 18 Active Optical (AOC) High Speed HDMI Cable

Root Beer 18

Long-Length High Speed 18Gbps HDMI 2.0b Cable

AudioQuest Root Beer 18 is an active optical cable that provides outstanding audio/video performance at distances up to 100ft (30m). Optical Fibre eliminates multiple forms of degradation over distance; powered by the HDMI port, no AC adaptor is required. Further, Optical Fibres 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 fibres do not pick up or transmit induced RF-Noise. Additionally, Root Beer's eARC and communication conductors are Direction-Controlled to minimise RF Noise that hurts the performance of active circuits.

Key Features & Technology Explained

Quartz Glass Zero Loss Over Length

Optical Fibre AV conductors eliminate multiple forms of degradation over distance.

Level 4 Galvanic + Direction Controlled A/V Noise Dissipation

To further reduce RF Noise, Level 4 Noise-Dissipation adds Galvanic Isolation to the Direction-Controlled A/V and eARC conductors.

eARC LGC Level 1 ND

This eARC conductor pair features Solid Long-Grain Copper conductors and Level 1 Noise-Dissipation to ensure superior audio performance.

18Gbps Bandwidth

AudioQuest’s 18Gbps 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).

4K-8K Resolution

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.
