HDMI cable 4K-8K from AudioQuest - Ocean - a combination of excellent materials and excellent design, providing the highest quality of digital transmission. The manufacturer has equipped this series with single-core long-grain medium conductors with noise dissipation.
The design of careful design improves sound quality and overall output performance, which in total significantly exceeds the characteristics of previous versions of HDMI cables AudioQuest - Pearl 18G. Naturally, the cable of the Ocean series has a bandwidth of 18 Gbps, which is necessary for such functionality as displaying 8K/30 video, transmitting HDR images (high dynamic range) and eARC (enhanced audio return channel).
What is an important advantage of this cable is the proper orientation of all conductors, including A/V and eARC signals.
AudioQuest High Speed ​​HDMI Cables have the bandwidth required for video up to 8K/30 (8-bit, 4:2:0), which increases the resolution to 7680x4320 (over 33 million pixels) at up to 30 fps (frames per second). 24-30 fps is the frame rate required for almost all movies and many TV shows today.
All AudioQuest High Speed ​​HDMI 18Gbps cables are guaranteed to have the 18Gbps bandwidth required for display features such as 8K/30 video, HDR (High Dynamic Range), and eARC (Enhanced Audio Return Channel).
The previous version of HDMI ARC was maxed out at 5.1 channel compressed surround sound. In addition, all generations of AudioQuest HDMI "with Ethernet" cables support ARC - to ensure excellent audio performance, the conductor of this channel is controlled from the middle in the direction opposite to the 4 pairs that carry information to the TV.
Recommended HDMI 2.1 equipment supports Enhanced Audio Return Channel (eARC), which significantly increases the bandwidth to support uncompressed and lossless high-resolution multi-channel audio, including Dolby TrueHD and Atmos, as well as DTS-HD Master Audio and DTS:X. All AudioQuest HDMI cables "with Ethernet" have the conductivity and bandwidth required for the advanced audio capabilities of eARC.
Advanced Dynamic HDR
AudioQuest 18 Gbps High Speed ​​HDMI Cables support High Dynamic Range (HDR) and Dynamic HDR. HDR content adds contrast to the image for darker blacks and brighter whites/lights, as well as greater color saturation and brightness. Dynamic HDR (such as HDR10+ and Dolby Vision) provides frame-by-frame HDR optimization rather than fixed settings for all programs.
Directional Noise Scattering is the "base" of AudioQuest's noise reduction technologies, although in today's realities, "100% shielding" is no longer enough to protect against the increasing interference from Wi-Fi, cellular, and satellite radiation. AudioQuest HDMI cables feature directional control of all conductors to minimize performance-depleting RF interference by directing it away from its most vulnerable targets.
