Audioquest Firebird 48Gbps 72v silver-plated 1m

HDMI cables up to 10K

AudioQuest 48Gbps cables are fully backward compatible with existing devices and have the bandwidth required for video with resolutions up to 10K and resolutions/refresh rates up to 8K/60 and 4K/120.

What is eARC?

eARC stands for Enhanced Audio Return Channel. The difference between ARC and eARC lies in their bandwidth. The enhanced version of the audio return channel has a much higher bandwidth than its predecessor. Bandwidth represents the frequency range or amount of data transferred simultaneously.

Dielectric Bias System (DBS 72V)

Any insulation jacket has the effect of slowing down the signal inside the conductor. If the insulation is non-polarized, it slows down different parts of the signal differently, a major problem for multi-octave audio that is very sensitive to time shifts. AudioQuest’s DBS creates a strong, stable electrostatic field that saturates and polarizes (organizes) the insulation molecules. This minimizes both the energy stored in the insulation and the multiple nonlinear delays that occur. Sound emerges from a surprisingly silent background, offering unexpected dynamic contrast and detail. DBS batteries provide years of operation. A test button and LED allow for occasional battery checking.

HDR (High Dynamic Range)

All AudioQuest HDMI cables support HDR (High Dynamic Range) and Dynamic HDR. HDR content extends the image contrast for blacker blacks and brighter whites/highlights, as well as greater color saturation and brightness. Additionally, 4K Ultra-HD content enables a wider color gamut. This combination of technologies results in more realistic HDR images with greater perceived depth. Dynamic HDR (HDR10+ and Dolby Vision, for example) allows for frame-by-frame HDR optimization rather than HDR settings that are fixed for the entire program. The most well-known current HDR formats are HDR10, HDR10+, and Dolby Vision. AudioQuest 18Gbps and 48Gbps HDMI cables are compatible with all varieties of HDR, which can be found on Ultra-HD Blu-ray and all major streaming services, including Netflix, Amazon Prime, Disney+, Apple TV+, and others.
