Pearl HDMI features Solid Long-Grain Copper (LGC) Conductors. Specific attention has been paid to maximizing the performance of HDMI, and indeed, AudioQuest's HDMI cables push sonic performance to new levels.
SOLID LONG-GRAIN COPPER (LGC) CONDUCTORS
Long-Grain Copper (LGC) has fewer impurities and fewer internal grain junctions, reducing distortion and digital timing errors.
ETHERNET AND AUDIO RETURN CHANNEL ENABLED
Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy. Some of this energy is stored and then released as distortion. Because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile, Foamed-PE, with its high air content, causes much less of the out-of-focus effect common to other materials.
HIGH SPEED DATA CAPACITY
HDMI standards and capabilities have improved significantly since DVI first evolved into HDMI. All generations are backward compatible. However, not all previous HDMI cables can transmit the full 18Gbps of data required to optimize today’s HDMI 2.0 equipment. While there is currently no 4K/60 4:4:4 software requiring the full 18Gbps capability of HDMI, some sources (UHD Blu-ray players) can be set to “up-sample”, requiring 18Gbps capability. Up-sampling often should be done in the TV rather than in a previous component — but that’s your decision. AudioQuest HDMI cables with "Exceeds 18 G bps" on the box front are guaranteed to exceed the requirements for all possible HDMI data streams.
AudioQuest Pearl, Forest and Cinnamon HDMI make use of Active Frequency-Equalization to enable full 18Gbps/4K UltraHD performance.
