Description SOLID LONG-GRAIN COPPER CONDUCTORS (LGC) Solid conductors eliminate strand-interaction distortion. Forest's solid Long-Grain Copper allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. OFHC is a general metal industry specification regarding "loss" without any concern for distortion. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance. SOLID HIGH-DENSITY POLYETHYLENE INSULATION Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and then later released as distortion. Solid High-Density Polyethylene Insulation ensures critical signal-pair geometry while minimizing insulation-induced phase distortion. HIGH SPEED DATA CAPACITY All AudioQuest HDMI cables up to 10 meters meet or exceed the 10.2 Gbps maximum data rate for HDMI and are approved High Speed with Ethernet cables. This means that all AudioQuest cables up to 10 meters are capable of transmitting 100% of the data required for all of HDMI's current audio/video features including multichannel high-resolution audio, 1080p and 4k video, and 3D video from Blu-ray. All AQ HDMI cables will deliver 100% of the data required for 120Hz/240Hz/600Hz displays. ETHERNET AND AUDIO RETURN CHANNEL ENABLED All AudioQuest HDMI cables up to 10 meters are rated High Speed with Ethernet. From 12 meters to 20 meters AudioQuest HDMI cables are Standard Speed with Ethernet. DIRECTIONALITY All audio cables are directional. The correct direction is determined by listening to every batch of metal conductors used in every AudioQuest audio cable.
