Contrary to their name, Black Labs heritage actually traces back to Newfoundland in the 1700s, when they were first known as Saint Johns Dogs. When this large Newfoundland-based breed was mixed with smaller water dogs, the result is the dog now known as the Labrador. Labradors (Black or otherwise) are known for their dedication to duty, their highly developed sense of smell and hearing, and their endless capacity for playing fetch (they are retrievers after all!). These traits combine to make Labradors excellent service dogs for the handicapped as well as wonderful pets. Solid Long-Grain Copper (LGC) ConductorsSolid conductors eliminate strand-interaction distortion. Black Labs 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. Foamed-Polyethylene InsulationAny 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 released as distortion. Black Lab uses air-filled Foamed-Polyethylene Insulation on both conductors because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile. Thanks to all the air in Foamed-PE, it causes much less of the out-of-focus effect common to other materials. Metal-Layer Noise-Dissipation System (NDS)100% shield coverage is easy. Preventing captured RF Interference from modulating the equipments ground reference requires AQs Noise-Dissipation System. Noise-Dissipation System prevents a significant amount of RFI from reaching the equipments ground plane.
