3. ion profile Thanks to all the PE Air Tubes it causes much less of the out of focus effect common to other materials NOISE DISSIPATION SYSTEM 100 shield coverage is easy Preventing captured RF Interference from modulating the equipment s ground reference requires AQ s Noise Dissipation System Metal and Carbon Loaded synthetics prevent most RFI from reaching the equipment s ground plane COLD WELD SYSTEM Novel plug design enables a perfect heat free connection between cable and plug XLR plugs are also available King Cobra s gold plated RCA plugs use a patented design that eliminates the distortion caused by the extra contact inside most plugs Because the ground shells are stamped instead of machined the metal can be chosen for low distortion instead of for its machinability A combination of these major ingredients and many more subtle details add up to explain how King Cobra can sound so wonderfully clean clear and dynamic
