Two wires are combined for sound optimisation, improving the cable's capacitive qualities. In studios, the cable is used especially for phantom power or noise cancelling (for noise reduction, the connectors should be crossed over, i.e. opposite wires RED/WHITE and BLUE/YELLOW are combined).
A dense copper spiral shield together with an additional metallized fleece foil guarantee outstanding shielding. Thanks to its intricate construction, this cable is often found in demanding hi-fi studios, where it is extremely popular for its homogenous and leaner sound pattern.
If you are not willing to make a compromise in sound and electronics, this is the cable for you.
