Quality Construction - The four-conductor quad style arrangement cancels electromagnetically induced noise from fluorescent lighting ballasts and AC power transformers. Super Flexibility - Large numbers of thin bare copper wire strands in both the conductors and shield produce a highly flexible cable. Special XLPE Insulation - Excellent electrical characteristics and no shrink-back during soldering. Hand-soldered premium XLR connectors. Varied Selection of Lengths - Available in versions of 1 to 150ft (0.3 to 45.7m).
