SOLID SILVER 5% CONDUCTOR: Drivers eliminate beach interaction distortion and reduce jitters. This is a very high quality cable of the case. Polyethylene air pipe insulation: dielectric bias system DBS, Carbon Noise Dissiction System (NDS): 4 layers of metal and carbon-loaded plastics plus RFI to prevent the ground level of the equipment from being reached. Triple-balanced geometry: the 100% cover shield is never used as an inferior rider. XLR sockets factory completed. Male on one end and female connector on the other end. Grounding: Sometimes there is a hum problem unless the subwoofer and surround sound AV receiver (or processor) are connected with a separate cable. If your system has a hum problem, try connecting it to the metal housing of the subwoofer amplifier and the housing of sending the components with little spade-lug tails. Normally this extra cable is not needed.
