Custom Cable Connection microphone cables are a great choice for custom "pro" audio hookups to connect microphones to PA amplifiers, mixers or extension cords. These hookups are balanced, which helps cut out noise and hum pickup. A balanced line consists of three paths of current flow, using a pair of twisted wires with a shield covering them. The twisted pair would carry the actual audio signal while the overall shield acts as a noise absorbing barrier. The shield is typically connected to ground. The outer jacket is constructed from a durable, ultra-flexible matte black PVC compound.
