Our Plenum XLR Balanced cable is suitable for both live sound applications and recording studio applications. For example, if a PA mixing board is more than 25 feet away from the band that it is amplifying, XLR cables are used. Our plenum XLR cables are used for connecting most microphones. Because microphones often require a power source, some mixing boards are designed to provide power. This is called "phantom power." XLR cables allow mixing boards to deliver phantom power to microphones. Most other cables cannot do this. We have used plenum jacketing on this audio cord, which has a variety of benefits, including a high burn resistance and it does not emit toxic fumes when burned. Plenum microphone cables are a great choice for custom pro-audio hookups suitable for use in ducts, plenums and other space used for environmental air without conduit and has adequate fire-resistant and low smoke producing characteristics. Our Plenum XLR cables can only deliver a balanced signal if both devices on either end of the signal are also balanced. Always check with the manufacturer to ensure that a device is balanced.FEATURES:Balanced microphone cable Male NC3MXX to Female NC3FXX Neutrik connectors22 AWG Shielded 2 Conductor Plenum CableOverall Shield 100% Coverage of Aluminum Polyester Foil with Stranded TC Drain WireOur balanced plenum XLR cable comes in a variety of convenient lengths for ease of use.
