For professional audio and critical communications, the Belden 9451PS4 plenum audio cable delivers dependable, low-noise performance where it matters most. This plenum-rated audio snake cable is engineered to simplify large installations with a full 1000' reel of 4/22 AWG, 4-pair conductors that reduce splices and speed deployment across stadiums, studios and enterprise facilities. Individual shielding on each conductor minimizes electromagnetic and radio-frequency interference so surveillance, security paging and monitoring systems retain clear, intelligible audio even in electrically noisy environments. Constructed with tinned stranded copper and FEP/PVC insulation, the cable resists corrosion and remains flexible for repeated handling during installs and reconfigurations.
