The S-Video Coupler is designed to extend the distance of your existing S-VHS cable by allowing you to couple two cables together. This allows you to place your DVD player, digital camcorder, satellite system or any S-video-based component away from your TV monitor. The molded design reduces EMI/RFI interference. Connectors: 4-pin mini din Female to 4-pin mini din Female. Use: Allows for coupling of two cables or converts a male port to a female port.
