16 Bidirectional XLR Balanced Audio Over Fiber Optic Extender 4U Rack mount- Singlemode Fiber up 20Km LC SFP Include Uncompressed No delay Professional grade Crystal Clear Sound

Professional High Quality 4U Rack mount, Zero latency Crystal Clear Sound Feature: 【XLR Audio over Fiber】The audio over fiber extender can extend 16 channel bi-directional balanced 3 pin XLR broadcast high grade Audio over fiber optic cable to far end. It allows 16 XLR audio device synchronous transmission, No debugging required. 16 XLR Audio signal is transmitted from T (TX) in the direction of R (RX), other 16 XLR Audio signal is transmitted in reverse direction, 4U Rack mount type. 【Long Transmission range】It can work on both single-mode and multi-mode fiber cable. Long transmission distance: Single mode up to 12.4 miles (20Km), ,multi-mode single fiber up to 1640FT(500meters) 【Crystal clear sound, No Loss, No Delay】 Professional quality ,Pure and Clean fiber optic audio signal transmission 【Wide Applications】Typically used in applications for Staging, Theaters, Stadiums, Parks, Broadcast, studio audio and professional AV applications, etc., and are available for stand-alone and desktop type, or wall mounted, installations 【Plug and Play】No need to set up ,Plug and play. Simply plug in an Optical LC port and XLR audio connectors at TX and RX sides, it will have crystal clear sound instantly Attention: The XLR audio fiber extender signal can be outputed to the power amplifier, but the power amplifier audio source can not output the audio source signal to the fiber extender, otherwise the fiber extender will be burned. We suggest that user use the short optical fiber cable to do first time test to ensure that all the functions of the equipment are normal, and then do long-distance transmission.
