Features:

【Function】This XLR Audio over fiber extender can extend 2 channels of BalancedXLR Broadcast level high quality Audio over an optical fiber cableto far end. It allows 2 XLR audio device synchronous transmission, No debugging required. 2 XLR Audio signal is transmitted from T (TX) in the direction of R (RX). with LC optical interface

【Universal for Fiber Types】The unit can work on both universal single-mode and universal multimodeoptical fiber cable, Long distancetransmission: Singlemodesingle fiber up to 12.4 miles (20Km), Mutlimodesingle fiber up to 0.31 miles(500meters).  

【Crystal clear sound, No Loss, No Delay】Professional Quality ,Pure and Clean fiber optic audio signal transmission.

【Compact design, Sturdy Metal】Bilateral heat dissipation. LEDs for power supply and optical fiber link status indication can monitor the operating status of the system

【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 ,Simply plug in an Optical ST port and XLR audio connectors at TX and RX sides, it will have crystal clear sound instantly.
