Features:

【Function】This unit can extend Balanced 3pin XLR broadcast quality Audio over an optical fiber cable to far end. It allows XLR audio device synchronous transmission, No debugging required. XLR Audio signal is transmitted from T (TX) in the direction of R (RX).

【Universal for Fiber Types】The unit can work on both single-mode and multimode fiber cable. Long transmission distance: Single mode up to 12.4 miles (20Km), Mutlimode single fiber up to 0.31 miles(500meters). 

【Crystal clear sound, No Loss, No Delay】 Professionally design ,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.
