4 Channel Bidirectional XLR Balanced Audio to Fiber Optic Extenders with 48V Phantom 1U Rack mount-LC Single-Mode Single Fiber 20Km SFP Include Uncompressed Professional Crystal Clear Sound

Feature:

【XLR Audio over Fiber】This unit can extend 4 Bi-directional 48V phantom XLR balanced Audio over a fiber cable to far end. 4 XLR Audio signal is transmitted from T (TX) in the direction of R (RX), other 4 XLR Audio signal is transmitted in reverse direction

【With 48V phantom power supply】The transmitter uses dual-use XLR Cannon connector , supporting 2 kinds of physical interfaces, XLR Cannon audio line and 6.5mm audio line which can supply power of 48V phantom for Microphones. Each audio supports 48V phantom power switch key, according to the field demand can adjust the phantom power switch, high flexibility

【Long Transmission distance】It can work on both single-mode and multi-mode fiber cable. Long transmission distance: Single mode up to 12.4 miles (20Km), Mutli-mode single fiber up to 0.31 miles(500meters)

【Crystal clear sound,No Loss,No Delay】Professional quality design ,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 ,Simply plug in an Optical LC port and XLR/6.5mm 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.
