2 Channel XLR Fiber Extender 2CH Unidirectional Analog Audio to Optical Converter
The 2-channel unidirectional XLR Audio Fiber Extender is designed for professional audio transmission over long distances. It converts two independent channels of balanced analog XLR audio signals into optical signals for transmission through fiber optic cables.
Compared with traditional copper-based audio transmission, this device eliminates signal degradation and electromagnetic interference, ensuring stable and high-quality audio delivery even over distances up to 20km.
Its plug-and-play design requires no configuration, making installation simple and efficient. With high-performance ADC technology, the system preserves audio clarity, dynamic range, and minimizes distortion.
This extender is ideal for applications where multiple audio channels need to be transmitted reliably, such as broadcasting, stage performances, recording studios, conference systems, and security monitoring environments.
