Product Description

The 4-channel unidirectional XLR Audio Fiber Extender is engineered for professional multi-channel audio transmission over long distances. It converts four independent balanced analog XLR audio signals into optical signals, enabling stable and interference-free transmission through a single fiber optic cable.

 

Compared with traditional copper-based XLR cabling, which suffers from signal attenuation and electromagnetic interference over long distances, this fiber optic solution ensures pristine audio quality even across distances up to 20km.

 

Each channel operates independently, ensuring excellent channel separation and consistent signal integrity. The device is equipped with high-performance ADC processing to preserve audio clarity, dynamic range, and minimize distortion.

 

Designed for ease of use, the system supports true plug-and-play operation with no configuration required. Its rugged metal housing ensures durability in demanding environments such as broadcasting stations, live stage events, recording studios, conference systems, and security installations.

 

This extender is particularly suitable for applications requiring reliable multi-channel audio transport with minimal latency and maximum stability.
