The 4-channel bidirectional XLR Audio Fiber Extender (1U rackmount) is a professional-grade solution designed for high-performance audio transmission in demanding environments. It enables simultaneous two-way transmission of four independent balanced analog audio channels over a single optical fiber, significantly reducing cabling complexity and infrastructure costs.
Housed in a standard 1U rackmount chassis, this device is ideal for centralized equipment rooms, broadcast racks, and professional AV installations. It supports both input and output on each side (A/B units), allowing full-duplex communication for applications such as intercom systems, stage monitoring, and bidirectional audio distribution.
Compared to traditional XLR copper cables, which are limited by distance and prone to electromagnetic interference, this fiber-based system ensures ultra-stable, noise-free, and high-fidelity audio transmission up to 20km.
Each channel is independently processed with high-performance ADC/DAC technology, ensuring excellent dynamic range, low distortion, and minimal latency. The system is fully plug-and-play, requiring no software configuration, making installation quick and efficient.
Its robust metal construction and rackmount design make it suitable for continuous operation in broadcasting stations, live event production, recording studios, conference systems, and large-scale audio distribution networks.
