Product Overview
The FQ-KN4A-T/R 4-Channel Unidirectional XLR Audio Fiber Optic Extender is a professional digital audio transmission solution designed for long-distance transmission of balanced XLR audio signals over single-mode single-fiber.
The system supports 4 channels of unidirectional balanced audio, with four XLR female inputs on the transmitter and four XLR male outputs on the receiver. Audio signals are digitally sampled at 24bit/192kHz and transmitted over optical fiber at 155Mbps, providing stable and reliable long-distance audio transmission.
The compact 125 × 120 × 40mm design and external 12V DC power supply make the FQ-KN4A-T/R suitable for professional audio systems, live events, stage applications, broadcasting, conference systems, and other distributed audio installations.
