Four-Channel Audio Fiber Extender
This YINGHUA unit sends four balanced audio channels over a single SC optical fibre up to 20 km. It targets installers who need long-distance, noise-free audio links for venues, classrooms or broadcast sites. The transceiver pair ships with an EU mains plug for immediate deployment. No local configuration is required once the fibres are connected.
24-bit 96 kHz Digital Sampling
The link digitises each channel at 24-bit depth and a 96 kHz sample rate, preserving full dynamic range across the fibre. Balanced XLR connectors present a 10 kΩ input impedance and a 600 Ω output impedance with a unity gain ratio. This specification decides whether the extender matches your console, mixer or PA system interfaces.
Immunity and Power Draw
Optical transmission eliminates electromagnetic interference, radio-frequency pickup and ground-loop currents, so the signal stays clean in harsh electrical environments. The adaptive optical engine needs no manual alignment or gain adjustment during operation. Power consumption remains low enough for standard mains supplies without additional cooling.

Questions about this item
What does 24-bit/96 kHz sampling mean for audio quality in my setup?
It provides high-fidelity digital audio transmission with a 1:1 input-to-output amplitude ratio across four balanced XLR channels.
How does the SC fiber interface limit the transmission distance?
The SC optical fiber supports a default 20 km range, extendable up to 120 km, with no electromagnetic or radio frequency interference.
What connectors and impedance levels do I need to match for installation?
It uses balanced XLR connectors with 10K ohm input impedance and 600 ohm output impedance for professional audio gear.
