HL-4XA Forward XLR Balanced Audio Fiber Extender

Broadcast-Quality Multi-Channel Balanced Audio Delivery The HL-4XA Forward XLR Balanced Audio Fiber Extender is a professional, high-density fiber optic transport system meticulously engineered for the unidirectional transmission of 4 independent channels of balanced analog audio . Featuring industry-standard XLR (Cannon) interfaces, the device utilizes an advanced FPGA-based digital encoding and decoding architecture paired with dual-end clock recovery technology to deliver a highly stable audio link . Designed to meet strict broadcast standards, it maintains complete immunity to electromagnetic and radio frequency interference, making it an excellent option for professional radio and television environments, large-scale concerts, and high-end stadium public address systems . Exceptional Signal Integrity and Integrated Circuit Protection Built to provide crystal-clear sound, the HL-4XA Forward XLR Balanced Audio Fiber Extender boasts a remarkable 100dB dynamic range alongside a greater than 100dB Signal-to-Noise Ratio (SNR) for blast-free operation across a 20Hz to 20KHz frequency response . To maintain pristine audio fidelity, the internal processing includes automatic high-pass filtering to isolate DC offset, as well as intelligent noise control for soft rising and falling waves . For maximum operational security in harsh field deployments, the hardware is equipped with robust Level 3 lightning protection on all XLR interfaces, rated up to IEC61000-4-5 (6KV differential mode) to protect sensitive terminal gear from electrical surges . Flexible Optical Infrastructure and Seamless Plug-and-Play Setup The HL-4XA Forward XLR Balanced Audio Fiber Extender interfaces via standard FC optical connectors and offers dual compatibility with both multi-mode and single-mode fibers . It supports a standard un-relayed transmission reach of up to 1KM over multi-mode configurations, 20KM over single-mode networks, and can be customized up to 100KM for long-haul routes . This entirely hardware-based solution features a true plug-and-play design that requires no software installation or manual adjustments . Sold exclusively as a pre-configured matched pair consisting of a transmitter and receiver, the units include high-visibility front panel LED indicators for real-time monitoring of device power and fiber link connectivity status .
