HL-404TA Bidirec onal Phoenix Terminal Audio Fiber Extender

High-Density Simultaneous Two-Way Industrial Audio Routing The HL-404TA Bidirectional Phoenix Terminal Audio Fiber Extender is a professional, high-density fiber optic transport system meticulously engineered for long-distance, two-way audio networking . The system accommodates 4 independent channels of unbalanced analog audio traveling in both directions simultaneously with zero signal degradation . To fulfil the strict requirements of permanent physical installations, it features industrial Phoenix terminal blocks that allow for secure, screw-down wire terminations . This robust bidirectional architecture makes it an excellent choice for bidirectional industrial public address (PA) systems, multi-zone intercoms, and remote audio feedback links within large-scale command centres . Advanced FPGA Digital Processing and High Fidelity At the technical core of the HL-404TA Bidirectional Phoenix Terminal Audio Fiber Extender is a highly integrated FPGA digital core used for precise encoding, decoding, and dual-end clock recovery . This advanced processing platform completely eliminates high-frequency jitter to ensure maximum timing and signal stability across a comprehensive measurement bandwidth of 10Hz to 20KHz . Delivering studio-grade performance characterised by high linearity, a wide dynamic range, and an exceptionally low-distortion 997 Hz sine wave output, the device generates a high-resolution 24-bit serial output stream . For flexible system integration, it maintains native protocol compatibility with professional I2S bus and MSB formats, supporting a 48 kHz basic sampling rate alongside a 96 kHz high-rate processing mode . Universal Optical Compliance and Maintenance-Free Deployment The HL-404TA Bidirectional Phoenix Terminal Audio Fiber Extender delivers universal optical flexibility, operating seamlessly over both single-mode and multi-mode fiber infrastructures via standard FC optical connectors, with optional support for LC or ST configurations . The hardware spans standard un-relayed transmission distances of up to 1 KM over multi-mode configurations and a default range of 20 KM over single-mode networks, with customisable long-haul options stretching up to 100 KM . This entirely hardware-based solution features a true plug-and-play design, demanding zero software configuration, IP network programming, or manual calibration . Used as a pre-configured pair consisting of a transmitter and a receiver unit, the industrial wall-mount, desktop, and rack-ready devices incorporate high-visibility panel LEDs for real-time monitoring of power, fiber link connectivity, and active audio status .
