Description
Professional Studio-Quality Audio Extension
The HL-2RA Audio Fiber Converter is a high-performance fiber optic transmission system engineered to extend two channels of forward, unbalanced analog audio across extensive distances. Featuring standard red and white L/R RCA interfaces, the device utilizes an FPGA-driven digital encoding architecture to provide a remarkably stable audio link. This uncompressed digital processing successfully delivers high linearity and a wide dynamic range with minimal distortion, generating a studio-quality signal that remains completely immune to electromagnetic interference (EMI).
Advanced Digital Performance and Sampling Specifications
Built to maintain impeccable sonic accuracy for professional environments, the HL-2RA Audio Fiber Converter operates with a standard stereo single-ended configuration and outputs a high-resolution 24-bit serial signal. It offers versatile processing modes, supporting a basic sampling rate of 48 kHz as well as a 96 kHz high-rate mode, operating across a comprehensive frequency response of 10 Hz to 20 kHz. The system maintains precise signal synchronization via an integrated clock recovery technology to guarantee zero transmission latency, and it maintains native protocol compatibility with both I2S bus and MSB formats.
Seamless Field Deployment and Optical Flexibility
The HL-2RA Audio Fiber Converter is a purely hardware-based, plug-and-play solution that demands absolutely no software installation or complex configuration. For reliable field management, the unit incorporates real-time diagnostic LED indicators to monitor power, optical link connectivity, and ongoing operational status. The system is dual-compatible with both multi-mode fiber for distances up to 1 KM and single-mode fiber for a default range of 20 KM, which can be further customized to span up to 100 KM. To achieve correct signal routing, the system must be deployed as a matched pair consisting of a transmitter (TX) hooked to the audio source and a receiver (RX) connected to the speakers or output equipment.
