Features:
- Long-Distance Transmission: Extends MADI audio signals up to 10km (6.2 miles) using Singlemode fiber or up to 550m (1804 feet) using Multimode fiber.
- 64-Channel MADI Audio over Bi-directional (1 Strand) Fiber Cable: Converts up to 64 IN and 64 OUT audio channels simultaneously between MADI Optical and MADI Coaxial (electrical) formats.
- Zero Latency & Uncompromised Quality: Features real-time conversion with zero latency and no degradation of signal quality.
- Broad Standard & Cable Support: Features 75 Ohm BNC coaxial connectors supporting AES10-2008 standards and up to 250m cable runs (Belden 1694A).
- Compact & Hot-Swappable: Supports hot-swapping and hot-plugging in a compact, durable package for convenient setup and extension.
Brief Introduction:
The MADI Optical to MADI Coaxial Converter BY-MADI-103 is an all-in-one fiber transmitter and receiver module designed for seamless audio format conversion. Converting up to 64 bidirectional channels between optical and electrical coaxial MADI connections in real time, it preserves complete audio signal integrity without added latency.
Whether expanding complex studio setups or establishing long-distance audio links, this compact unit offers a cost-effective extension solution. Pair two units together to create a reliable, zero-latency MADI extender system over fiber optic cabling.
