Audio Fiber Mux

1~16 XLR Broadcast Audio Fiber Multiplexer

Overview
1-16 integrated multiplexing audio optical transmitter / receiver using digital coding technology audio interface XLR (XLR) can be audio signals data signals switch signals and Ethernet signals through a single-mode fiber achieve long-distance two-way transmission the maximum signal can be transmitted without distortion-free relay 100Km. Audio interface with 24Bit AD / DA 128K sampling studio-level transmission quality.The fiber audio multiplexer is composed of optical transmitter and optical receiver can be Set to 8 channel bi-directional audio and 16 channel unidirection audio.
Features
◆ All-digital fiber optic transmission platform multi-service platform with flexible configuration;
◆ Audio interface XLR balanced XLR interface audio power supply for the high-power toroidal transformer + - 18V power supply high dynamic range;
◆ Provide ordinary desktop mini-desktop centralized card rack in various ways;
◆ Data interface and audio interface provides three mine-protected through the ITU-T K.21 (10/700 μS) common mode: 6KV impedance (40 Ω) test;
Single fiber transmission optional dual fiber;
◆ Can receive no light is detected the remote device is a power failure or fiber cut;
◆ Audio using 24Bit AD / DA 128K sampling studio-grade transmission quality;
◆ Provides bi-directional asynchronous data (forward and reverse);
◆ Asynchronous data transfer rate than 110-115.200Kbps;
◆ Asynchronous data for RS232 / RS485 / RS422 / Manchester code.
