1~16 XLR broadcast audio fiber Multiplexer

Type:FCA-A16K Message

Description:1-16 channel audio Digital Optical, 24bits sampling, sampling precision 128K, XLR audio interface.

Product Description
  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.
Functional Properties
Ø All-digital fiber optic transmission platform, multi-service platform with flexible configuration
Ø Audio interface XLR balanced XLR interface, audio power supply for the high-power toroidal transformer, + - 18V power supply, high dynamic range;
Ø Provide ordinary desktop mini-desktop, centralized card rack in various ways
Ø 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
Ø Can receive no light is detected, the remote device is a power failure or fiber cut
