Desktop 4-channel XLR broadcast audio Fiber Mux

Type:FCA-A4Z Message

Description:1-4 channel pure audio digital fiber mux, 24bits sampling, sampling accuracy 128K, audio interface is XLR

Product Description
        1-4 channels integrated multiplexing audio optical transmitter/receiver adopts digital coding technology, the audio interface is XLR (XLR), which can pass audio signal, data signal, switch signal and Ethernet signal through a single-mode optical fiber Realize long-distance two-way transmission, and the signal can be transmitted up to 100Km without distortion or relay. The audio interface uses 24Bit AD/DA, 128K sampling, studio-level transmission quality.
        Audio optical transceivers are composed of optical transmitters and optical receivers, which can be configured into 2 channels of two-way audio and 4 channels of one-way audio.
Functional Properties
◆ All-digital optical fiber transmission platform, flexible configuration of multiple services on the same platform;
◆ Aluminum alloy anodized shell, IP40 protection level;
◆ The audio interface is XLR XLR balanced interface, high dynamic range;
◆ Desktop type, 4U rack plug-in card type are available;
◆ Single fiber transmission, optional dual fiber;
◆ Audio uses 24Bit AD/DA, 128K sampling, studio-level transmission quality;
◆ The audio interface provides three-level lightning protection function, which can pass the test of ITU-T K.21  (10/700 μS), common mode: 6KV, impedance (40 Ω).
