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
