Audio Fiber Mux

8 XLR Broadcast Audio Optical

1-8 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.
Audio Optical by the optical transmitter and optical receiver can be configured with 4 channel audio and 8- channel audio mode.
