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.
