Product Description
XLR balanced audio optical transceiver is used for unidirectional optical fiber long-distance transmission of 1-32 balanced audio signals. The front-end balanced audio signal is directly input and output from the back-end through optical fiber transmission. It is connected to an active speaker or a power amplifier to drive a horn. 24bit digital audio coding is adopted, and the system index reaches or exceeds the class a standard of broadcasting.
