    RV6X4 is the HIFI audio optical transceiver performing 2/4/8-ch high-quality and loss-free HIFI audio transmission over an optical line.

    According to the direction of audio transmission, RV6X4 can be divided into two categories: 2/4/8 unidirectional channel HIFI optical transceiver and 2/4 bi-directional channel HIFI optical transceiver. Refer to Table 1 for the list.

    RV6X4 adopts professional 3-PIN XLR interface, at the transmitting side, the input audio signals are converted to digital signals, and after digital multiplexing, converted to optical signals for transmission; at the receiving side, the photoelectric conversion is completed, and after demultiplexing, output analog signal .

    RV6X4 includes an optical transmitter and an receiver, which can be widely used in audio transmission, television live broadcast, live concerts, high-definition video conferencing, film studios and other fields.

    RV6X4-8A 8-ch unidirectional HIFI 8-ch unidirectional 482mm×44mm×250mm 110VAC~220AC
    RV6X4-2A-2BA 2-ch bidirectional HIFI 2-ch bidirectional 482mm×44mm×250mm 110VAC~220AC
    RV6X4-4A-4BA 4-ch bidirectional HIFI 4-ch bidirectional 482mm×44mm×250mm 110VAC~220AC


    1The size of chassis is the only slight difference between “4-ch unidirectional HIFI” and “4-ch unidirectional HIFI-1U”.

    2“2-ch unidirectional HIFI“ and “4-ch unidirectional HIFI” , “4-ch unidirectional HIFI-1U” and “8-ch unidirectional HIFI “, “2-ch bidirectional HIFI” and “4-ch bidirectional HIFI“ are similar in both panel and application diagram, respectively. so this document will not show the panel and application diagram of “2-ch unidirectional HIFI“ , “4-ch unidirectional HIFI-1U” and “2-ch bidirectional HIFI”.



    n Optical interface
