MK510T/R series digital audio transmission equipments can do digital coding for 1-4 stereos analog audio, meanwhile support 1-4 AES/EBU input. There are three kinds of interfaces which are fiber-optic access, PDH/SDH link interface and microwave transmission radio frequency interface.

Features

     1      Adopt technology of FPGA、digital CODEC and clock-recovery, and have high integration and high stability.

     2      Adapt advanced number processing, clock-recovery and digital codec CMOS chip to have a better performance index.

     3      LED lamp can real-timely indicate working status of the signal.

     4      Make use of the E1 interface of SDH/PDH and radio-frequency channel of microwave to have a point to point transmission of audio signal source.

     5      Cooperating with the E1 interface distributor, it can achieve one-transmitting -to-many-receiving、broadcast model transmitting audio signal source.

6             Apply to province, city, county and town network, and can achieve an extra-long distance transmission audio signal source.
