Meguro MBC-3200 FM Multiplex Broadcasting DARC Encoder

MBC-3200 FM Multiplex Broadcasting DARC Encoder

mbc3200

The MBC-3200 is a DARC encoder with modulation function developed for Chinese traffic congestion information system(DARC-RTIC). This unit simultaneously encodes digital traffic congestion information which is sent from traffic information center via WAN into analog signal by DARC-RTIC method. The output signal is input into FM multiplex broadcasting system, used for providing traffic congestion information for large area to drivers by using FM Broadcasting .
