QAM6200 is a prefessional, high quality digital headend transcoder. After the processing of RS encoding, scrambling, interleaving, QAM, wave filtering, finally upconvert frequency signal into RF signal and transmitout. With the advanced QAM modulation, it max supports up to 1024QAM, which greatly promote and optimise the RF output performance.Its service to make it widely applied in DVB-C headend network fields and hotel TV soultions..
