NTX-MOD2104-C 4 in 1 QAM is a cost effective integrated QAM modulator designed byDEXIN Company. This device is integrated up to 4 Channels QAM modulating carrier outputs, in which each has independent signal channel encoding and direct RF output. Therefore, the device is featured with excellent RF performance index. It supports 4channel ASI inputs. Alternatively, this device can take various RF inputs of DVB-S/DVB-C/DVB-T signals by installing the relevant build-in tuners. Hence, one PCS 4 in 1 QAM modulator can work as 4 standalone QAM modulators, significantly reducing the network operators head-end cost. MOD2104-C can also support local and remote control to set its working parameters.
