4 in 1 QAM modulator 1. supports 4 channel ASI inputs 2.can work as 4 standalone QAM modulators 3.OEM, ODM available 4 in 1 QAM modulator Summary

4 in 1 QAM is a cost effective integrated QAM modulator designed by Our Company. This device is integrated up to 4 channel QAM modulating carrier outputs, in which each carrier has independent signal channel encoding and direct RF output. Therefore, the device is featured with excellent RF performance index. It supports 4 channel 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.(user can see the different rear panel illustrations in chapter 2.2) Hence, one PCS 4 in 1 QAM modulator can work as 4 standalone QAM modulators, significantly reducing the network operators’ head-end cost. modulator can also support local and remote control to set its working parameters.
