Product Overview

CS-401 Series Modulator is a cost effective integrated QAM modulator. This device is integrated up to 1 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 1 channel ASI inputs (1 QAM (J.83 A/B/C), 1 DVB-C tuner input or 1 DVB-T tuner input). Alternatively, this device can take various RF inputs of DVB-T/ISDB-T/DVB-C/ATSC-T/DTMB-T signals by installing the relevant build-in tuners. CS-401 Series Modulator can also support local and remote control to set its working parameters.
