INTRODUCTIONS
RMC9404 is a professional and high-integrated QAM modulator for multi-channel inputs. It is able to accept 4 or 6 tuner inputs in DVB-S, DVB-S2 or DVB-C mode, 2 or 6 ASI inputs, and 2*IP(UDP) for option. It is integrated with multiplexing and scrambling module, and outputs with excellent QAM modulation index, with up to 4 channels of adjacent frequencies, each of which is independent and directly output by Tuner. This makes the device rather a cost-effective and space-saving item, as if four units were performing with the 4 channels. RMC9404 Four-Channel ASI/Tuner/IP to QAM Modulator is designed in an easy-operating and friendly mode, with convenient local control by LCD or keyboard, and network management by Web NMS. It has been widely applied to digital TV broadcasting, news gathering, interactive services, broadband satellite systems, and so on.
