4 Chnnel ASI MUX-Scrambler Modulator

Overview

4in 1 ASI QAM Modulator with Scrambler multiplexer is a cost effective integrated QAM modulator scrambler

multiplexer designed by SoChuang Company. This device support ASI input. And ASI signal has been sent to

signal processor after synchronized process. After Scrambling-multiplexing and modulation of the signal

processor, then 4RF output with 4 channels DVB-C directly. Therefore, the device is featured with excellent

RF performance index. Hence, one PCS 4 in 1 ASI QAM Modulator with Scrambler multiplexer can work as 4

stand alone scrambler QAM modulators, significantly reducing the network operators’ head-end cost. Also it

can support local and remote control to set its working parameters.
