Digital TV Headend 4 in 1 SD Mux-Scrambling QAM Modulator,(DT-MSQAM-4SD) is a high performance and cost-effective
mux-scrambling encoding QAM modulator designed by DAYTAI. It has multiple input ports optional. After encoding, multiplexing,
scrambling and QAM modulating process, then it gives RF output. To meet customers’ various requirements,
this device is also equipped with Tuner input to extend the signal source. Its pluggable structure design greatly facilitates the
change of modules (demodulator or encoder ect) as needed.The device is also characterized with high integrated level, high
performance and low cost. This is very adaptable to newly generation CATV broadcasting system.Power: AC 100V±1050/60Hz;
AC 220V±10%, 50/60HZ,Power Plug:European standard Plug or American standard Plug is optional.
