Zhuhai E.M.C Electronic Technology Co.,Ltd


1.  4 satellite IF input and 1 terrestrial TV input, for 8 users output.
2.  Subscribers output select truck signal controlled by :13V / 18V ,0 / 22K.
3.  Double built-in amplifier circuit, front-end amplifier circuit is used to compensate the LNB input signals 

     of cable. After end amplifier circuit is used to compensate the users signal cable. The cable length 

     from LNB to multiswitch can be up to 50 meters, and the cable length from multiswitch to users can be

     up to 100 meters.
4.  All the input signal can be adjusted to strong or weak, and it also can eliminate the imbalance phenomenon 
     of the signal strength which bring from LNB
5.  There is the built-in 22KHz signal generator in this multiswitch, which can automatically drive by

     universal LNB (different kinds of LNB can be used with this multiswitch)
6.  Terr port has power supply switch selector, which can provide power to antenna system according to the 
     users request.
7.  Each signal input circuit is independent of the current protection circuit. And if one external short circuit will 
     stop working, other circuit still continue to work.
8.  External AC90V ~ 265 V switching power supply is a professional design. For the professional test report, 

     this multiswitch won’t be burned or broken even by more than 50 ℃ of daily temperature in summer or

     under higher than unstable voltage on about 250 V .
9.  All F connectors are made of copper, which is plated copy gold color for the surface. And all ports 
     have extra waterproof shim, so it is moisture proof and waterproof.
10. Our products have the environmental tinplate shell and unique luxury plastic frame.
