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



1. 12 Satellite IF inputs and 1 terrestrial TV inpupt, 40 user out
2. Subscribers output select truck signal controlled by 13V\18V  0\22 and DiSEqC1.0(2.0)
3Double 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.
4All the input signal can be adjusted to strong or weak, and it also can eliminate the imbalance phenomenon of the 
    signal strength which bring form LNB.
5There 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)
6Terr 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 ~ 265V 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 250V .
9All F connectors are made of copper. And all ports have extra waterproof shim, so it is moisture proof and waterproof.
10. There are LED lamp to show the subscribers using condition.

11. Our products have the environmental tinplate shell and unique luxury plastic frame.
