1. 16 Satellite IF inputs and 1 terrestrial TV inpupt, 36 user out;Cascade multiSwitch
2. Subscribers pass through select truck signal controlled by 13V\18V  0\22KHz and DiSEqC1.0(2.0)
3A special preamplifier is used to compensate the signal loss and slope of trunk cable and switch trunk channel. The advantage is that the 
    whole system does not need additional amplifiers,the signal has no loss。User amplifier circuit compensates the loss and slope of 
    user signal cable, 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 form LNB.
5Multi switch built-in 22KHz signal generator, compatible with universal Quad LNB and Quattro Quad LNB
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
8External AC90V ~ 265V switching power supply is a professional design. Powerful power and long service life; customers in different regions 
    can customize it for free.
9All F connectors are made of copper. And all ports have extra waterproof shim, so it is moisture proof and waterproof.
10There are LED lamp to show the subscribers using condition.
11Our products have the environmental tinplate shell and unique luxury plastic frame.

Since the switch has built in amplification circuit and a slope compensation circuit, the cascade output port has no signal attenuation and slope loss. This solution greatly improves the reliability of big TV projects. Due to the personalized design of this product, not very professional people can install the system.

The S-Series MultiSwitch of our company is a new generation of intelligent switch. Users usually don't need external amplifier, optical fiber LNB (any LNB can be used), and expensive multi-channel splitter (our company's general SMATV splitter is OK). Technicians should pay attention to this.

Dimensions of EMC171736S and EMC171740S are the same.
