1. 4 satellite if inputs and 1 terrestrial TV input, 16 user outputs. Terminal multiSwitch,built-in power supply.
2. Control signal of DVB to switch: 13V / 18V, 0 / 22K.
3. The special preamplifier is used to compensate the signal loss between LNB and switch. Users can use ordinary satellite splitter to divide LNB signal into 4 channels at most, and connect 4 MultiSwitch (RG6 cable should not exceed 50m). The advantage is that the whole system does not need additional amplifiers.
4. Post amplifier is used to compensate the signal loss of the user cable. Cable length from the user to the multiswitch can reach 100 meters.
5. The signal strength of preamplifier can be adjusted to make the system work in the best state.
6. Multi switch built-in 22khz signal generator, compatible with universal Quad LNB and Quattro Quad LNB
7. The terr port has a power switch selector, which can be User request.
8. All signal input ports have independent current protection circuit and lightning protection function design. If one of the ports fails, the other circuits will continue to operate.
9. The built-in AC90V ~ 265V switching power supply is professionally designed, and customers in different regions can customize it for free
10. All connectors are made of gold-plated pure copper, all ports there are extra waterproof gaskets to prevent moisture and water.
11. Our products have environmental tinplate shell and unique luxury plastic frame.
