EMC5508S
Features:
1. 4 satellite if inputs and 1 terrestrial TV input, 8 user outputs and 4 satellite if +1 terrestrial TV Cascadable outputs. Cascadable multiSwitch，External power supply.
2. Control signal of DVB to switch: 13V / 18V, 0 / 22K.
3. A preamplifier is built into the signal input to compensate the signal loss between LNB and switch, so that the cascade output signal and
input signal are balanced without loss, and provide high-quality signal source for the later stage switch. Users can also use ordinary
satellite splitter to divide LNB signals into 2-way and 4-way, parallel 2-group and 4-group MultiSwitch to form a large-scale receiving system.
The advantage is that the whole system does not need additional amplifiers. (see key 2)
4. Post amplifier is used to compensate the signal loss of the user cable. Cable length from the user to the multiswitch can reach 80 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. External 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.

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.
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.
Installation diagram（1）
1. The red button switch is the power switch for terr antenna, which can be turned on if the customer needs to provide power in UHF band.
2. 5way input signal gain adjusting potentiometers are specially used to control the signal strength in the system, especially in the
cascade system, which can balance the signal equalization at all levels.
3. Switch cascade output port. If there is no need to cascade, you only need to install 75Ω AC impedance device at the port,
which can be used as terminal switch. The impedance device can be purchased in local area or can be supported by our company.
