Hot Sale Big Multiple Dwelling Smatv System Cascade Multiswitch Of 17 In 17out 16 Subscribers 

Multiswitch is an electronic device that allows for connection of any output to any of its input. It is a kind of switch that operates in 950-2150 MHz frequency range (or even to up to 2400 MHz). Connection of terrestrial TV signals (46 to 862MHz) is also possible. All the signals are separated at the outputs of subscribers' outlets.

Such an outlet has three outputs - one with satellite TV signal, to connect SAT TV receiver, second for TV set , and the third for FM stereo. The outlet must be transparent to DC voltage and control signals (DiSEqC and 22 kHz tone) from sat TV receiver. The sat receiver recognizes multiswitch as LNB converter and switching between its inputs is performed by changing voltage sent by the receiver (14V or 18V), presence or absence of 22 kHz signal or in the case of 9 inputs multiswitches - by DiSEqC signal.

Multiswitch ensures that subscribers are able to access satellite signal from any polarization, band and satellite. The variety of installations requires different kind of multiswitches. Basic differences between types of multiswitches are:

1) Number of inputs for converters. It determines ability of reception from different satellites or polarizations;

There are multiswitches with:

• 4 inputs (possibility of reception of all programs from one satellite),

• 8 inputs (possibility of reception of all programs from two satellites)

• 12 inputs (possibility of reception of all programs from three satellites)

• 16 inputs (possibility of reception of all programs from four satellites

• Ensure a free space of 20 cm (7.8 inch) on each side of the unit, upwards a clearance at least 50 cm (19.7 inch).

• Choose an installation place where there is a possibility in case of emergency to get to mains plug and remove it out of the outlet.
2. for the big SMATV system, you need to install BMS1717E trunk amplifier to amplfy the signal to compensate the transmission signal loss.
3. At the big SMATV system end, it better to use the BMS1716E stand-alone multiswitch. If you want not to install the BMS1716E stand-alone multiswitch, Any unused output of the multiswitch must be terminated with 75 ohm resistor.
4. Do not open the multiswitch; otherwise there is a shock hazard.

Be sure with sufficient earthing of the aerials and aerial feeds.
5. This big SMATV system can support up to 512 subscribers.
