Multiswitch designed for cooperation with two Quatro LNBs and terrestrial TV antenna, allowing to build medium and large SMATV systems. It is intended for indoor use only.
An important advantage of MSR-9XX multiswitches is diversification of signal levels at different outputs. It allows to compensate the differences in attenuation of various lengths of cables that have to be used in the installation - we can get similar levels in all outlets. The most distant outlets are connected to the outputs with the highest levels and so on.
Additionally, the multiswitches compensate cable characteristics (provide higher levels for higher frequencies).
Additionally, the multiswitches compensate cable characteristics (provide higher levels for higher frequencies).
The multiswitch is powered with +12VDC to +18VDC. It is possible via "H" lines, from SA-901 (R70901) amplifier. There may also be used local supplier (R71465 18V/800mA).
NOTICE !!!. In the case of using subnetworks and more than one power supply (local supplier or SA-901 amplifier), it is indispensable to separate the subnetworks switching off DC pass in SS-XXX splitter/tap ("OFF" position). Otherwise the power supplies will be damaged.
The following voltages occur at inputs of the multiswitch:
- 18 V DC at H,lo and H,Hi inputs
- 14 V DC at V,lo and V,Hi inputs
