Legacy multiswitches operate in the 950 to 2150 MHz range and together with a Quatro LNB allow for distribution of DVB-S/S2 satellite programming, DVB-T terrestrial broadcasts, analog FM/ radio broadcasts from one master antenna set to many DVB-S/S2 receivers, TVs, stereos. The job of a multiswitch is to enable any satellite receiver in the system to tune to any satellite channel (polarization/band pair) across the whole range of satellite reception. For this purpose, such a receiver sends via its input and coaxial cable suitable commands (14/18 V supply voltage, 0/22 kHz switching tone, and, in the case of 9-input multiswitches, DiSEqC control signal). The result of the commands is the selection of the adequate input of the multiswitch connected to its output (connected with the input of the receiver).
