DiSEqC 2.0 cascadable distribution system with 9 inputs (8 satellite inputs and one terrestrial input), 9 trunkline outputs and 4 receiver outputs. This type of multiswitch cannot be used as standalone since it does not pass DC voltage from satellite receivers to feed LNBs. On the other hand, DC pass exists for all trunk lines. Therefore it can be used only in conjuction with any 9-inputs standalone multiswitch (S.156 are inserted between standalone multiswitch and LNBs) or with an amplifier, which feeds LNBs (S.156 are connected to the outputs of an amplifier, trunk outputs of last unit must be terminated with 75 ohm resistors). While the first option offers easy way how to extend existing distribution system, second option provides generally higher signal levels on the outputs. In any case, it is recommended to connect up to 5 of these units in a cascade. When higher number of output ports is required, S.158-A multiswitches can be used by the same manner. The product is offered in 5 differnt version (S.156-A-5, S.156-A-10, S.156-A-15, S.156-A-20, S.156-A-25) with satellite band loss stepped from 5 dB to 25 dB to allow level balancing of the distribution system.
