Videx 319 Active 2 way distribution box

Videx 319 2 way active distribution box compatible with VX2300 system. The unit distributes the BUS signal to 2 outputs linked to videophones or intercoms. The jumper AMP allows the amplification adjustment easy; the related positions corresponding to a medium level (M), low level (L) and high level (H) are marked. The amplification only affects the 2 outputs and not the loop through output. 319 also includes a BUS isolation feature which isolates Art. 319 from the rest of the BUS in case a short on one of its outputs occurs. This prevents a short from happening in any apartment impairing the whole system. Up to 50 devices on the same BUS riser (100 apartments)
