The distributor DH1700-3G is the enhanced version of the popular Dh1700. It is now compatible with 3G/HD/SD and offers 7 outputs instead of 6.
Some features, like the automatic compensation of the losses of the incoming cable, have been improved while the performance with 3G signal is at the top of its category.
In line with current trends, the reclocking can be excluded.
A monitor circuitry on the static levels of the output drivers provides the visual alarm by red led in case of fault.
