DH1700 is an HD-SDI digital video signal Distributor with cable loss automatic compensation and reclocking on the outputs.

It is composed of 1 input and 6 outputs, and it is compatible with the HD-SDI format.

Toward the plug-in center is located a 12 contacts connector on which a DOP107 optional board may be engaged.

The DOP107 optional board, to be used only when it’s present in the input is a 270 Mbit/sec SD-SDI signal, executes the conversion of the input signal to a phase correlated PAL signal on the output.

The DH1700 mounts in its inside an original “watching net” which monitors all the most important nodes in the circuitry and fires the ALARM leds in case of anomaly.
