User manual GRASS VALLEY 8912RDA-D DATASHEET

[. . . ] [. . . ] This module complements the 8911 AES reclocking DA by offering terminal screw connectors for those facilities requiring balanced I/O. Where four or fewer outputs per input are required, this module provides a very compact solution. The flexibility of the 8912RDA-D allows you to switch easily between a 1x8 distribution amplifier and a dual 1x4 distribution amplifier. In addition, we've added a powerful remote monitoring capability to enable you to keep track of all your conversion and distribution assets using our NetCentral centralized SNMPbased remote monitoring software.
