User manual GRASS VALLEY 8912RDA DATASHEET

[. . . ] [. . . ] This module complements the 8911 AES reclocking DA by offering terminal-screw connectors for those facilities requiring balanced I/O. With built-in impedance conversion, you can select either 75 or 110 inputs. 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 SNMP-based remote monitoring software.
