The 8912RDA brings balanced digital audio distribution to the 8900 family of products. 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 75Ω or 110Ω 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.
