The 8912RDA-D brings low-cost balanced AES
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. 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 SNMP-
based remote monitoring software.
