GeckoFlex 8912RDA-D Dual AES Reclocking Digital Audio Distribution Amplifier

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 less outputs per input are required, this module provides a very compact solution. The flexibility of the 8912RDA-D allows you to easily switch 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.

Key Features
