Grass valley 8912RDA-D DATASHEET

8 8912RDA-D Dual AES Reclocking Digital Audio DA

Key Features

•75Ω AES3 or 110Ω AES3 inputs

•Eight 110Ω AES3 outputs, or four 110Ω AES3 outputs per channel when in dual mode

•Auto-detect data rate and reclock sample rates from 32 kHz to 96 kHz

•Lock indicator LED for both channels

•Remote monitoring via Ethernet

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 SNMPbased remote monitoring software.
