GeckoFlex 8912RDA-D Dual AES 110Ω Audio Reclocking Distribution Amplifier

The 8912RDA-D brings low-cost balanced AES distribution to the 8900 family of products. This board 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 board 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 CommandCenter SNMP-based remote monitoring software.

  • 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 re-clock sample rates from 32 kHz to 96 kHz
  • Lock indicator LED for both channels
  • Remote monitoring via Ethernet
