GeckoFlex 8912RDA AES 110Ω Reclocking Distribution Amplifier

The 8912RDA brings balanced digital audio 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. 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 CommandCenter SNMP-based remote monitoring software.

Key Features
  • 75Ω AES3 or 110Ω AES3 input
  • Eight 110Ω AES3 outputs
  • Autodetect data rate and reclock sample rates from 32 kHz to 96 kHz
  • Lock indicator LED
  • Remote monitoring via Ethernet
