Cobalt Digital 9253 – 2×4 AES Audio Reclocking Distribution Amplifer, 75 Ohms

The 9253 is a dual AES/EBU distribution amplifier, providing four copies of each incoming signal.  The card supports audio sampling frequencies from 30 kHz to 192 kHz. It can also be used as a 1×8 distribution amplifier, providing eight outputs that are sample rate converted. Cable equalization and reclocking techniques enable the 9253 to reliably recover the incoming digital audio signal.

The 9253 has two 75 Ω  unbalanced AES inputs and four 75 Ω unbalanced AES outputs per AES input. The card can be monitored for status using DashBoard ™ remote control software.
