Cobalt Digital, 9253 2x4 AES Audio Distribution Amplifier, 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 1x8 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 75Ω unbalanced AES inputs and four 75Ω unbalanced AES outputs per AES input. Card status can be monitored using DashBoard ™ remote control software.
