  • Details
  • Click to view
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 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.

Standard Features

Supports audio sampling frequencies from 30kHz to 192 kHz Cable equalization and data relocking on AES inputs
Configurable as dual 1x4 or 1x8 distribution amplifier Remote monitoring via DashBoard™ software
Five year warranty
