9251 1x8 AES Audio Distribution Amplifier, 75 Ohms
- Details
- Click to view
The 9251 is an AES/EBU distribution amplifier, providing eight copies of incoming signal. The card supports audio sampling frequencies from 30kHz to 192 kHz. Cable equalization and reclocking techniques enable the 9251 to reliably recover the incoming digital audio signal.
The 9251 has a 75Ω unbalanced AES input and eight 75Ω unbalanced AES outputs per AES. The card can be monitored for status using Dashboard™ remote control software.
Rear modules are sold separately as RM-9251-X for the 10-slot 8310 openGear™ frame, and RM20-9251-X for the 20-slot 8321 openGear™ frame. Also available is the RM20-9251-A/S high density split rear module (5 BNCs per module) for the 20-slot frame.
