Grass valley 8911 AES-EBU DATASHEET

6 8911 AES/EBU Reclocking Digital Audio Distribution Amplifier

Key Features

•Differential looping input offers excellent common mode rejection (CMR)

•Eight outputs

•Accepts 48, 44.1, and 32 kHz

•Reclocking removes jitter induced by long cable runs

Note: for balanced 110Ω requirements see the 8912 series digital audio distribution amplifiers

	The amount of digital audio is ever increasing
	as studios and broadcast facilities transition	8900V-R
	to digital. The 8911 offers a low-cost method	J1	J2
	of reclocking AES/EBU digital audio signals to
	ensure signal integrity. Best of all, the 8911
	fits into our 8900-V series Gecko frames or	J3	J4
	into a GeckoFlex frame with an 8900V-R
	rear module, which boast passive differential	Outputs	Outputs
