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
to digital. The 8911 offers a low-cost method
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
into a GeckoFlex frame with an 8900V-R
rear module, which boast passive differential
loopthrough inputs, high density, and a wide
range of distribution and format conversion
functions.
