ACU16-C/NHB32-C CobraNet Audio Distribution System
This example shows how multiple AES/EBU channels can be distributed over long distances
(up to 200 meters with 100Base-TX Ethernet cabling) to multiple power amplifiers. The
NHB32-Cs handle AES/EBU to CobraNet conversion, while the ACU16-Cs handle Cobra-
Net to analog conversion. Power amplifier control and monitoring can be performed on
either PC.
