"Because A-Net was originally conceived for live stage monitor applications, the protocol was designed to transmit in only one direction: from the A-Net input module or distributor hub out to the performers' mixers," said Carl Bader, president and CEO of Aviom.
"A-Net Pro is fully bi-directional and has dramatically increased capacity, while preserving the central performance specs of A-Net: uncompressed, low-latency in a plug-and-play system. The new version of the protocol carries up to 64 audio channels on a single wire pair in a Cat 5 cable, still at 24 bits. In specialized networks, A-Net Pro can carry 256 channels without sacrificing performance."
