Axiom Bus Overview
The Attero Tech Axiom bus is a proprietary analog extension
solution that leverages unshielded twisted pair cabling (CAT 5/6)
to transmit two balanced audio channels, RS-232 control and 24V
DC power for audio signal extension applications.
The Axiom bus is designed to support distances of up to 100m
(total run length). The Axiom bus also supports daisy chain
connectivity of up to two Axiom devices to provide flexible
modularity for various audio device connectivity in installed AV
systems.
