How do the latest network-attached IP audio systems work? The latest digital IP systems use protocols that are similar to Voice over IP (VoIP) protocols. This communication method also uses Power over Ethernet (PoE) to power the telephones, IP paging systems, and IP intercoms.
These IP audio systems use the network cable rather than using individual wires that go from an amplifier to a speaker. What is the magic behind sending multiple paging announcements on the same wire at virtually the same time?
Arthur C. Clark said, “Any sufficiently advanced technology is indistinguishable from magic.”
Here’s how the magic works.
