Heinrich's NAP8 IP network 8 zone audio adapter with a decoder is the primary equipment used in IP network PA systems. It has a built-in decoder that can convert network audio signals into analog signals that can be fed into an analog amplifier. Additionally, it has an 8 zone speaker selector that can split one amplifier into 8 zones to power different loudspeaker zones.

This audio adapter is an ideal sound system solution for multiple room sound systems. It can be set up over existing network LAN/WAN and internet works and can support more than 300 decoders online at the same time. There are eight zone contact outputs to third-party systems available for zone status monitoring. It is designed to be 1U in height and can be mounted on a rack. The power supply is program-controllable and can be set to AC 230V or 110V.
