IP Network Audio decoder

  • Model ZP-3011

ZP-3011 is a 1U rack-mount single-channel IP network audio decoder, designed to receive network streaming audio over LAN/WAN and convert it into analog line-level output for connection to conventional amplifiers and PA systems. Built-in decoding circuitry supports IP-based public address, background music and emergency broadcasts delivered from a central server. It is equipped with contact input and output for external trigger, alarm linkage and equipment control, enabling integration with fire alarm, BMS and third-party systems. Ideal for hotels, campuses, shopping malls, office buildings, factories and multi-zone PA systems requiring flexible IP-to-analog audio conversion and remote control.

As a key component for building an IP PA sound system, this adapter simplifies network audio deployment significantly—only one unit is needed to establish a basic IP-based public address framework, reducing the complexity of equipment configuration and lowering initial investment costs. More importantly, it provides a cost-effective solution for upgrading traditional public address systems: by simply adding this IP network audio adapter, users can retain their existing PA amplifiers and loudspeakers, avoiding the waste of existing equipment and minimizing the cost and workload of system renovation.
Designed for wide adaptability, it can be easily integrated into existing LAN/WAN networks without the need for dedicated wiring, supporting flexible expansion of the PA system. It also features stable signal transmission and strong anti-interference capabilities, ensuring clear audio broadcasting even in complex network environments. Suitable for schools, office buildings, factories, shopping malls and other venues, this adapter bridges the gap between analog and digital PA systems, enabling users to enjoy the intelligence and scalability of IP audio technology while maximizing the value of their original equipment.

The IP network audio adapter with decoder is the head of IP PA system.
The IP network audio adapter with decoder can work with universal PA 100 volt amplifier and speakers.
It is high capacity but cost-effective multiple room network sound system.
The system could be set up over existing network, non dedicated network is needed.
System capacity of more than 500 adapters online simultaneously.
Capacity of control power amplifier 1000W.    
Support LAN/WAN and Internet network.
Network data delay of less than 10 milliseconds.
Program controllable power supply of AC 230V or 110V.
