IP Network Audio decoder

This IP network audio system and IP PA (Public Address) system server is a core broadcast control device integrating multiple functions, high compatibility and easy operation. Widely applicable to various public address scenarios, it provides an efficient solution for audio transmission and management. Boasting strong compatibility, the device perfectly supports Windows 2000, Windows 7, Win8 and Win10 operating systems, seamlessly integrating into existing office and control systems without additional adaptation.
In terms of network configuration, the server supports the DHCP protocol, enabling automatic IP address acquisition without manual setting, which greatly reduces deployment difficulty and operation and maintenance costs. Equipped with line supervision function and an intuitive UI, operators can quickly get started to manage the entire IP audio system without professional skills, improving work efficiency.
The device comes with a wealth of built-in core functions, including system setup, system monitoring, media player, program timer and system memory modules, meeting the full-process needs of broadcasting in one stop. It supports online playback of cloud MP3 files, and can execute scheduled broadcast tasks to designated loudspeaker zones at preset times via matrix mode, achieving precise audio coverage. Meanwhile, the software can real-time monitor and display the working status of each device, making abnormalities clear at a glance for timely troubleshooting.
In terms of zone management and timing control, the device features flexible multi-level loudspeaker zone definition. Users can assign loudspeakers to as many zones as needed simultaneously to implement diversified broadcast strategies. The built-in weekly timer can broadcast pre-recorded voice messages, bells and songs to selected zones via contact trigger or manual operation, suitable for scenarios such as school class bells and enterprise work schedule reminders.
As a core encoding device, it integrates fire alarm system interface, enabling seamless linkage with IP network audio systems. Once triggered by a closed contact from the fire alarm center, it automatically broadcasts pre-recorded voice alarm messages. Different zone triggers can be assigned unique voice messages, stored in the server or controller for quick access. The fire alarm center sends closed contacts to the fire alarm panel, which communicates with the server via LAN RJ45 port, prompting the server to command specific pre-set messages to designated speaker zones.
The IP network 8-zone audio adapter with decoder serves as the core component of the IP network PA system, integrating decoding and zone control functions to bridge digital network signals and analog audio equipment. Its built-in decoder efficiently converts network audio signals into analog signals, which can be directly fed into analog amplifiers, ensuring stable audio transmission without signal loss. Meanwhile, the integrated 8-zone speaker selector enables one amplifier to power 8 independent speaker zones, realizing flexible audio distribution for multi-room scenarios.
Ideal for multi-room sound systems such as offices, schools and shopping malls, it can be seamlessly deployed on existing LAN/WAN and internet networks, eliminating the need for additional dedicated wiring and reducing construction costs. The device supports over 300 decoders online simultaneously, enabling system expansion to cover large-scale areas. Equipped with eight zone contact outputs, it can connect to third-party devices for real-time zone status monitoring, facilitating centralized management.
Designed as a 1U rack-mount unit, it saves space in equipment rooms and fits standard rack installations for neat arrangement. Its program-controllable power supply supports both AC 230V and 110V voltages, adapting to different regional power standards globally. As a key link in the IP PA system, it works in tandem with remote microphones, fire alarm panels and servers, forming a comprehensive audio solution that balances stability, scalability and operational convenience.
Equipped with a 7-inch LCD touch screen, it features a user-friendly human-machine interface, supporting two-microphone intercom without relying on a server for simplified operation. It offers versatile paging capabilities, including zone paging, group paging, full-zone paging and two-way intercom, adapting to diverse scenario needs. A built-in 3W full-range monitor speaker delivers clear voice restoration with no echo noise, guaranteeing audio quality.
With an SD card input, it can broadcast pre-recorded voice messages and BGM to different zones flexibly. It also enables transmission of local audio sources over the network for expanded application. The microphone is configured with one microphone input, one line input and one line output for seamless connection to sound systems. Powered by 24V DC, it comes with a power adapter in the package. Supporting DHCP, it auto-acquires an IP address without manual setup, integrating smoothly into the IP audio system.
