It comes with a dual port hub (HUB) that can be directly connected to a local area network (LAN) or wide area network (WAN) to play network audio and to accept the access and control of servers and other IP network devices.
Network fault self-diagnosis, network and server communication status display
Powerful network audio playback function, can be used independently in the network, can directly play network audio signals from IP network audio matrix, IP network radio head or IP network CD.
It has a backup constant pressure broadcast input port and can be connected to the traditional constant pressure broadcast signal as a backup. When the local IP system fails, it can automatically switch to the traditional constant pressure broadcast to realize uninterrupted broadcast.
With power-off straight-through function, when the device is powered off, it can automatically switch to the traditional constant pressure broadcast.
The backup terminal can accept the control of the server in the main control room and the computer in the sub-control points, and it can also be separated from the server and directly accept the direct control of internal communication intercom equipment such as network fire matrix and network paging microphone. It can respond more quickly and reliably to emergency tasks such as paging intercom or firefighting.
