product description:

Standard chassis design, 2U aluminum alloy panel. Light touch buttons and user-friendly drawing design, beautiful and practical.

The system's core equipment manages all terminals and can work independently of the server.

Using real-time embedded operating system, high stability and high reliability, without fear of virus intrusion.

High-speed industrial grade (ARM + DSP) chip, startup time ≤ 2 seconds, TFT 4.3-inch LCD screen and control keys.

Unified management of paging microphone / terminal task scheduling, instant display terminal status, system capacity up to 1000 audio terminals.

It has a built-in real-time audio encoder, which digitizes external analog audio, and the signal processing delay is less than 10 milliseconds.

Built-in program play function, can export the server's timed tasks and MP3 files to the SD card, to achieve automatic broadcast to the terminal (supports simultaneous broadcast of 5 channels), this method does not depend on the server, and can be used when the server is turned off .

With microphone jack, optional call handle, to achieve one-way calling and two-way intercom function.

Standard RJ45 network interface, can be accessed where there is an Ethernet port, and supports cross-network segment and cross-route.
