2. Dual display design makes it easy to operate and provides clear working status display.
3. hasUSBInterface, which can be played directlyUDisk the songs to the designated terminal equipment.
4. It has offline operation function and can be directly connected to the network. There is no need to transfer through the server during paging and intercom, making it extremely convenient and simple to use.
5. supportPCMCoding format, paging speech has almost zero delay.
6. With program programming and scheduled playback function, you can playSDthe cardMP3Songs are programmed to play.
7. Songs from the timer program can be mixed with other inputs from the mixer (such as microphone, computer sound source, etc.) and entered into the network synchronously. solvedIPWhen the digital system timing program broadcasts, it is difficult to mix digital signals with analog signals such as microphone speech.
8. Bring your own high-fidelityMP3Player, playable384KBPScode rateMP3、WMA、OGGand other audio format files. mayUThe music on the disk is converted into network data streams and directly transmitted to other network terminal devices.
9. Full-function two-way intercom, which can directly perform paging and two-way intercom on various types of terminal equipment.
