Description：

It is widely used in schools, office buildings, convention centers, alarm centers, railway stations and so on. Based on network digital transmission, it can realize the functions of BGM broadcast, timing ringing task, sound source collection, one-way paging, and so on.

Feature:

*  Standard wall-mounted design, with small size, aluminum alloy structure design, showing with exquisite beauty, excellent workmanship, and elegant appearance.

*  With clear 3.4" LCD screen, with infrared remote control function, easy to operate.

*  The equipment is designed with embedded computer technology and DSP audio processing technology.

*  The built-in network IP decoding module can play network music and do one-way paging in real time. The network delay time of acquisition, playback and one-way call function in the system is less than 100 ms.

*  Built-in high-performance master / standby switch detection module, the switching time between main and standby module is less than 0.3 second in network and power failure,  the switching time between standby and main module is less than 0.3 second after the power and network failure is recovered.

*  One-channel 100V constant voltage signal backup input, it will switch to the backup channel only when the machine has network failure, it can avoid local signal and backup signal cross talk.

*  Built-in broadcasting on-demand acquisition module, can realize real-time broadcasting on-demand function in network media library.

*  Built-in 2 x 30W digital amplifier, less heating , more efficient, CD-class sound quality.
