Description:

It is widely applicated to schools, office buildings, convention centers, alarm centers, railway stations and so on. Based on network digital transmission, it fulfills 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,  excellent manufacture technology and marvellous appearance.

*  With 3.4-inch LCD screen, with infrared remote control function, easy to operate.

*  The device uses the industrial dual-core processing chip (ARM + DSP), start time is less than 1S.

*  Built-in network IP decoding module, which can realize real-time broadcast network music and call function; The network delay for capturing playback and call functions is less than 100mS.

*  One way 100V constant voltage signal backup input, it will switch to the backup channel. To avoid local signal and backup signal cross talk.

*  Built-in high-performance master / standby switch detection module, off the network power off the master/ standby switching time is less than 0.3 seconds, on-line power standby / master switching time is less than 0.3 seconds.

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

*  Built-in 2 x30W digital amplifier, less heating , more efficient, CD-class perfect sound quality.

*  With one microphone input and one line input, it is suitable for local live broadcast function.

*  Support connecting with Bluetooth receiver to receive Bluetooth audio for local sound broadcasting.

*  Priority function:

1)The network alarm is the highest priority.

2)Local MIC and AUX is same level,they have higher priority than the network background music.
