Description:

It is widely been installed in classroom, multi-media classroom, office, conference

room, prison, hospital office, metro, and other places, to broadcast some background music, and to be used as local broadcast.

Features:

*  Professional integration wall mounted design, the speaker case designs is conform to sound resonance principle design concept, with excellent appearance.

*  Adopt embedded computer and DSP audio processing technology

*  Built-in one network hardware audio decoding module, it supports TCP/IP, UDP, to realize the network transmission of 16-bit CD-quality audio signals.

*  Built-in 2 channel digital amplifier 2-20W , 1 channel to connect main speaker, the other to connect sub-speaker , with smooth and strong sound quality, and network volume setting.

*  Built in high performance main/standby switching module, Off the net Power failure Master / standby switch time less than 0.3 seconds, and the standby/main switching time is less than 0.3 seconds when the network is powered on.

*  With 1 AUX input, independent volume potentiometer control, support offline local paging function. Support mute volume preset and background music mix output preset.

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

*  Built-in simulation audio signal backup module, it supports 100V signal input. It can  switch into simulation audio signal in case of network failure or power off,  to achieve dual-line redundancy.

*  Built in with 2.4G wireless audio module, Transmission frequency: 2.4000—2.53MHz, HIFI, good anti-interference ability.  Support 2.4G wireless microphone for local broadcasting.It has the highest 64K @16bit×2 in the field, and has HDCD sound effect. The sound delayed (<0.5ms).Frequency response: 80—16KHz.

*  2.4G mic supports volume adjustment function.

*  It realizes the encryption transmission and the receiver supports the automatic sweep frequency function to avoid the interference easily.

*  It will enter the pairing status automatically when turn on, after pairing successfully, it will have the prompt tone with indicator light to shift to the receiving status automatically.

* Connection distance of automatic pairing between the controller and mic is ≤3 m, pairing connection time ≤3 s.

*  Charging function, with charge management, support to charge when working, TYPE-C socket for charging, general mobile phone charger.

*  The frequency distance (power) can be set by self.

*  Working distance up to 10 meters. (depending on usage environment ).

*  Built-in 2 priority level setting:

1) Network voice alarm has higher priority than AUX and Network BGM.

2) AUX has higher priority than Network BGM.

*  Support local AUX and 2.4G wireless audio input when network offline, meet the local broadcast requirement.

*  Compatible with any network structure such as routers, switches, bridge gateways, Modem, Internet, 2G, 3G, 4G, etc.

*  Easy extension, no geographic location restriction, no need additional managerial equipment, adopted design concept of common network-free line construction, easy to install.

*  It supports remote hardware upgrade of the terminal, no need go to upgrade at the local site, to reduce maintenance burdens and make more simple operation.
