Application:
It is widely applicated to ordinary classrooms, multimedia classrooms, offices, meeting rooms, prisons, hospital departments, subway and other places to play a recorded voice file or background music. It also can be used as a local PA broadcast.
Features:
* Professional integration wall mounted design, the speaker case designs is conform to sound resonance principle design concept, with excellent appearance.
* Adopted embedded computer and DSP audio processing technology.
* Built-in one channel 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 x 20W, 1 channel to connect main speaker, another connect sub-speaker to fulfill smooth and strong sound quality, with network volume setting.
* Built-in high performance main/standby switching module, off the net Power failure main/ 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 2.4G wireless audio module can be expanded to realize local amplification of the 2.4G wireless microphone.
*Support connecting with Bluetooth receiver to receive Bluetooth audio for local sound broadcasting.
* 1 channel 100V constant voltage signal backup input, only switch to the backup channel when the machine has no network.,to avoid crosstalk between local signal and backup signal.
* Built-in 2 priority settings:
1) Network voice alarm has higher priority than AUX and Network BGM
2) AUX has higher priority than Network BGM
* 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.
