Description:
It is widely applicated to ordinary classrooms, office, meeting rooms, prisons, hospital departments, subway and other places that need to broadcast recorded voice files or background music.
Features:
* Professional integration wall mounted design, the speaker case subjects to sound resonance principle design concept, with delicated appearance.
* Adopted embedded computer and DSP audio processing technology
* Built 1 channel network hardware audio decoding module that supports TCP/IP, UDP protocol for network transmission 16 CD-quality stereo audio signal.
With 1 AUX input, independent volume potentiometer control
* 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.
* Support routers, switches, bridges, gateways, Modem, Internet, 2G, 3G, 4G, multicast, unicast and other network structure.
* Digital products, easy to expand, without geographical restrictions, no additional room management equipment, adopts network free line construction design, which is  much convenient 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.
* Built-in Level 2 priority function design:
AUX is the same level as the network background music signal, mixing output. Network alarm signals give priority to AUX and network background music signals.
