1. It has a backup fixed voltage broadcast input port, which can be connected to traditional fixed voltage broadcast signals as backup.IPWhen the system fails, it can automatically switch to traditional fixed voltage broadcasting to achieve uninterrupted broadcasting.
2. It has a power down direct function. When the equipment is powered off, it can automatically switch to traditional constant voltage broadcasting.
3. Comes with dual-port hub (HUB）,Direct access to local area network (LAN) or wide area network (WAN）,Can play network audio, accept server and otherIPAccess and control of network devices.
4. Powerful network audio playback function, which can be used independently on the network, and can directly play audio fromIPNetwork audio matrix,IPInternet radio orIPnetworkCDnetwork audio signal.
5. With offline function, you can directly accept the control of internal communication intercom equipment such as network fire fighting matrices and network paging microphones away from the server, and respond more quickly and reliably to emergency tasks such as paging intercom or fire fighting.
6. built-in2*15WPower amplifier, full-frequency speaker,The sound quality is beautiful, the power amplifier and the slightly are integrated, making the connection simpler and more convenient to use.
7. When there is no signal, it can automatically turn into standby state, saving energy and environmental protection.
8. Equipped with power amplifier output terminal, which can be externally connected to fixed resistance slightly1Only (4~16Oh,10Winternal power).
9. One line input and one microphone input. The microphone has a strong cut function.
