1. 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.
2. 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.
3. 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.
4. Audio channel selection and listening function allows users to choose and listen to multiple audio channels simultaneously transmitted audio programs, Audio channel programs can come from the server, or from the audio matrix orIPInternet radio andIPnetworkCD。
5. SDCard plays locally, supports multiple song formats, and high-fidelity sound quality decoding.
6. Unique local storage and playback function for timed tasks. Timing programs and songs can be downloaded to the computer. Even when the network is disconnected and the server is interrupted, it can be played regularly, ensuring that timed tasks are foolproof.
7. VFD The display comes with a high-precision electronic clock, time display function, and the clock can be automatically synchronized with the server to ensure accurate execution of scheduled tasks.
8. One line input and one microphone input. The microphone has a strong cut function.
9. built-in2*15WStereoscopic digital power amplifier, low temperature rise, safe and reliable, suitable for long-term work.
10. When there is no signal, it can automatically turn into standby state, saving energy and environmental protection.
11. Full-function remote control (remote control and remote control components are optional).
