1. Comes with dual-port hub (HUB）,Can directly access the 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. Offline function.It can directly accept direct control from internal communication and 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 and intercom or firefighting.
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. The program on demand function allows you to arbitrarily order thousands of programs in the program library in the server. Users can use the initials to query songs, which is extremely simple and convenient to operate.
6. SDCard plays locally, supports multiple song formats, and high-fidelity sound quality decoding.
7. With high-fidelity recording function, microphone and line signals can be directly recorded and generatedMP3Files and can be called and played at any time.
8. Equipped with an external control trigger port for recording and playback, and an external trigger signal (24Vor contact short circuit signal) can automatically trigger playback, pre-recorded and stored inSDRecording file on the card.
9. 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.
10. LCDThe 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.
11. The AC supply voltage of the power amplifier can be measured and displayed.
12. Amplifier failure alarm prompt.
13. One line input, two microphone inputs, microphone1It has a strong cutting function.
14. When there is no signal, it can automatically turn into standby state, saving energy and environmental protection.
