User roles: administrator/ordinary user/SIP userSupports up to 1000 partitions, and can make program sources according to user needs, with functions such as timing, partitioning, paging, and alarm; supports multiple remote software operating systems (or web login). Through software settings, each building or each floor can only be responsible for each network audio terminal in this area, and cannot control other areas. It is very convenient to modify and resetSupports standard SIP communication protocol, perfectly combining SIP communication protocol with its own communication protocolSupports GPS and Beidou automatic correction of Beijing time accuracy from 1 minute to 1n second, which can be setReal-time broadcasting, can broadcast to any single point, group, partition or all, or broadcast to any designated area, one-click real-time broadcasting, and each terminal volume can be adjusted separatelyText broadcasting, built-in TTS text-to-speech function, can convert the edited content or text in the text file into speech, support background adjustment of speech speed, number of cycles, setting male or female voice, etc., the voice is clear and naturalTelephone broadcasting: Through the IP network telephone interface, you can access external telephones or program-controlled switches to realize remote telephone broadcasting and publish broadcast notifications anytime and anywhereMobile phone APP: Install special playback software on your mobile phone. You can broadcast and page any terminal or multiple terminals through your mobile phone, play programs to any terminal or multiple terminals, and remotely operate program playback pause/resume, stop, previous song, next song, volume up, volume down, etcRecording: The system has its own recording function, including broadcasting, intercom, real-time acquisition, monitoring and other recordings. You can choose to turn on/off, and the recording list is clear at a glance, which is convenient for viewing and useSupport full-duplex echo cancellation, howling suppression technology (AEC), automatic intercom recording, support intelligent DSS key, users can customize it as speed dial, intercom, answer, hang up and other functions, support background web setting call strategy, support multiple types of call transfer strategies: no response transfer, busy transfer, shutdown transfer and other functionsIt comes with a high-definition camera, supports two-way full-duplex high-definition video intercom, supports full-duplex echo cancellation, howling suppression technology (AEC), and automatic recording during intercomIt supports the scheduled patrol function. After setting the scheduled patrol function, it supports customizing the execution time and repetition cycle of the patrol task, and the flashing interval of the indicator light can be customized from 0 to 30 secondsIt supports multiple emergency plans, supports fire signal access and receives warning information issued by local departmentsIt supports terminal playback monitoring. Any network adapter can be set as a monitor to monitor the program content being played by other network adaptersIt supports on-site ambient sound and monitors the on-site environment of the terminal, such as whether students are listening to the class quietlyIt supports up to 100 timing plans, each of which supports 200 timing points, and the timing plan can be switched at any time; it can flexibly set the repetition cycle (day/month) and playback mode, support scheduled task file playback, terminal acquisition, support one-click activation/deactivation of all plans, and automatic replacement of timing plansRich media library management, support MP3/WMA/WAV/PCM formats, support local audio source upload server, IP audio source (CD/USB/Bluetooth/FM) and server built-in 2-channel audio acquisition external audio source, support WEB remote management of song library, support new/delete/rename song list, upload/delete songs and other operationsSupport online/offline electronic map function, import any project plan, drag and add the terminal to the plan, view the terminal status in real time on the plan, and support full-screen displaySupport broadcast server dual-machine hot standby function, the standby server detects the working status of the main server in real time, realizes automatic switching between the main/standby server, and the standby server can completely proxy the management and control functions of the main serverSupport terminal 100V backup, when the network is disconnected and the power is off, the signal is immediately switched to the analog constant voltage broadcast signal, when the network and power are restored, it automatically switches back to the network broadcast signal, playing a dual signal protection roleAdaptive noise detection function, which can monitor the environmental noise on site and upload the data to the PC host. After the audio algorithm is performed on the on-site noise and the required sound, the volume of the terminal can be adjusted in real time or delayed to maintain the signal-to-noise ratio on siteAutomatic load detection function, supports real-time detection and calibration of 4 lines. The impedance detection range of each line is 20 ohms to 1600 ohms. There are 5 states: short circuit, open circuit, overload, light load, and normal. It supports alarm when the line is abnormalOffline timed broadcast function, built-in 4G memory, supports terminal timed point backup function, and the content of the timed point can be automatically backed up to the network playback terminal. When the server is disconnected from the network, it ensures that the broadcast system is on time, the timed point and the content are broadcast normallyOffline paging function, supports broadcast paging function after the server is disconnected from the networkWireless remote control, the remote control supports 7 function keys, 7 function keys can be set in the background, support new tasks/task switching, pause/resume, stop, previous song, next song, volume up, volume down operations, no need to control playback in the main control room, very suitable for school exercises or sports gamesSupport setting different lighting modes for the terminal, and can customize the red light on, red light off, green light on, green light off time 0.1S-10S respectivelySupport configuration of terminal freezing time, prohibiting the terminal from performing tasks during the period when the terminal is frozen, suitable for scenarios such as exams or restSupport configuration of terminal priority customizationSupport configuration of 10-band parametric equalization sound effect processing and sound effect mode setting of the terminalSupport remote firmware upgrade of the terminal, no need to upgrade locally at the terminal, reducing the workload of maintenance personnelSupport terminal detail export function, support exporting the configuration details of the current system terminal in table form, bringing convenience to system management convenient for viewing and useSupport full-duplex echo cancellation, howling suppression technology (AEC), automatic intercom recording, support intelligent DSS key, users can customize it as speed dial, intercom, answer, hang up and other functions, support background web setting call strategy, support multiple types of call transfer strategies: no response transfer, busy transfer, shutdown transfer and other functionsIt comes with a high-definition camera, supports two-way full-duplex high-definition video intercom, supports full-duplex echo cancellation, howling suppression technology (AEC), and automatic recording during intercomIt supports the scheduled patrol function.
