Product Features: 1, standard 2 10/100M RJ45 network switch interface, support LAN and WAN 2, with 1 local line input, 1 microphone input interface, 1 channel audio output, comes with 2 * 15W power amplifier, can be connected to the fixed resistance speaker; 3, with infrared remote control control, can control the relevant functions of the terminal by remote control 4, with two-way on-demand, free to order the server program through the server software, terminal keyboard and remote control 5, with a USB interface, support U disk playback and recording, real-time recording of local content; 6, audio files support MP3, WMA, OGG, and other formats, broadcast maximum reachable rate: 192K / S (44.1, 16), on-demand maximum reach rate 320K / S (44.1, 16), audio hard decoding; 7, with 3 priority functions, the alarm is the highest priority, network audio playback is the second level, local playback is the third level 8. Providing a terminal feeding speech function, which can feed the sound of the terminal to other designated one or more terminals through the network; 9. The system has an automatic downloading function for queuing, which solves the problem that all terminals download insufficient network bandwidth at the same time, resulting in slow downloading speed; 10. Optional file automatic download and storage function, the file can be downloaded to the terminal in advance. If the terminal detects that the execution task is consistent with the server, or does not detect the server, the task stored by the terminal is directly played. It solves the problem that the network cannot be played when the network fails, and the network bandwidth is insufficient to realize simultaneous playback. Technical features: 1. Optional analog broadcast backup module, when the network broadcast fails, the terminal automatically switches to analog broadcast; 2. Optional TF card module can realize automatic ringing function of disconnected network, and can automatically update the timed broadcast task in the server to the TF card periodically to ensure that the ringing is the latest scheduled broadcast task when the network is disconnected; 3. Optional infrared remote control, not only through the front panel operation button operation, but also through the remote control; 4. Optional 0.3A-24V strong cutting module, can control to open the strong cut volume switch; 5.Optional monitoring module, can monitor the terminal site. 6. Optional text transfer between GSM mobile phone SMS module
