1. Any place with Ethernet port can be directly accessed, with dual port hub(HUB), acceptable servers and othersIPAccess and control of network devices.
2. Four completely independentIPChannel input and output, the volume level can be adjusted separately for each channel.
3. Four independent groups of controllable220VAC power output and emergency function. In emergency mode, four sets of power supplies can turn on the output at the same time.
4. Local microphone and line input, each channel can independently select whether to plug in local microphone or line signal.
5. Four independent groupsDC24VThe strong switch power output is used by the strong switch volume controller without the need for additional equipment.
6. You can directly receive network paging microphone control away from the server.
7. 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 realize timed playback (automatically detects the working status of the server and network), ensuring that timed tasks are foolproof (This feature is not a standard feature).
