1. Convert the digital IP network broadcast data stream into an analog audio signal for use in a combined power amplifier or a pure post-stage power amplifier.,
2. With a 4.3-inch capacitive touch display screen, it supports functions such as modifying the IP of the machine and initiating linkage tasks with one click.;
Specific parameters
1. Standard 2U rack-mounted design, all-aluminum alloy industrial panel;
2. Built-in network IP decoding module, which converts the network data stream into an analog audio signal for use by a combined power amplifier or a pure post-stage power amplifier.;
3. With a 4.3-inch capacitive touch display screen, it supports modifying the parameters of this machine.;
4. Support four shortcut keys for emergency broadcasting, early warning broadcasting, natural disasters, and earthquake broadcasting. Long press the shortcut key to quickly initiate the set broadcast task.;
5. It has 2 controllable external power supply interfaces and intelligent power management functions. When there is no program playback or broadcasting, the output power supply is automatically cut off to achieve energy saving and damage protection.;
6. The 2-channel controllable external power supply has a manual switch button, which can manually turn on the power output without a network signal.;
7. Adopt high-performance ARM architecture chip, support WEB login to modify parameters;
8. It has 5 analog audio inputs: 2 6.3 microphones, 2 RCA lotus line inputs, 1 EMC emergency input; 1 RCA line output, each signal has an independent volume adjustment knob;
9. It has one short-circuit signal output, one short-circuit input, and one 24V signal output.;
10. Support text-to-speech broadcasting;
11. 1 standard RJ45 (10/100M) network switching interface, supporting local area network and wide area network access;
