1. The device is designed with embedded computer technology and DSP audio processing technology; using high-speed industrial grade chip, the startup time is less than 1 second.
2. Built-in network IP decoding module, support TCP/IP, UDP, IGMP (multicast) protocol, realize network transmission of 16-bit stereo CD sound quality music signal.
3. Built-in 650W fixed resistance (4-16Ω), constant voltage (70V, 100V) power amplifier output, powerful power, free to choose.
4. Two-way microphone input, two auxiliary signal input, one network and auxiliary signal input, one auxiliary output; realize local external audio input and emergency broadcast input, with independent volume adjustment (device needs to test this function to the site, not satisfied Will not be accepted).
5.1-channel audio signal auxiliary output, convenient to extend the external power amplifier (the device needs to test this function to the site, and the unsatisfied one is not accepted).
6. The main volume, high and low sound adjustment knob can adjust the volume according to the actual situation. (This function needs to be tested when the equipment is on site, and it is not acceptable if it is not met).
7. Intelligent power management, when there is no music or call, the device automatically cuts off the main power and enters the standby state. The standby power is less than 3W, which meets the national energy-saving certification requirements. At the same time, the software can set the pre-open main power time in advance.
8. Manual / automatic: power amplifier power supply, manual automatic switch. (This function needs to be tested when the equipment is on site, and it is not acceptable if it is not met).
