Functional characteristics
1.Built-in microphone HD distance dynamic sampling analysis circuit, microphone HD pickup radius up to 6 meters;
2. The AFC filtering process of floating point operation technology avoids the sound feedback phenomenon in the field sound reinforcement and improves the sound transmission gain of 6-9dB;
3. On-site sound reinforcement and recording acquisition are processed by different circuits to ensure the quality of recording and sound reinforcement;
4. Intelligent mixing technology is provided to minimize environmental noise and greatly improve the signal-to-noise ratio.
5. Regardless of the distance recording, the voice is clean, recognizable, clear and reducible;
6. Realize the microphone video automatic fixed-point tracking function through the external supporting camera driver;
7. After the system is installed, there is no need to set it again, and the host has only three knobs, each of which is a power switch (line level knob; Amplifier microphone level knob; Microphone level knob
8. Dual 12-way automatic mixing function (PA/REC) to achieve intelligent high-definition audio acquisition; (PA/REC dual mode work at the same time without interference)
9. Rich interfaces to meet the special needs of different industries and different places;
10. Each microphone input individual gain adjustment;
11. Each microphone input independent phantom power switch;
12. Input PA/REC mode for each microphone;
13.1 external processor breakpoint input;
14.2 Route sound output;
15.2 auxiliary line output;
16.1 remote video conference output;
17.2 professional recording output;
