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 again, the host only has 3 knobs and 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:
10.12 microphone input; Individual gain adjustment for each microphone input; Each microphone input independent phantom power switch; Each microphone input PA/REC mode selection;
11.4 Route Input; 1 external processor breakpoint input; 2 route sound output; 2 auxiliary lines output; 1 remote video conference output;
12.2 professional recording output;
