The all-metal pickup monitor head can check the following aspects to reduce noise:
1, the Jianting head can not use switching power supply, please use a good 12V ordinary DC power supply. You can use the monitor power supply or adapter specially designed for power supply;
2. If the audio cable is connected to another audio device, disconnect it and connect it directly to the ordinary active speaker for headphones/computer. If noise disappears indicating that there is no problem with the monitor itself, check the connected audio equipment or other aspects;
3. Check whether the noise is caused by the sound self-excitation: The monitor speakers must not be too close to the monitor head, try not to test in the same room. Due to the high sensitivity of the monitor head, the sound of the speaker's feedback to the monitor's microphone will inevitably cause the sound to spur. The same room needs to be monitored. Headphones can be used.
4. It is best to route the cables separately. Do not use the same cable channel with strong AC power, and try to keep away from strong electromagnetic interference devices such as transformers and luminaire rectifiers.
5. It is forbidden to connect the monitor head to the microphone (MIC) input of sound cards, mixers, amplifiers, etc., otherwise the equipment may be damaged. This is because the inside of the monitor head includes a microphone, but it also includes circuits for amplification, noise reduction, and echo processing.
6, some video monitor comes with a horn, but may be poor, please use high-quality headphones or active speakers for monitoring;
7. The quality of the integrated sound card on some computer motherboards is poor. When recording, it will cause serious noise. Please use a quality independent sound card such as Chuangtong.
8. Check if the sound volume of the monitor head sound gain potentiometer or amplification device is adjusted properly;
9, some brand audio distributor quality is not high, will lead to sound bored, cracking, etc., please use high-quality distributor or the company's monitor adapter;
10. Some models of hard disk video recorders only focus on video processing and ignoring audio processing may result in poor quality of synchronous video recording. Please disconnect the DVR first and then directly use high quality headphones or powered speakers to listen to the audio line. If the sound quality is good, it can be determined that there is no problem with the quality of the monitor head;
11. If it is confirmed that the noise originates from the environment, the APM212 noise reduction adapter can be used to effectively filter the ambient noise.
