Nine Tips for Avoiding Noise from Pickups 1. If the audio cable is connected to another audio device, disconnect it and connect it directly to the Walkman Headphone/Computer for use with normal active speakers for testing. If noise disappears indicating that there is no problem with the monitor itself, check the connected audio device or other aspects.
2. 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 monitoring and headphones can be used.
3. It is best to route the cables separately. Do not use the same cable tray with strong AC power, and try to keep away from strong electromagnetic interference devices such as transformers and luminaire rectifiers. The use of 3X0.5RVVP shielded cable can also effectively avoid external interference, which requires the shield to be grounded at one end.
4. 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 such as amplification, noise reduction, and echo processing. The output of the monitor head is a "LineOut" audio signal of 1Vpp or more.
5. Some video monitors have their own speakers, but they may not work well. Use high-quality headphones or powered speakers to monitor them.
6. The quality of the integrated sound card on some computer motherboards is poor. When recording, it may cause serious noise. Please use a quality independent sound card such as Chuangtong.
7. Check that the volume of the monitor's sound gain potentiometer or amplifier is adjusted properly.
8. Some models of hard disk recorders only focus on video processing while ignoring audio processing may result in poor quality of the synchronized 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.
9. If it is confirmed that the noise originates from the environment, use the Sizheng Power Adapter to effectively filter the ambient noise.
The above is a brief introduction of the pickup to avoid noise. Through these nine tips, I believe that everyone can make the pickup better avoid noise, so as to be better applied in life.
The pickup is the most commonly used convenience in life and is used in conjunction with a video camera to achieve audio and video synchronization. It is also common on various musical instruments and music equipment. But sometimes some pickups often produce noise, and at this time we need to have pickups to avoid noise. The following Xiao Bian will explain to you the nine tips of the pickup to avoid noise.
