Is the pickup sound bad or accompanied by "current sound"?

1, hum (sound)

Usually due to equipment, line filtering and poor shielding, the shielding of the metal casing is better than that of the plastic casing.

Solution: Ground the device case through the wire and replace the shielded wire.

2, sound

Solution: Usually shielded twisted pair cable should be used due to poor audio line shielding.

3, exchange buzz

Usually caused by electromagnetic leakage near the amplifier, such as power adapters, power transformers, mains lines, etc.

Solution: Keep the amplifier away.

4, hum

This problem is difficult for non-electrical technicians to solve due to the quality and performance of the equipment components, circuit design, wiring of the circuit board, and grounding points.

Solution: You can get some improvement by using software to reduce noise or eliminate noise, or use high-end pickups.

5, line induction

Solution: A well-shielded shielded wire should be used due to the mixed sound of more than one of the above mentioned noises due to poor line shielding.

6, hand J interference

During the recording process, someone used the hand J to talk nearby, and the interference when the hand J dialed and started ringing was the most serious.

Solution: Remember not to put the hand J near the recording equipment when recording.

7, display interference

This is due to the radiation noise generated by the line circuit and the field circuit when the display is working.

Solution: Keep the microphone and microphone away from the monitor.

8, display line frequency crosstalk

This kind of interference is different from "7". It is that the horizontal frequency signal of the display passes directly through the display cable to the graphics card, and then to the main board and then into the sound card. It cannot be solved by the microphone away from the display. This kind of problem is easy to appear in some anti-interference ability. On a poor sound card, it is not easy to see this problem based on the investigation of the onboard sound card.

Solution: Only temporarily turn off the monitor during the recording process.

9, host interference

Such interference includes electromagnetic radiation noise generated by the power supply of the host, the main board, the CPU, the expansion slot hardware, and the like.

Solution: Change hardware such as power supply or motherboard. The survey also found that the sound card that comes with the motherboard is not prone to such problems, because the motherboard and the sound card are designed together, the designer considers the mutual interference problem.

Changchun Taiyuan fluoromica Co. Ltd. is located in Changchun high tech Industrial Development zone. It is a high-tech economic entity integrating scientific research, production and management. The company has a strong technical team. There are 1 senior experts and doctoral tutors who have been engaged in artificial lens research for more than 20 years, 1 postdoctoral researchers engaged in nonlinear control research, 1 researchers engaged in inorganic material research, and several senior engineers and engineers engaged in research of related specialties. Strong technical force has laid the foundation for the development of the company in the field of new materials.

To meet the needs of national industrial development, the company has been devoted to the research and development of fluorite mica and its products in 2004. The product is a new material with high temperature resistance, corrosion resistance, low dielectric loss, high volume resistivity, absorption of multi band beam and good transmittance of light. It is transparent, separable, elastic, aging and fragile. It is mainly used in the working environment of electric insulation, neutron test, high frequency medium, high temperature vacuum, high temperature and high pressure, strong acid and strong alkali. It can be used as a substitute for low performance materials such as polytetrafluoroethylene, natural mica and quartz glass.

Our company warmly welcome friends from all walks of life to visit, hope you know the fluorite mica and the use of fluorite mica. Our company will provide free test supplies for scientific research personnel in the high-tech field.

Taiyuan company spirit of "harmony, modesty, pragmat
