Electromagnetic interference is mainly divided into power transformer interference and stray electromagnetic interference. Generally speaking, the interference of power transformer is caused by the leakage of multimedia speakers. If there are conditions, the effect of installing a shielding cover on the transformer is very obvious, which can block the magnetic leakage to the greatest extent. The shield can only be made of iron-based materials. Try to choose products with big brands and solid materials. In addition, using an external transformer is also a good solution.
Stray electromagnetic interference is very common, and speaker cables, frequency dividers, wireless devices or computer hosts will all become interference sources. The main speaker should be as far away from the computer host as possible to reduce the surrounding wireless devices.
Generally, this situation has something to do with the sound quality. Therefore, you must do your homework, listen to other people's suggestions, or go directly to the audition before choosing the sound. I can give you some good suggestions for your reference.
