Both digital and analog wireless microphones are based on the current commercial wired microphones, and the dynamics and sound quality cannot exceed the wired ones. The main performance is
1. The front is only a compromise design affected by static volume
2. The analog fm has a dynamic limit of about 50-70db, and it needs to rely on pre-emphasis, de-emphasis and compression and expansion to be located in the transmitting and receiving sections as "complementary" noise reduction, reducing the inherent noise floor of the wireless channel. The side effects are the ensuing wheezing, the instant side effects brought about by the initiation and recovery time of the companding. It is not serious for human voices and stable instrument sounds, but similar percussion music has fatal problems.
3. Digital wireless can abandon analog dynamic amplitude companding as a whole, but some pure digital wireless has data companding that impairs the sound quality, and this type of digital wireless is based on the pcm method, which has the limitation of sampling frequency and quantization bit accuracy. It will reach the quality of 48k24b, and the high-sampling follow-up system is also useless. Of course, wired microphones do not have this limitation.
4. Anti-interference and confidentiality security are also the advantages of wired microphones.
