Adjusting the wireless microphone transmitter can improve the sound quality

Author:admin   AddTime:2021-07-26

The inherent noise and limited dynamic range of FM transmission make analog wireless audio transmission have its limitations.

Add pre-emphasis equipment to the transmitter and de-emphasis equipment to the receiver to improve the signal-to-noise ratio of the signal.



The compressor and receiver extender in the transmitter can increase the dynamic range by more than 100dB.

This makes the volume setting very important. If the audio level is too low, a hissing sound will be produced; if it is too high, it may cause distortion.

To obtain a better sound quality, the input gain of the transmitter should be adjusted so that full modulation occurs when a higher volume is produced, but without distortion.
