The reason why the wireless microphone receiver does not need a volume control

Author:admin   AddTime:2021-08-04

The volume adjustment of the wireless microphone receiver brings confusion in use.

Manufacturers of wireless microphone receivers on the market are habitually treating it as a normal radio, so a volume controller is installed on the control panel to adjust the volume of the receiver, but in actual use, several users know this How to adjust the volume manipulator is the most correct? Even if there are specific instructions in the manual, few people know about it. Therefore, it is often because the volume controller is not properly adjusted, resulting in either the lack of sensitivity and the deterioration of the noise-to-signal ratio, or the full distortion due to excessive output. However, the user mistakenly believes that the reason for the poor performance and poor sound effect of the wireless microphone is the poor sound quality or the lack of dynamic scale of the wireless microphone, which brings great confusion in the application.



The correct description of the output of the wireless microphone receiver.
The output of the wireless microphone receiver must be connected to a mixer or amplifier to be able to pronounce, because the input of the mixer or amplifier has two sockets, "LINEIN" and "MICIN". The former is for normal radio, Inputs such as recorder or CD player; the latter is exclusively for microphone input.

The input characteristics of "MICIN" are mostly based on the sensitivity and dynamic scale of a dynamic microphone. Therefore, after inputting the microphone into the "MICIN" of the mixer, adjust the microphone volume directly on the mixer to get the best results. Excellent sound effect, without the need to adjust the volume of the microphone.
  In the same way, the wireless microphone system uses high-frequency radio waves to transmit the microphone signal. After transmission and reception, the output volume of the receiver is probably accurate to the original sensitivity of the microphone; in other words, the output and input of the wireless microphone system are always The gain is approximately equal to 0dB! According to this criterion, a set of finely depicted wireless microphone receivers can have the same volume output as a wired microphone. The "MICIN" directly input to the mixer can get the best sound effect without installing a volume controller. adjust.
