1, about the microphone whistle,
Usually the howling of the microphone is caused by the excessive volume of the microphone. Look carefully at whether the total microphone volume is too high or the volume of a single microphone is too high.
Another reason for the microphone howling is that the sound quality of the microphone is too high. Listen carefully to the howling frequency: the harsh howling is caused by the high pitch of the microphone, so the high pitch of the microphone must be lowered. If it is a low whistle, the whistle that feels a little vibration is caused by too much microphone bass, so the microphone bass must be lowered.
2. Volume adjustment
Volume adjustment has two purposes: one is to control the dynamic range of sound signals, and the other is to adjust the proportional relationship of various signals. Volume adjustment needs to be combined with sound quality compensation because volume and frequency are inseparable.
Therefore, before tuning, it is necessary to make clear the dynamic level and frequency characteristics of the original sound signal and the proportional relationship between various signals on the spot, which requires repeated audition and debugging, and also takes into account various situations and effects of future playback.
3. In the process of tuning, reverberation usually determines the length of the aftersound, which has a direct impact and feeling on the color and clarity of the sound. Under normal circumstances, such as bass singing, the reverberation time can be adjusted shorter to improve the clarity of the sound. When the soprano sings, the reverberation time can be appropriately extended, and the color and thickness of the sound can be increased to make it sound more tense.
Extended data:
Mixer, also known as mixer, is used to amplify, mix, distribute, modify and process the sound quality of multiple input signals. It is an important equipment for playing and recording programs in modern radio broadcasting, stage amplification, audio program production and other systems.
Mixers can be divided into analog mixers and digital mixers according to the way signals come out.
There are differences in the number of input channels, the number of function keys on the panel and the output instructions of the mixer. In fact, to master the mixer, we should look at it as a whole. Practice makes perfect through practical operation and contact.
The mixer is divided into three parts: input part, bus part and output part. The bus part connects the input part and the output part to form the whole mixer.

Dsp Tuning Skills Many people don't know the tuning method of 3 1, so today Bian Xiao is here to share some of my little experiences, hoping to help you. 1. Generally speaking, if you tune it yourself, cut the frequency to 60hz first, and turn it down to 20000 Hz in Qualcomm. 2. There is also a slope bar. You can try the feeling of the slope yourself. You can choose which one is comfortable and which one is beautiful, and then you can adjust EQ 3. There are three points: 180hz, 800hz and 8000hz. Forming a groove. 4. Other frequencies can be adjusted by yourself, as comfortable as possible, and then if it is delayed, just adjust the left front door. 5. Listen and tune until you feel the sound coming from the middle of the instrument. 6. If you want to tune, you should go to a specialty store, because many unclear things, as well as tuning, are too dependent on your ears, and you can't tune well without a certain level.
