What to do if the sound is not handled well

June 17, 2022

The human ear is more sensitive to timbre, and can directly judge whether the sound of PA loudspeaker is realistic or not. Timbre is of great importance in tuning. A little bit of mishandling of timbre will result in monotonous and boring sound, and even worse, serious distortion of musical instruments or singing. Today we are going to share some professional tuner tips of horn speakers!

1. Adjust the bass and soprano
Under normal circumstances, male voices have excess bass, which will be relatively low and lack treble. Generally, the 3kHz frequency band can be compensated to improve the clarity of singing; female voices have too much treble, and the sound is easy to be sharp and the bass is insufficient. Generally, the 400Hz frequency band can be compensated. Compensation can make the sound louder without being too harsh.

2. Adjust the reverberation time
Reverberation determines the length of the reverberation, which is directly related to the color and clarity of the sound. Under normal circumstances, when the bass is singing, the reverberation time can be shortened to improve the clarity of the sound; when the soprano is singing, the reverberation time can be extended to increase the color of the sound of Horn loudspeaker.
If the walls around the tuning scene are made of wood, the reverberation time should be reduced to avoid blurring the sound; if the sound-absorbing materials such as flannel curtains are surrounded by the tuning scene, the reverberation time should be increased to avoid dry sound . It is worth noting that the amount of audience in the scene will also have a certain impact (note: the audience's clothing also has a sound absorption effect), and you can choose a reverberation time between one or two seconds when tuning.

3. Adjust the ratio of direct sound and reverberation sound
When the sound adjustment is in full direct sound without reverberation, the effect of sound beautification will be lost, and it is usually suitable for the tuning scene of conference speech or recitation. According to the needs of the tuning scene, appropriately increase the ratio of the reverberation sound to the direct sound output, which is conducive to simulating natural reverberation sound, making the sound plump and pleasant, and increasing the audience's three-dimensional sense of the scene.
When the sound adjustment is in full reverberation and there is no direct sound, the phenomenon of sound staining will occur, the sound is muddy and distorted. In the case of no special requirements in the scene, the adjustable reverberation and direct sound are divided into half, maintaining a 1:1 ratio output. In this way, the sound will not be distorted and maintain a certain reverberation effect.

4. Adjust the pitch of the accompaniment music
The accompaniment music is tuned according to the singer's tone, and it cannot be adapted to every singer's condition. For example, some people sing in a higher range, and some people sing in a lower range. In order to make the accompaniment music reflect the voice characteristics of each singer, the tuning should have a sensitive auditory response to the singing voice characteristics. When singing, first place the pitch control in the middle position, neither rising nor falling. If the singer can tune up, there is no need to adjust it; if the singer can't sing in the low-pitched area, or the high-pitched area can't keep up, you can adjust the pitch to the vocal area suitable for the singer according to the actual situation.

5. Adjust the ratio of microphone volume to accompaniment music
To sing a good song, the accompaniment music output accounts for 60% in theory. If the singer's tone is good, the volume of the accompaniment music can be appropriately reduced to highlight the singer's singing voice; for example, the singer has shortcomings such as being easy to go out of tune and unable to match the beat. , you can appropriately increase the volume of some accompaniment music to cover up the shortcomings of singing.
When singing scenes, generally do not turn up the volume of the microphone too much. It is even more inadvisable that the volume of the microphone is much higher than the volume of the accompaniment music, which makes the accompaniment sound too weak. Generally, the volume output of the microphone should account for 40%, which is adjusted according to the needs of the scene. The volume of the accompaniment music should not be too strong, so as not to steal the "light" of the singer's voice.
