Do you really know this about stage sound equipment?

What is a coaxial speaker? General speakers, high pitch units and bass units are flat arranged on the panel of the speaker, so their sound center can not coincide as a point, so that the distance between the high pitch and bass to the listener is different, th...

Settings and control of professional stage sound system【二】

As for the professional stage sound control, the performance generally needs to change a variety of scenes, but the stage replacement takes a long time and the effect is unknown.Therefore, the direct use of audio equipment to create a variety of stage atmosphere is efficient and convenient. Sound regulation can make the output sound become more pleasant and harmonious, unify a variety of tones, and can create a dramatic effect according to specific performances. Beautify, decorate the sound, can

Settings and control of professional stage sound system【一】

As for the professional stage sound setting, the modern stage uses the stage sound to enhance the dynamic stage while creating a time and space environment. On the stage, there are many screens and various lights to improve the flexibility and visual perception of the stage.

How to balance the reverberation signal in the stage sound system

If we balance the stage sound reverberation signal, we can get different types of mixing noise.For example, cut off the mixing noise of some low frequency, increase some high frequency, listen to it, is there a bright effect.And reduce the high-frequency signal in the mixing noise, the sound is much more dim.Many people prefer to implement brighter reverberation on shorter reverberation times, while dim reverberation is used on longer reverberation times, perhaps because bright high frequency si

The introduction of adjustable horizontal and vertical directivity of line array speaker system 【二】

Introduction of the line array speaker system adjustable horizontal and vertical directivity: for the ordinary speaker system, its characteristic is the directivity axis and the speaker are vertical relationship.The directivity of the speaker system is 360 degree circular (lower frequency).If you want to adjust the directivity Angle of the speaker system, you have to adjust the axis direction of the speaker, so it is more complicated.Especially for linear array sound systems.So in the current li

The introduction of adjustable horizontal and vertical directivity of line array speaker system 【一】

Introduction to the adjustable horizontal and vertical directivity of the line array speaker system: any sound source has certain directivity in a certain frequency range, and any speaker system also has directivity, directivity is due to the mutual interference of sound waves, directivity is good for the speaker system, also has disadvantages.The main reason why we use linear array sound system is to make full use of linear array sound system can produce low frequency directivity.The principle,
