Most of the time, the use of professional stage sound system is not only according to the book said can be done well, now in the actual application, often the complexity of the environment is far more than before, so the theoretical knowledge on the book is needed to understand and flexibly use to do the correct use of professional sound system. And professional sound debugging work is to test the right and wrong in practice, after all, a performance is a lot of the effort of people in front and behind, no good debugging sound system once problems in the performance, will let the whole performance greatly reduced. Below for you to introduce the professional sound system debugging method, I hope to help you. The first is the preparation before commissioning: 

1. The placement of the speaker position: the main stage expansion speaker is placed on both sides of the stage, the split speaker is at the bottom, the medium speaker is in the middle, the soprano speaker is placed on the top, because the low speaker sound direction is small, the human body, table, chair and other objects are less absorbed. Treble speaker is directional, easy to be absorbed by the object. The radiation areas of the two sets of speakers are as stacked with each other as possible to increase the stereo listening area. The mouth of the auxiliary expanded sound box on both sides of the dance hall leans to the back area of the hall to meet the needs of the audience in the back area, so that the sound field in the hall is evenly distributed. Should not put a sound box in the wall behind the hall, to ensure a unified sound and image, to avoid feedback. 

2. Speaker wiring: speaker wiring must use speaker cable, each should be more than 200 shares. Speaker line two colors are different, connect speaker and power amplifier output terminal should be strictly distinguished, two sound channels are completely consistent, must not be wrong to connect, otherwise will lead to speaker reverse phase sound, make the sound field distribution is not uniform, sound quality becomes bad. 

3. Connection of the audio equipment: the audio cable must be used for the audio equipment connection, and the cable shielding wire and the core wire should be firmly welded to avoid the phenomenon of false welding. Pay attention to the wiring rules of each plug, can not be arbitrarily reversed, especially the balanced connection, Carnon plug and large two-core plug for the balance of non-equilibrium conversion connection, should be carried out according to the specifications. The first two units of the tuning station are connected as balanced as possible to reduce the system noise and improve the anti-interference ability.The 2 feet of the medium Canon plug connect to the high quality core of the large two or third core plug. 

4. Connect the tuning table, sound source and peripheral equipment according to the connection diagram of various sound equipment in the dance hall.
