Most of the time, the use of professional audio system is not only according to the book can do well, now in practical application, often the complexity of the environment is far more than in the past, so the theoretical knowledge in the book needs to understand and use flexibly in order to do a good job in the correct use of professional audio system.

而音響調試工作就是在實踐中檢驗對錯，畢竟一個演出是很多臺前幕后人的心血，沒有調試好音響系統一旦在演出中出現問題，就會讓整場演出大打折扣。下面為大家介紹音響系統前期的調試方法，希望能幫到大家。

And professional audio debugging is to test right and wrong in practice. After all, a performance is the painstaking efforts of many people in front of and behind the stage. If there is no sound system debugging well, once there is a problem in the performance, the whole performance will be greatly reduced. The following is to introduce the debugging method of professional audio system in the early stage, hoping to help you.

1、音箱位置的擺放

1. Placement of speakers

舞臺主擴音箱朝臺前兩側擺放，分體式音箱中低音音箱在下，中音音箱于中間，高音音箱放在上，因為低音箱發聲方向性小，人體、桌、椅等物體吸收少。高音音箱方向性強，易被物體吸收。

The main amplifier of the stage is placed on both sides in front of the stage. In the split type speaker, the bass speaker is at the bottom, the midrange speaker is in the middle, and the treble speaker is placed on the top. Because the direction of the bass speaker is small, the body, table, chair and other objects absorb less. The tweeter has strong directivity and is easy to be absorbed by objects.

兩套音箱的輻射區盡量彼此相疊，以增 大立體聲聽音區。歌舞廳兩側的輔助擴聲音箱箱口偏向廳后區，以滿足后區觀眾聽音需要，使廳內聲場分布較均勻。不宜在廳后墻壁置音箱，要確保聲像統一，避免出現反饋。

The radiation areas of the two sets of speakers should overlap each other as far as possible to increase the stereo listening area. In order to meet the audience's listening needs in the back area, the mouth of the auxiliary sound reinforcement box on both sides of the song and dance hall is inclined to the back area of the hall, so that the sound field distribution in the hall is more uniform. It is not suitable to install a speaker on the wall behind the hall. It is necessary to ensure the unity of sound and image and avoid feedback.

2、音箱接線

2. Speaker wiring

音箱接線一定采用音箱線，每根應在200股以上。音箱線兩根顏色不同，連接音箱和功放輸出端子應嚴格區分，兩個聲道完全一致，決不能錯接，否則會導致音箱反相放聲，使聲場分布不均勻，放聲音質變壞。

Speaker wire must be used for speaker wiring, each wire should be more than 200 strands. The two speaker wires have different colors. The connection between the speaker and the output terminal of the power amplifier should be strictly distinguished. The two sound channels are completely the same and must not be wrongly connected. Otherwise, the speaker will be reversed, the sound field will be unevenly distributed and the sound quality will be deteriorated.

3、音響設備的連接

3. Connection of audio equipment

音響設備連接一定采用音頻電纜，電纜屏蔽線和芯線應牢固焊接，避免虛焊現象出現。注意各插頭的接線規則，不能任意顛倒，尤其卡儂插頭平衡連接，卡儂插頭與大二芯插頭做平衡非平衡轉換連接，應按規范進行。調音臺后接設備的前兩臺盡量采取平衡方式連接，以減少系統噪聲，提高抗干擾能力。常用連接中卡儂插頭的2腳與大二芯或大三芯插頭的芯連接。

Audio equipment must be connected with audio cable, cable shield wire and core wire should be firmly welded to avoid false welding. Pay attention to the wiring rules of each plug, and do not arbitrarily reverse, especially the balanced connection of the XLR plug. The balanced unbalanced conversion connection between the XLR plug and the large two core plug should be carried out according to the specification. In order to reduce the system noise and improve the anti-interference ability, the first two sets of equipment connected behind the mixer should be connected in a balanced way as far as possible. In the common connection, the 2-pin of the XLR plug is connected with the core of the big two core or big three core plug.

4、依照各種歌舞廳音響設備的連接圖接好調音臺、音源以及周邊設備。

4. Connect the mixer, sound source and peripheral equipment according to the connection diagram of sound equipment in various song and dance halls.

5、調音臺的輸入通道參量均衡提衰量處于0dB狀態，輸入推子和主控推子均處于低位置。

5. The balanced attenuation of the input channel parameters of the mixer is in the state of 0dB, and the input pusher and the main control pusher are in the low position.
