很多时候音响系统的使用不是仅仅按照书上说的就能做好，现在的实际应用中，往往环境的复杂程度远远超过以往，因此书本上的理论知识是需要理解并灵活运用才能做好系统的正确使用。
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.
而音响调试工作就是在实践中检验对错，毕竟一个演出是很多台前幕后人的心血，没有调试好音响系统一旦在演出中出现问题，就会让整场演出大打折扣。下面为大家介绍音响系统前期的调试方法，希望能帮到大家。
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、音箱位置的摆放
1. Placement of speakers
舞台主扩音箱朝台前两侧摆放，分体式音箱中低音音箱在下，中音音箱于中间，高音音箱放在上，因为低音箱发声方向性小，人体、桌、椅等物体吸收少。高音音箱方向性强，易被物体吸收。
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.
两套音箱的辐射区尽量彼此相叠，以增 大立体声听音区。歌舞厅两侧的辅助扩声音箱箱口偏向厅后区，以满足后区观众听音需要，使厅内声场分布较均匀。不宜在厅后墙壁置音箱，要确保声像统一，避免出现反馈。
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、音箱接线
2. Speaker wiring
音箱接线一定采用音箱线，每根应在200股以上。音箱线两根颜色不同，连接音箱和功放输出端子应严格区分，两个声道完全一致，决不能错接，否则会导致音箱反相放声，使声场分布不均匀，放声音质变坏。
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、音响设备的连接
3. Connection of audio equipment
音响设备连接一定采用音频电缆，电缆屏蔽线和芯线应牢固焊接，避免虚焊现象出现。注意各插头的接线规则，不能任意颠倒，尤其卡侬插头平衡连接，卡侬插头与大二芯插头做平衡非平衡转换连接，应按规范进行。调音台后接设备的前两台尽量采取平衡方式连接，以减少系统噪声，提高抗干扰能力。常用连接中卡侬插头的2脚与大二芯或大叁芯插头的芯连接。
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、依照各种歌舞厅音响设备的连接图接好调音台、音源以及周边设备。
4. Connect the mixer, sound source and peripheral equipment according to the connection diagram of sound equipment in various song and dance halls.
5、调音台的输入通道参量均衡提衰量处于0诲叠状态，输入推子和主控推子均处于低位置。
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.
