Installation and connection method of bar lighting and sound equipment

　　1. Installation method of bar lighting and sound equipment

　　1. How to install bar lighting and sound equipment. First, pipeline embedding must first be embedding pipelines and hooks. This is to be started after the project is confirmed. The embedded pipelines are mainly in the unbuilt stage or the undecorated ground surface. If they are not embedded in time, it will easily affect the progress of the decoration project. At the same time, the outlet of the embedded pipeline must be paid attention to. It must be handled in collaboration with the decoration department, otherwise it may affect the beauty of the decoration due to improper handling.

　　2. Welding and installation of the scaffold should be carried out as far as possible with the decoration project, because it is inevitable to open some holes and damage the existing decorations during the construction, which requires the assistance of the decoration construction party to complete.

　　3. Cable laying Cable laying is the easiest process and must be carried out carefully. To lay cables, you must master reasonable methods. For example, when threading the pipe, the steel wire and the cable to be worn should be bundled firmly, the head should be tied to reduce the resistance, and a small amount of lubricating oil should be applied if necessary.

　　4. Installation procedure The installation procedure of the equipment---open the box to check the integrity of the lighting and audio equipment to see if there is a lack of quantity. Install and debug the equipment one by one. Hang and place the speakers at the same time. The mixing console and cabinet can be placed in a small room, and the small room should be where the layout of the entire space can be viewed.

　　5. After the equipment is installed and debugged, all equipment should be inspected for the last time to see if there is any slack or unstable. Finally, perform final debugging on all equipment, and then call the customer for acceptance after confirming that there is no problem.

　　Second, the link points of bar lighting and sound equipment

　　1. The connection sequence of the bass sound system equipment: mixer (1-2 grouping) → equalizer → crossover → compressor → bass amplifier → bass speaker.

　　2. Auxiliary audio system equipment connection sequence: mixer (3-4 grouping) → equalizer → delayer (optional) → compressor → auxiliary speaker amplifier → auxiliary speaker.

　　3. Main audio equipment connection sequence: mixer (L-R main channel) → equalizer → exciter (optional) → feedback suppressor (optional) → compressor → main speaker amplifier → main speaker.

　　4. The connection sequence of the monitor audio system equipment: mixer (AUX output) → equalizer → compressor → monitor speaker amplifier → monitor speaker.

　　The role of bar lighting and sound equipment link

　　The first connection method can individually control the volume of the bass, so that the volume of the 1-2 group of the mixer can be turned up when we are shaking slowly or digo, and it can be turned down when the singer is singing, which is very flexible;

　　The second connection method can also control the sound of auxiliary speakers well;

　　The third type of main speaker is of course we are used to output the volume from the L-R total output of the mixer;

　　The fourth type of monitoring system, the standard is to output the volume from AUX, so that the volume of each channel of the mixer can be flexibly adjusted according to the requirements of the singer or the band, but in a smaller sound system, the monitoring signal can be directly from The main channel signal is taken.

　　Pay attention to the above ① and the second connection method: Since ①-②, ③-④ are grouped, we have independently output the signal to the bass system and auxiliary system from the corresponding output port at the back, then ①-②, ③- ④For grouping, don't use the mixer's total volume output anymore, that is, don't turn on the switch from ①-②, ③-④ to the mixer's total volume.

　　Of course, we still have to flexibly arrange the order of equipment connection according to the needs and the number of equipment. The above order is for reference only.

　　How to achieve the desired effect of stage sound

　　The professional lighting and sound on the stage is one of the art modeling techniques. The use of stage audio and lighting equipment and technical techniques, along with the development of the plot, as well as its light and color and change the environment, enhance the atmosphere, and highlight the core elements. To a large extent, it can also invent a sense of space and time on the stage. Shaped the external image of the stage performance, and provided the necessary lighting effects and so on. The following editor will introduce to you the setting function of stage professional audio.

　　When it comes to stage professional lighting and sound, it is also important to note that lighting is an important part of the performance space. Later, according to the development of the plot, the characters and the required specific scenes will be able to carry out a full range of visual environment lighting planning. Next, we must also pay attention to the artistic creation that should purposefully reproduce the planning purpose to the audience in a visual image.

　　The role of stage professional lighting and sound in modern performances, first and foremost, is to achieve lighting performances, so that the audience can see the artist's performance and the image of the scenery; help the audience's vision; shape the image of the character, set off the emotion and show the stage illusion; Invent the space environment required in the play; set off the atmosphere in the play; when the light and sound show the transformation of time and space, highlight the contradiction of the drama and strengthen the rhythm of the stage, which is rich in artistic appeal.

　　Stage sound sometimes cooperates with stage stunts. In modern performances, the intensity, color, distribution of lighting areas, and movement of lights all have greater plasticity and controllability.

　　The artistic effect of professional lighting of stage audio will be displayed with the progress of the performance and the continuous change of atmosphere. And when it comes to the application of stage professional lighting and sound, we must pay attention to the balance and nature of the sound quality is the goal we seek. The sky high pitch of the rotating wood horn, the most true to pure audio exhibition Show, transparent and clear, not sharp. The sound can be more detailed and accurate when processing the sound.
