Professional conference audio

　　1. The first is the preparation before debugging

　　The debugging of professional conference audio engineering is a work that requires both technology and experience, but also serious and responsible spirit. When the design, selection, layout and construction meet the requirements, the debugging of equipment and systems is the basic means to meet the design requirements , So make full preparations before debugging. Prepare all engineering design and construction drawings. Read the installation and operating instructions of all equipment carefully, and prepare the operating instructions of important or special equipment for future use. Another thing to prepare is to ensure that there are no unrelated personnel at the site before the commissioning work starts to avoid interference with the commissioning work.

　　2. Check the installation and connection of the equipment according to the design and layout requirements

　　Different from the construction steps of the project, the thinking of checking the installation and connection of the system and equipment in the equipment debugging stage is based on the entire system. The purpose is to find problems, and it is easy to find problems, so before debugging The inspection is necessary. At the same time, during the inspection process, the construction personnel should be asked whether there are any remaining problems during the construction process, and they are sure that there is no problem with the power supply line and voltage.

　　3. Make corresponding settings for all devices

　　Because the composition of the equipment of each system is different, the working environment of the equipment is different, and the signal processing and transmission methods of each system are also different, the meaning of setting is to make the equipment work in a reasonable state, and make the cooperation between the equipment, Control has a good foundation. The settings of the audio system include: the voltage range of all equipment should be set to the supply voltage, and one level higher as possible. The signal transmission level value of the system should be set as consistent as possible to ensure that the signal transmission reference point is the same. The working state of the power amplifier is stereo, parallel mono or bridge mono, the protection state is not set, and the input transformer is selected. What is the frequency division method of the speaker, and where is the high-frequency attenuation position. The signal input attenuation of the mixer and the signal grouping situation. How to choose the gear of the peripheral equipment, whether to bypass, whether to link, whether to activate and so on.
