Each system of professional audio engineering includes a large number of equipment types and quantities, and the use methods of various equipment and the working mode of the system are different. Therefore, the equipment debugging of the system is also different, but the types of projects are also very different. , If you want to introduce the equipment debugging methods of all types of projects one by one, it would be too long, so here we only explain the steps of equipment debugging for general types of projects.
The first is the preparation before debugging. The debugging of sound engineering is a work that requires not only 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 means to meet the design requirements, so Make adequate preparations before debugging.
These preparations include: preparing necessary instruments and tools, such as phase meter, noise generator, spectrum analyzer, sound pressure meter and multimeter required for professional audio debugging; preparing all engineering design and construction drawings; carefully reading all equipment installation And manuals, and prepare the manuals for important or special equipment for later use; what is needed is to make sure that there are no irrelevant personnel on site before commissioning to avoid interference with commissioning.
Secondly, check the installation and connection of the equipment in accordance with the design and layout requirements. Different from the construction steps of sound engineering, 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 in debugging The previous inspection is necessary; at the same time, during the inspection, 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.
The other is to 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 professional audio system include: the voltage range of all equipment should be set to the power supply voltage, and one gear as high 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; power amplifier Is the working status of stereo, parallel mono or bridge mono, the protection status is not set, the choice of input transformer, etc.; what is the frequency division method of the speaker, and where is the high-frequency attenuation; the mixer's Signal input attenuation situation, signal grouping situation; what is the gear selection of peripheral equipment, whether to bypass, whether to link, whether to activate, etc.
The setting of the lighting system includes: the setting of the working voltage and signal voltage of all equipment; the setting of the lamp type to be controlled in the specific control equipment; the setting of the signal encoding form in the digital signal transmission, and the address of the receiving device Coding setting; determination of the light path position of all lamps or actions on the dimmer, setting of the function keys on the scanner, etc.
