In various application areas of audio and light, safety issues have always been the focus of everyone's attention, although every safety incident has different causes. But one thing is common, that is, the producers have neglected the safety of the site, or they have not done enough in safety precautions. For audio equipment operators, pay special attention to the details of the operation during the use of the equipment! 1. When the power socket is connected, the fire wire (L) and the neutral wire (N) are reversed. 2. If the power supply is not confirmed, it will be rushed to power on or power on. Third, the electrical switch is also connected to the power supply. Relevant explanation: Many electrical appliances have fuses at the position of the fire line, and the reverse will cause the appliance to still be charged after the fuse is broken. It is best to use a double fuse and a double-knife switch to cut both the live and neutral wires. The row socket is connected directly to the power equipment. When the protection device such as the voltage regulator is connected to determine that there is no abnormality, the equipment can be connected in the closed state. Need to pay attention to the good contact between the plug and the power supply. At least check that the power amplifier switch is off and the volume position is at a minimum before turning it on. Some amplifiers with microphone input have to turn off their microphone volume. Key points: Wiring is in accordance with standard specifications; first look at the status of the equipment, do not rush to start. Fourth, the power cord is exposed to places that are easily stepped on. Fifth, the wiring is cluttered, the signal line and the power line are too close. 6. Forget to confirm that the wiring is correct and secure. Relevant explanation: When the power cord is connected, it should be considered that it will be pulled. It should be done first to make it difficult to be pulled. For example, leave some lengths and do not force it to extend, avoid pulling at the angle of force, try to pull Keep the line smooth, avoid the slits and sharp corners; the wires will not look like a bunch, but it is not good to use the wires in a group. When the wires are energized, they are like antennas, and the neatly rolled and parallel wires are more likely to interfere with each other when they are in close contact with each other. In particular, the tangled signal lines and power lines are the worst; improper wiring and instability are taboos in professional applications, and reliable wires can greatly reduce the chance of accidents. Key points: The role of the connection cannot be ignored. 7. There is no confirmation that each device has turned the volume to the minimum position. Eight, the boot sequence is wrong. For example, turn on the power amplifier first. Nine, the volume is too loud when debugging. Related explanation: If the volume is too large, there will be a large current surge, and the device may be killed in an instant. Although professional equipment has considerable protection, don't take risks. Equipment can sometimes be damaged before the protection circuit is activated. All three of these negligences and errors can burn audio equipment, especially speakers. Key points: Careful operation at all levels. X. In the attempt to move, change equipment. 11. When I was working, I forgot the status of the monitor. Twelve, when the equipment is working abnormally, don't calmly deal with it. Relevant explanation: Try not to move it while the equipment is working, and try to pause it when it is not moving. The state of the monitor material refers to whether there is any abnormality, mainly pay attention to whether the volume is overloaded. When you have an abnormality, you should calmly think about taking measures quickly and accurately.
