What are the details of professional audio equipment.Bar music sound

　　The sound quality function of professional audio equipment is definitely better than other audio. Professional audio manufacturers need to pay attention when using it. What matters need to be paid attention to when using it?

　　1. If the professional audio equipment works with a large input power for a long time, the voice coil may cause the speaker to burn out due to the temperature reaching more than one hundred degrees. Therefore, it is necessary to have an input electric power that can ensure the normal operation of the speaker for a long time, that is, the rated input power. This data will be given in the data of the equipment. The important thing is to strictly implement it in use. In the case of unsatisfactory sound reinforcement effect The configuration change should be considered first, rather than simply increasing the power.

　　2. If professional audio equipment is used improperly, it is easy to cause howling. In order to reduce the scattered sound and improve the clarity, try to point the effect area of the speaker in the direction of the audience's seat.

　　3. Multiple speakers are often used at the same time at work. When connecting them, be sure to pay attention to the polarity. All speakers should have the same polarity. If the connected speakers have different polarities, the sound output will interfere with each other, and it will sound like a bass. Insufficient, obvious dissonance.

　　4. The power between the amplifier and the professional audio equipment should be matched. The overall sound quality of the reproduced sound depends not only on the characteristics of the speakers, but also on the output and load characteristics of the amplifier. If the sound is not ideal, don't just think that there is a problem with the speaker, but first consider whether there is a problem with the amplifier system connected to it.

　　Safety points and precautions for the use of audio equipment

　　In various application fields of audio and lighting, safety has always been the focus of everyone's attention, although every safety accident has different reasons. But there is one thing in common, that is, the production side ignores the safety of the site, or does not do well in safety precautions.

　　For audio equipment operators, special attention should be paid to the operation details in the process of using the equipment!

　　1. When the power socket is connected, the live wire (L) and the neutral wire (N) are reversed.

　　2. Hurry up to connect or turn on the power without confirming that the power supply is normal.

　　3. Connect the power supply when the electrical switch is still on.

　　Relevant explanation: Many electrical appliances have fuses at the position of the live wire, and the reverse connection will cause the electrical appliances to be still charged after the fuse is broken. It is better to use double fuses and double pole switches, which can cut off the live wire and the neutral wire at the same time. The row socket is directly connected to the electrical equipment. After connecting the voltage stabilizer and other protective devices to ensure that there is no abnormality, each equipment can be connected in a closed state. It is necessary to pay attention to the good contact between the socket and the power supply. At least make sure that the power amplifier switch is turned off and the volume is at the lowest level before turning it on. Some power amplifiers with microphone input should turn down the volume of their microphones

　　Key points: The wiring is in accordance with standard specifications; first check the status of the equipment, and do not rush to turn it on.

　　4. The power cord is exposed where it is easy to be stepped on and kicked.

　　Fifth, the wiring is messy, and the signal line and the power line are too close.

　　6. Forget to confirm whether the wiring is correct and firm.

　　Relevant explanation: When connecting the power cord, it should be considered that it will be pulled. You should first do the work to make it not easy to be pulled, such as leaving some length instead of reluctantly extending it, avoiding pulling at an angle with a large force, and trying to Keep the thread flowing, avoiding slits and sharp corners; tangled thread will look bad, but tangled thread is not good either. Wires act like antennas when energized, and neatly rolled and parallel wires will interfere more with each other than if they are perpendicular to each other. In particular, the tangled signal and power lines are the worst; incorrect and unstable wiring is a taboo in professional applications, and reliable cables can greatly reduce the chance of work accidents.
