First, choose the shop for package installation

Users who understand the circuit can operate according to the steps in the manual. If users do not understand the circuit, they must contact professional personnel for installation. Do not disassemble them by yourself to avoid accidents. Therefore, users should choose the store where the package is installed as much as possible when purchasing audio equipment.

Second, check whether the product is qualified

There are so many fake and shoddy products on the market now that users must distinguish clearly when purchasing to avoid affecting the use of users. Some cheap equipment looks relatively new, but they do not know that the equipment parts inside have been damaged, and the circuit design does not meet the standards. This kind of equipment is easy to cause accidents in the use process. Therefore, the leased technicians suggest going to the regular stores to buy audio equipment.

Third, look at the sound quality

When selecting audio equipment, users do not have to choose a good brand. Famous brand products are also divided into three grades: high, middle and low. Brands that should not be bought by users represent good sound effects. For the sound that can withstand inferior levels, they may not be as good as those small brands with low brand awareness. Therefore, the technicians of Shanghai Lighting and Audio Rental suggest that the user must debug the sound when purchasing the sound to test the sound quality effect.

How to quickly and efficiently eliminate the noise in professional performance sound system

As we all know, in the stage performance, live sound reinforcement and other sound systems, the noise problem is a common and very troublesome problem. The noise generated by a set of audio systems may come from different aspects. The sound engineer should analyze, judge and deal with more complex situations separately. General noise may come from three aspects: first, improper connection of equipment; second, inherent noise of equipment; third, interference noise of power supply.
