With the popularity of audio equipment in film and television halls and the increase in users of film and television halls, many high-end equipment have successfully entered the lives of users in film and television halls. Audio, as the main equipment, is an indispensable part of the film and television hall system. Therefore, how to maintain the audio equipment of various movie halls has become a problem for us to discuss. In order to let users of the film and television hall enjoy their equipment bravely, Yiju Bianxiao made an inventory of some taboos in the use of audio equipment in the film and television hall, hoping to help the users of the film and television hall so as to extend the service life of the equipment.
Film and television hall sound
1. Pay attention to the sequence of switches
In the process of turning on and off the audio equipment of the film and television hall, the equipment will be impacted by electric current. If there is no reasonable switch, it will burn out and other damages over time, making our equipment disappear instantly.
The correct startup sequence: audio source equipment audio processor equipment (crossover, equalizer, effector, etc.). ) Power amplifier, TV projection, etc. The shutdown sequence is opposite to the startup sequence, which can protect the equipment from impact damage to a certain extent, develop a habit, and improve the service life of the audio equipment of the film and television hall.
2. Don’t twist and burn the wires
There are always users who tie all kinds of wires together for convenience, and they are tidying up their desks. However, when the AC current flows through the money, it is easy to damage the sound quality of the device. In addition, the signal cable and speaker cable cannot be wound around, which may cause other effects while affecting the sound quality.
3. The device cannot be stacked
Stacking equipment, as the name implies, is a stacking CD player, power amplifier, converter, etc. Equipment stacking will affect the vibration reduction to a certain extent, so that the laser machine and the power amplifier interfere with each other and affect the overall sound of the equipment.
During the placement process, the equipment can be placed on a special shelf or in a slightly larger space.
4. The microphone should be put away
Users who have installed a karaoke system at home should pay attention to the microphone being too close to the speaker, or pointing towards the speaker, which is likely to cause sound feedback and screaming. In severe cases, the high-pitched part of the speaker may be burned. So pay special attention to this. In addition, when using speakers, we must not only pay attention to the direction of the microphone, but also stay away from the magnetic field.
5. Pay attention to clean sound dead corners
As we all know, the cleaning of audio equipment in the film and television hall can not only improve the cleanliness, but also increase the service life of the audio to a certain extent. But when cleaning up, we often forget to clean up some dead corners, such as audio cable terminals.
After a period of time, the terminals of audio equipment in movie theaters are easily oxidized, and the oxidized hydrogenated film will affect the contact state of audio equipment, thereby reducing the sound quality of the equipment. Therefore, when cleaning, you can use detergent to clean the terminal contacts to ensure that the sound neck device always maintains a good connection.
