After a lot of good audio products have been used and maintained by professional enthusiasts for a period of time, the sound quality will become more intense as fermented, and the longer the sound is, the more interesting it is. So what should we pay attention to when using the sound?
1, the new machine test machine should pay attention
When many people buy new audio, they can't help but feel excited and want to plug in the power. You should always pay attention to the circuit that directly impacts the amplifier when the speaker is not connected to the amplifier. The sound is a passive device, and all the energy comes from the output of the power amplifier. When this road is not connected, if it is powered on, the amplifier can be guilty. It is the power amplifier that is sinned at the time of booting. It is your ear to be guilty of listening to music later. Therefore, be sure to check whether all the devices are connected after booting. After confirming, turn the volume knob to the minimum to restart the system. If the system emits a strange sound, it is better to shut down the power, please professionally debug, generally do not recommend the player to start the diagnosis, otherwise it will affect the hardware performance.
2, try to use at a reasonable ambient temperature
The ambient temperature of the sound should be controlled at least between -10 ° C and 40 ° C. The temperature environment should avoid large fluctuations. Excessive temperature changes and the use of sound in extremely low altitude environments can cause irreversible damage to the sound system.
3, pay attention to the environmental humidity
In terms of environmental humidity, the sound should be placed between 50% and 80% relative humidity. An environment that is too humid can cause premature failure of components inside the machine or rust inside and outside the machine.
4, pay attention to the voltage frequency
The power supply voltage and frequency need to be consistent with the local power. For a long time, the sound works under the power condition of non-rated voltage and frequency, which will accelerate the aging of the sound. Â
5, to avoid excessive dust environment and excessive vibration
In addition to the sound that everyone knows to avoid direct sunlight and heavy pressure, the sound must first avoid the environment with excessive dust and vibration environment. In audio systems, especially power amplifiers are very sensitive to environmental dust. Because of the need to dissipate heat, there will be heat dissipation holes on each power amplifier. Excessive dust will not only block the heat dissipation of the heat dissipation holes, but also cause damage to the specific circuit after entering the inside of the machine. In addition, whether it is an amplifier or a speaker, there must be enough space around it, especially on the amplifier.
6, pay attention to the device switching sequence
The same sound as the computer has the same problem of the order of the devices. When using the audio, the source device should be activated first. Usually in addition to the amplifier, we will also choose the sound source equipment such as the disc player. In the process of starting several devices, we should pay special attention to the power-off sequence. When starting up, you should first start the front device such as the sound source such as the disc player, and then turn on the power amplifier; when shutting down, turn off the power amplifier and then turn off the front device. When the power is turned off, the volume of the audio should be adjusted to the minimum, which not only can reduce the impact on the sound when the machine is turned on, but also will not scare yourself when you turn on the next time.
7, pay attention to special purpose
Many amplifiers, such as the Yamaha DSP-Z9, will have one or two sockets for other devices. This socket must be dedicated to other high-power devices, such as irons and other household appliances. Whether it is the socket behind the amplifier or the amplifier's own plug, the plugging and unplugging during the use will impact the system and damage the body and the speaker.
8, clean, avoid rubbing with water
It is not recommended to wipe with water when cleaning the sound. The sound equipment casing is also made of metal, and the waterproof sound is very small, so water will cause erosion of the outer casing, and the conductivity of water is not suitable for use as a cleaning agent. If you want to clean the body, do not use volatile solution-type cleaners, such as gasoline, alcohol, etc., try to choose a soft cloth to reduce the scratch on the body.
