Sound maintenance tips




many good audio products after a period of time of use and maintenance by professional enthusiasts, sound quality as after fermentation will become more honest, the longer the use of audio more interesting so what should we pay attention to when using audio

1. Pay attention to the test of the new machineMany people get excited when they buy a new stereo and try to plug it in.You should pay attention to the sound box is not connected to the amplifier, the test opportunity directly impact the amplifier circuit.Sound is a passive device, and all the energy comes from the output of the amplifier.If the power is turned on before the road is turned on, the amplifier will be guilty.The power amplifier suffers when starting up, and your ears will suffer when listening to music later.Therefore, it is important to check whether all devices are connected when starting up, and set the volume knob to the minimum before starting up the system.If the system emits an unusual sound, it is better to shut down or power off. Please ask professional staff for debugging. Generally, it is not recommended for players to start up their own diagnosis, or it will affect the hardware performance.

2. Try to use in a reasonable ambient temperatureSound use of the environment temperature should be controlled in - at least 10 ℃ to 40 ℃, environment temperature to avoid big fluctuations.Excessive temperature variation and the use of sound in extremely low and extremely high environment will cause irreversible damage to the sound system.

3. Pay attention to environmental humidityIn the environmental humidity, sound should be placed between 50% and 80% relative humidity.Too humid environment will cause premature failure of internal components, or internal and external rust.Note the voltage frequencyPower supply voltage and frequency need to be in line with local power, and the aging of the sound will be accelerated if the sound is kept under non-rated voltage and frequency power conditions for a long time.

5. Avoid excessive dust environment and excessive vibrationAcoustics besides what everybody knows to want to avoid sunshine point-blank and heavy outside, on the condition that puts a space acoustics wants above all avoid the environment with too much dust and shake environment.In sound systems, especially power amplifiers, are very sensitive to environmental dust.Due to the need for heat dissipation, there will be heat dissipation holes on each power amplifier. Excessive dust will not only close the heat dissipation hole to prevent heat dissipation, but also cause damage to specific circuits after entering the body.In addition to sound whether the amplifier or speakers, to leave enough space around, especially in the amplifier do not stack other equipment.

6. Pay attention to the switching sequence of equipmentThe audio is the same as the computer which has the same switching sequence of the equipment.In addition to the power amplifier, we also choose audio source devices such as the disc. In the process of starting several devices successively, we should pay special attention to the sequence of starting and shutting down.When starting up, you should first start up the front equipment such as audio source, and then open the amplifier.When shutting down, turn off the amplifier before turning off the front equipment.When shutting down, you should also turn the sound volume to the minimum, not only can reduce the impact of the switch machine on the sound, and the next time you will not scare yourself

.7. Pay attention to special materialsMany power amplifiers, such as yamaha dsp-z9, are equipped with a socket or two for other devices on the back. This socket is for special use, and cannot be used to connect other high-power equipment, such as iron and other household appliances.Whether it is the socket on the back of the amplifier or the plug of the amplifier itself, live unplugging during use will impact the system and damage the body and the speaker.8. Do not wipe with water when cleaningIt is not recommended to use water to clean the stereo.The case of acoustics equipment is also made of more metal material, and waterproof acoustics are few, because of this water can cause the erosion of outer casing, and the conductivity of water is not suitable to be used as cleaner.If you want to clean the body, do not use volatile solution type cleaner, such as gasoline, alcohol and so on, as far as possible soft cloth, reduce the body scratch.
