Maintenance of line array main speakers mainly includes the following aspects:
Regular cleaning: Clean the surface and interior of the speaker regularly to prevent dust and dirt from affecting the sound quality. You can use a soft dry cloth to wipe the surface of the speaker, and avoid using a wet cloth or chemical cleaners. For internal cleaning, you can use a compressed air can or the cold wind of a hair dryer to blow away the dust inside the device, but be careful not to touch the speaker cone to avoid damage.
Moisture-proof measures: Keep the audio system away from water sources and humid environments to prevent equipment from getting damp and causing malfunctions. A humid environment can cause the diaphragm of the speaker to physically deteriorate, and the cone to get damp and moldy, resulting in weak sound playback.
Temperature and humidity control: Audio equipment should be placed in an environment with suitable temperature (generally 18℃-28℃) and moderate humidity (40%-60%). Avoid placing the equipment in direct sunlight, near heat sources or in humid places to prevent damage to the internal components of the equipment.
Dust prevention and ventilation: Keep the environment around the device clean to reduce the chance of dust entering the device. Ensure that the device has good ventilation conditions, avoid working in a closed, stuffy environment, and prevent equipment failure due to overheating.
Power management: Ensure that the power supply voltage used by the audio system is stable. It is best to use a power socket or power sequencer with a voltage stabilization function. Follow the correct power on and off sequence, turn on the audio source device first, then the processing device, and finally the amplifier and speaker; the opposite is true when shutting down to avoid damage to the device caused by the instantaneous current shock of powering on and off.
Cable inspection: Regularly check the appearance of audio cables, power cables, etc. to see if there are any damage, breakage, peeling, etc. Check whether the interface of the cable is loose, oxidized or corroded to ensure that the interface is in good contact and the signal transmission is stable.
Avoid collision and vibration: Speakers are fragile electronic devices and should be avoided from collision, squeezing and vibration to avoid damage.
