Have you mastered the secret to Dongguan audio maintenance?

Many high-quality audio products become more profound in sound quality over time, much like a wine that ages well. The longer a sound system is used, the more enjoyable it becomes. So, what should we pay attention to when using audio equipment? Here's an overview:

1. Be cautious during the trial run of the new machine.

Many people can't help but get excited when they purchase new audio equipment and want to plug it in right away for a test. But please be cautious not to directly connect the speakers to the amplifier's circuitry without properly hooking them up first. Audio equipment is a passive device, with all its energy coming from the amplifier's output. If you power on and connect it before this connection is made, the amplifier might suffer the consequences.

During startup, the amplifier takes the brunt, but it's your ears that will suffer while listening to music. Therefore, it is crucial to check all equipment connections before turning on, then turn down the volume before starting the system. If the system emits unusual sounds, it's best to shut it down and unplug it, and have a professional perform the tuning. Generally, it's not recommended for players to diagnose startup issues themselves, as it may affect hardware performance.

2. Use the product within a reasonable environmental temperature range.

The ambient temperature for audio equipment usage should be maintained between -10℃ and 40℃, with efforts to minimize temperature fluctuations. Excessive temperature changes, as well as operation in either too low or too high temperatures, can cause irreversible damage to the audio system.

3. Pay attention to environmental humidity.

In terms of environmental humidity, excessively damp conditions can lead to premature failure of internal components or rusting both inside and outside the machine.

4. Be mindful of voltage frequency.

Power voltage and frequency must match the local electrical supply. Operating audio equipment for extended periods under voltages and frequencies not specified can accelerate its aging.

Avoid excessive dust and excessive vibration conditions.

Sound systems, besides avoiding direct sunlight and heavy pressure as commonly known, should also be placed in environments with minimal dust and vibration. In the sound system, especially the amplifier, is highly sensitive to environmental dust.

Each amplifier requires ventilation holes for cooling purposes. Excessive dust can not only block the ventilation holes and hinder heat dissipation but also cause damage to the internal circuitry. Moreover, when it comes to audio equipment, whether amplifiers or speakers, adequate space should be left around them, especially avoid stacking other devices on top of amplifiers.

6. Pay attention to the sequence of equipment on/off.

Sound systems, like computers, also have an issue with the order of equipment shutdown. When using a sound system, the signal source device should be powered on first. Typically, in addition to the amplifier, we also choose devices like CD players as audio sources. During the process of sequentially turning on and off several devices, we should pay special attention to the order of shutdown.

When turning on the system, start with the source devices like a CD player first, followed by the amplifier; when turning off, do the opposite, turn off the amplifier before the source devices. Additionally, lower the volume of the speakers when shutting down to not only reduce the impact on the speakers during power cycles but also to avoid startling yourself when you turn it on next.

7. Avoid using water to clean

It is not recommended to use water to clean audio equipment. The casings of audio devices are often made of metal, and waterproof models are rare, so water can cause erosion to the casings.
