Factory Inspection Standard For Marine Products
With a real understanding of the use environment, we can ensure that every step of the product has been rigorously designed and rigorously tested in the real application environment. The real marine audio must pass the following strict tests before leaving the factory to prove that it can be used for a long time in the harsh marine environment.
1) Humidity and salt spray test
The real risks to electronics in high humidity marine environments are corrosion and mechanical failure. Marine electronics are exposed to salt spray and moisture, which can lead to overall failure even for a short period of time without good protection.
Therefore, there must be special instruments and venues to simulate the extreme marine environment. All products must be tested under these conditions before leaving the factory. Some products are even tested continuously for more than 500 hours, pushing the quality to the extreme.
2) Vibration and shock test
The purpose of vibration testing is to ensure that the product is suitable for jumping environments and violent shocks, and can survive bumps or violent storms without any physical damage or degradation, which is also critical to the life of electronic products.
True marine audio must be rigorously tested in a controlled environment to simulate these conditions before leaving the factory to ensure that each product has a qualified shock and vibration quality, not just for a season, but in the product. the entire life cycle.
3) High temperature and UV test
The harsh ocean climate is also reflected in the extreme temperature difference between day and night, seasons and strong ultraviolet radiation on the ocean.
As a marine entertainment system, its performance must withstand such a test and remain the same, without any physical changes.
Therefore, marine audio must be tested at working temperature (-5°C-55°C) and storage temperature (-20°C-70°C), as well as 200 hours of UVA (long-wave ultraviolet) and UVB (medium-wave ultraviolet) before leaving the factory ) test to ensure that the product still works well in extreme environments.
4) Interface protection (waterproof and dustproof) test
Waterproof certification is an important factor for whether a product meets the requirements of marine grade and product durability. Under normal circumstances, the waterproof level of marine audio can not be lower than IPX5.

What are stereo and surround soundCar owners often complain that after changing the speakers, they cannot hear surround sound in the car, or there is no stereoscopic effect. After further communication, you will find that many car enthusiasts have no basic concep
How is the tone of the tube amplifier formed? Many enthusiasts like the sound of tube amps (also called vacuum tube amplifiers): warm and mellow, not unpleasant, not shocking, and soothing. People call this taste the smell of bile. The author has been playing with tube amps for decades and has
What is stereo audio? What is the difference between mono and surround sound?Stereo audio has been the dominant format for analog or digital audio in the music industry for decades. It's a relatively simple format that does a good job of simulating the way we naturally hear the world around us, and
合并式胆机还需要再加一个前级吗?很多烧友都有这样的疑问。这里有三个因素,一是音源输出的讯号是否大?很多外国CD机输出讯号偏小,加台前级可以放大讯号。二是音箱的灵敏度,灵敏度在90dB以下的音箱,加台前级,声音的表现会更好。三是胆机的放大量,增益30dB的标准合并式胆机,对输入讯号的放大量约15倍左右。而增益为20dB的合并式胆机,放大量约10倍,略显不足,动态会有欠缺。如果你对声音有很高的要求,最好再添一台前级做配套,将合并功放作为后级用。前级可以增10倍放大量,两台机加起来增益可达40dB。这时候,后级会推得更轻松、声音密度高、细节丰富、瞬态更强,音响系统的表现就非常完美了。
The basic composition of the listening system and the selection of amplifiers and speakersBasic components of a listening systemFirst, let’s talk about the composition of a complete system. Simply put, it can basically consist of the following three parts:Audio source, amplifier, speakers.Sound sour
What is an AV amplifierThe A (audio) of the AV amplifier represents audio and sound, and the V (video) represents audio and image. Therefore, the AV amplifier is an audio-visual amplifier that combines audio and video signal processing. It emphasizes the atmo
About--Basic knowledge of power amplifiersThe working principle of the power amplifier is actually very simple. Intuitively, it amplifies various sound signals played by the audio source to push the speaker to produce sound. From a technical point of view, a power amplifier is like a current modulat
