In the home theater system, people tend to pay more attention to the big aspects of acoustic design, environmental design, audio and video systems, etc., but in fact, a home theater system has to maintain a good state for a long time, always have a good effect, and some small The details need our constant attention.
Cinema equipment does not have to go wet for a long time
In order to save electricity, some people cut off the power after using the equipment. Although this is true, users living in the South need to pay attention. In the southern region, during the rainy season, the weather is humid, and the humidity is too high, which is the natural enemy of audio-visual equipment. Excessive moisture in the air can penetrate into every part of the audio-visual equipment, causing adverse effects. At this time, if you don't use the equipment for a long time, turn it on, press the switch, let it work for a while, use the heat inside the machine to disperse the moisture.
Power supply positive and negative pole processing
Many people may ignore the influence of the positive and negative poles of the power supply on the whole system. A set of positive and negative processing systems is well-defined, accurate and smooth. The so-called positive and negative of the power plug refers to the correct connection of the zero line and the live line of the AC, which is the absolute phase of the so-called equipment. If the equipment of a system is not in the same power phase, the high frequency of the sound will be blurred and the bounce of the low frequency will be poor. The main methods of measuring positive and negative are: firstly, find the 0 line of the socket used, and unplug all the wires of the tested equipment except the power cord. Use the multimeter's AC file to measure the housing between the equipment and the power supply 0 line. Voltage, write down the reading, then plug the power cord of the equipment into the socket, then write down the voltage between the chassis and the 0 line, and take the correct reading.
The effect of wire arrangement on sound quality
Some friends think that the wire can be connected as long as it is. It doesn't matter if the joint is not strong or the wire is placed. This kind of thinking is wrong. If the wire is looped, side by side, and the direction is disordered, it will interfere with each other, and there will be noise or even hum. In addition, if the joint is not strong, the joint is prone to oxidation or dirty, which also affects the sound quality.
Home theater design should be tailored to local conditions
In the home theater design process, the most taboo is not to start from the actual, blindly imitating others, such as people's home long signal line, short speaker line effect is good, because its front and rear and the laser are balanced. If your equipment is not balanced and you want to imitate it, it is difficult to achieve the same effect.
There are many different versions of DIN Connectors. The name of each type comes from the number of pins the connector has (3-pin DIN, 4-pin DIN, etc.) Some of these pin numbers come in different configurations, with the pins arranged differently from one configuration to the next.
DIN cable connector 3-pin, 4-pin, 5-pin, 6-pin, 7-pin, 8-pin degree 180, 216, 240, 262, 270
DIN cables, DIN connector, telephone cable, computer cable, audio cable
