Home theater system, people tend to pay more attention to acoustic design, environmental design, audio and video systems, and so these big aspects, but in fact to a home theater system to maintain a good long-term state, always have a good effect, there are some small The details require our attention.

      Theater equipment for a long time do not have to go wet
Some people in order to save power, so the equipment will be used after the power cut off. This practice is true, but users living in the South need to pay attention. The southern region every rainy season, the weather is wet, and the humidity is too high is the natural enemies of audio and video equipment. Too much water in the air will penetrate into every part of the audio and video equipment, resulting in adverse effects. At this time, if you do not use the equipment for a long time, but also turn on the power, press the switch, let it work for some time, use the heat inside the machine to disperse the moisture.　　电源插正负极的处理

　　Many people may ignore the power plug in the positive and negative impact on the whole system, a set of positive and negative processing system is well structured, accurate and smooth positioning. The so-called power plug positive and negative is the exchange of the zero line and the correct access to FireWire equipment, that is, the absolute phase of the so-called equipment. If a system of equipment is not the same power phase, will make the sound of the high frequency is relatively fuzzy and low frequency bounce is relatively poor. Measure the positive and negative methods are: first to find out the socket used in the 0 line, the measured equipment wiring in addition to the power cord all pulled out, with a multimeter of the exchange file measuring equipment between the shell and power line 0 Voltage, write down the reading, and then plug the device into the socket, and then note the voltage between the chassis and 0 lines, take the low reading for the correct interpolation.

The influence of the arrangement of the wire on the sound quality

Some friends think that the wire as long as the connection can be, as the connector is not strong or how the wire is not fixed. This idea is wrong, if the wire ring, side by side, the direction of chaos will interfere with each other, there are noise, and even hum. In addition, if the connector is not strong, that connector prone to oxidation or dirty, the same will affect the sound quality.

Home theater design to local conditions

In the home theater design process is the most bogey from the reality, blindly imitate others, such as people with long signal line, short horn line effect is good, this is because the front and rear and the laser machine are balanced. If your equipment is not balanced, but also to imitate, it is difficult to achieve the same effect.
