Professional audio equipment and power amplifier connection matters

　　Professional audio equipment needs to be correctly connected to make the entire system play well, but many people do not know the correct connection method of professional audio equipment and power amplifier and some related tips. From time to time, what should be paid attention to when connecting speakers and amplifiers? Pay attention to the line connection between the speaker and the amplifier, the power matching between each equipment, impedance matching, etc. Line connection between speakers and amplifiers.

　　Professional audio equipment and power amplifier connection matters

　　1. Pay attention to the power supply: The audio equipment must have a dedicated power supply and standard voltage. Try to use the "power timer" as much as possible. Although the cost will increase, it will improve the stability and ease of use of the system. Reliable power sockets, in short: it is essential to correctly connect the power supply of all audio equipment. Another point should be noted: Some imported equipment power parts will have 110V and 220V selection switches. In my country, we must confirm that when choosing to choose at 220V positions, the power can be connected.

　　2. Pay attention to the length of the signal line: When connecting the device, try to use a shorter signal line as much as possible to save costs and reduce line resistance and interference. Under normal circumstances, the signal line with a balanced transmission method can be about 300 meters, and the balance line cannot be transmitted for a long distance. The amplifier's signal line should be used to use the balance line. If there are multiple amplifiers in the system, it is best to use the signal amplification allocation to distribute enough and no attenuation signal lines to provide each power amplifier separately. This can reduce the system noise noise. , Reduce hidden dangers and increase signal -to -noise ratio.

　　3. The quality of the speaker line: Try to use a relatively thick and short -copper -specific speaker line. You must also pay attention to distinguishing the positive and negative poles and avoiding short circuit when connecting. The column is very small, and you must pay attention when the wiring.

　　4. Pay attention to the grounding of the device: It is very important to correctly connect to all sound equipment to all audio equipment. Good grounding can reduce the interference of equipment signal transmission and improve the stability of the equipment. It should be noted that the ground wire should be done in accordance with the grounding standard of the lightning protection line, that is, the conductors buried in the underground part should prevent rust, contact well, and deep land. Not only will it not reduce the noise in the audio system, it is also easy to damage the device.

　　5. Pay attention to the anti -phase and short circuit of the signal: The short circuit of the signal line often causes silent failure, but it is very troublesome to check. Unless the signal line is removed by the universal meter, it is particularly careful when welding.
