The connection between the professional audio equipment and the power amplifier

Professional audio equipment need to connect the right to make the system play a good performance, but many people do not know the correct connection method of professional audio equipment and power amplifier and some techniques related, by the sound system caused by improper collocation play bad phenomena have occurred, it should pay attention to what matters in connection with the power box when the need to pay attention to? With the power line connection between the speaker and the power between each equipment matching, impedance matching, we do not go, talk between about speaker and power amplifier circuit connection.

1, pay attention to the power supply voltage: audio equipment must have the special power and standard, try to use the "power sequence controller", although the cost will increase and improve the system stability and ease of use, there is a special power supply, but also have the power socket, stable and reliable in short: correct connection of steady power all sound the equipment is very important. Another thing to note is that some power devices of imported equipment will have 110V and 220V selector switches. In China, we must confirm that 220V can be connected when power is selected.

2, pay attention to the length of the signal line: in connection with the equipment, we should try to use a shorter signal line as far as possible to save cost, second to reduce line resistance and interference. Under normal conditions, the longest signal line using the balanced transmission method can reach about 300 meters, while the non balanced line can not be used for long distance transmission. Try to use the balance line to line signal amplifier, if there are multiple power system, it is best to use a sufficient amount of signal amplification from distributor signal line, no attenuation of the supply of each power amplifier used alone, it can reduce system noise, reduce the risk and improve the signal-to-noise ratio.

3, the quality of the speaker line: try to use the relatively thick and short full copper special speaker line. When connecting, we must also pay attention to distinguish the positive and negative poles and avoid short circuits, especially the plugs of professional four cores or four core speakers. The number of the wiring terminals is very small, so we must pay attention to the wiring.

4, pay attention to the grounding of equipment: it is very important to connect all the sound equipment to the ground wire correctly. Good grounding can reduce the interference of the signal transmission and improve the stability of the equipment. Note that the ground wire should be in accordance with the lightning line grounding standards, is buried in the underground part of the conductor to rust and contact, to better buried deep, do not share the power line configuration and three-phase grounding line, that will not reduce the noise in the sound system, but also easy to damage the equipment.

5, pay attention to the signal's phase inversion and short circuit: signal line short circuit often cause silent fault. It's very troublesome to check up. Unless a signal line is removed and tested with multimeter, so the welding line must be careful.

This is about the wiring connection between speakers and power amplifiers. There are more details. There are more details. In the process of operation, we need to pay more attention. If we feel more trouble, we can find a professional company responsible. If you buy the professional sound equipment of crystal front audio manufacturer, you can worry about the pillow, professional manufacturers, let you rest assured.
