Good equipment should be properly and reasonably linked together to give full play to its good performance. However, many people do not understand the matching technology of power amplifiers and speakers. Due to improper matching, the sound system will not work at all. What should we pay attention to when linking power amplifiers and speakers? Now we have Jazz Dragon Sound Factory to introduce to you.

1、 Line connection between amplifier and loudspeaker

1. Attention to power supply: audio equipment shall have special power supply and standard voltage, which shall be separated from the power supply of light. With a dedicated power supply, there should also be a stable and reliable power outlet. Try to use the "power sequencer". Although the cost is increased, the stability and ease of use are improved. In a word: It is very important to correctly and reliably connect the power supply of all audio equipment. One more thing to note: some imported equipment will have 110V and 220V selector switches for power supply. In China, it must be confirmed that the power supply can only be connected to the 220V position.

2. Pay attention to the length of signal lines: when connecting equipment, try to use shorter signal lines to save costs and reduce line resistance and interference. Under normal circumstances, the maximum length of signal lines using balanced transmission mode can be about 300 meters, while non balanced lines cannot be used for long-distance transmission. The signal line of the power amplifier shall be balanced as much as possible. If there are multiple power amplifiers in the system, it is better to use the signal amplifier distributor to separate enough signal lines without attenuation for each power amplifier to use separately, so as to reduce system noise, reduce hidden dangers and improve the signal to noise ratio.

3. The quality of the speaker wire: Try to use a thick and short all copper special speaker wire. When connecting, pay attention to distinguish the positive and negative poles and avoid short circuit. Especially for professional four core or above speaker plugs, several terminals inside are very small, so pay attention to wiring.

4. Attention to equipment grounding: it is very important to properly connect the ground wire to all audio equipment. Good grounding can reduce the interference of equipment signal transmission and improve the stability of equipment. It should be noted that the grounding wire should be made according to the grounding standard of the lightning conductor, that is, the conductors buried underground should be rust proof, well contacted, and deeply buried, and should not be shared with the grounding wire configured for the three-phase power line, which will not only not reduce the noise in the audio system, but also easily damage the equipment.

5. Pay attention to the reverse phase and short circuit of the signal: short circuit of the signal line often causes silent fault, but it is very troublesome to check, unless one signal line is removed and tested with a multimeter, so be careful when welding the lines.
