The correct connection speaker and amplifier can make the entire system play a greater performance. Many people do not know the correct connection method of professional audio and power amplifiers and some related tips. In the last issue, the line connection between speakers and amplifiers should pay attention What matters, let's discuss this matters that need to be paid attention to the power matching, power reserve matching, impedance matching, etc. of professional audio equipment.

First, power matching. The power configuration standard for speakers and amplifiers is: under certain impedance conditions, the power amplifier power should be greater than the speaker power. Generally, the amplifier is about 1.2-1.5 times the rated power of the speaker, and it should not be too large. In the dynamic occasion, it should be 1.5------ At about 2 times, refer to this standard for configuration. Since it can ensure that the amplifier works in ZUI, it can also protect the speaker and ensure the safety of the system. If the school is improper, speakers and amplifiers work in a stable state.

Second, power reserve matching. Compared with the power reserves required by electronic pipe amplifiers and transistor amplifiers. For transistor amplifier, the selection of power reserve volume should meet the standard of about 10 times the high-fidelity power. Civil-high-end power amplifier should be about 6-7 times, and generally it must be 3-4 times. The electronic power amplifier can be large and small than the above -mentioned ratio. In addition, in order to allow it to withstand the strong veins in the program signal, the impact of the strong pulse of the program signal is not damaged or distorted, the rated power nominal power selected speaker should be about three times the power of the manager theory calculation.

Third, impedance matching. It refers to the rated output impedance of the amplifier, which should be consistent with the rated impedance of the speaker. At present, the amplifier used in professional speaker systems is generally obstructive. Generally, the power amplifier is the most when working at 4Ω-8Ω. Some audiors like to push more than 2 speakers. At this time, pay attention to the impedance of the speaker. More The impedance of only speakers will be reduced when parallel. If it is lower than 2Ω, the amplifier is easily damaged at this time. This approximate short -circuit work method should be avoided.
