(Phone orders: 159 + 3713 + 2363) Zhengzhou KTV professional audio monopoly, Henan monopoly of the public broadcasting system sound sound system speaker and reasonable power amplifier configuration in the field of professional sound reinforcement, audio equipment configuration is very elegant wherein the amplifier and speaker configuration is the most important, though, a number of speakers to use products that are recommended in the power amplifier with specific brands or models of the user, but there are limitations, because users are often faced with many types of amplifiers, no start. Henan stage audio amplifier, speaker amplifier monopoly price terms amplifier and speaker configuration Zhengzhou meeting involved a lot of brands such as amplifiers, power tube type selection and low sensitivity speaker amplifier which should configurations. The configuration of the amplifier and speaker, generally with experience designer, hobbies, listening habits and other relevant factors, it is difficult to find a unified standard. Henan stage audio amplifier, Zhengzhou conference speaker amplifier monopoly price responsible Liu Yongjie Tel: 159 + 3713 + 2363 to discuss QQ: 96 + 234 + 3035 Sometimes we encounter some users or designers to save money often to lower power speaker configuration amplifier, some users have for so-called "power reserve sufficient" give great power amplifier speaker configuration. Obviously, this is inappropriate. Importantly, this configuration will damage the device. In amplifier and speaker configuration, amplifier power is indeed crucial, that is, to determine the principles of amplifier power should be uniform. As we all know, after making room acoustics design, based on a series of calculations to determine the need for speaker power, and then determine the speaker power amplifier power, but exactly how the two optional power to achieve the best match it? Henan stage audio amplifier, speaker amplifier Zhengzhou monopoly price first meeting, in the human ear within the domain of 20Hz ~ 20kHz, really focused a lot of energy in the music signals are basically in the middle and low frequencies, but only the equivalent of high frequency energy, low frequency Energy 1/10. Therefore, the general speaker treble power loss is much lower than the woofer, in order to balance the high bass; and amplifier like a current modulator, under the control of its input audio signal, different size of the output current to the speaker, the size to make it happen different voices, impedance under certain conditions, to get a nominal power of 400W or 200W amplifier reaches several times the output is very easy, but the power amplifier distortion (THD) will greatly increase, this distortion is mainly produced in , the low frequency signal frequency harmonics, the greater the distortion, high frequency harmonic energy is greater, and these high-frequency distortion signal will enter the tweeter together with the high-frequency music signal, which is why the low-power amplifier push The reason big burn tweeter speakers will happen. The concept of many people, as long as power amplifier, it is possible to burn speakers. Although some amplifier without distortion instruction, but because the equipment configuration has inherent distortion there may be in use have occurred, this time distortion indication has lost its meaning. Moreover, due to the user's experience and the quality of the power amplifier distortion often easily overlooked audio amplifier stage in Henan, Zhengzhou conference speaker amplifier monopoly price responsible Liu Yongjie Tel: 159 + 3713 + 2363 to discuss QQ: 96 + 234 + 3035 Second, The power amplifier and speaker configuration and target loudness as well as the use of occasions there is a certain relationship. Under certain target loudness, should allow dynamic music signal on each equipment can be fully guaranteed, if too much power amplifier, the gain setting is very small, loudness has to meet the requirements, but this time the gain of the amplifier limits the the dynamic range of the signal. Therefore, the power amplifier is not too large; otherwise, since wasteful spending, will bring loudness and music can not be both dynamic and speaker overload trouble. Based on past experience, the general language, music, public address spaces and large dynamic disco and other places there is a difference. There are generally amplified signal fluctuations small place, no longer or will soon provide a great amp current to the speakers, the power amplifier should therefore requires powerful than the power of large dynamic public address spaces to be smaller; in addition, so-called "power reserve "For the speaker should be, it's worth noting that the amplifier selected must be decided by the speaker, we should not have," the concept of power reserve "is to configure the amplifier. In other words, at a certain target loudness, the speaker can be larger than the design value of some, to prepare for different uses, and the power amplifier should be strictly determined by the speakers, there is not much flexibility. Henan stage audio amplifier, Zhengzhou conference speaker amplifier monopoly price in short, specific criteria for allocating power amplifier and speaker should be: impedance under certain conditions, should be greater than the speaker power amplifier power, but not too much. Without distortion amplifier in the general application site should be about 1.2 to 1.5 times the rated power of the speaker; in the case of large dynamic should be about 1.5-2 times. Referring to the standard configuration, since the amplifier can be placed in the best condition to ensure that the work, but also to ensure the safety of the speaker, even for inexperienced operators, as long as not operating serious mistakes or pre-tuned peripherals properly, can make speaker and amplifier work in a stable state.
