Do not underestimate the construction of professional audio engineering, any set of high-quality professional audio system, can not do without the hard work of professional audio engineering staff, whether it is the placement of professional audio , or tuning. In the construction of the project, we will always encounter such problems or such problems. For these problems, the following points are summarized and I hope to help you. 1. System level problem: In the professional audio project, for the level problem, first check whether the sensitivity of the amplifier is lacking, and then check if there is any zero level adjustment in the system. Because sometimes a little bit of output is pushed through the console channel, a large output is produced, which in this case directly affects the dynamics and distortion of the system. 2, line connection technology: is a common system, the communication interference is loud, most of the cases are caused by the line connection technology is not done, for the balance conversion imbalance in the system, or the imbalance conversion balance Connections are usually connected according to specifications. 3, the problem of signal distribution: If there are several sets of speakers in the sound field, using an equalizer to distribute the signal, it is easy to bring a lot of trouble to the process of distributing the signal, because the impedance is matched or not, the equilibrium of the evaluation and distribution No, it is difficult to use the frequency and sound field of each speaker on an equalizer. 4, the action loop disposal: For this case, the processing method can take the post-signal of the fader, which can effectively prevent the microphone from whistling. If it is back, it can occupy one channel, which is convenient for debugging. 5, the frequency adjustment of the graphic equalizer in professional audio engineering: frequency point problem We have three spectral wave patterns, such as swallow type, mountain type and wave type, but the sound field is not required in actual application. Waveform, because the sound field frequency characteristic curve is generally relatively flat, if it is adjusted to the sound field frequency characteristic curve, it will cause the opposite effect. 6, low-voice signal disposal: not only need to choose the appropriate signal acquisition location, but also need to set the power of the amplifier. Avoid burning and other conditions. 7, the limiter adjustment problem: the common method has the problem that the excessive laying of the foundation will not only cause a reaction, but also cause the sound can not produce sound. 8. Manipulation problem: The mixer in professional audio engineering is the control center of the system. If there is a high, medium and low EQ balance on the mixer, it will be promoted equally or greatly, and the demand for this problem can be debugged from scratch. But don't overshoot the mixer's EQ. The above is a summary of the small problems that often appear in professional audio engineering. For these problems, I hope to attract everyone's attention.
