8 Frequently Asked Questions About Professional Audio Engineering

　　In the process of doing professional conference audio engineering construction for customers, there will always be various problems. For this reason, the editor specially summarizes some common problems and introduces them to you. The following are the specific contents:

　　1. Compressor adjustment problem

　　A common problem with compressor adjustment in professional audio engineering is that the compressor does not work at all or acts excessively and causes adverse effects. The former problem can still be used immediately after the occurrence of the latter problem, and the latter problem will seriously affect the operation of the sound engineering system.

　　2. Effect loop processing

　　The rear signal of the fader should be taken to avoid the microphone whistling scene caused by the out-of-control effect. If it is possible to return, it can occupy one channel, which makes it easier to adjust.

　　3. The problem of signal distribution

　　In the case of several sets of speakers in a professional audio engineering project, the signal is generally distributed to multiple power amplifiers and speakers through an equalizer. But at the same time, it also leads to the mixed use of power amplifiers and speakers of various brands, which may lead to various problems when distributing signals, such as whether the impedance is consistent, whether the level distribution is even, whether the power obtained by each group of speakers meets the standard, etc. It is difficult to adjust the sound field and the frequency characteristics of the speakers.

　　4. System level adjustment problem

　　The amp sensitivity control knob was not in place, followed by the sound system not performing a zero level adjustment. Sometimes the sound output of the mixer channel can be increased by a slight push up, which can affect the normal operation and fidelity of the sound system.
