In the sound engineering, the role of sound can not be ignored, some large enterprises, institutions or entertainment venues need the cooperation of audio equipment, so pay attention to eight points in the process of debugging audio to avoid unnecessary trouble.
Eight key points in the audio debugging process
Key point 1: The first is the technical problem of the line connection, because the system communication noise that is common in the sound is the result of the process of the line connection is not completed, and the system balance connection must also be carried out according to the standard. Connection, of course, inferior connectors are also not used.
Point 2: The effect of the sound circuit processing needs to be improved. The reason is that the microphone is screamed after the post-fader signal is taken.
Point 3: The mixer is the control center of the entire sound system. Do not over-adjust the EQ of the mixer. Sometimes the high, medium and low EQ balance on the mixer is equally enhanced or attenuated, indicating that the system is not adjusted. Re-debug the system.
Point 4: The three spectral waveforms of the mountain type, the swallow type, and the wave type are the common frequency points of the equalizer. However, these images are indeed very vivid images, which are all imagined by the tuner, but actually This is not the case. If you only rely on human involvement, the results of the commissioning are of course counterproductive.
Point 5: The processing power of the bass signal needs to be improved. Obtaining the signal from the inappropriate position in the system will bring unnecessary trouble to the field control.
Point 6: The stronger the accompaniment sound, the weaker the vocals will make the singer feel at a loss. At this time, the necessary adjustments should be made to the compressor. Different brands of amplifiers and speakers are used together, so the distribution signal brings many problems, whether the impedance is matched, whether the level distribution is balanced, whether the power obtained by the speaker is normal, and it is difficult to adjust the frequency characteristics of the sound field and the speaker with one balance. .
Point 7: The sensitivity of the amplifier in the audio area requires special reference and debugging.
Point 8: Finally, the level of the sound system, the system must do a zero level adjustment.
In the sound engineering, we must pay attention to the above eight points. In fact, it is not responsible for careful observation. We must pay special attention to the installation and debugging process to make our audio reach the best state.
