There are many kinds of audio equipment, and our audio engineer needs to adjust each audio equipment. The human operation faults we are talking about mainly occur during the performance, such as silence, staccato, feedback, noise and so on.
1. The channel level attenuation switch of the mixer: Some mixers add a level attenuation switch of about 20dB before the gain knob. When the CD and other audio sources are input from the high-impedance port, due to the high level, it may be It is appropriate to press this switch to attenuate the audio signal by 20dB.
2. Mixer gain adjustment: Some sound engineers don't know the importance of channel gain, so they adjust the knob randomly, sometimes turn off the gain knob, and even press the 20dB level attenuation switch at the same time, thinking about this time How small will the sound be?
3. Adjustment of mixer equalization group: As the name suggests, the mixer is mainly used to adjust the tone, and the adjustment of the tone mainly depends on the equalization group. It is very simple to say, it is nothing more than high school bass plus a few corresponding frequency selection knobs. Although the sound may not be very good under normal operation, there will be no performance accidents. However, some sound engineers sometimes turn the balance knob boldly. If the bass is increased too much, the burden on the entire power amplifier and speakers will be greatly increased, which may damage the equipment, and the sound will be easily distorted.
4. AUX adjustment of the mixer: Everyone AUX is mainly used to send signals to the effector. In a mixer, if we send the signal effector from AUX6, after the effector processing, if we output 2 signals to the mixer Channels 23-24 of the audio console, then do not turn on the AUX6 knob in the two channels 23-24 at this time, otherwise the signal will flow back to the effector after being processed by the effector just now.
5. Mixer pan: The pan knob is often regarded as an optional thing, but when we use the left or right output volume of the total output, we must pay attention to the pan. If you use the total output right output signal but the audio and image of the mixer channel are all hit to the left, it will cause a silent failure, which needs attention.
6. Mixer monitor and mute switch: Generally, the mixer monitor and mute switch are close together. Be sure to see clearly when operating. If you press the mute switch by mistake when pressing the monitor switch, it will also cause a silent failure.
