When using the Mixing console, no matter it is simple, complex, high-grade and low-grade, if you want to give full play to its performance, you must master the skills and experience of using the Mixing console. Taboos to use the Mixing console mainly include: Do not press buttons and adjust various knobs randomly, do not adjust the channel gain knob randomly, do not use or use parametric tone controller randomly, do not pay attention to the audio image adjustment button, do not pay attention to the auxiliary output knob, do not pay attention to the cooperation between the shunt volume fader and the main output volume fader, do not turn off unused volume faders in time, and do not turn on the phantom power switch randomly, Below is a detailed introduction from Gedi Audio:
1. Avoid randomly pressing buttons and adjusting various knobs
Although the Mixing console is simple and complex, the number of channels (channels) varies. In cases where we are not familiar with the audio console or do not understand the on-site system connection and usage requirements, it is strictly prohibited to press buttons and adjust various knobs indiscriminately. As the core equipment of the audio system, different systems have different connections. When the system is debugged, the relevant knobs are already in working state. If we press and adjust them carelessly, their working state will be destroyed. The effect will be destroyed in the light, and the system equipment may be damaged in the heavy.
2. Avoid randomly adjusting the channel gain knob
Generally, each input channel of the Mixing console has a gain selection button (with non attenuation and attenuation of 20 dB) and a gain adjustment knob. The function of these two buttons is to control the size of the audio signal entering that channel. If the signal is too large, it will inevitably cause the input amplifier to enter a saturation state, causing serious distortion of the audio signal; If the signal is too small, it either makes the sound very light or reduces the signal-to-noise ratio, which affects the sound reinforcement effect. Do not randomly adjust the channel gain knob. The correct approach should be to select the gain selection button based on the type and size of the input signal. This button has two options. If pressed, the attenuation will be 20-30dB (depending on the Mixing console); If not pressed, there will be no attenuation. When we input a microphone type signal (usually a few millivolts in size), there is no need to press the attenuation button; When we input a line level signal (such as DVD, card holder, etc.), we must press the attenuation button. The second step is to adjust the gain adjustment knob again to ensure it is in the correct position. When the PEAK indicator light is very or constantly on, turn the knob counterclockwise by 5-10 ° (a scale mark)
3. Avoid indiscriminate use of parametric tone controllers
Generally, the Mixing console is equipped with 3 or 4 segment parametric tone controller, which is composed of 6 or 8 knobs. These knobs are divided into two categories: one is gain control, labeled with -10 to+10, and the other is frequency knobs, which can be increased or decreased according to on-site needs. The adjustment of these knobs requires a certain level of tuning experience. In cases where you are unfamiliar or lack tuning experience, remember not to adjust these knobs indiscriminately, especially the gain knob, which is generally at "0". But we must also oppose the use of parametric tone controllers in any case
4. Avoid not paying attention to the sound and image adjustment buttons
In each input channel of the Mixing console, the audio and image adjustment button PAN is set and marked with L or
