Press the knob from top to bottom:
GAIN Note: (Gain adjustment, adjust the overall amplification of the initial input signal of the channel, it should not be too large, too large is easy to whistle)
HIGA treble (put mid position)
MID IF (put in the middle)
LOW low frequency (put mid position)
MON monitor control (adjusted according to the scene)
EFF effect (reverb, tuned to the scene)
PAN sound field (put the center position,)
The structure of the digital mixing console is not the same, and the parameter adjustment is in a special area. It is different from the analog station, but the tuning idea is the same, the picture refers to the title map.
The GAIN gain control knob (input level adjustment), in the mixer circuit, adjusts and sets the input signal to have a wide undistorted dynamic range and the best signal-to-noise ratio. GAIN provides a 40dB continuously adjustable gain range. When it is set to -40dB, the signal level is the lowest, that is, the input signal is attenuated by 40dB; when it is set to 0dB, the attenuation is 0, and the input signal is the strongest. When adjusting the GAIN knob, first turn the GAIN knob clockwise to the position where the peak indicator light just keeps on, then slowly turn it counterclockwise back to the position where the indicator light is off, and then go back to increase about 6dB, so that the indicator light is at the position where the indicator light is off. On the critical level line, which is lit when the signal peaks appear, so that you can be sure that the input signal has been adjusted to the proper level. In fixed use occasions, after the GAIN knob is adjusted once, generally do not turn it. Be careful not to use the GAIN knob for volume control, otherwise it is easy to overload the front-end circuit, destroy the normal working state of the audio system, and even damage the speakers.
The picture of the analog console is FX16, the most common mixer with effects.
HIGH high frequency
LOW band low frequency
The High, Middle, and Low three-band equalizer knobs can enhance or attenuate high frequency, middle frequency, and low frequency respectively, and the control range is plus or minus 15 decibels. The midrange control is especially useful when picking up vocals, and can be used to modify the performer’s voice very accurately.
Bass: 20 Hz ~ 500 Hz when appropriate, the bass is relaxed and the sound is plump and soft. When it is insufficient, the sound is thin, and when it is increased too much, it will make the sound dull, the brightness will decrease, and the nasal sound will be enhanced.
Midrange: 500 Hz ~ 2 KHz Clear and bright sound when appropriate. The sound is hazy when not enough, and produces a phone-like sound when too boosted.
Treble: 2 KHz ~ 8 KHz is the frequency that affects the layering of the sound. When it is insufficient, the penetrating power of the sound decreases, and when it is too strong, it will mask the recognition of language syllables, making the sibilance aggravated and the timbre hairy.
MON MONITOR: The supervisor listens to the volume knob, and the monitor control potentiometer on the channel takes out each signal and sends it directly through the monitor bus to the monitor amplifier output for the engineer to monitor, so as to control the level of each input signal entering the mixing circuit Proportion. The monitor controls are set after the GAIN and EQ controls. Any changes to the EQ controls will cause acoustic feedback, but the controls of the pan and channel level faders have no effect on monitoring.
EFF EFFECT: Effect knob, adjust this knob to determine the output level of this channel to the effector. This adjustment knob is provided on each channel of the mixer. When using, you can use the built-in reverb of the mixer, or you can use an external effect/reverb. When an external effect/reverb is connected, the built-in reverb is disconnected from the mixer circuit, and only the signal from the external effect/reverb is output to each input channel. When playing or recording a program, adjust the effect/reverb knob of each channel to determine whether the signal of each channel is added and how much effect/reverb volume needs to be added, and then the excitation signals sent from all channels are concentrated into one effect /Reverb bus, and then the bus will send these signals to the master effect/reverb amplifier for mixing amplification and master output.
PAN PANPOT: Panning knob, panning adjustment knob, it is used to adjust the stereo position of the channel signal between the left and right channels. By adjusting this potentiometer, the stereo image of the channel can be shifted left and right. If the knob is turned to the left, the position of the sound will gradually move to the left, otherwise it will move to the right. When the knob is placed in the center, the sound image will be in the center position.
The above is the key point. This is one of the channels in the mixer. These buttons are the most common ones, so be sure to remember them. The functions of each other channel are basically the same.

May I ask the meaning and function of AUX, EFX, BAL, LEVEL in the mixer?
AUS means auxiliary in the mixing console: it becomes auxiliary with the main channel
EFX means effect. It means that there are some effects behind your mixer. There are delay effects, inquiring effects, reverb effects, and percussion effects lights.
LEVEL means level, which is what we call the gear in life. The high-end and resistance of the car are very popular.
