The channel EQ group adjustment of the mixer is an important part of the tuning process. In each input channel, the panning button is set and labeled with L or R. The function of this knob is that when it is turned to the L position, it means that all the signals of this channel are transmitted to the L output, and in the same way, when it is turned to R, it means that all the signals of this channel are transmitted to the R output.
After the gain adjustment is complete, the next step is to adjust the channel equalization. The order of adjustment usually starts with the bass section and then moves on to the midrange and treble sections. This is because only the basic tone of the sound can ensure that the sound is good multiple overtones.
Most mixers offer some sort of channel EQ, usually in the form of segmented EQ, which is reflected in the two knobs labeled "treble" and "bass" on the console. When these two knobs are adjusted, signals above and below the manufacturer's predetermined frequency are boosted or attenuated.
When adjusting the equalization, it is important to pay attention to the selection of frequency, the setting of the q value, and the increase of gain. Frequency selection refers to which frequencies need to be adjusted;The setting of the q value affects the width of the bandwidth;The increase or decrease in gain affects the volume of the signal in that band.
