How to use the equalizer on the mixer flexibly One of the main functions of the mixer is to modify the timbre, and the tone part of the current mixer (except high-end) is almost a three-stage equalizer: high frequency, low frequency plus an intermediate frequency parametric equalizer , That is, high frequency lOkHz or 2kHz, bass 80Hz or 100Hz, some are marked with English HI and LO for you to guess, but you guess the above parameters will also be inseparable. The intermediate frequency is parameter-adjustable. For the intermediate frequency parametric equalizer, most people will use it. Know that you can use the frequency button to align to a certain frequency, and then use the button above to enhance or attenuate. However, the caretaker who is careless about the high and low knobs can be made in the same way. When I see 80Hz or 100Hz on the bass knob, I think that this channel is coming in electric guitar or something. Go to the 10kHz or 12kHz on the tweeter button and turn the button to the left to think that this channel is an electric bass. This is a big mistake, because it involves understanding the characteristics of the three-band equalizer. The IF parametric equalizer on the mixer is a high-Q, narrow-band band-pass filter. It is a peak-frequency characteristic curve. The frequency band is very narrow, but the frequency can move left and right. Used with this sweep knob is a boost and attenuation knob, while the treble and bass knobs are a low-Q, wide-band band-pass filter, and its frequency curve is a scaffold, so the bass knob The target 80Hz refers to its center frequency, which is a section centered at 80Hz, and its upper limit may extend to 300Hz, while the lower limit may extend to 20Hz. The same is true of the treble knob. 10kHz or 12kHz is also its center frequency point. Its upper extension may reach 16kHz, and its lower extension may be 5 ~ 6kHz, so it is extremely wrong to attenuate or increase it without distinction. What you destroyed is not a point, but a sound zone. So sometimes I feel that the mid-band of the sound is thin, but I can't find the reason. Then see if the bass button on the equalizer is in the excessive attenuation position, maybe the problem is. In addition to the equalizer, there is a button related to the frequency, that is, there will be a low-frequency cut button under the gain button on some mixers. This is actually a high-pass filter. The cut frequency is generally indicated to be 75 ~ 80Hz. It means that when the button is pressed, the frequency below 75Hz will be blocked out. So is the low frequency knob still functioning at this time? Of course it is still working, it still has a boosting effect on the frequency band above 75Hz. Among the three-band equalizers, the most important is the intermediate frequency parametric equalizer. This is really a good thing. It can find the frequency band to be processed and make accurate compensation for the timbre. Two high-frequency mixers are usually set on the high-end mixer. Parametric equalizer, one is HIMID high and intermediate frequency, its frequency range is 600Hz ~ 10kHz, the other is LOMID low and intermediate frequency, its frequency range is 150 ~ 2400Hz, but unfortunately there is only one general mixer, its frequency range is generally 200 ~ 6000Hz. Sometimes there is a situation where a singer ’s voice is relatively thin, which means that its mid-frequency of about 250Hz needs to be improved to make his voice sound fuller, but at the same time his voice is not very bright, and it needs to be addressed to him. The boost around 2000Hz makes his sound brighter. At this time, you will find that an intermediate frequency parametric equalizer will lose its balance, and it is not enough at all. Is there a way to make your mixer have an additional intermediate frequency parameter? Yes, if you have a direct output jack DIRECTOUTPUT on your mixer, it ’s easy to handle. Generally, the direct output jack of the mixer is taken from the fader after the equalizer. Now you only need to go from the singer channel. Take a signal directly from the output jack and plug it into another channel. Now you have two IF parametric equalizers for you to use. You can use the parametric equalizer of the first channel to compensate for 250Hz, and then use the parametric equalizer of another channel to compensate for 2000Hz, of course, the volume fader of the first channel does not need to be pushed up, and the sound is sent from the second fader , You can also use the first fader to send the sound to compare with the second, of course, if you are interested, you can use this analogy to get more IF equalizer, you can make more modifications to the sound, but there are Two IF parametric equalizers are enough to polish the singer's tone. In case your mixer does not have a direct output jack, is there a way to get two IF parametric equalizers? However, it should be noted that two faders are used to control the singer's volume at this time, which is inconvenient. Of course, you can also mix the two groups after the two volumes are balanced. In addition to the three-band equalization, is there any way to modify the sound on the mixer? Then we need to use the INSERT jack. We know that this jack is very useful. You can insert the effector, compressor, and exciter. Then we can also insert a mono 15-band or even 31-band equalizer here. How to modify the singer's tone? You can adjust the timbre as you like, but remember: the transitional modification can sometimes be self-defeating, but it can make the timbre very unpleasant. Here is just another way to modify the timbre. In addition, the 31-band equalizer is generally used in the main channel. In fact, the singer's tone can also be modified here. For example, after your channel equalizer compensates the singer's 2500Hz, it can be equalized in 31-band equalizer. Some improvements in the frequency band of 200 ~ 300Hz of the device can also achieve the effect of compensating human voice. It can be seen that being familiar with and making full use of the various jacks of the mixer can improve the grade of your mixer, obtain more sound processing methods, and make you work more handy.

You can still, you can take one signal from the auxiliary output of the singer channel, AUX, and then return to another channel. Similarly, you can also get two IF parametric equalizers. This auxiliary output is best used before AUX1, that is, the fader. This fader can send the processed signal to another route without being pushed up. If the AUXl before your fader is occupied by the band, you can also use the AUX2 or AUX3 after the fader. To use channel 1 as the main channel, first use channel 1 ’s IF parametric equalizer to compensate for 2500Hz, this channel as the main tone, and then use another channel ’s IF parametric equalizer to compensate for 250Hz, and slowly push up the tone after modification. The tone becomes full.
