Mixing the use of three-stage equalizer
One of the main functions of the mixer is to modify the sound, and now the mixer (except for high-grade) part of the tone almost without exception are three-stage equalizer: high frequency, intermediate frequency, low frequency three parameters equalizer , That is, treble frequency 10kHz or 12kHz, bass 80Hz or 100Hz.
IF is the parameter adjustable (sweep), for the IF sweep frequency parametric equalizer most people will use, know the frequency button at a certain frequency, and then use the above button to enhance or attenuation it wants. But the bass knob some careless sound division is also like a way to see the bass knob on the 80Hz or 100Hz that the channel came in the electric guitar what, that the frequency is not used to cut it to the left, see To the tweeter on the 1OkHz or 12kHz also the button to the left to spin that the channel is the electric bass can not, which is wrong, because it involves the understanding of the characteristics of the three equalizer, in general The intermediate frequency parametric equalizer is a high Q ＆#118alue, narrow band bandpass filter, which is a peak frequency characteristic curve, the band is very narrow, but the frequency can move left and right. With this sweep knob is used in conjunction with a lifting and decay knob, and treble and bass knob is a low Q ＆#118alue, wide band bandpass filter, its frequency curve is scaffolding, so the bass knob The target 80Hz refers to its center frequency, which is 80Hz as the center of a region, its upper limit may extend to 300Hz, and the lower limit may extend to 20Hz. The same is true for 10 kHz or 12 kHz, and its uptrend may reach 16 kHz, and the next extension may be 5 to 6 kHz, so it is extremely wrong to decay or increase it indiscriminately You are not a point of exfoliation, but a sound area. So sometimes the sound of the band is thin, but can not find the reason, then look at the equalizer on the bass button is in the excessive attenuation position, perhaps the problem is.
In addition to the equalizer there is a button related to the frequency, that is, in some mixer under the gain button will have a low-frequency cut button, which is actually a high-pass filter, the above generally marked the removal frequency is 75 ~ 80Hz, which Is that when the button is pressed when the frequency below 75Hz will be blocked in the outside. Then the low-frequency knob is not also play a role? Of course, still play a role, it is still more than 75Hz band to enhance the role.
In this three-stage equalizer is the most important role in the IF parametric equalizer, which is really a good thing, it can find the need to deal with the frequency band to make accurate compensation for the sound, in the high-end mixer will usually set two intermediate frequency Parametric equalizer, one is HIMID high frequency, its frequency range is 600Hz ~ 1OkHz, the other is LOMID low frequency its frequency range is 150 ~ 2400Hz, but unfortunately the general mixer only one, its frequency range is generally 200 ~ 6000Hz. Sometimes there is a situation where a singer's voice is relatively thin, which means that it needs to give about 250Hz of its mid-range to make his voice sound full, but at the same time his voice is not very bright, but also to his 2000Hz to give about to enhance the sound of his voice, then you will find an IF parameter equalizer will be the trade-off, is not enough, then there is no way to make the mixer more than an IF parameter? Yes, then if the tune The AUX and the fader button PRE are easy to handle, and the M-1008 mixer from the Lannge Ligner presses the PRE, and the AUX2 output is taken from the fader before the equalizer , Now as long as the singer from the channel directly from the PRE, from the AUX2 output socket to take out the signal, insert another channel, now there are two IF parameters equalizer for use. You can use the first channel of the IF parameter equalizer compensation 250Hz, and then another channel IF frequency equalizer to compensate for 2000Hz, of course, at this time the first channel of the volume fader without pushing, the sound from the second fader Sent out, you can also use the first fader to send the sound and the second road than the utility. In case of AUX2 before the fader is occupied by the band, you can also use the fader after the AUX1, AUX3 or AUX4, at this time to channel 1-based, first with channel 1 IF parameter equalizer compensation 2000Hz, this channel is The main channel, and then the other channel IF parameter equalizer to compensate for 250Hz, the tone slowly after the push, hear the singer's voice can be full. But pay attention to this time by the two faders to control the singer volume, and some inconvenience, of course, can also be a good balance between the two after the mixed group, so that you can use all the way faction fader. There are two IF parameters equalizer on the singer's tone for color is enough, if the mixer does not support the output AUX jack, is there a way to get two IF parameters equalizer?
If there is a direct output jack on the console DIRECTOUTPUT also line, the general mixer's direct output jack is taken from the equalizer after the fader, now as long as the singer channel from the direct output jack to take out a signal, insert another All the way channel, now there are two IF parameters equalizer for use.
In addition to the three-stage balance, what is the way in the mixer on the tone for the modification? That would use the INSERT jack inserted, we know that the socket is very useful, you can plug effect, pressure limiter, , Then the same we can insert a monaural 15 or even 31 equalizer to modify the singer's tone.
