How to use the mixing console equalizer
Click:1660 [Print] [Close]
Mixer is one of the most important role was modified on the sound, but now the mixing console (except high) tones are part of three-stage equalizer almost without exception: high-frequency, low frequency combined with a parametric equalizer that the treble frequency lOkHz or 2kHz, bass 80 Hz or 100 Hz, some are marked in English of the HI and LO let you guess, but do you think will be very near the above parameters. IF is the adjustable parameters, the parametric equalizer for the frequency will be used generally, that button aligned with the frequency of a frequency, then use the button above to boost or cut it wants.
But some careless high bass knob also like audio division law cook, to see the bass knob on the 80Hz or 100 Hz that this channel is the electric guitar come in something, that this frequency is to the left to cut out useless Bian Jiang, button to see the treble on lOkHz or 12kHz will toggle to the left of the rotation to think that this channel can do the electric bass, which a big mistake, because it involves the characteristics of the three band equalizer understanding of the IF tuning stage, the general parametric equalizer is a high-Q, narrow band bandpass filter, which is a peak frequency characteristic curve of a narrow band, but the frequency can move around.
Used in conjunction with the sweep knob is a knob to enhance and decay, while the treble and bass knob is a low-Q and wideband bandpass filter, its frequency is a scaffold-like curve, so the bass knob 80Hz is the subject of its center frequency, which is 80Hz for the center of a region, its upper limit may be extended to 300 Hz, while the lower limit may be extended to 20Hz. The same is true treble knob, 10kHz or 12kHz is also its center frequency, it may reach the upper extension of 16kHz, the next extension may be 5 ~ 6kHz, so I do not indiscriminate Tone decay or increase it is extremely wrong
You burn out because it was not a point, but a pitch. So sometimes feel weak voice in the band, but can not find the reason, then take a look at the bass EQ knob is in position over attenuation, perhaps is the problem.
In addition there is a button external equalizer with frequency, that is, the gain in the number of tuning button next stage will be a low cut button, which is in fact a high pass filter, generally indicated above, the frequency of removal is 75 ~ 80Hz, This means that when the button by going down below 75Hz frequency will be kept outside. Then the low-frequency knob is not yet time work? Of course, at work, it 75Hz still improve over the role of band.
In this three-band equalizer is the biggest IF in the role of parametric EQ, which is really good stuff, it can identify the need to deal with the band on an accurate tone compensation, generally in the high-end mixing console will set the two IF parametric equalizer, one is HI MID high frequency, its frequency range is 600Hz ~ lOkHz, the other is the LO MID low-IF frequency range it is 150 ~ 2400 Hz, unfortunate that only one mixer, and its frequency range is generally 200 ~ 6000Hz.
Sometimes this kind of situation: a singer's voice was weaker, which means about its frequency 250Hz to raise his voice to sound more full, but while his voice is not very bright, but also the need for his about 2000 Hz to enhance the bright voice make him more during this time will find a frequency parametric equalizer will be a loss, just not enough, it is not a way to make your mixer a multi-frequency parameter? Yes, then if your mixer has a direct output jacks DIRECTOUTPUT easily handled, and
General mixing console is the direct output jack from the equalizer after the pre-fader, now you need to access directly from the singer took out a signal output jack, insert another way channel, and now you have two IF parametric equalizer for you to use.
You can use the first channel parametric equalizer compensation 250Hz, and then use another channel parametric equalizer to compensate for 2000 Hz, of course, the first channel at this time do not push the volume fader, the sound sent out from the second Way Fader You can also send voice with the first road fader for the second road than utility, of course, if you are interested, you can so on, to get more frequency equalizer, you can do more modification on the sound, but there are two a frequency parametric equalizer for embellishment on the singer's sound has been sufficient, if your mixer has no direct output jack, is not there way to get two parametric equalizer IF it?
50Hz, the sound slowly modified push on, to hear the singer's sound can become full.
Still, you can access from the singer AUX auxiliary output that signals the way out and then back to another road access, as you can get two IF parametric equalizer, the auxiliary outputs AUX1 that is best for pre-fader, so that The Road fader without pushing up the signal can be treated to another way to deal with, if your pre-fader AUXl was occupied band, you can also use the fader or post-AUX2 AUX3, this time to mainly to channel 1, first IF channel 1 parametric equalizer compensation 2500Hz, this channel-based sound, and then another channel parametric equalizer to compensate for IF 2
But note at this time by two-way volume fader to control the singer was somewhat inconvenient, of course, you can balance the two way volume mix of people and after a good organization, so that you can use all the way fader grouping.
In addition to the three band equalizer, is there any way to the stage to the sound in the mixer to tinker with it? It should be inserted using INSERT jack, and we know that the jack is very useful, you can insert effects, pressure limiter, actuator, then the same here we can insert a single channel 15 or even 31 band equalizer sound device to be modified on the singer, how?
Visible and make full use of mixer familiar with the various socket mixer can improve your grades, get more sound processing means to make you work up even more handy.
