【School】 how weak and flexible to use mixer equalizer.

<br> <BR> mixer is one of the most important role in the modification of the sound, but now the mixing console (except high) tones are part of the three-stage equalizer almost without exception: high-frequency, low frequency re- .plus a frequency parametric equalizer, that treble frequency lOkHz or 2kHz, Bass 80Hz or 100Hz, some are labeled HI and LO in English for you to guess, but you guess the above parameters will be pretty close. .IF is the adjustable parameters, parametric equalizer for the frequency most people will use, and that align with the frequency of a frequency knob, then use the button above to boost or cut it wants. .<BR> <BR> But some careless high bass knob sound engineer was also the case law cook, to see the bass knob on the 80Hz or 100Hz think this channel is coming in what the electric guitar, that this frequency did not put it to use .to the left cut out, to see the lOkHz or treble button will toggle 12kHz spin to the left to think that this channel is electric bass can not, and this wrong, because it involves the three-band equalizer .characteristics of knowledge, in general, parametric equalizer mixer IF is a high Q, narrow-band bandpass filter, which is a characteristic peak frequency, frequency band is narrow, but the frequency can move around. .<BR> <BR> Used in conjunction with the sweep knob is a knob to increase and decay, while the treble and bass knob is a low-Q and wideband bandpass filter, its frequency curve is a scaffolding-type .and, therefore, the subject of 80Hz bass knob is its center frequency, which is based on 80Hz as the center of a region, its upper limit may be extended to 300Hz, while the lower limit may be extended to 20Hz. .Treble knob is true, 10kHz or 12kHz is also its center frequency, it is the extension may reach 16kHz, the next extension may be 5 ~ 6kHz, it is not indiscriminate all it decay or increase is extremely wrong, as it .is not a point you exterminate, but a sound area. .So sometimes the sound of the band feel thin, but can not find the reasons, then take a look at the bass EQ knob is in the over-attenuation position, and maybe that is the problem. .<BR> <BR> Addition to the equalizer but also have a button with the frequency that the gain in the number of buttons under the mixer will have a low cut button, which is actually a high-pass filter, generally indicated above, removed .frequency is 75 ~ 80Hz, it is said that when the button is pressed when the frequencies below 75Hz will be blocked out. .So when low-frequency knob is also work? .Of course, at work, it 75Hz still enhance the role of the above bands. .<BR> <BR> In the role of three-band equalizer is the biggest IF parametric equalizer, and it was a good thing, it can identify the need to address the frequency of the sound to make accurate compensation, in the high-end mixer .generally set the two IF parametric equalizer, one is HIMID high frequency, its frequency range is 600Hz ~ lOkHz, the other is LOMID low-IF frequency range it is 150 ~ 2400Hz, unfortunately only one console in general, it .The frequency range is generally 200 ~ 6000Hz. .<BR> <BR> Sometimes this kind of situation: a relatively thin singer's voice, which means about its frequency 250Hz for promotion to make his voice sound more full, but while his voice is not very bright ., also needs to improve his 2000Hz or so to give him more during their voices, then you will find a trade-off frequency parametric equalizer will simply not enough, then is not there a way to make your mixer a multi-frequency .parameters? .Can, then if your mixer has a direct output jack DIRECTOUTPUT it easy to handle, and generally direct the mixer is taken from the equalizer output jack after the pre-fader, and now you need from the singer channels .out a signal directly to the output jack, insert all the way to another channel, and now you have two IF parametric equalizer for your use. .<BR> <BR> You can use the first channel parametric equalizer compensation 250Hz, and then use another channel's parametric equalizer to compensate for the 2000Hz, of course, the first channel at this time do not push the volume fader, the sound from the .Road fader send, you can also send audio fader with the first way to make than the utility and the second way, of course, if you are interested, so you can get more IF equalizer, you can make more sound .modification, but there are two frequency parametric equalizer for embellishment on the singer's voice has been sufficient, if your mixer has no direct output jack, is not there way to get two IF parametric equalizer it? .<BR> Still, you can access from the singer AUX auxiliary output that signal all the way out, and then return to the other channels, the same IF you can get two parametric equalizer, the auxiliary output that is best for AUX1 fader .before, so do not push the fader from the road can be dealt with the signal to another way to continue treatment, pre-fader if you are the band occupied AUXl, you can also use the fader or post-AUX2 AUX3, .At this point mainly to the channel 1, first IF channel 1 parametric equalizer compensation 2500Hz, this channel-based sound, and then the other channel parametric equalizer to compensate for the frequency 250Hz, the sound effect modified push slowly, listening to .to the singer's voice can become full. .<BR> <BR> But note that this case is a two volume sliders to control the singer was somewhat inconvenient, of course, can also balance the volume of the two way mix of people after the grouping, which can be used to push all the way grouping .son. .<BR> <BR> Addition to the three-band equalizer, are there any way to the sound mixer to make modifications on it? .Then inserted INSERT jacks to use, and we know that this jack is very useful effects can be inserted, pressure limit, 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? .<BR> <BR> You simply can be adjusted freely to sound, but remember: sometimes self-defeating the modification of the transition, but the sound get very ugly, but here they give you a modified approach to sound only. .Another string in the main channel 31 band equalizer generally, in fact, there can also be modified for the singer sounds like your channel equalizer 2500Hz in the singer made a compensation, you can balance to in paragraph 31 .device is about 200 ~ 300Hz band can reach to make some compensation to enhance the effect of the human voice. .<BR> <BR> Visible mixer familiar with and take full advantage of the various jacks enable you to enhance the quality mixer, to get more sound processing means to make you work up even easier. .<BR>.
