<br> Mixer is a modern sound system's control center, is a sound program broadcast and recording in important equipment. <br> <br> In the entire sound system, need random adjustment is a sound mixer, mastered the mixer input channel adjustment method ., which basically mastered the signal source hardware control technology. General mixer consists of 4 parts, namely, input on most (IA), frequency Equalizer (EQ), sound and image positioning section (PAN) and volume control (FADER). The following .describes the four parts of the control technology and methods. <br> <br> Input on most <br> <br> In a mixer on a per input element has a fixed Attenuator (PAD), attenuation range are usually 20-30dB, .gain controller (GAIN) and a peak led (PEAK). When the audio source signal is low, if you just simply increase the gain, the destruction of the input signal to noise ratio; if gain down too small, you cannot get enough output .level. <br> <br> The equalizer (EQ) of the regulation <br> <br> Mixer input channel Equalizer (EQ) is used to input signal tone compensation, usually a mixer of equilibrium (EQ) is divided into three stages ., namely, high frequency, medium-frequency and low frequency. There are four stages, namely, high frequency, low frequency and high frequency, and low frequency. <br> <br> 1. the equalizer (EQ) of parameters and control .function <br> <br> High frequency band (HIGH) primarily affect the treble zone of musical instruments and high harmonics, lifting, metal sound increase, Apical, enhance the tone more too much will make a significant increase in noise. You can remove .noise attenuation, the attenuation is too much treble district of sense will be lost. <br> <br> In the band (MID) frequency, if center frequency tuned in, the main influence 3kHz instruments and voices of the treble. Elevated tone bright ., hard texture. Raise too many auditory fatigue, attenuation, music or sound sense of balance tend to bass. If center frequency tuning impact mainly in 1kHz instruments and voices in tempo. Lifting time definite, voice timbre contour will forward, after the shrink when .sound attenuation. If center frequency tuned in, the main influence 500Hz instruments and voices in the bass. When upgrading, enhancing timbre rich powerful appears on the phone too much, when the sound timbre of attenuation is hard, balance tends too much treble, decay .experiments thinning. <br> <br> Low frequency band (LOW) low-frequency bass main influence musical instruments, upgrade when the tone is thick. More easily when sound attenuation, effectively remove background noise and hum. <br> <br> .2. Equalizer (EQ) of the regulation and control skills <br> <br> Moderator of the general thematic programmes for women, in a mixer for balanced compensation, to promote high-frequency appropriate to raise around 4dB audio clarity and luminance, but .this section does not mention too high, otherwise easily lead to auditory fatigue. On high frequency attenuation above for 6kHz, to eliminate possible teeth tone. Low frequency band near the 500Hz attenuate 6-8dB to eliminate low-frequency too strong. <br> .Sound like a potentiometer (PAN) of the regulation <br> <br> Sound like a potentiometer (PAN) role is primarily to stereo balance processing and stereo sound field reassignment treatment. For example, song and dance halls of accompaniment Orchestra, with stereo .sound reinforcement and restore, make it clear stereo position. <br> <br> Included-left and right channel audio source azimuth of depth, ie PAN knob off center location, according to the band in the position of the stage, the atmosphere and .the recording of sound and image processing techniques for different ranges of sound and image orientation of the depth of the regulation, to achieve perfect stereo sound field effect. <br> <br> Channel attenuation potentiometer (FADER) of the regulation <br> < .br> Channel attenuation potentiometer (FADER) commonly known as faders, it has two functions: one is to control the size of the volume of this road, the second is to adjust the balance between the sound source. To obtain ideal to listen to the .effect that the tuner it is necessary to know the singer singing characteristics, but also to the familiar songs, songs of the climax, the actor should bring excitement down into small, when the song lyric and exquisite weak sound, it needs to turn the volume .up. <br> <br> In addition, when you enter your jumps, speakers produce a whistling or peak led is lit, it was hurried down the channel faders, such actions are wrong, because pull down the faders just reduces the output volume ., and enters the mixer level remains high, very easily lead to clipping distortion. In such cases, only gain knob counterclockwise to decrease gain to effectively eliminate clipping distortion. <br> <br> Described above is the main function of the input channel mixer .knob on the most basic regulation methods, to be truly comfortable master mixer control technology and tuning techniques, also recording technicians have continuously strengthening its own artistic accomplishment of music, electro-acoustic and electronic technology knowledge, accumulated experience, thereby increasing regulation and tune the .level of technology and sound art. <br> <br> <br>.
