A signal distribution problems
In the case of several sets of speaker sound field case , an equalizer is often used to assign signals to the plurality of amplifier push speakers. But it also may be different brands and models of amplifiers and speakers mixed use, so bring a lot of problems assigned signal impedance match , the level distribution is balanced , speakers have obtained power is normal, and difficult to adjust with a well balanced frequency characteristics of the sound field and speaker .
2 illustrates an equalizer frequency adjustment problems
Common Swallow type three spectral peaks type wave wavy shape , above all tuners human imagination waveform graphics , realistic sound field waveform is actually not needed , we know that the ideal frequency characteristics of the sound field should be relatively flat , If the man with the imagination to adjust the frequency of the sound field characteristic curve , we can imagine the result is counterproductive.
3 limiter adjustment problems
Common furnishings are doing does not work and the role of excessive counterproductive. The former will be used , which will bring serious impact on the system dynamics , the performance of sound unable to pay , the more evident is the strongman sound accompaniment naturally weakened so the singer at a loss.
4 system -level issues
The first is the lack of power amplifier sensitivity control switch opens , followed by the system does not do a zero level adjustment . Sometimes a little push channel mixer output is large, this situation will affect the dynamic and distortion of the system.
5 bass signal processing
The first makes electronic crossover with full-range signal directly to amping speakers ; second bass signals extracted from the system I do not know where to do the processing . If I do not do electronic crossover with a full-range signal directly to amping speaker sound speaker although that does not burn unit , but the unit on its low -fat whole -frequency sounds can be imagined ; But if the system is not the appropriate location from the signals obtained will be brought to the scene to control unnecessary trouble .
6 effects loop processing
Should take the post fader signal to avoid the effect caused by uncontrolled microphone whistle , return conditional occupy one channel , so debugging easier .
7 line connection technology
Common system loud AC interference is caused by the line connecting the process did not do , as well as the system has a balance transfer balance transfer unbalanced and unbalanced connection according to a certain standard connection . Also, do not use low-quality connectors.
8 control problems
Mixer is the control center of the system , sometimes mixing console to do the same high school low EQ equalizer substantial boost or cut then the system is not a good tune , you need to re-commissioning the system , do not over adjust the EQ mixer .

Sound mixer technology common fault analysis: First: the mixer volume fader bad contact When this failure occurs when the tuner will feel our work which will be intermittent sound . Second: the mixer's channel input port failure In the past we used the old Budweiser mixer XLR XLR input port is very easy to " uproot " , when I really began to encounter this failure could not believe my eyes. Third: mixer control system disorders Once using a Soundcraft 16 channel mixer, the total output no signal was found out later on changed to group output , so the next group and no signal is output , and I'm pushing 10 road pushing midnight, went really is the sound of the first 11 channels . Later I went through the AUX output signals, etc. methods , and finally this mixer or completely strike. At this point the show is not being cold field , I just put the CD player to the amplifier signal directly put music to forget . Mixer like so many failures I first met , nor heard of before . Anyway nothing but failure mixer input section , output section , the control section , power section , are generally caused due to aging equipment . Sound technical knowledge in the understanding we rarely encountered in the mixer common faults . Most of these problems are because of the aging of the resulting device itself emerged mixer . In today's audio technology , we will look at these contents , thank you very much concerned about the content of our site .
