Henan Puyang Wedding audio equipment sound engineering monopoly wholesale company debugging is a need both skills and experience they need to be carefully and meticulous work of the spirit, when the design and construction requirements are met, debug unreasonable not careful, not only can not achieve the project design effect, but also may make the device operates in the normal state. So before commissioning must fully understand the importance of this work. Henan Puyang wedding professional audio equipment wholesale company carefully before commissioning confirm each piece of equipment is installed, connected correctly, serious inquiry to construction workers construction may affect the use of legacy issues related; carefully before commissioning confirm each piece of equipment is installed, properly connected to the construction workers seriously asking construction may affect the use of legacy issues related; debugging again before carefully read all the equipment manuals, labeling carefully review the design drawings and connection; must be convinced before commissioning and supply voltage power lines no problem; site before commissioning should ensure that no relevant personnel; also to prepare before commissioning the appropriate equipment and instruments.

Need to prepare the equipment and tools: a phase meter, noise generator, spectrum analyzer (with sound level meter), multimeter and so on. Debugging steps: separate boot, check the signal from the audio source began to gradually transfer the case, this check makes sense, since only the signal transmission equipment in each well, amplifier and speakers will get a normal to a properly processed signal before may have a good sound quality, so do this step work, must be patient, must be carefully carried out this step, the speaker and amplifier connected to the first do not worry, it's best to peripheral processing equipment in bypass state. Check the whereabouts of the signal to follow step by step down the signal to check the whereabouts of, and gradually check its level settings, gain, phase and flow conditions, ensure that all devices can get the first-class equipment to provide the best signal, but also able to provide the best signal for the lower, while checking the signal, you should also check its level gradually set up, gain, phase and flow conditions, ensure that all devices can get the first-class equipment to provide the best signal, but also for the lower provide the best signal, check the signal at the same time, you should also observe each device is working properly, is stable, this work Henan Puyang wedding professional audio equipment wholesale company meaning that a single device failure or unstable at this time , it was easier to deal with, it will not endanger the safety of other devices, so this check should not be brought into the next step. Above is correct, it will be connected by one speaker and amplifier system, in a smaller volume, the use of the first phase meter box checked one by one all the phases are consistent stance, ready for the following debugging, the noise generator and equalizer access system, the spectrum analyzer is ready to begin a moderate volume equalizer access systems, the spectrum analyzer is ready to start on moderate volume to debug the equalizer equalizer, spectrum analyzer test points selected in accordance with the relevant standards, Debugging the equalizer principle is: the spectrum analyzer that 20Hz ~ 20kHz audio range, frequency response curve display hall at the base of each test point, straight NOTE: When tested at various points to make volume consistent, then Record the balance after commissioning of the frequency potentiometer position; similarly to a smaller volume and larger volume is consistent, and then record a good equalizer after commissioning of the frequency potentiometer position; similarly to a smaller volume and Jiaming Yang 1393 +90664 +17 69139139 www.69139139.com Zheng * City Milan sun technology market, Building 5, Unit 2, 208, respectively, the larger the volume of the commissioning once again, and then debug equalizer record the results, and finally a few kind of debugging results of data analysis, to find a variety of volume levels were measured by the frequency of the compromise position, and then tested again, and the frequency response curve drawing down the hall, the final position of the frequency equalizer must also be record Note: debugging equalizer, mixer frequency compensation must be placed on 0, the other peripherals to be in bypass mode, the other should be noted that: sound engineering in general, taking into account the hall decorative materials for absorption of high-frequency signal is weak, it can be appropriate to do a little signal above 10kHz attenuation. Henan Puyang wedding professional audio equipment wholesale company completed the above steps, you should be electronic crossover debugging. Divider debugging can be divided into high, medium and low frequency separately, which divider in the system for different purposes. Debugging method also has difference, if, only for subwoofer crossover frequency, that as long as the above equalizer debugging is complete, let alone subwoofer to work to take the crossover bass crossover at 150 ~ between 300Hz, appropriate adjustments to the bass signal gain, feeling the bass level is appropriate may then audition with a full-range system, and then bass and full-range volume stable; if the divider is used in a full range system, requires accurate in accordance with the parameters provided Lou speaker manufacturers do not set high, medium and low frequency crossover, and then repeated for each frequency band signal gain adjustment, until the band's sense of hearing is more balanced, and then refer to the next step in the test spectrum analyzer point test sound pressure situation Henan Puyang wedding professional audio equipment wholesale company
