济南音响系统的调试不当会给音响设备带来不可挽回的损失，所以在调试音响系统的时候必须严格按要求来执行。
Debugging audio system of Ji'nan properly will give sound equipment irreparable loss, so it must be in strict accordance with the requirements to perform when debugging a sound system.
第一步：最基础的也是很重要的，关系到后面整个系统的运行，开始就是将功放和济南音响接入系统，逐一打开设备的电源，待它们工作稳定后，接入相位仪，在较小的音量下，逐一检查所有音箱的相位是否正确。
The first step: the most basic is also very important, related to the back of the operation of the system, is the beginning of will power amplifier and Ji'nan audio access system, the power to open each equipment, be they work stability, access phase meter, in a smaller volume, check whether the correct phase all speakers.
第二步：把噪声发生器和均衡器接入系统，在此时就应该准备好频谱仪，按照国家有关厅堂扩声质量测试要求，将频谱仪设置在相应的地方。然后以适中的音量对粉红色噪声信号扩声，在20-20kHz的音频范围内，细致微小地调节均衡器的各个频点，在保持音量一致的前提下，使得频谱仪显示的房间频响曲线在各个测试点处基本平直，并且记录好均衡器各频点的位置。同样在音量较小和额定的音量下，再对均衡器进行调试，并记录好，最后将这些记录好的均衡器频点进行相应的折中处理，再利用频谱仪的高一级的档位进行测试，适当修正后就可以确定好均衡器的频点位置了。在此时应该注意，在调试均衡器的时候，调音台的频率均衡点一定要在0处，其他周边处理设备要处在旁路状态。另外，考虑到普通人的听音习惯，可以将均衡器10k以上的信号适当做一些衰减。
The second step: the noise generator and equalizer access system, at this time should be ready for the spectrum instrument, in accordance with the relevant national auditorium sound reinforcement quality testing requirements, the spectrum analyzer is arranged on the corresponding places. Then at a moderate volume of pink noise signal amplification, 20-20kHz in the audio range, each frequency point detailed micro adjustment of the equalizer, while maintaining a consistent volume, room frequency response curve makes the spectrum analyzer display at each test point the basic flat, and recording equalizer every frequency point position. In the same volume is smaller and the rated volume, then the equalizer for debugging, and record, the last records these good compromise equalizer frequency point corresponding, then use spectrum analyzer higher gear test, properly modified can determine the position of frequency point of the equilibrium is good. Should pay attention to in this time, at a time when debugging the equalizer, frequency equalization point mixer must be in 0 place, other peripheral processing equipment to be in a bypass state. In addition, consider ordinary people listening habits, can be more appropriate signal equalizer 10K do some attenuation.
第三步、将电子分频器接入济南音响系统，进行分频器的调试。对于仅作为低音音箱分频的分频器，可以在均衡器调试结束后，让低音系统单独工作，将分频器的分频点取在150-300Hz处，适当调整低音信号的增益，感觉音量适合即可，然后与全频系统一道试听，平衡低音和全频音量;对于作为全频系统的分频器，一定要尽量参照音箱厂家推荐的分频点进行设定，然后反复调整各频段信号的增益，直到听感比较平衡后，再参照后面的声压级测试对增益做进一步的微调即可。
The third step, the electronic frequency divider connected to the Ji'nan sound system, debugging of the frequency divider. For just as the frequency of the frequency divider bass sound box, can in the equalizer debugging finished, let the bass system working alone, the frequency divider frequency points taken at 150-300Hz, properly adjust the bass signal gain, feel volume suitable for can, and then with the whole frequency system is a balance of audition, bass and full frequency volume; for as full frequency divider system, we must try to reference speaker manufacturers recommend the crossover point set, and then repeatedly adjust the frequency band signal gain, until the sense of hearing more balanced, then refer to the back of the sound pressure level test do further fine-tuning to gain.
第四步、声压级的测定。同样将粉红色噪声仪接入济南音响 http://www.jnzqyx.com/扩声系统，象调试均衡器一样选取几个测试点放置声压计，将音响系统的所有设置都调整完毕，最后打开系统的设备，逐渐提升噪声信号音量，要求在保证信号的最佳动态的前提下，调整各设备的增益，使得系统的扩声声压在各测试点都要达到设计的要求，同时需要参考声压级在高、中、低各频段的情况，再对均衡器和分频器略微做一些调整，当然高、中、低各频段的声压级不可能完全相同，一般为了考虑听感的特点都需要在高频的声压级上做一些降低，而DISCO系统的低音系统打开后又需要低频声压级更高些。在声压级的测试时，需要将各测试点的声压级比较一番，如果各点的结果偏差较大，即说明该声场的均匀度不好，就应该认真地进行分析和改进，这个问题将在后面讲述。
Determination of the fourth step, the sound pressure level. The same will be pink noise meter access Ji'nan sound amplifying system, like the debug equalizer as selection of several test points placed SPL meter, all set the audio system are adjusted up, finally opened the system equipment, gradually improve the volume of noise signal, the requirements under the premise of ensuring the best dynamic signal of each device, adjusting the gain, which makes the sound reinforcement the pressure system in each test point shall meet the design requirements, at the same time the need to reference in high, sound pressure level, low in each frequency band, then do some adjustment of the equalizer and the divider is slightly high, of course, the sound pressure level of each frequency band, low may not be completely the same, generally in order to consider the characteristics of sense of hearing need to do some lower sound pressure level at high frequency, and open the bass system of DISCO system after the low frequency sound pressure level higher. In the sound pressure level test, need to sound pressure level of each test point to a point, if the large deviations of the results, which indicate the field uniformity is not good, it should be carefully analyzed and improved, the problem will be in the back about.
