第一步：检查线路
The first step: check the line
首先要先按照图纸，仔细的检查线路连接，确认济南音响在这方面没有问题。
Must first in accordance with the drawings, check the line carefully connection, confirmed that the Ji'nan sound is no problem in this regard.
第二步：设置音响设备的初始状态
The second step: to set the initial state of sound equipment
设备初始状态设置，把功放输入设置为最小，把所有周边设备的输入输出旋钮设置为0分贝位置或中间位置。按照从前级到后级的顺序通电(先不开功放)，检查所有设备通电正常后，给功放通电。
Equipment to set the initial state, the power amplifier input is set to the minimum, the input and output knob all peripheral equipment is set to 0 dB location or middle position. According to the order of magnitude of the former stage after energized to (first without amplifier), check all the equipment is energized to normal after electrifying, power amplifier.
第三步：初步检查系统状态
The third step: the preliminary check the status of the system
适当开大功放的增益控制，CD中放入一张熟悉的音乐，调整调音台输入电平到基本正常位置。慢慢推起一点调音台推子，听听音箱发出来的声音是否正常，是否失真，如果不正常就立即关机检查。
Gain control proper high power amplifier, in a familiar music CD, adjust the mixer input level to basically normal position. Slowly push up a little console fader, listen to the speaker sends out sound is normal, whether the distortion, if not normal immediately shutdown inspection.
第四步：相位调整
The fourth step: phase adjustment
如果同时使用济南音响超低频和全频的组合，由于分频系统的存在以及安装位置的原因，可能会有交叉频率干扰或延时时间不同引起的相位问题，所以需要进行相位调整。
If you use both Ji'nan sound of ultra low frequency and all frequency combinations, the divider system exists and the reasons of the installation position, the phase problem there may be cross frequency interference or delay time caused by different, so the need for phase adjustment.
第五步： 音箱及系统极性检测
The fifth step: the speaker system and polarity detection
统基本正常后，打开济南音响 http://www.jnzqyx.com/ 所有设备电源，功放电平设置在最大，拉下调音台输出推子，相位仪发生器接入调音台输入通道，打开相位仪电源调整输出增益和调音台输入增益到调音台指示表为0分贝。
The system basically normal, open all the equipment power Ji'nan audio, amplifier level settings at maximum, pull the console output fader, phase instrument access mixer input channels, open phase meter power to adjust the output gain and gain to the mixer input mixer indicator is 0 db.
