济南汽车隔音http://www.sdcarmusic.com/分析调音台的输入信号大体上分为低阻话筒信号输入和高阻线路信号输入两种。其实我们可以把低阻和高阻的区分看成是水压力或水流速度的不同，比如：高阻输入的电平高，就好像水压很大，水流较急，直接输入到调音台这个水池里就合适了，不用在中间加什么环节来调整水压和水流速了；但低阻输入的电平低，就好像水压很低，水流很慢，直接输入到调音台这个水池里就不合适，我们就需要在大水池里加上一台抽水机，把低阻的低水压给它加大，让水流速度加快。所以调音台的低阻输入通道线路里都内置了专门的电路放大器，把低电平放大到合适的电平。这样用水的特点来形容低阻信号和高阻信号大家应该很好理解了。
Jinan car sound analysis of the input signal input mixer is largely divided into two low-impedance microphone signals and high-impedance line input signal. In fact, we can distinguish between low resistance and high resistance as different water pressure or flow rate, such as: high-impedance input level is high, just like a big pressure, flow more acute, directly into the mixer the pool on the right, and not in the middle of what part to adjust the water pressure and water flow rate; but low-impedance input level is low, as if the water pressure is low, the water flow is very slow, directly into the mixer of the pool inappropriate, we need to add in a flood pond pump, the low pressure and low resistance to it increased, so that the water flow faster. Therefore, low-impedance input channel mixer circuit are built in a dedicated circuit amplifier to be amplified to an appropriate low level. Such water features to describe low-impedance and high-impedance signal it should be well understood.

济南汽车隔音http://www.sdcarmusic.com/谈到如何准确界定某一路信号是属于低阻还是高阻就需要灵活，比如按照标准，电子琴、电贝司、电吉它等属于高阻信号，要用6.35接插头输入到调音台才可以，但有些地方从舞台到调音台之间的连接线太长，线阻大，再加上灯光等系统干扰，让这条信号线的本底噪声已经很大了，即使不输入任何音源信号，在调音台上把这条线路所输入通道的增益开大时都会有很大的本底噪音。如果用高阻信号输入就等于河里的水没有增加，水质不可以改变，音质当然也没办法改变；如果用卡侬插头从低阻插口输入信号，河里的一点浅水就会经过低阻放大器的放大，这样水深了，水质好了，音质也好了。说起来好像不太真实，大家可以试下。我现在做的好多工程，乐队基本上都是采用卡侬插口从低阻输入，虽然表面看起来不规范，但实际上也是减少乐队噪声的无奈之举。
Jinan car noise talking about how exactly to define a road signal is part of the low resistance or high resistance on the need to be flexible, for example in accordance with the standard, organ, electric bass, electric guitar and so on belong to a high-impedance signal, to use 6.35-plug input to the mixer we can, but in some places from the stage to the connecting line between the mixer too long, line resistance, coupled with the lighting and other system disturbances, so that the background noise signal line has been great, even if you do not enter any audio signal, the mixer circuit that put the channel's input gain is large, there will be open a lot of background noise. If a high-impedance input signal is equal to the river water has not increased, water quality can not be changed, of course, no way to change the sound quality; XLR plug if the input signal from the low-impedance jack, the river will go through a little shallow low resistance amplifier amplification, so the depth of the water quality good, sound good, too. Said it does not seem real, you can try it. I have been doing a lot of projects, bands are basically from low-impedance XLR input, although seemingly not standardized, but is actually quite upset reducing noise band.

济南汽车隔音介绍现在专业调音台的输出部分有很多插口，而且各有分工，不像输入部分虽然插口多但却相对简单，因此连接输出信号时要慎重。
Jinan car sound output section describes Mixer now there are many jacks, and each division, unlike the multi-input socket part though but relatively simple, so be careful when connecting the output signal.
