濟南汽車隔音http://www.szanyuda.com/分析調音臺的輸入信號大體上分為低阻話筒信號輸入和高阻線路信號輸入兩種。其實我們可以把低阻和高阻的區分看成是水壓力或水流速度的不同，比如：高阻輸入的電平高，就好像水壓很大，水流較急，直接輸入到調音臺這個水池里就合適了，不用在中間加什么環節來調整水壓和水流速了；但低阻輸入的電平低，就好像水壓很低，水流很慢，直接輸入到調音臺這個水池里就不合適，我們就需要在大水池里加上一臺抽水機，把低阻的低水壓給它加大，讓水流速度加快。所以調音臺的低阻輸入通道線路里都內置了專門的電路放大器，把低電平放大到合適的電平。這樣用水的特點來形容低阻信號和高阻信號大家應該很好理解了。
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.

濟南汽車隔音http://www.szanyuda.com/談到如何準確界定某一路信號是屬于低阻還是高阻就需要靈活，比如按照標準，電子琴、電貝司、電吉它等屬于高阻信號，要用6.35接插頭輸入到調音臺才可以，但有些地方從舞臺到調音臺之間的連接線太長，線阻大，再加上燈光等系統干擾，讓這條信號線的本底噪聲已經很大了，即使不輸入任何音源信號，在調音臺上把這條線路所輸入通道的增益開大時都會有很大的本底噪音。如果用高阻信號輸入就等于河里的水沒有增加，水質不可以改變，音質當然也沒辦法改變；如果用卡儂插頭從低阻插口輸入信號，河里的一點淺水就會經過低阻放大器的放大，這樣水深了，水質好了，音質也好了。說起來好像不太真實，大家可以試下。我現在做的好多工程，樂隊基本上都是采用卡儂插口從低阻輸入，雖然表面看起來不規范，但實際上也是減少樂隊噪聲的無奈之舉。
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.

濟南汽車隔音介紹現在專業調音臺的輸出部分有很多插口，而且各有分工，不像輸入部分雖然插口多但卻相對簡單，因此連接輸出信號時要慎重。
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.
