Oh there is a console. Let me see… It looks like recording console. Oh, what? You said how do I know this? Simple. Look at how it is formed. There are two big sort of console form, split, and inline console.
There is a fader in a line. That one line is called strip. One strip can accept one signal at a time. At the start point of the strip, there is a preamp. Preamp makes weak mic signal strong. Next, there are some signal processor. EQ, or compressor are kinds of the signal processor. And you can see the fader at next. Fader is kind of resistor that can make the sound smaller.
After the fader, signal goes to master section. At there, signals from every strips are become one, and made to 2 track stereo signals. Finally, this 2 track signals go to speakers, and you can hear the sound.
On the other hand, some console have two fader in one strip. These are called inline console. When record sound, you need two strips to record one signal. But, as I said, one strip can only accept one signal. This makes recording console too big. So, people made two strips in one. This is inline console.
What do you want to do to use console? Recording? Live concert? Choose your console.
