What is a mixer?
 
A mixer, in its purest and simplest form, combines or meshes an array of inputs into a few controllable outputs (hence the name, Mixer). It is pretty much universal that mixers will have at least a volume control on the output. The vast majority will have volume or "level" controls on each input, or "channel". A great many still will have a variety of controls on each channel, from gains or trims to EQ and aux and buses and PFL's and more.
 
The most important aspect of understanding mixers is understanding the channels. On almost all consoles, the channels are laid out in strips; the signal comes in physically through the back of the device, then passes through that channel's various controls from top to bottom, with the gain or trim at the top and the fader at the bottom.
 
Simply look at one of the black circle inputs (XLR's for microphones and snakes), then follow the column of knobs straight down. This is a channel strip.
