Channel strip
A mixer channel's whole signal path, from input to fader, laid out in one vertical column.
On an analogue console every channel is a long, narrow strip: gain at the top, then high-pass filter, EQ, dynamics, inserts, aux sends, pan and the fader at the bottom. The order is not arbitrary — signal flows top to bottom, and an engineer reads the desk like a map of it.
Solid State Logic's 4000 E, from the late 1970s, gave every channel its own compressor and gate, and after that no engineer expected to fetch dynamics from a rack. Every DAW still draws its channels as strips for the same reason, and "channel strip" has become a plugin category of its own: an emulation of a single console channel, very often an SSL one.
