You can picture someone putting pieces in place before anything starts: the desks, the cables, the speakers, the people. That work of placing things is one picture; the arrangement left behind when the work stops is the other. Every meaning of set-up is standing somewhere on that line — the placing, or the placed.
From the word’s history
Wiktionary records set-up as a deverbal noun from the phrasal verb set up. The verb means to put something in place so it can work; the noun freezes either that action or its result.
Wiktionary 記載 set-up 是從動詞片語 set up 名詞化而來。動詞的意思是「把東西擺好，讓它能運作」；名詞就是把這個動作或它的結果整包凍結起來變成一個字。這也說明了為什麼「安裝這件工作」和「安裝好的那一套」會共用同一個字。
