English to Polish Tech/Engineering Transport / Transportation / Shipping organizacja koncertu

Wyrażenia pochodzą z dokumentu zawierającego opis wymagań jakie musi spełnić organizator koncertu muzycznego

Day before showday:
load in and set up of sound, lights and video/TV
load in and set up of all risers
load in and set up orchestra equipment/ instruments

After the show:
load out
Please note that the tear down and load out can only start after all the audience has left the hall

A fully qualified electrician must be present from load in of production, during set up and load out, as well as during general rehearsals
Stage must be sufficiently lighted from load in of production until complete load out.

Dla mnie "load in" wydaje się być załadunkiem a "load out" rozaładunkiem ale z kontekstu wychodzi mi, że właśnie na odwrót.
