What type of rehearsal occurs without the actors, allowing tech crews to practice?

The type of rehearsal that occurs without the actors, allowing tech crews to practice, is known as dry tech. During a dry tech rehearsal, the focus is on the technical elements of the production, including lighting, sound cues, and scene changes, without the presence of the performers. This allows the technicians to familiarize themselves with their tasks, ensure that cues are executed properly, and perfect the timing for when the actors will eventually be present during full rehearsals.

In contrast, wet tech involves rehearsing with the actors present, which allows for the integration of both performance and technical aspects, but does not provide the same focused environment for tech crews to iron out technical details without interruption. Load-in refers to the process of setting up and installing the production elements in the performance space, while performance is when the actual show is presented to an audience.
