What does an SQ operated on cue typically represent?

An SQ operated on cue typically represents a live sound effect, such as a doorbell. This form of cue allows for immediate and synchronized sound to enhance the performance, providing realism and engagement for the audience. Live sound effects are often crucial in creating atmosphere and reacting dynamically to the live action on stage, helping to immerse the audience further in the narrative.

In this context, the other options do not align with the concept of an SQ being operated on cue. Special lighting effects or visual scene changes generally involve predetermined cues that can be programmed and executed without real-time manipulation. A pre-recorded voiceover usually lacks the immediacy and interaction that a live sound effect can provide. Therefore, the answer that correlates directly with the operation of sound effects in real-time during a performance is indeed the live sound effect option.
