Key Takeaways
- The technical rehearsal is not a run-through — it is a test of every system and every cue with every person who will operate or appear in them
- Every speaker must walk the stage during the technical rehearsal — a speaker who does not know where to stand will find an inconvenient position on show day
- The technical rehearsal must run the actual presentation content, not placeholder slides — content-specific cues (video triggers, lighting state changes on specific slides) cannot be tested without the actual content
- The most commonly ignored rehearsal note: "stand further back from the lectern microphone" — brief every speaker on their microphone technique before they arrive
- Schedule 20% more rehearsal time than you think you need — technical discoveries always take longer to resolve than anticipated
What a technical rehearsal tests
A technical rehearsal tests every system that will operate during the event, in the environment where it will operate, with the people who will use it. This means: every microphone on a speaker's body (tested at the volume and movement pattern the speaker will use on stage, not while standing still at a tech desk); every video source switching correctly (laptop HDMI, video playback, live camera); every lighting cue firing in response to the correct trigger; every confidence monitor displaying the correct content for every speaker; every transition executing at the correct time with every department receiving and acknowledging the cue. A technical rehearsal that does not test all of these is a partial technical rehearsal.
Why speakers miss what matters
Speakers invited to a technical rehearsal typically arrive late, deliver a brief extract from their presentation, and leave before the sound check is complete. The production notes they generate from a real rehearsal — stand further back from the microphone, move left so the key light is on your face, begin speaking before the intro video ends — are not addressed because the rehearsal was not long enough for the speaker to receive and absorb them. The pre-brief is the mitigation: before any speaker arrives on stage, they receive a document with the four things they need to know (microphone position, stage marks, confidence monitor location, cue for when to begin). The technical rehearsal then confirms these four things are working, rather than discovering them for the first time.
Content-specific cue testing
A lighting state that changes on slide 12 of the CEO's presentation cannot be tested without slide 12 of the CEO's presentation. A video that plays on a specific cue cannot be confirmed without the video. The technical rehearsal requires the actual content — not a placeholder deck with the same slide count. Production teams that accept placeholder content for technical rehearsals discover that the actual content, when it arrives, has different aspect ratios, different file formats, different transition animations that conflict with the playback system, and specific content moments that trigger cues which were never rehearsed. The content brief must include a hard deadline of 48 hours before the technical rehearsal. Content received after that deadline is tested in the 60-minute gap before show open, when nothing can be fixed.
