Show Calling: How the Caller and Crew Communicate

A live event runs on one voice. The show caller says what happens next and when, everyone else acknowledges and acts, and nobody else gives instructions on the channel. Cues are called in a fixed pattern (standby first, go last), the headset is kept for production talk only, and every handover, of a speaker, a microphone or the job of calling itself, is said out loud.

That discipline is what lets a lighting operator, an audio engineer and a stage manager who can't see each other move at the same moment.

Who does what

Titles vary between theatre, broadcast and corporate events, and on a small event one person may hold three of these jobs. What matters is that each job has a name next to it in the run of show.

Role	Job during the show	Usually sits
Producer	Owns the event and makes the big calls: cut a segment, extend a break	Front of house or roaming
Show caller	Calls every cue to the crew and talent	Control position with a view of the stage
Stage manager	Runs the stage floor: talent, set changes, relays to people not on comms	Side of stage
Technical director / operators	Run audio, video, slides, lights and stream	Control desk, front of house
Timekeeper	Runs the speaker clock and time signals	Where the speaker can see them
Host or moderator	Links segments on stage and controls Q&A	On stage

Rundown Studio's guide to event production roles (June 2026) puts it neatly: the show caller is "the voice of the production", and the stage manager is the caller's counterpart on the floor. The producer decides, including what to cut when the schedule slips; the caller executes.

How a cue call sounds

The convention comes from theatre stage management; the timings below follow the Wikipedia article on theatrical cues. Each cue gets up to three calls:

• Warning: about a minute ahead, so operators can get ready.
• Standby: a few seconds ahead. The operator replies "standing by" and waits.
• Go: the moment to act.

The word order is fixed. As Theatrecrafts' guide to calls and cans explains, "standby" comes at the start of the phrase and "go" at the end: "Standby LX Q 11", then "LX Q 11, go". Operators act on the word "go", so it comes last, after they have heard which cue it is. For the same reason, crews avoid saying "go" in ordinary conversation on headset: as the Wikipedia article on theatrical cues puts it, once the word is heard, the crew will execute the cue.

At a conference, a speaker transition might sound like this:

Caller: "Warning: walk-up music, lectern light, slides for Ortiz."

Caller: "Standby audio 6, lights 4, slides Ortiz." Audio: "Standing by." Lights: "Standing by." Slides: "Standing by."

(Host says the speaker's name.)

Caller: "Audio 6, lights 4, slides... go."

Stage manager: "Ortiz is on, lapel 1 live."

Small events can drop the warning and use standby and go. What you can't drop is the acknowledgement. If an operator doesn't answer "standing by", the caller doesn't call go; they ask again.

Rules for the channel

Clear-Com, which makes production intercom systems, published a short etiquette list, The Miss Manners of Intercom (2011), that still holds:

• Announce clearly when you go "off headset", so the stage manager knows you're offline.
• Turn your mic off when you're off headset, and turn your headset volume right down so it doesn't distract talent or the audience.
• Keep your mic switched off unless you have something production-related to say.
• Keep the conversation to production. Others are listening.
• Don't leave headsets or beltpacks on the floor where they can be stepped on or tripped over.

Most event crews add a few of their own. These are recommendations rather than any standard:

• Say who you're talking to first. "Audio, from stage: lapel 2 is dead, switching to handheld." The person you need hears their name before the message.
• During a cue sequence, only the caller speaks unless something is wrong. Problems take priority; chat waits.
• Say "hold" for anything that's about to go wrong. "Hold lights 4" is clearer than a long explanation while the cue is pending.
• Radios follow the same rules. At events without intercom, walkie-talkies on one channel work, but only one person can talk at a time, so keep calls short and wait for the answer.

Handoffs that need saying out loud

Most crew mistakes happen at handovers, when two people each think the other has it.

• Talent handoff. The stage manager tells the caller when the next speaker is in position, mic on and checked. The caller doesn't cue the host to introduce them until they hear it.
• Microphone handoff. Name the mic, the person and where it goes next: "Handheld 2 to the moderator, lapel 3 back to the rack after the panel."
• Clock handoff. One person runs the speaker clock. If that changes during the day, the new person confirms which segment is loaded and how much time is on it before the old one lets go.
• Calling handoff. When the show caller takes a break, the relief gets a spoken brief: where you are in the run of show, how late or early, what's in standby, and anything unresolved. Then: "You have the show." Answer: "I have the show."

A pre-show comms checklist

Run this 30 to 60 minutes before doors, with everyone at their show position:

1. Every position on headset or radio, answering by name.
2. Everyone holds the same version of the run of show (check the version number).
3. Each operator confirms their first three cues.
4. Stage manager confirms the first speaker's location and mic.
5. Speaker clock is visible from the lectern and from the caller's position.
6. Agree the word for an emergency and who can stop the show, following the venue's procedure.
7. Agree what happens if comms fail: hand signals, cue lights or a runner.

Running the clock while you move around

On smaller events the producer often is the show caller, and doesn't stay at one desk all day. If you run the timer from StageClock, the Control Panel switches to a phone layout with a bottom tab bar (Segments, Timer, Message) on small screens. It is the responsive website, not an app, and the phone has to be signed in with Google.

If several crew screens show the same countdown, it's worth understanding how stage screens stay in sync before you rely on them for cues.

Frequently asked questions

Does a small event need a dedicated show caller?

If you have more than two people operating things (sound, slides, lights, stream), yes, someone should own the calls, even if they also run one of the desks. With one operator and a host, a printed run of show and agreed hand signals are usually enough.

What if an operator misses a cue?

Don't talk about it on the channel during the show. Call the next cue, fix what the audience can see, and note it for the debrief. If the cue still matters, recall it: "Lights 4 again, standby... lights 4, go."

Key takeaways

• One voice calls the show; everyone else acknowledges and acts.
• Standby at the start of the phrase, go at the end, and no "go" in casual conversation on headset.
• No acknowledgement, no go.
• Say every handover out loud: talent, mics, the clock and the calling job itself.
• Write each role's owner into the run of show, and test comms at show positions before doors.
