Talkback, Cue and Clean Feed: Gallery Terms Explained Plainly

Why the vocabulary matters in a live gallery

Most arguments in a gallery are not about taste. They come from two people using the same word for different things. When a director says 'cue' and an audio operator hears 'cue' as something else, a microphone opens late or a roll-in starts with silence. That is why we spend time on vocabulary before we draw a single mixing desk layout.

This article is the second of three on sound and gallery workflow, and it takes one narrow angle: three terms explained in plain words. The first article dealt with a checklist; the third will leave these terms behind and look at something else. Here the aim is simple. If you can say what talkback, cue and clean feed mean on your own production, your crew can say it too.

In these autumn weeks, many teams are starting new seasons of studio programmes and conference runs, and new crew members arrive. A short shared glossary pinned near the desk does more good than another hour of rehearsal.

Talkback: who can speak to whom

Talkback is the intercom system that lets the gallery speak to people elsewhere: the floor manager, camera operators, the sound assistant on the studio floor, sometimes a presenter's earpiece. It is not one channel but several, and the first design question is always which groups need to hear which voices.

A common setup separates a production channel, used by the director and producer for instructions, from a technical channel for engineering. The presenter's earpiece is a third, kept deliberately quiet so that only the producer or director speaks into it. Mixing these up is the classic mistake: a technical remark about a faulty cable reaching a presenter mid-sentence.

When we plan a gallery layout, we mark each talkback button on the desk plan with its destination, written in words rather than numbers. A newcomer should be able to read the panel without asking. Daniel Okafor, who signs this piece, has seen more than one run-through lose five minutes to a button that nobody could name.

• Production channel: director, producer, vision mixer, floor manager
• Technical channel: engineering, sound, camera control
• Presenter feed: a single, protected voice

Cue: a signal to act, not a sound

In plain terms, a cue is an instruction to do something at a defined moment. The word is used in three different ways in a gallery, and that is where trouble starts. A spoken cue is the director saying 'stand by, then go'. A visual cue is the floor manager's hand signal to a presenter. An audio cue is a prepared sound or clip waiting to be played.

The distinction matters because each has a different owner. The director owns spoken cues, the floor manager owns visual ones, and the audio operator owns the prepared items. If everyone believes they own all three, nobody commits to the exact timing.

A habit worth adopting is the two-step call. First comes the warning, 'stand by sound effect two', which tells the operator to have a finger ready. Then comes the action word, 'go'. Never combine them. A warning followed by silence is safe; an action word with no warning is how clips fire at the wrong moment.

Clean feed: the version without the extras

A clean feed is the programme sound or picture without anything added that would confuse its recipient. For audio, it usually means the full mix without the contributor's own voice returning to them. For video, it means the picture without graphics or captions burned in.

The audio meaning is the one that causes most live problems. If a remote guest hears their own voice delayed by a second or more, they stumble within a sentence. The remedy is a mix-minus: everything the guest should hear, minus their own contribution. Setting this up needs a dedicated bus on the desk and a clear label so it is not accidentally altered mid-show.

For video, a clean feed is what you send to a screen that will lay its own graphics over it, or to a recording that will be edited later. It is simple in principle, but the signal path must be planned so the clean version branches off before the graphics are added. Tracing that path on paper beforehand is far cheaper than re-patching in the middle of a rehearsal.

• Audio: full mix minus the listener's own voice
• Video: picture before graphics and captions are added
• Always label the bus or output in plain words

Putting the three terms on one page

The practical result of all this is a single sheet kept at the gallery desk. It lists the talkback channels and who sits on each, the three kinds of cue and their owners, and every clean feed with its destination. It need not be pretty. Handwritten and laminated works as well as anything produced in a design package.

We build this sheet during the design stage, once the desk layout is agreed, because the questions it raises often change the layout. A producer who cannot say who hears the presenter feed has just discovered a gap in the plan, and finding that on paper costs nothing.

For live event productions, the same sheet is shared with the visiting crew before the day. Hired-in operators come from different habits and different vocabularies, and ten minutes with the sheet at the briefing removes most of the guesswork. It also gives a calm reference point if something goes wrong on air and voices rise.

Keeping the language consistent over a season

Terms drift. Over a few months a team starts using shorthand, a nickname for a channel, a private word for a prepared clip, and a new operator is left to decode it. Reviewing the sheet briefly at the start of each production block keeps the language honest.

Another habit that pays off is to record the reason behind each rule. Writing 'presenter feed has one speaker only, to avoid technical chatter on air' next to the entry means the rule survives staff changes. Without the reason, someone eventually opens the channel for convenience and the original problem returns.

None of this needs special equipment. It is a matter of agreeing words, writing them down, and using them the same way each time. Gallery work rewards that kind of plain discipline, and the terms here are a sound place to begin.

Talkback, cue and clean feed are ordinary words with narrow meanings in a gallery, and most live mishaps trace back to two people understanding them differently. Agree what each means on your production, write it on one sheet, name who owns each cue, and label every feed in words. The habit costs very little, and it makes a tense live programme noticeably calmer for everyone in the room.
