Inside a temporary control room: how an outside broadcast crew works

Arriving before anyone else

The crew is usually on site well before the first band soundchecks. A temporary control room starts as a patch of ground, a marquee corner or a borrowed room behind the stage, and our first job is to decide where everything will sit. We walk the route between the stage, the camera positions and the production area, because every metre of cable we run has to be protected, labelled and kept out of the way of crowds and vehicles.

Hannah Brooks has already sent the kit list and schedule by then, so the walk is about confirming what the plan could not tell us: where the power really comes from, how far the ground slopes, and whether the venue's own staff have changed anything since the site visit. These small checks decide whether the day runs calmly or becomes a series of repairs. We would rather spend an hour on them than an afternoon fixing problems later.

• Confirm power supply and a backup route
• Walk the cable path from stage to control room
• Agree radio channels and a meeting point

Turning a space into a control room

Once the position is agreed, the room goes up in a fixed order. Power distribution first, then the equipment racks, then the monitor wall and the desks for vision mixing, replay and graphics. We build it the same way each time so that a crew member who has worked one of our rooms can sit down in another and find everything where they expect it.

The monitor wall takes longer than people imagine. Every camera, graphics feed and return signal needs a screen, a label and a check that the picture is the one it claims to be. Intercom comes next, because a control room without clear talkback is just a row of screens. Headsets are tested one by one, and each camera operator is asked to confirm they can hear the director before we move on to anything else.

Cabling and the unglamorous work

Most of an outside broadcast is cable. Camera feeds, intercom lines, power and network links all have to cross open ground, doorways and sometimes public walkways. We use covers and ramps where people will walk, and we keep video, power and audio runs separated so that interference does not creep into a picture halfway through a set.

Every cable is labelled at both ends, and we keep a simple diagram of what goes where. It looks fussy until a camera drops out ten minutes before doors open and someone can trace the fault in a minute rather than twenty. The same diagram makes the strike at the end of the night much quicker, because nothing has to be guessed or traced by hand in the dark.

• Label both ends of every run
• Keep power and signal cables apart
• Cover anything the audience might cross

Rehearsal, cues and the first picture

When the room is built, we move to checking the pictures themselves. Each camera is lined up for exposure and colour so the cuts match, and the vision mixer runs through the likely shots with the operators. A line check with the sound team confirms that the feeds we are taking line up with what the audience will hear.

If there is time for a rehearsal, it is the most useful hour of the day. The director and the show caller run the cue sheet against the real stage, and small problems appear that no plan would have shown: a camera position that loses the singer behind a speaker stack, a lighting change that crushes the picture. We note these and fix them while there is still time to do so calmly.

Running the show from a small room

During the event the control room goes quiet in a particular way. The director calls shots, the vision mixer cuts, the replay and graphics operators wait for their cues, and talkback is kept short. We ask everyone to say only what the person receiving it needs, because a crowded intercom is how a missed cue happens.

Things still go wrong on a live night. A battery dies, a radio mic drops, rain reaches a cable joint. What matters is that every member of the crew knows who decides and who fixes. The director stays on the show while an engineer deals with the fault, and we tell the producer plainly what has happened and how long it should take. Calm, short reports keep a problem small.

• Keep talkback brief and specific
• Separate the person fixing from the person directing
• Tell the producer the facts and the likely time

Packing down and what we leave behind

The show ending is not the end of our day. Strike begins as soon as the last shot is cleared, and it is run in the reverse order of the build so that nothing is left behind. Cables are coiled and checked as they come in, and any damaged lengths are set aside rather than returned to the stock.

Before leaving, we walk the site again with the venue contact and confirm that ground, covers and power points are as we found them. In the days after, Hannah collects notes from the crew on what worked and what slowed us down, and those notes shape the kit list for the next job. That habit of small corrections is most of what makes a temporary room feel settled.
