Control Room Setup Mistakes We See and How to Avoid Them

The most common mistake is choosing equipment first and the space second. A switcher, a replay machine and a stack of monitors get specified from a kit list, and only on the load-in day does anyone discover that the room cannot take them. Ceiling heights, door widths, the distance from the stage and the position of the nearest power distribution all decide what is realistic.

We ask for a floor plan, or failing that a set of photographs and a few measurements, before any kit is allocated. A compact room that suits the venue will always outperform a large setup squeezed into the wrong corner. Seating width matters as much as the desk: a technical director, a vision mixer and a replay operator each need elbow room and a clear line of sight to the wall of monitors.

If the venue is permanent, think about where the room will sit in five years, not only for this show. Moving a gallery later is far more expensive than placing it sensibly the first time.

• Measure doors, stairs and lift sizes before choosing flight cases
• Mark power, network and talkback runs on the plan
• Allow seating width for every operator, not just the desk

A control room is a small heat source with a long list of mains plugs. Monitors, servers, encoders and the switcher itself add up, and a single overloaded spur can end a rehearsal. Organisers often assume that a socket on the wall means capacity for the whole desk, which is rarely true in older halls and temporary structures.

We plan the load in advance, spread it across separate circuits where the venue allows, and keep the most critical equipment on a clean supply with a small backup. Cooling is the quieter problem. A cabin or back-of-house room with no airflow becomes uncomfortable within an hour, and equipment that runs hot is equipment that fails halfway through a long show.

Ask the venue early who looks after electrics and whether an engineer will be on site during the event. A named contact is worth more than any assurance in an email.

• Request circuit details from the venue well ahead of load-in
• Give the room ventilation, or portable cooling if it is enclosed
• Keep critical gear on its own supply with a backup

Cable runs from stage to gallery are where temporary rooms most often go wrong. A route that looks obvious on the day crosses a public walkway, a fire exit or a door that must stay closed. Cables laid in a hurry get trodden on, tugged by passing crew and tangled with someone else's lighting feed.

We agree routes with the venue in advance, protect crossings properly and label both ends of every run with its source and destination. It sounds fussy until a camera drops out mid-song and the fault has to be traced through forty identical leads. Clear labelling lets any crew member find and fix a problem in seconds rather than minutes.

Keep a short written record of what goes where. It helps the next shift, the next day of a multi-day event, and anyone who has to de-rig at the end when people are tired and keen to leave.

• Walk the route with venue staff before laying anything
• Label both ends of every cable run
• Keep a simple written patch list in the room

Picture and sound get the attention, yet a control room lives on talkback. If the camera operators cannot hear the director clearly, or if too many people share one open channel, instructions get lost and the cuts suffer. A common error is assuming that a few handheld radios will do the job of a proper intercom system.

We decide early who needs to speak to whom and set up separate channels where it helps, for example one for cameras and one for stage management. Headsets are checked for comfort as well as function, because a crew wearing them for several hours will notice poor fit. Plan for what happens when a belt pack fails: a spare, already tested, within reach.

Good communication also means agreeing the vocabulary. A short briefing on cue words before rehearsal saves confusion during the show, when there is no time to repeat anything.

• Separate channels for cameras, stage and graphics where possible
• Test every headset and keep tested spares to hand
• Agree cue wording at the first briefing

Many organisers book the control room for the day of the show and nothing else. The result is that the first time anyone sees every source on the wall is when the audience arrives. Faults that would take minutes to solve in a quiet afternoon become emergencies under a live clock.

We push for at least one proper test period with the room fully powered, every camera feeding the desk and graphics loaded. That session is also when the crew learns the room: where the monitors sit, which source is on which button, how the replay machine behaves. Even a short run-through of the opening and closing sequences catches most of the problems that matter.

If budget is tight, reduce the scope of the show before reducing the rehearsal. A simpler production that has been tested will look calmer on air than an ambitious one that has not.

• Book a powered test period separate from the show itself
• Run the opening and closing sequences at least once
• Simplify the show before cutting rehearsal time

The final mistake happens after the broadcast. Equipment gets packed in a rush, cases are filled in no particular order, and the room is left in a state that the venue remembers for the wrong reasons. In a permanent installation, poor handover means the next team inherits undocumented cabling and unlabelled racks.

We plan the de-rig as carefully as the rig. Cases are packed in the reverse of the build order, gear is counted against the kit list and cable routes are checked and restored. For permanent rooms we leave a simple document describing the layout, the patching and who to call with questions.

A tidy finish also protects the working relationship with the venue, which matters when you want to come back. Ten minutes of care at the end saves hours of explanation later.

• Pack in reverse of the build order and count against the kit list
• Restore doors, walkways and floors to how the venue left them
• Leave a layout and patch note for permanent installations
