Control room fit-outs: six mistakes we see and how to avoid them

The most common mistake begins with a shopping list. A team hears that a certain switcher or monitor size is the standard, buys it, and only then asks how the room will be used. By then the desk is too short for the people who must sit at it, or the monitor wall has no space for the sources the director needs to watch.

We start the other way round. Before choosing any hardware we ask what a typical show looks like: how many cameras, how many graphics and replay sources, who sits where, and who needs to talk to whom. A quiet two-camera panel show and a busy multi-source sports day produce very different rooms.

Write the show down in plain sentences first. Equipment choices then follow from roles and sources, and they are far easier to defend when the budget is questioned. It also stops you paying for capacity that will never be used on air.

If the room has to serve several kinds of programme, plan for the busiest one and make the quieter ones fit inside it, rather than the reverse.

• List every source the director must see at once
• Name each seat and what that person does
• Plan for the busiest show, not the average one

Racks are often placed wherever there happens to be floor space, which usually means somewhere warm, awkward to reach and far from the desk. Equipment that runs hot in a poorly ventilated corner fails at the worst moment, and nobody wants to crawl behind a full rack during a live break to find a loose connector.

Good rack layout is dull work that pays back every week. Heavy items sit low, gear that generates heat gets airflow above and below it, and anything an engineer may need to touch regularly sits at a comfortable height. Patch panels go where a person can read the labels without moving other equipment.

We also leave empty rack units on purpose. A room that is packed solid on day one has nowhere to go when the team adds a second replay machine or a new encoder next year.

Think about noise as well. A rack beside the vision mixer will be heard on every intercom channel, so distance and enclosure matter more than most clients expect.

• Allow ventilation and keep racks out of warm corners
• Leave spare rack units for later additions
• Put patch panels at reading height

Cabling is where good rooms quietly turn bad. A fit-out finished in a hurry, with unlabelled leads and bundles tied in whatever order was convenient, works perfectly until something changes. Then every fault becomes a detective job, and the person doing it is usually under pressure with a show approaching.

The fix is discipline at the start. Every cable gets a label at both ends that matches a drawing, signal types are kept apart where interference is a risk, and lengths are chosen so there is neither a tight pull nor a coil of slack hidden behind the desk.

We hand over a cable schedule with each build, so that a new engineer can follow a signal from camera input to outgoing feed without guessing. That document matters more than people expect, because the person who built the room is rarely the person fixing it three years later.

Keep the schedule up to date. A drawing that no longer matches the room is worse than none, because it sends people confidently in the wrong direction.

• Label both ends of every cable
• Keep a cable schedule that matches the room
• Separate signal types to limit interference

Intercom tends to be the last item discussed and the first one blamed when a show goes wrong. Yet a live gallery runs on spoken instructions. If the director cannot reach the camera operators clearly, or the vision mixer hears three conversations at once, the best switcher in the world will not help.

Decide early who needs to speak to whom, and on which channel. A producer, a director, camera operators, graphics and playout usually need different groupings, and some people must hear several at once while speaking on only one.

Headsets deserve more thought than they get. Comfort over a long day, a microphone that rejects room noise and a clear way to mute all affect how calmly people communicate. Calm communication on air starts with equipment that does not get in the way.

Test the system with the full crew talking, not with one person tapping a button. Problems with crosstalk and levels only show up when everyone is using it at once.

• Map who talks to whom before buying anything
• Choose headsets for long-day comfort
• Test with the whole crew speaking

A wall of bright screens makes a room look impressive, and that is exactly the trap. Monitors are tools for reading information quickly, and a layout chosen for appearance often puts the programme and preview feeds too far from the director's natural line of sight.

Start from where people sit. The programme output and the next source should be the easiest things to see from the vision mixer's seat. Secondary sources, such as individual camera feeds, can sit around them, grouped logically so the eye learns where to look without thinking.

Size and height matter too. Screens mounted too high strain necks over a long production, and screens too small force people to lean in and miss details. Labels on each tile should be large and consistent so nobody confuses one camera with another under pressure.

Colour and brightness settings also deserve a quick check. Mismatched monitors make the same shot look different from one screen to the next, and arguments follow.

• Put programme and preview within easy sight of the mixer
• Group related sources together
• Use large, consistent source labels

The final mistake is treating the first live show as the test. A room can look finished, with every light green on the desk, and still hide problems that only appear when a real programme runs through it from start to finish.

We insist on a full rehearsal with the actual crew, using real sources, real graphics and the real outgoing path. That is when someone discovers that the replay operator cannot see the clock, or that an input drops when two particular devices are switched on together.

Allow time to fix what the rehearsal finds. A schedule that books the rehearsal the day before air leaves no room to act on it, and the findings then go ignored.

Run it twice if you can. The first run exposes faults, and the second shows whether the fixes held and whether the team feels comfortable with the room.

• Rehearse with the real crew and real sources
• Book rehearsal early enough to act on findings
• Run a second pass to confirm the fixes
