Start with who sits where
Most layout problems in compact control rooms begin with equipment lists rather than people. Before looking at any desk or rack, write down every role that will be in the room during a normal production: director, vision mixer operator, sound operator, graphics, replay, a producer or floor manager on talkback. Then mark which of them need to see each other, who needs to hear whom without a headset, and who must reach a control surface without leaving their seat.
I ask clients to draw the room to scale on squared paper and place a chair for each role at a realistic width, roughly sixty centimetres per person with elbow room. It is a dull exercise, but it shows quickly when five roles will not fit along a three-metre desk. Count the busiest show you expect to run in the next two years, not the typical one, because moving a desk later costs far more than allowing a spare seat now.
- List every role present on a normal show and on the busiest one
- Draw the room to scale with a chair for each person
- Note who must see, hear or reach whom
- Allow one spare seat for guests or trainees
Sightlines and the monitor wall
Monitoring decides whether a small room feels calm or cramped. Work out the viewing distance from the director's seat to the main programme and preview screens, and check that nobody has to turn their head sharply to follow the picture. Screens mounted too high are a common complaint after a build, because crews end up looking upward for hours and the angle is hard to correct once a wall is fixed.
Decide early how many sources genuinely need their own display and which can share a multiviewer. Fewer, better-placed screens usually serve a compact room better than a wall of small ones. Check the glare from room lighting and from any window, and think about whether the programme monitor can be seen from the studio door, since a floor manager often glances in without entering.
- Measure viewing distance and head movement from each seat
- Keep screens low enough to avoid neck strain
- Separate must-have displays from those a multiviewer can carry
- Check reflections from lights and windows
Intercom and talkback decisions
Intercom is easy to leave until last and awkward to correct afterwards. Decide who needs a dedicated channel, who shares a party line, and whether the studio floor is reached by headset, loudspeaker or both. In a small room with several people speaking at once, an unclear arrangement quickly leads to talking over one another during a live moment, which is the situation you most want to avoid.
Ask whether the system will need to connect to remote contributors or a second studio in the near future, and leave room for it. Think about how a headset is worn for long periods, where spare belt packs are kept, and what happens if one station fails mid-show. A simple fallback, such as a second talkback route to the floor manager, costs little and is worth agreeing before the first transmission rather than during it.
- Assign channels by role, not by habit
- Decide how the studio floor is reached
- Plan a fallback route to the floor manager
- Leave capacity for remote contributors
Power, cooling and cable routes
A compact room concentrates heat and cabling in a small space. Add up the power draw of monitors, the vision mixer, converters and any computers, then compare it with the circuits actually available rather than the number of sockets on the wall. Put critical items on a clean supply separate from kettles, heaters and general office loads, and ask an electrician to confirm what the room can safely carry.
Equipment racks that run warm will shorten the life of everything in them, and fans placed too close to a microphone or a talkback station become audible on air. Plan cable routes in trunking or under a raised surface so that nothing is trailed across the floor. Label both ends of every run at the time of installation, because relabelling a hundred unmarked cables later takes longer than the installation itself did.
- Total the power draw and compare with available circuits
- Keep broadcast equipment off shared domestic loads
- Place racks where fan noise cannot reach microphones
- Label both ends of every cable at installation
Room for the next change
A control room that fits today's show exactly will often fail after the first change of format. Leave modest spare capacity: a few unused inputs on the mixer, a free rack unit or two, and a desk that can take another operator position without being rebuilt. This does not mean buying equipment you do not need, only avoiding choices that close off the next step.
Check also how people will actually use the room: where coats and bags go, whether visitors can stand behind the director without blocking a door, and how easily a technician can reach the back of a rack. Walk through a full show start to finish, from first power-up to shutdown, with the crew who will run it. The awkward moments you notice on paper are far cheaper than the ones you meet in the build.
- Keep spare inputs, rack space and a possible extra seat
- Allow access to the back of racks
- Walk through a full show on paper with the crew
- Plan space for visitors without blocking exits
A compact control room works when the decisions are made in a sensible order: people first, then sightlines, intercom, power and room to grow. None of the checks above needs special tools, only an afternoon and the crew who will use the space. If a question on the list has no clear answer yet, treat that as the thing to resolve before anything is ordered or fixed in place.
