Before you commit: a checklist for studio equipment integration

Most integration conversations begin with a shopping list: a mixer of this size, a router with that many ports. I would begin one step earlier. Write down what the studio must put on air in a normal week, and what it must manage on its worst day. A news desk with two guests and a remote link has different needs from a multi-camera show with playback and a band.

From my side of the building, I see the effect of this every time lights go up on a set. The cameras, the monitors in the gallery and the intercom to the floor all have to agree before I can balance a face under live conditions. If the system was specified around an imagined show rather than the real one, I am the first to notice, because the picture on the monitors is wrong and nobody can say why.

Put the programme types, the number of people on the floor and the number of sources on one page. Everything after that is checked against it.

• How many cameras and other sources must run at once
• Which programme formats the room has to handle
• What a bad day looks like: late guest, lost link, extra camera

A router is only useful if it has room for what you connect to it, today and a little beyond. Count every camera, graphics feed, playback machine, remote return and monitor feed, then count where each signal must be able to go: the mixer, the recorder, the gallery wall, the presenter's confidence monitor, the outgoing line.

Clients often count sources and forget destinations, then find the router full when the second monitor wall arrives. Leave modest spare capacity rather than a large amount. Spare ports are cheap compared with replacing a router, but an enormous margin is money that does nothing.

Write the list as a simple table, sources down one side, destinations across the other, and mark which crossings you actually expect to use. It becomes the wiring schedule later, and it makes the quotation far easier to compare.

A studio that works as one system has someone who can say, for any picture on any screen, where it came from and what it passed through. A studio that has grown by adding equipment piece by piece usually has several people who each know part of the chain and nobody who knows all of it.

Before deciding, ask who will draw the signal diagram and who will keep it up to date. Ask whether cable labelling will follow the diagram, so that an engineer arriving at night can trace a fault without a phone call. These are small questions, yet they decide how calm the crew is when something fails during a broadcast.

If the answer is that the supplier will hand over a diagram at the end, ask to see a draft much earlier. Mistakes are cheap on paper and expensive once cables are dressed into the racks.

• A signal diagram that matches the real wiring
• Labels on both ends of every cable
• A named person responsible for updating the drawing

Intercom is the part of a studio that gets the least attention in planning and the most blame when a show goes wrong. A director who cannot reach the floor manager, or an operator who hears two conversations at once, produces visible mistakes on air within minutes.

Decide who needs to talk to whom, and who only needs to listen. Presenters often need a feed of programme sound and a cue line, not the full gallery chatter. Camera operators need clear instructions without the director shouting over the room.

Monitoring deserves the same discipline. Ask how colour will be checked in the gallery, how audio levels will be judged, and whether the monitors will be set up against the same reference. A wall of monitors that disagree with each other leads to endless arguments about what the viewer is really seeing.

• Separate talkback groups for gallery, floor and presenters
• Presenter feed limited to programme sound and cues
• Monitors set up against one common reference

Wiring a room is not the same as proving it works. Ask what testing is included, and what each test shows. A sensible plan runs every source to every destination, checks sync between video and audio, leaves the system powered for long enough to reveal heat and noise problems, and then tests failure on purpose.

That last step matters. Unplug a source, switch off a monitor, drop the link, and see what the crew sees. A studio that has never been broken deliberately will be broken for the first time on air.

Also ask for a rehearsal with real people, not only an engineer pressing buttons. A short run of the actual programme format with the actual crew shows up problems that no bench test finds, such as a monitor placed where a presenter cannot see it.

• Every route tested, not a sample of them
• At least one deliberate failure rehearsed
• A rehearsal with the real crew and format

Before you sign, decide what happens when part of the system fails. A spare mixer is rarely realistic for a small studio, but a spare cable set, a second power route for the key devices and a clear manual fallback often are. Write the fallback as steps a stressed person can follow.

Ask what you will receive at handover: the diagram, the port schedule, device settings saved in a form you can restore, and the list of passwords and addresses. Equipment configurations that exist only in one engineer's head are a risk you can remove with a folder.

Finally, agree how support works after the room is finished: who answers, in what hours, and what is covered. A calm crew is partly a matter of knowing that a call will be answered.

• Saved device settings and a restore routine
• Fallback steps written for a tired operator
• Agreed contact route after handover
