Studio Equipment Setup Mistakes That Cost You Air Time, and How to Avoid Them

The faults we meet most often when a news or live studio is fitted out, from cable runs to control desk layout, and the plain habits that stop them returning.

Treating cabling as the last job

The most common mistake I see in a new or refitted studio is that cabling is left until everything else is in place. Cameras are positioned, the desk is bolted down, the set is dressed, and only then does someone ask how the signals will actually travel. By that point the shortest route is blocked, so cables end up taped across floors, bundled with power, and looped behind furniture where nobody can trace them.

From an audio point of view this matters a great deal. Microphone lines run beside mains feeds pick up hum that no amount of mixing will remove cleanly. It is far cheaper to plan routes before the floor is finished than to chase a buzz during a live bulletin, when the presenter is already in position and the clock is running.

The fix is dull but effective: draw the cable paths first, separate signal from power, and decide where each run enters the gallery before any equipment is placed.

Keep microphone and power runs apart wherever they must cross
Cross at right angles, never in parallel
Agree entry points to the gallery before furniture arrives

Skipping labels and a patching record

An unlabelled cable is a problem waiting for the worst possible moment. When a camera drops out five minutes before going live, the person fixing it needs to know in seconds which connector belongs to which source. If every lead looks the same and nobody wrote anything down, the fault turns into a guessing game.

Labelling feels like a chore during installation, when everyone is keen to see pictures on the monitors. It pays back the first time a different operator covers a shift, or a new member of the crew has to find an input quickly. A simple, consistent scheme beats a clever one that only the installer understands.

We keep a patching record alongside the labels: a single sheet listing every source, its destination, and the desk channel it arrives on. When something changes, the sheet changes the same day. That habit alone removes most of the panic from fault finding.

Label both ends of every lead, not just one
Use the same wording on labels and on the desk
Update the patching sheet whenever anything moves

Designing the control desk around the equipment, not the people

Control desks are often laid out to suit the kit: the biggest unit goes where it fits, and the operators adapt. The result is a gallery where the director cannot see the monitors properly, the vision mixer reaches awkwardly for the controls, and the audio position sits where nobody can hear clearly over the room.

Think about who sits where during a live programme and what each person needs to see and hear. Sightlines to the preview and programme monitors come first. Then reach, so the controls used most often sit under the hands without stretching. Then sound, since the audio operator needs monitoring that is not drowned out by talkback from the next seat.

I would rather lose a little tidiness than put an operator in a position where they cannot do the job comfortably. A gallery that is slightly untidy but easy to work in will run better than a handsome one that fights its crew every night.

Leaving power and grounding to chance

Power distribution is rarely exciting, so it gets less attention than it deserves. Equipment plugged into whichever socket was nearest, extension strips daisy-chained behind racks, and no clear idea of what shares a circuit: these are the conditions under which a studio develops intermittent faults that nobody can explain.

Poor grounding is the quiet culprit behind many audio problems. A low hum that appears only when a certain camera or light is switched on usually points to a loop or a shared supply, not a faulty microphone. Replacing the microphone solves nothing.

Plan the power at the start. Know the load on each circuit, keep sensitive audio and video equipment on clean, well-organised supplies, and avoid stacking adapters. If a lighting rig and a sound desk share a feed, expect trouble sooner or later, and decide deliberately rather than discover it on air.

Avoid daisy-chained extension strips behind racks
Investigate any hum before swapping microphones

Testing the studio empty rather than under load

A studio that works perfectly with two people in it can behave very differently with a full crew, a presenter wearing a radio microphone, lights at working level and every camera live. Many faults only appear when everything is running together, so a quiet acceptance check with the room empty proves less than it seems to.

Before handing a studio over, run a full rehearsal that resembles a real programme as closely as possible. Bring up all the lights, use the real microphones, move the cameras through their usual shots, and keep it going long enough for heat and interference to show themselves. Listen carefully to the audio throughout, because that is where hidden problems often surface first.

Write down whatever goes wrong, however small, and fix it before the first broadcast. A twenty-minute scruffy rehearsal now is worth far more than a polished apology afterwards.

Rehearse with the full crew and real presenters
Run long enough for equipment to warm up
Record every minor fault and close it off

Forgetting that the studio will need to change

The last mistake is building a studio as though it will never alter. Formats change, a new programme needs another camera position, a guest chair appears, and a fixed installation with no spare capacity makes every adjustment expensive and disruptive.

Leave room to grow where it costs little to do so. Spare cable capacity in the conduits, a few unused inputs on the desk, and some slack in the lengths of key runs all make later changes quicker. None of this needs to be elaborate, and none of it should be a reason to over-build.

Keep the documentation honest, too. If the installation drifts from the drawings, the drawings become useless and the next person to touch the studio starts from nothing. A reliable setup is one that stays understood by the people who work in it.

Most setup problems are not exotic. They come from rushed cabling, missing labels, a desk laid out for the kit, careless power and a rehearsal that never looked like a real show. None of the fixes cost much when made early, and all of them are tiresome to make late. Plan the routes, label what you install, test under load, and leave the studio room to change. Those habits keep a gallery calm.
