Before You Commit to a Gallery Build: A Checklist for Studio Integration

Most gallery projects go wrong at the very first meeting, when the conversation turns straight to equipment models. A better opening is to describe the programme: how long it runs, how many presenters and guests appear, how many video sources arrive from outside the building, and how often graphics or pre-recorded items are rolled in. Those answers decide the size of the vision mixer, the number of monitor feeds and the shape of the intercom far more than any catalogue does.

Write the programme down as a plain description of a typical live hour and a difficult one. The difficult hour matters most, because a gallery that copes only on easy days is not reliable. If a news bulletin occasionally takes two remote guests and a breaking item at once, the system must handle that without a workaround.

• Number of cameras and remote sources on a normal day
• Busiest hour you expect, written out
• Who operates the gallery and how experienced they are

An honest audit of existing equipment saves money and avoids awkward mismatches. List every monitor, converter, router and cable run, noting the signal formats each one handles. A mixer that accepts only one video standard will sit uneasily beside cameras that output another, and a converter bolted on later adds delay and another point of failure.

Look at age as well as format. Some older intercom panels and monitors are perfectly sound and worth keeping, while others have connectors that are no longer supported or parts that cannot be replaced. Mark each item as keep, replace or undecided, and bring that list to the planning discussion. It gives everyone the same starting picture and stops the quiet assumption that everything will be swapped.

• Signal formats of each camera, monitor and recorder
• Condition and spare-part availability for older items
• Which items are definitely staying

Cabling is the least glamorous part of a gallery and the part that causes the most trouble when rushed. Decide early how video, audio, tally and control signals will be routed, which runs need to be labelled at both ends, and where spare capacity should be left for later additions. A tidy patch bay with clear labels turns a fault at the start of a live show into a two-minute fix rather than a search behind racks.

Equally important is where people will see things. Monitor placement should follow the director's line of sight and the vision mixer operator's reach, not the convenience of the wall. Sit in the proposed positions with a tape measure before anything is mounted, and check glare from windows and lighting as well.

• Label scheme agreed before any cable is run
• Spare inputs and outputs left on router and mixer
• Monitor positions tested from each operator's seat

Intercom is often added last and then wonders why it feels like an afterthought. On a live programme it is the thread that holds everyone together: the director to the camera operators, the producer to the floor manager, the gallery to the audio desk. Work out who needs to speak to whom, and whether each person needs a private line, a shared channel or both.

From my side as the audio engineer, I would add two checks. First, listen to the intercom headsets in the noisiest moment of a rehearsal, not in a quiet room. Second, confirm that programme sound and talkback can be balanced separately in each headset, because a director who cannot hear a quiet instruction over the show sound will stop trusting the system.

• Map of who talks to whom, and on which channel
• Headset comfort for a full programme length
• Separate level control for programme and talkback

Playout covers everything that is not a live camera: pre-recorded items, graphics, music stings and the recording of the programme itself. Ask how each of these is loaded, who triggers it and what happens if it does not play. A gallery is only as dependable as its fallback, so decide in advance which items have a backup and how quickly the operator can switch to it.

Think also about what happens when a single unit fails mid-programme. Can the vision mixer be bypassed? Is there a second recorder running? Is power protected for at least the time it takes to close a show cleanly? You will not need most of these answers often, but having them written down is what separates an inconvenience from an interrupted broadcast.

• Backup for every playout source that matters
• Second recording path for the programme
• Power protection long enough to finish cleanly

A gallery is not finished when the last cable is plugged in. Agree a testing routine that runs through every source, every output and every intercom channel, and then a full rehearsal with the actual crew in their real seats. Faults that never show up on a bench appear quickly when people are working to a clock.

Finally, settle the handover. Who holds the wiring diagrams and the label scheme? Who is trained to change a source or reroute a signal? What is the first call if something stops working on a live day? Written answers to these questions mean the people running the studio are never dependent on one person's memory.

• Full rehearsal with the real crew before go-live
• Wiring diagrams and settings saved in two places
• Named contact for faults on live days
