Before You Sign Off a Gallery Build: A Pre-Decision Checklist

Walk the path on paper, one signal at a time. A camera feed leaves the studio floor, passes through patching, reaches the vision mixer, is routed to monitors and recording, and finally goes to playout or the outgoing link. At each stage ask what format it is in, what converts it, and what happens if that device fails. Many on-air problems come from a quiet conversion step nobody remembered to document.

Ask for a signal flow diagram before any cable is pulled, and read it as a director would rather than as an engineer. Can you tell where a picture comes from when a monitor shows the wrong thing? Are labels on the drawing the same as labels on the equipment? A clear diagram is the cheapest piece of insurance in the whole project, and it should be handed to your team, not kept by the installer.

Intercom is the part of a gallery people notice only when it fails. Decide who needs a dedicated channel, who shares one, and who must be able to break in. Floor manager, camera operators, audio, graphics and the director all have different needs, and a single party line rarely serves a news programme with guests and a tight running order.

Think about the studio floor as well as the control room. Can the floor manager hear the director while a presenter is speaking? Is there a way to talk to one camera without the whole crew hearing? Ask how the system behaves if a belt pack loses its battery halfway through a bulletin. A sensible answer includes spares, a simple fallback and a note in the written handover rather than a verbal assurance.

Installation is finished when the equipment is mounted. Integration is finished when the system has been proven under realistic conditions. Ask what the test plan covers: every source on every input, every monitor feed, intercom between each pair of positions, and a full rehearsal with the crew who will actually use it. A supplier who proposes only a quick power-on check has not described a test.

Agree in advance what counts as a pass. For example, a ninety-minute rehearsal run to the real running order with no unexplained dropouts, followed by a list of snags with owners. Keep that list. Items that seem small in mid autumn, such as a flickering monitor or a noisy fader, tend to grow into complaints when the evenings draw in and the schedule gets heavier.

A gallery that only one engineer understands is a risk, however well it works on the day. Ask what you will receive at handover: wiring schedules, patch lists, device settings, labelled photographs of the racks, and a short operating guide for the people who run the studio each week. Check that these are written for your team, in language they use.

Ask also who you call when something fails during a live slot, and how quickly someone can reasonably be expected to respond. Be wary of vague promises. A modest, clearly stated arrangement is worth more than a bold one. Finally, plan a short follow-up visit a few weeks after go-live, when real use has revealed what rehearsal did not. Put it in the schedule from the start.

The last items on the checklist are internal. Who owns the decision, and who will operate the gallery daily? Have the people who will sit at the vision mixer seen the proposed layout? Is the room itself ready, with enough power, cooling and cable routes, and is there somewhere to work during the build? These practical points are easy to leave to the end and hard to resolve then.

Then set realistic expectations about disruption. Studios rarely stop entirely, so agree which days are safe for noisy or intrusive work and which are protected for broadcast. If you can answer all of these questions calmly, you are in a good position to compare quotations on substance rather than on the length of the equipment list.
