AV System Commissioning Checklist

A commissioning checklist for one audio-visual room — classroom, meeting room, lecture hall or divisible space: electrical safety and grounding, the rack and cabling, every display and input, speakers and measured sound levels, microphones and feedback, hearing assistance, the touch panel, a live test call, recording, network settings without passwords, lighting and room combining, a soak test, user training, as-built documents, a snag list and the client's sign-off.

Room and Project

Which room, what kind, what it contains, and who is commissioning it.

Tick everything installed. Each section for something not ticked folds away.

From the back of the room and from the presenter's position.

Electrical and Physical Safety

Nothing a user can touch is live, sharp or likely to fall.

Use a non-contact tester and then a meter between the metalwork and a known ground.

V

Feel or measure exhaust vents on displays, projectors, amplifiers and processors.

Rack and Cabling

Built to the drawings, labeled at both ends, dressed, cool and serviceable.

°F

Commonly somewhere around 100–110 °F at the top of the rack. The specification decides.

Acceptance and Sign-Off

The commissioning engineer signs that it is done; the client says whether they accept it.

AV commissioning is the last job before a room goes into use: the integrator or an independent engineer goes through the finished installation and proves that it is safe, built the way the drawings say, and does everything the client was promised — every source on every screen, sound that is clear in the back row, microphones that do not howl, a call that connects, a panel a visitor can use without a manual. This checklist covers one room, opens only the sections for the equipment that room actually has, and ends with a snag list and the client's signature. Fill it in here and download a PDF without an account, or speak while you walk, and the document writes itself.

Commissioning is not the same as installing

An installer finishes when everything is fixed, cabled and powered. Commissioning starts there and asks a different question: does the room work for the people who will use it? A projector can be perfectly mounted and still show a soft, stretched image because the source runs at the wrong resolution. A ceiling full of speakers can be wired correctly and still leave the back third of a lecture hall struggling to hear.

That is why the form records measurements and tests, not just ticks: the voltage found on touchable metalwork, the rack temperature after the system has run for an hour, the background noise and program level in the room, the test call and who answered it, how long the system ran in its soak test.

One room per form, and only what the room has

Each room gets its own checklist, because the snags, the re-test and the client's signature all belong to that room. The first section asks what kind of room it is and what it contains. A huddle room with one display and a conferencing bar shows a short form; a divisible lecture space with a hearing loop, wireless microphones, recording and lighting control shows all of it.

Displays and input points are lists, so a room with three screens and five wall plates gets three and five entries, each with the checks for its own kind — keystone and screen limits for a projector, touch alignment for an interactive display.

The order to work in

Start with safety: nothing in reach of a user should carry stray voltage, have a sharp edge or hang from a ceiling without a secondary fixing. Then the rack and cabling, because a fault found later in a test is usually a termination, a label or a cable that was never right.

Then each sub-system on its own — displays, inputs, speakers, microphones, hearing assistance, control, conferencing, recording, network — and only then the whole room together: a long soak test, a power cut and restart, and a run through the functions the client was promised. Training, documents and the snag list come last, because they depend on everything before them.

Network details, without the passwords

Most rooms now have a control processor, displays, a DSP and a codec on the network. The form keeps a list of each device's hostname, IP address, MAC address and VLAN, because that is what the client's IT team will ask for the first time something drops off. It deliberately has no place for passwords. It records that default passwords were changed and that credentials went to the client by a secure route — never the credentials themselves.

Snags, acceptance and the re-test

Anything that is not right goes on the snag list with where it is, who will fix it and by when, and whether it blocks handover. The client's representative then accepts the room, accepts it with the snags listed, or asks for a re-test. In the ReportWalk app, Start a re-inspection turns every failed check into its own card for the return visit, so the re-test covers exactly what was wrong and shows it beside what you found the first time.

Common questions

Who should commission an AV system?

Usually the integrator's commissioning engineer, who did not install the room, with the client's representative or the AV consultant witnessing. On larger projects an independent consultant may repeat or witness the key tests. The form records who took part.

How long should a soak test run?

Long enough to show heat, power and network problems that do not appear in the first few minutes. Many specifications ask for 24 hours or more with the system on and sources playing. Record the hours actually run and anything that failed during it.

What sound levels should I measure?

At minimum the background noise in the empty room and the program and speech levels at a few listening positions, with a sound level meter on A-weighting. The targets come from the design or the specification; the form records what you measured and whether it met them.

Do I need a separate form for every room?

Yes, one room per form. The project details carry from one room to the next in the app, so a floor of identical meeting rooms goes quickly, and each room keeps its own snags and sign-off.

Can I record passwords on this checklist?

No, and the form says so. The report travels by email and sits in shared folders. It records that defaults were changed and credentials were handed over securely, which is what the client needs to know.

Does a hearing loop need its own test record?

Usually yes. Induction loops and other assistive listening systems are often tested against a specific standard with their own measurements. This form records that the system was tested across the seating and that the test record is attached, rather than replacing it.
