Commercial Audio Commissioning Checklist: What to Test Before Handover
A commissioning checklist for commercial audio handover: zone walk-downs, tap and load records, intelligibility tests, presets and the documents to leave behind.
Commissioning is the hour that decides whether a commercial audio system is remembered as effortless or as a support ticket generator. Everything was installed and wired, but only commissioning proves the system does its job in the real room, with real program, at real levels — and only the paperwork from that hour protects both parties afterward. This checklist covers what to test and what to write down before anyone signs.
Walk every zone with real program at real level
Test tones verify wiring; program material verifies the system. Walk each zone playing the kind of content it will actually carry — a spoken announcement in a corridor, dinner music in the restaurant end, a lectern microphone in the meeting room — at the levels the client will actually use. Listen from the seats people occupy, not from the doorway, and note every position where coverage falls short or speech turns glassy. Placement fixes made today cost minutes; the same fixes after sign-over cost a return visit.
Record taps, loads and levels
On distributed lines, write down the tap position of every speaker and the measured or calculated line load per zone, alongside amplifier gain settings — the tap and load logic our 100V tap guide explains (https://joyceaudio.com/posts/100v-speaker-tap-power-explained). This sheet is the system's identity document: it lets the next contractor add speakers without overloading the line, and it turns a future dead zone from a mystery into a comparison. Photograph the amplifier panel and the routing settings as well; labels fall off, photos do not.
Test the jobs the room will actually do
Beyond coverage, test the specific duties. For speech rooms, that is an intelligibility check from the farthest seat with a real talker, not a test disc. For rooms with microphones, a feedback walk-down at working gain, following the geometry rules in our troubleshooting guide (https://joyceaudio.com/posts/conference-speaker-microphone-feedback-fix). For call-enabled rooms, a live call test in both directions. For multi-format halls, a preset recall of each saved scene. A system that passes coverage but fails its actual duty is not commissioned yet.
Leave documents, not goodwill
The handover pack is part of the install: the commissioning sheet with taps and loads, the preset list and any passwords transferred to the client's custody, the as-built cable routes where they differ from plan, warranty terms in writing, and the contact for claims — the questions our warranty guide lists (https://joyceaudio.com/posts/speaker-warranty-and-spares-policy) tell you what that document should contain. Hand the pack to a named person and demonstrate the one or two controls the client's staff will actually touch day to day.
FAQ
Who should attend commissioning?
The installer's lead technician and the client's named system owner, at minimum. The client's representative should hear the walk-down tests with their own ears and sign the sheet on site, because acceptance witnessed is acceptance understood.
The client wants to change levels after a week. Is that normal?
Yes, and it is better done with the commissioning sheet in hand: adjust against the recorded baseline so the change is deliberate, then note it. Unrecorded tweaks are how documented systems drift into undocumented ones.
Our team supports commissioning for projects using our speakers and amplifiers: send the zone plan and schedule, and we will join the walk-down by video call, then supply the commissioning sheet template and warranty terms in writing as part of the handover pack.
