Producers see the bid. They see the engineering doc. They see the final invoice. They rarely see the four days of decisions, drawings, and walk-through that turn one of those documents into a working show. The audience sees ninety minutes of polished general session. The crew sees seventy-two hours of work.
This is the inside view of a typical LA corporate AV build. We're walking through a hypothetical 500-person tech summit at a DTLA conference venue — three speakers, three panels, a reception, no client names. The cadence, the crew calls, and the calls we make on the radio are the same on every summit-scale event we ship.
If you're a producer reading this to understand what your AV team actually does between brief and show, that's the point. If you're a junior tech reading this to learn the rhythm, that's the point too. Either way, the show looks easy at doors only because eighty hours of work happened before.
The event
A 500-person tech summit. One general session ballroom (P3.9 main wall, 16x9, two IMAG side screens). Two breakout rooms (8x4 ft P4.8 walls, single-source signal). Reception in the pre-function space with ambient audio and decorative lighting. Three keynote speakers, two panels, one fireside chat, and an evening reception.
Total scope on the bid: LED walls in three rooms, line array audio in the ballroom, point-source audio in the breakouts and pre-function, intelligent lighting in the ballroom, basic event wash in the breakouts, full content playback, redundant playback for the keynotes, and a 12-person on-site crew for show day. Load-in begins four days before doors. Strike completes by 2 AM the morning after.
Day minus four — final pre-production
Final pre-pro, content QC, gear test
Crew gathers at the warehouse for final pre-pro. The engineering doc has been locked for two weeks; today is the day everything on the doc gets touched and tested.
The 16x9 ft P3.9 ballroom wall gets built in the shop bay. Every panel powers on, every signal path gets verified, every redundant playback path gets switched live. Calibration files load. Color charts get shot against the wall to confirm Delta E under 3 on the test camera.
The client's keynote decks land in the content folder. Our content op opens each one in the playback environment, scrubs through every transition, and flags anything that doesn't render — embedded fonts that didn't ship, video files that aren't H.264, slides where the speaker notes accidentally got promoted to the wall. The client's deck team gets a punch list back inside two hours.
Line arrays roll out for an inventory walk. Every box gets a visual inspection, every flying point gets a load test, every wireless mic gets a frequency scan in our shop's RF survey rig. The wireless coordinator builds the show's frequency plan against the FCC database for LA on the show date — the third-party events at the venue's other ballrooms are checked for RF conflicts.
The lighting designer walks the LD plot against the rigging plan. Every fixture position gets a hang weight, every fixture gets a circuit assignment, every cue gets a dimmer or DMX address. The plot is what the show op programs from; the rigging plan is what loads onto the truck. They need to agree to the inch.
Shop foreman walks the truck call. Every case has a location on the truck (front of trailer, middle, back, side door access) and a load-in order tied to the run-of-show. The pack list goes to the dispatcher, who builds the load-out side of the run sheet — the same gear has to come off in the reverse order it went on.
The reason pre-pro takes four days is that this is the last day we can find problems cheaply. A missing font on a deck, an RF conflict, a panel that won't calibrate — all of these are five-minute fixes in the shop. The same problems on load-in day become two-hour fires that delay every downstream call.
Day minus three — truck pack and travel
Truck pack, content load to media servers, last RF check
Three trucks pack at the shop — one for LED, one for audio and lighting, one for staging and rigging. The LED truck is loaded first because it unloads first at the venue. Loaders work to the manifest; foreman initials every line as it goes on.
Content op loads finalized decks, video assets, and animation loops onto the main and backup playback servers. Both servers boot identical. The backup server gets manually switched into production for a 15-minute test, then switched back. We confirm hot-switch works before we leave the shop, not on show day.
The client's run-of-show document — exact slide order, exact transition cues, exact panelist names with title cards — lands in the content folder. Anything submitted later than this morning gets handled at the venue, but loading the bulk now means the venue load-in is a verification pass, not a build pass.
Wireless coordinator drives to the venue with a portable RF analyzer. He walks the ballroom, the breakouts, and the pre-function. He logs every active wireless frequency in the building (other tenants, venue staff comms, neighborhood interference). The show's frequency plan gets re-tuned to clear bands. This is a step many crews skip; it's also the step that prevents the most embarrassing problem at a corporate summit — the keynote speaker's lavalier dropping out at the worst possible moment.
Our production manager and our lead audio engineer walk the venue with the venue's operations lead. Power tap locations get confirmed. Freight elevator access windows get scheduled. The truck dock gate code gets confirmed. The fire marshal walk happens this afternoon and the venue has signed off on our rigging plan; that paperwork lives in the production manager's bag for the rest of the week.
The reason corporate AV crews use the same five or six DTLA venues over and over isn't laziness — it's logistics. The crew knows the dock height, the freight elevator capacity, the power tap locations, and the union steward by name. Same-week bookings work at venues where we've shipped twenty shows; same-week bookings at unfamiliar venues are roughly twice the load-in time because every system is new. For neighborhood-level context, see DTLA event production.
Day minus two — load-in begins
Trucks arrive, ballroom build starts
LED truck pulls up to the loading dock. Stagehand call starts at 07:00 — eight hands plus our LED lead and rigging lead. The crew is on radios from the moment the first case hits the floor.
Rigging crew flies the ballroom truss with CM Lodestar motors. The main LED wall position gets surveyed against the LD plot. Header truss goes up to motor-up height. Sub-truss for the side screen IMAG positions follows.
Panels go on the header truss in sequence. The lead checks every panel's calibration card before it locks into position; spares (5% of total panel count) stay at the foot of the wall. Power tails get terminated, signal cabling gets pulled to the FOH world.
Main wall powers on. Test patterns push. The content op runs through the keynote deck end-to-end, slide by slide, on the actual wall in the actual ballroom for the first time. Two small color shifts get noted — a brand orange that reads slightly red against the panel — and the calibration file gets re-tuned in the next 30 minutes.
Line arrays and subs roll in. Audio crew picks up where rigging finished. Line array goes up on the L and R truss positions, subs ground-stack at the lip of the stage. Cable runs to FOH.
Intelligent fixtures hang on the lighting truss. Conventionals position around the room. DMX runs to the lighting console. First power-on lights are static white at full output, then the LD programs the first looks in real time as the room comes up.
Crew wraps at 18:00. Cases get stacked out of pedestrian areas, kit gets covered. Overnight security at the venue is briefed on which rooms are active. The PM does a final walk-through and locks the ballroom doors.
Day minus one — tech rehearsal
Breakout build, audio tuning, full tech rehearsal
Second crew call starts in the breakout rooms — smaller walls, faster builds. P4.8 8x4 ft walls go up in roughly three hours per room. Single-source signal from a laptop, no IMAG, no fancy switching. The complexity is in the consistency: all three rooms (ballroom + two breakouts) need to read the same color, same brightness, same content scale.
System engineer runs system tune. Pink noise, sweeps, real-room measurement with Smaart. Line array gets time-aligned to the subs; the subs get phase-checked against the stage. The PA gets EQ'd to the room's actual response, not a generic preset. This step takes two and a half hours when it's done right.
LD programs cues against the run-of-show. Each keynote gets its own look — warm wash for the CEO, cool blue for the technical demo, full color for the panel reception. The LD's console runs every cue twice as a walk-through, marking notes for the show op.
RF coordinator distributes mic packs to the speakers' green room. Frequency plan is loaded into every pack. Line check on every channel — audio engineer at FOH confirms each mic comes up clean.
The client's production team arrives. We run the entire run-of-show — every speaker walks out, every deck advances, every IMAG camera switches, every audio cue fires. Two issues surface: a panelist's title card has a typo, and one speaker's intro music is six seconds longer than planned. Both get fixed in 15 minutes. Tech rehearsal is the cheapest place to find issues; nobody finds zero.
Show is on rails. Final crew dinner, briefing on tomorrow's show timing. Lead positions confirm their seats. Production manager confirms doors at 08:30 for keynote start at 09:00.
Show day — everything you bid for, in one push
Doors, keynotes, panels, reception, strike begins
Full crew at the venue. Everything that was on rails last night gets verified again — every mic, every IMAG camera, every wall, every cue. Coffee is the first item on the call sheet.
Pre-function audio comes up. Ambient lighting in the foyer activates. Registration desk powers on. Attendees start arriving 30 minutes ahead of keynote.
The CEO walks. The wall pushes the opening animation. The LD calls the first lighting cue. The audio engineer rides the lavalier. The IMAG director switches between the close-up and the wide. Show op on the radio: "stand by cue 14." A 90-minute keynote takes roughly 850 individual decisions to execute cleanly. The audience sees one smooth flow.
Four panelists, one moderator, one extra wireless mic for audience Q&A. The audio engineer pre-mixes between the panelists; the LD shifts to a softer wash. Side IMAG screens show the active speaker.
Breakouts run in parallel with lunch in the pre-function. Both breakout rooms are running their second sessions. The PM circulates between rooms.
Second keynote and the fireside chat run with the same crew positions. By now, the room has rhythm. Cues fire on time. The wall doesn't fault. The audio engineer's mix is sitting at the right level on the room and on the broadcast feed.
CEO returns for closing. Outro music plays. The room thanks the speakers. Lights come up to event wash.
Pre-function ambient audio shifts to reception playlist. Decorative lighting activates. The ballroom AV remains live for any post-event content the client wants to run.
Final guests exit. Crew rests for 90 minutes before strike begins. The hardest call of the night is from now until 02:00.
Strike — the night nobody photographs
De-rig, pack, load out
Smaller rooms come down first. P4.8 walls de-rig in 90 minutes per room. Cases pre-load at the dock for the morning truck.
Line arrays come down before lighting because the audio truss has to clear for the lighting truss motor-down. Cables coil, road cases stack, sub-truss lowers.
Conventional fixtures de-hang. Intelligent fixtures come down on motor. DMX runs unplug. Lighting truss lowers and de-rigs.
Panels come off the header truss in reverse order. Each panel gets a visual inspection before it goes back in case — pixel faults that surfaced during the show get marked for shop service. Header truss motors down. The wall that took eight hours to build comes down in two.
Trucks pack in reverse order — LED at the back, audio in the middle, staging and rigging in the front. PM walks the room one last time, confirms nothing is left behind, and signs the venue's release form. The freight elevator hits its last call.
Crew dismisses. Trucks roll back to the shop for unpack tomorrow morning. PM is the last to leave the venue.
The numbers — the part that doesn't show on stage
A 500-person LA corporate summit at this scope is roughly:
- Pre-production: 4 days, 4-person team on the production side, plus shop time on every cart that ships.
- Load-in: 2 days, 12-person field crew at peak, 3 trucks, 2 freight elevator calls per day.
- Show day: 12-person crew on-site for 16 hours.
- Strike: 5 hours, full crew, 1 truck call back to shop.
- Total field hours: roughly 360 person-hours across the build.
- Total radio calls: close to 2,400 from first call to final wrap.
- Total audience-visible problems: the goal is zero.
That last number is the one that defines whether the bid was worth it. Most of the work happens before doors open. By the time the CEO walks the keynote, the show should run on rails. The crew's job at that point is to keep it on rails — not to fix things, not to scramble, not to improvise.
This is why "cheap" AV bids are usually expensive bids. The work that doesn't show up — pre-pro, RF coordination, content QC, tech rehearsal — is the work that prevents the audience-visible problems. Skipping it saves a percentage of the bid and adds risk to the show. Producers who have run their first corporate event know this; producers who are running their first event learn it the hard way.

The cadence above is a 500-person summit at a known DTLA venue. Scale up or down:
1,500-person all-hands with broadcast. The pre-pro window stretches to seven days. Crew at peak runs 25 on-site. Two playback servers become four (broadcast feed lives on its own redundant pair). RF coordination becomes critical because broadcast cameras carry their own wireless, doubling the active frequency count in the room. Lead time from booking to event minimum: 4 weeks for clean engineering.
200-person fireside chat at a private venue. Pre-pro tightens to 2 days. One-day load-in. Crew at peak runs 6. Same content QC discipline, same RF coordination, same tech rehearsal — the show is smaller but the floor of competence is the same.
Multi-day conference (3 days). The build is identical; the strike happens once at the end. Crew stays on-site for the duration with floating shifts. Power and consumables (gels, tape, batteries) get budgeted against three days, not one.
Hybrid event with broadcast. Adds a broadcast control room, dedicated camera ops, and a streaming engineer. Pre-pro stretches; total bid is meaningfully higher; show day adds 4-6 broadcast roles. The walls and audio stay similar; the broadcast layer doubles complexity.
