Quick answer: For a 250–350 guest prom or formal event in a large, wide ballroom like the Pan Pacific Hotel Vancouver, Vancouver Projector Rentals recommends dual 8,000-lumen projectors rear-projected onto two 144″ x 81″ fast-fold screens, mounted on aluminum truss to keep hardware off the dance floor, paired with four JBL EON 715 speakers and two JBL EON 718S subwoofers for even audio coverage, plus wireless rechargeable parcan uplighting and an on-site AV technician for the whole night.
Grad season means one shot to get it right. There’s no second night to fix a blown speaker or a screen the back tables can’t see. When North Delta Secondary’s grad committee booked the ballroom at the Pan Pacific Hotel Vancouver for their 2026 prom, they needed an AV partner who could scale sound and video across a large, formal room without the setup becoming a distraction from the night itself.
The Challenge: One Screen Isn’t Enough for a Wide Ballroom
The Pan Pacific’s ballroom is a showpiece space, with cascading crystal-chain chandeliers and a wide, open floor plan seating hundreds of guests across long rows of round tables. That layout is exactly what makes single-screen setups fail: guests on the far sides or near the back simply can’t see a screen placed at one end of the room. The head table, podium, and DJ booth also needed to stay clear of stands and cable clutter, since the same floor doubles as the dance floor once the program wraps up.
The brief was specific: cover the room visually and audibly end to end, keep equipment out from underfoot, and run two screens in perfect sync so no table misses the slideshow, grad video, or speeches.
The Vancouver Projector Rentals Solution
To match the scale of the Pan Pacific ballroom, we built a symmetrical, dual-screen AV package:
Dual high-brightness projection. We deployed two 8,000-lumen projectors, one per screen, configured for rear projection so the units sat behind the screens rather than in the aisles. That kept sightlines clear and eliminated the shadows a front-projection setup would have cast as guests and staff moved through the room.
Two large-format screens, positioned symmetrically. On either side of the stage, we installed matching 144″ x 81″ fast-fold screens finished with black dress kits, giving both sides of the ballroom an identical, clean sightline without a single table left looking at an angle.
Elevated, off-floor rigging. Each projector was mounted on a 2-meter aluminum truss system secured to heavy steel base plates, keeping cables and units off the ground where hundreds of students would later be dancing.
Full-room audio coverage. Four JBL EON 715 speakers paired with two JBL EON 718S subwoofers ran through a multi-channel analog mixer, giving speeches, music, and video sound even, balanced coverage from the head table to the back wall.
Synced video, zero lag. HDMI signal distribution mirrored the live feed across both screens simultaneously, so slideshows and the grad video stayed perfectly in sync no matter which screen a table faced.
Ambient, cable-free lighting. Rechargeable parcan lights added warm uplighting around the room’s perimeter without a single power cable to trip over, complementing the ballroom’s chandeliers rather than competing with them.
Delivery and On-Site Technician Support
Coordinating AV for a major downtown hotel means working around loading-bay schedules and tight turnaround windows. Our crew delivered directly to the Pan Pacific’s loading bay, then completed full assembly, cable routing, and signal testing on both screens before doors opened. Throughout the ceremony, an AV technician stayed at the control table monitoring the audio mix and video feed, ready to react the moment anything needed adjusting. Once the last dance ended, our teardown crew cleared the stage and floor so the venue could reset for its next event.
Why It Worked
A prom doesn’t get a retake. By mirroring the projector-and-screen setup on both sides of the room, keeping cables and rigging off the dance floor, and staffing a technician for the full night, the AV supported the event instead of interrupting it. It’s the same standard of coordination we bring through our full event production services for graduations, formals, and school events across Vancouver.
Sizing Guide for Your Own Prom or Formal Event
- Under 100 guests, single small room: one 3,500–5,000 lumen projector with one fast-fold or tripod screen and two speakers usually covers the room.
- 100–250 guests, one ballroom: step up to a single 5,000–8,000 lumen projector on a large fast-fold screen, with four speakers and a subwoofer.
- 250+ guests or a wide ballroom like the Pan Pacific: a dual-projector, dual-screen setup on truss risers, matched with four-plus speakers and dual subwoofers, is the safer call.
Frequently Asked Questions
How many projectors does a large prom or gala need? For ballrooms wider than roughly 60 feet, or rooms seating 250+ guests, two projectors on two screens on opposite sides of the stage ensure every table has a clear sightline.
What is rear projection, and why use it for a school event? Rear projection places the projector behind the screen instead of in front of it, freeing up floor space near the stage and preventing shadows from guests or staff walking past.
How much sound coverage does a 300-person ballroom need? Four full-range speakers with at least one, ideally two, subwoofers through a multi-channel mixer typically provides even coverage for speeches, video sound, and dance music.
Does Vancouver Projector Rentals provide technicians for prom nights? Yes. Every large-format rental includes delivery, on-site calibration, and a technician who monitors sound and video for the duration of the event, plus teardown afterward.
