On the South Shore, our teams work in municipal halls, hotels, and corporate headquarters alike. SYNC Audiovisuel provides sound, lighting, and video for your events in Longueuil: audio equipment rentals, installation, on-site management, and a single point of contact from kickoff to teardown.
Audio equipment rentals. You run the show, we provide the gear. Tested equipment, connection guides, and delivery available upon request in Longueuil.
Turnkey service. We handle design, transport, installation, testing, event management, and teardown. This is the most popular option for organizations that do not have in-house technical resources.
Permanent installation. For a conference room, boardroom, community center, or multipurpose hall that needs a permanently integrated audio and video system: multi-room audio systems, screens, tabletop microphones, simplified control. We design, install, and document the entire setup.
Our entire inventory is checked before every outing. State-of-the-art equipment is useless if batteries are dead or a cable is faulty: reliability depends on this routine.

The success of an event often comes down to audio details. Our setups vary depending on the context:
conferences, training sessions, staff meetings, launches.
table microphones, intelligibility, recording, and webcasting.
voting, remote quorum, archiving.
multiple rooms, concurrent workshops.
stage sound reinforcement, monitors, lighting.
speeches, entertainment, atmosphere.
ceremony, speeches, music.
On the day of the event, problems almost always arise at the boundaries between suppliers: video sound that won't play, a screen placed where the lighting fixture glares off it, or a camera that didn't receive the audio signal. By entrusting everything to a single team, those boundaries disappear.
You have one point of contact, one technical plan, one control room, and one invoice. And if the program changes along the way—which happens at every event—adjustments are made in ten seconds between technicians rather than through three different phone calls.


Sound quality isn't just about the brand of speakers. It comes from proper sizing, placement, equalization, and the care put into every project. Our technicians have been working in this field for years—conferences, concerts, public sessions, cultural events—and this expertise is most evident when you don't notice a thing.
Our solutions also cover the visual side: colored lighting to dress up the room, projection, mobile control rooms, and recording studios for your content. Every type of event receives a custom configuration, never a cookie-cutter package.
From our workshop in Montreal, we cover Longueuil and the entire South Shore, including Brossard, as well as Laval, Montreal, and the Quebec City region.
