A conference, gala, or general meeting is judged first by what the audience hears. If the back row can't understand the speaker, the content is lost. SYNC Audiovisuel designs, installs, and operates sound systems for your events in Montreal: audio systems calibrated for the room, reliable wireless microphones, and a control booth managed by a technician from start to finish. No equipment just dropped in a corner—we provide full service from kickoff to teardown.
No two rooms of the same size sound the same. A glass-walled hall, a low ceiling, a mezzanine, or 300 upholstered chairs completely change how sound behaves. That’s why we always start with the venue and the program before talking about equipment.
Depending on the configuration, we deploy:
The entire chain is tested before doors open: levels, feedback-prone frequencies, battery life, and backup plans for every critical microphone. Sound quality isn't improvised on the day of the event; it’s prepared.

Most projects go beyond just sound. A panel discussion needs a readable screen, a gala requires stage lighting that highlights the performers, and an AGM needs recording and webcasting for remote members. Entrusting audio to one provider, video to another, and rigging to a third only creates more gray areas on the big day.
At SYNC, sound, lighting, and video projection are delivered by the same team, with a single point of contact. One technical plan, one control booth, and one person accountable to you. This is also what allows us to perfectly synchronize a video triggered from the booth with the host's microphone and a lighting cue, with zero downtime.

We primarily work with organizations that cannot afford any mistakes in front of their audience:
multiple rooms in parallel, simultaneous workshops, and Q&A sessions with roving microphones.
speeches, awards ceremonies, musical performances, and background audio between segments.
table microphones, voting, maximum intelligibility, and session archiving.
message enhancement, soundtracks, and seamless transitions.
voice capture for both in-person and online participants.
one mix for the room, another for the web stream, because they aren't the same ears.
Whether the event is held in a downtown hotel, a convention center, a corporate boardroom, or an unconventional space, the logic remains the same: technical site visit, adapted plan, team on-site.
Some clients already have a stage manager and are only looking to rent high-quality audio equipment. Others want us to handle everything. Both are possible.
With our turnkey service, our range of audio equipment is delivered, installed, tested, and operated by a technician who stays at the console during the event. With a simple rental, the equipment is checked, documented, and ready to plug in. In both cases, you know exactly what you are getting and at what price: our quote is detailed, line by line, with no surprises at teardown.


Our technicians always start by listening to the room. A venue's acoustics—reverberation, glass surfaces, ceiling height—dictate the choice of products and speaker placement far more than the equipment's spec sheet. A highly reverberant room requires more directional systems, less power, and precise equalization; a dead room requires the opposite.
This is where our expertise comes into play: our team has a combined 30 years of experience in corporate events across Quebec and Canada, using cutting-edge technology that is maintained and checked before every outing. Details matter—a questionable cable or a weak battery is enough to ruin a speech.
Based at 9412 Boulevard du Golf, in Saint-Léonard, Montreal, we operate throughout the island as well as in Laval, Longueuil, Brossard, and the Quebec City region. Proximity matters: it allows for an advance site visit and ensures our team arrives with time to spare rather than in a rush.
Beyond sound reinforcement, we offer complete audiovisual solutions: stage and architectural lighting, large-format video display and projection, LED walls, multi-camera capture, webcasting, and studio or on-site recording. These professional services are designed to work together to create cohesive experiences for your audience, both in-person and online.
