DEJONG showcase


DEJONG carries a broad range of high-level audio-visual equipment. We have everything from small office projectors to speaker systems with beam steering that can serve 1,000+ pax audiences at ease. We rent out to other av companies on a dry-hire base or to end-users or complete with installation and staffing if needed.

But we can also assist you with a total av-solution for your event. We can brainstorm with you when still in the concept phase, create 3d visualisations of concepts with staging and lighting. We also work closely with external content producers to create one complete visual spectacle. And although we are with a small team, we work with a reliant pool of the best freelancers available to secure our well-known high-quality of work.

We have almost all equipment to fulfil the audio-visual need in the smallest canteen to the biggest event venues ourselves but when we are short in numbers or specific equipment, we can rely on our world-wide network to help us. This assures you of the right equipment and a familiar team.

Online or hybrid

It is not always possible to travel and meet physically for whatever reason. And when we can't DEJONG is your partner to let your show go on. Way for 2020 we made Virtual Presence for speakers and visitors possible. We merged meetingrooms that were on different continents like it was one big congress hall without losing interaction with the public.

With the Covid pandemic we evolved our services to fully facilitate online congresses and meetings. And however we miss having crowded rooms, we surely saw and learned of the advantages of this meeting form.


Often we forget to take photos of the events we do, but we like to share some photos of the rare occassions we didn't...
