From microphone to LED screen

In-room technology for congresses:
sound, vision and lighting

The technology doing the work in the room

A congress depends on technology nobody notices. The back row hears the speaker as clearly as the front, the presentation is readable from every seat and the stage looks as though it had always been there. Behind that ease lie dozens of decisions: which microphone type suits a panel discussion, how much brightness a projector needs in a room with daylight, and where to place the control position so the technician can see both stage and audience. IFS Audiovisueel has been making those decisions since 1962, together with you and tailored to your venue, your programme and your audience. Below you will find what congress technology involves: sound, vision and lighting, and what to look out for.

Every choice explained, every detail arranged.

Frequently asked questions

Which microphones are suitable for a congress?

That depends on who is speaking and how the programme runs. A lapel microphone or headset gives the speaker freedom of movement and a constant level, even when they turn towards the screen. A lectern microphone suits a formal programme with a fixed speaking position. For questions from the floor, wireless handheld microphones work fastest, supplemented by a throwable microphone in large rooms. For panels and meetings we use discussion units with a talk button, so the floor is shared in an orderly way. In practice we combine these types within a single congress. What matters is that all wireless microphones run on free, mutually separated frequencies; we establish and programme that in advance.

Projector or LED screen: which should I choose?

A projector is more economical for a large image area and works excellently in a room that can be dimmed. An LED screen stays bright under daylight and strong stage lighting, needs no throw distance and delivers a deeper, higher-contrast image, which makes it the better choice in rooms with many windows, low ceilings or a busy stage. Viewing distance counts too: the further back the last row, the larger the image needs to be. We calculate this in advance from the floor plan of the room and advise which solution fits your programme and budget.

How does presentation management work during a congress?

We prefer to collect all presentations and videos a day in advance. We load them centrally onto one system, check layout, fonts and aspect ratio, and test the videos for sound. During the congress the technician plays the right presentation from the control position and switches between slides, video and camera. The speaker advances their own slides with a presenter and sees them again on a confidence monitor. That way there is no shuffling of laptops and cables between speakers and you lose no time between sessions. Late changes are no problem; we process them up to just before the start.

How many technicians does a congress day need?

For a compact meeting with sound, a projector and one speaker, a single technician is often enough. As soon as multiple cameras, a livestream, parallel sessions or interpreting equipment are involved, we work with a team in which everyone has their own task: sound, vision and vision mixing. With several rooms running at once we assign a technician per room, plus a project manager who oversees the whole and is the point of contact for you and for the venue. Our technicians arrive in suits, equipped with laptop and service case, and stay for the whole day.

How far in advance should congress technology be arranged?

For a standard set-up in a familiar room, a few weeks ahead is usually enough. For a large or multi-day congress, parallel sessions, a livestream or interpreter booths, we prefer to plan several months ahead, certainly around the busy periods in spring and autumn. We are happy to visit the venue beforehand to determine sightlines, power, rigging points and the place of the control position. We are also glad to think along at short notice; let us know and we will see what is possible.
