Audiovisual installation
for museums and exhibitionsSystems built for the work
GGS designs, integrates and installs audiovisual systems for museums, galleries, cultural institutions and exhibitions, connecting artistic intent with reliable technology and day-to-day operation. We work with artists, architects, curators and exhibition teams from Lisbon and Barcelona, and our involvement does not end with the supply of equipment.

Involved before the installation, not only at the end
GGS often joins an exhibition during pre-production. We work with architects, curators, artists, builders or contractors and exhibition teams on layouts and technical plans, the positions of projectors, displays, loudspeakers and equipment, how the AV systems integrate into the space, custom technical structures, and access and maintenance considerations.
The aim is that the technology is resolved with the exhibition design, rather than fitted around it at the last moment.
Audiovisual systems integration
GGS integrates projection, video, playback, multichannel audio and system programming into one working system, designed together with the exhibition and installed on site. This is end-to-end integration, not equipment supply: equipment can be hired for a project, but the design, installation, programming and follow-up are what make the system work.
Projection, video and playback
Projectors, displays and LED walls with playback systems, specified for the room, installed and aligned on site, as in the exhibition-wide implementation at Black Ancient Futures (MAAT): projection, sound, LED wall and programming.
Multichannel audio and sound systems
Loudspeakers and multichannel or networked audio systems, positioned together with the exhibition design and calibrated in the space.
Cabling, programming and calibration
Prototyping and cabling, system programming, projection alignment, sound calibration and final testing, so that the exhibition opens with the systems running as designed.
Custom technical structures
Mounts and structures made to the exhibition layout, such as the custom steel structures built for Black Ancient Futures.

From planning to the last day of the exhibition
Planning, technical development, integration, installation, programming, testing and commissioning. Once the exhibition opens, GGS maintains the systems through the exhibition period, with remote support and final dismantling where the project calls for them. At Black Ancient Futures this included maintenance throughout the exhibition (2024–2025).
Equipment can be hired for a project, and technical support is available on request.
