CAMP – Center for Architecture and Metropolitan Planning


Prague Institute of Planning and Developement has launched a unique project – CAMP (Center for Architecture and Metropolitan Planning). It is a information center and its main part is a modern multifuntional hall where territorial developement of Prague is presented and discussed. For this purpose, an exhibition hall with a unique large-scale projection, a modern lecture hall, a meeting room and other associated spaces are used. We have taken care of the entire room acoustics and sound system of these spaces, including the media system.

Large-screen projection powered by the best media server on the market

In the CAMP exhibition hall, a unique interactive projection on a 25meter wide wall takes place. We have integrated d3 4×2pro media server that takes care of image blending from all three projectors. This server allows rendering video and 3D objects in real-time and displaying  projections with very high resolution.

Same technique is being used in many world-renowned theaters, also by creators of video mapping and by music stars in their shows (The Rolling Stones, U2, Beyoncé, Lady Gaga or Robbie Williams).


How have we solved room acoustics and sound system?

  • We have designed an even distribution of acoustic elements in the space to avoid unwanted sound reflections such as echo or fluttering echo, and on the contrary, to produce the desired sound reflections, especially if the sound source is a person.
  • We have designed ceiling tiles from two types of acoustic absorbers for absorption of different freqencies.
  • All acoustic elements have been designed in accordance with the architectural design of the interior.
  • The sound system of the lecture hall is solved by using loudspeakers with a narrow coverage which minimizes the disturbance of the main exhibition hall (the sound is directed straight to the viewers of presentation).

Technical Specification

Media System

The core of the whole media system is a d3 4×2pro media server from a company d3 technologies (now disguise). It allows video and 3D objects rendering in real-time and projections with very high resolution. For the presentational hall, there is professional modular Oppo Blu-ray Transport player with HDBaseT output installed and a multichannel 7.1 audio.

AV signal distribution is managed by Extron DXP 44 HD 4K matrix switcher with 4 HDMI outputs and inputs. There are also installed two Extron HDMI 4K 230 Rx DTP receivers for HDMI.

Sound System

For the exhibition hall, we have designed and integrated the sound system by four JBL Control 67 HC/T high ceiling pendand speakers. Thanks to the radiation angle of 75 °, they are ideal for the improvement of voice intelligibility and musical clarity in this room. In the lecture hall, where auditorium with elevated stands is located, is installed 7.1 sound system. It consist of JBL Control CRV two-way loudspeakers and a JBL Control SB-2 subwoofer.

For the optimalization of the audio system and the possibility to switch into different zones and the volume control, a modular audio BSS BLU-100 processor with extended outputs and inputs was designed. A pair of external panels (communication via LAN) was installed in terms of control.

The source of the audio signal can be either a laptop (a double input cable access points with Extron UTP transmitter for a high-quality signal transmission over a long distance) or six  Sennheiser handheld wireless microphones. Connecting the inputs and individual sound zones can be done in a fully configurable audio processor.
