When Qatar Olympic Committee (QOC) drafted in the services AV-TECH to re-purpose its 100-seat auditorium in Doha, converting it into a multipurpose space for conferencing and multimedia presentation.
The auditorium will be used for a vast range of functions — from committee meetings to press briefings. Having designed a 5.1 surround sound environment, using modelling equipment to counter the reverberation time, the integrators specified Christie’s 3-chip DLP DS+8K 8500 ANSI lumens SXGA+ projector.
AV-TECH system engineer, Kiran Dias, ripped out the old infrastructure and ceiling-mounted the new projector on a motorised recessed lift.
Fitted with a long-throw lens the projector needed to cover the vast 3.5m x 8.5m Da-Lite screen with corner to corner consistency in 16:9 aspect ratio, taking data. The projector takes multiple feeds from PC and laptop, as well as a professional Tascam DVD player and interactive whiteboard inputs. Source select and routing is handled by an Extron switcher.
The whole system is under the master control of an AMX MVP-8400i 8.4" Modero touch panel.
"The installation was very straightforward," summarised Dias. "The clients are very happy with the result and delighted with the performance of the projector."
As for their audio solution AV-TECH turned to a Meyer active solution using their proprietary Galileo 616 for the speaker management system.
The signal path shows that the AV signals pass through a Lexicon MV-5 cinema processor — the video is then split to the Extron video switcher while the audio analogue signal passed through the Galileo 616. The system also utilises a Beyerdynamic Multilanguage conference system and the conference audio is fed to the main Soundcraft audio mixer.
"We have managed to deliver a single piece of integrated art in terms of the audio-visual technologies, and this is designed to serve QOC's high calibre events," concluded Hadi Arzouni, general manager of AV-Tech.
