The Ministry of Higher Education’s new auditorium in Riyadh has benefitted from a high-tech audio and communication fit out thanks to integrators Khalid Est and audio-systems specialist RCF.
Khalid Est, which has been specialising in turn-key, auditorium AV projects for over 40 years, partnered with RCF to provide high speech intelligibility and full translation facilities at the venue.
The MOHE building is considered by many in the Kingdom to be one of the nation’s projects that heralds a new era in Saudi development and infrastructure.
Khalid Est won the hotly contest tender to lead the technical fit out of the 850-seat auditorium, which included the design, supply and integration of all audiovisual components.
The venue is designed to meet Saudi Arabia’s conservative gender stance – the ground level is for use by male guests only, and the upper balcony for ladies (with separate entrances provided for each level). Part of the A/V system design was to link the main auditorium with the Ministerial office (and other meeting rooms) within the building facility via a LAN — providing the possibility to communicate via internet broadband with other remote locations.
Khalid Est, which has competed over 100 auditorium projects, made the acoustic sound calculation and room measurements based on the latest RCF L2406 full range, highly intelligible, compact two-way speaker column arrays, with vertical controlled directivity. Designed for speech and music reproduction, the L2406 is suited for a variety of fixed applications where the architectural and acoustic constraints of an environment requires tight control of the vertical acoustic dispersion.
Handling the low end extension is an S4012 subwoofer, with system optimisation provided by an RCF DX4008 4-in/8 out digital loudspeaker management system. Supplying the power are RCF’s HC2000 2x 1000W Class H amplifier and HC1600 2 x 800W Class H amplifiers.
Khalid Est also installed translation and Polycom teleconferencing systems. For the former, the latest RCF FORUM 2000 simultaneous translation system environment this system were RCF digital radio transmission, a central conferencing processor, interpreter console and headphones, 100-channel simultaneous translation pocket receiver, stethoscope headphones and other accessories. The installation also makes use of RCF’s gooseneck electret mics and announcement amplifier.
Other components from the Italian manufacturer’s catalogue featuring in the installation include MX1822 14+2 universal input, 2+2 output mixer rack and PR4092 9-in/2-out preamp.
As for the A/V element of MOHE, which operates under Creston master control, this was implemented based on high definition visual setup with live digital recording.
“This was a challenging project in every respect,” said installation project team leader (and executive manager), Amer Alkhaldi, who was assisted by project manager, Dr. Engr. Mohammad Fouad. ”The installation called for high speech intelligibility and simultaneous translation facilities — and RCF’s perfectly matched components were able to facilitate this.”
