DOHA, Qatar- 19 May, 2015:
In what has been one of the largest and most complex wireless audio
systems deployments in the Middle East, the Sheraton Doha, an iconic 5
star hotel in the capital of Qatar, has successfully leveraged
Sennheiser's solutions to roll out a state-of-the-art wireless
conference and translation system across its entire meeting and
conferencing facilities. The landmark project, which was handled by the
DOUMMAR Group, ensures that the Sheraton Doha can continue to offer the
very best event, meeting and conference facilities to its customers.
“The
Sheraton Doha spared no expense and every system that has been utilized
is absolutely first class,” said Esber Nasrallah, operations manager
for Q2 Advanced Technology Contracting LLC, a member of the DOUMMAR Group of companies, which
handled the entire AV portion of the hotel's renovation. “It was
decided to use wireless systems in order to deliver maximum flexibility
in terms of mobility, portability and scale. The hotel wanted to be able
to add or remove microphones and receivers effortlessly across the
twelve expansive conference rooms as per guests’ requirements.”
Besides
the challenge of accommodating over 200 channels into the UHF spectrum
while avoiding intermodulation and interference, the team had to
convince the regulatory authority in Qatar that it would not operate in
certain frequency bands. The meticulous planning required to accomplish
these tasks was aided by a specialized software called Sennheiser
Intermodulation Frequency Management (SIFM) which allowed the team to
input the frequency ranges and receive a detailed frequency distribution
plan for the building. As there is no frequency overlapping of
channels, Sheraton Doha can move transmitters about for portability
without concerns of intermodulation and interference. The stringent
wireless security requirements were overcome by a combination of
Sennheiser's proprietary signal encoding and industry-standard 128-bit
AES encryption.
The
project saw the deployment of 120 Sennheiser 3000/5000 Series
microphones with Neumann KK-104 capsules - a combination used by many of
the world's most famous music artists. Also utilized were 400 ADN-W
wireless delegate units for the portable conferencing systems, as well
as 4000 Sennheiser HDE-2020 receivers and 21 SR-2020 transmitters for
the translations systems - representing the largest and second largest
global deployments for the Sennheiser conference and translation systems
respectively.
Perhaps most impressively, Q2 Advanced Technology Contracting LLC
and Sennheiser Middle East managed to plan, supply, commission and test
all these systems in a short five month timeframe. “We flew in experts
from our headquarters in Germany and scaled our production to meet the
project demands. Even with the extremely tight deadlines, we did not
compromise on quality and attention to detail. We have received no
negative feedback on the installation and no calls to assist or remedy
any defect in the installation. This is despite the fact that the system
is being used for daily events at the iconic venue, which I believe is
best testament to the quality of the systems and the implementation,”
concluded Ryan Burr, Technical Sales Manager for Sennheiser Middle East.
Mr
Jean A. Doummar CEO of the Group stated, "The success of our endeavour
at the Sheraton is the result of a quality centric management team and
spirit and a tight collaboration between our partner Sennheiser, our
back office in Beirut and front office is Doha, orchestrated and led by
our Operations Manager Mr. Esber Nasrallah."
