Tannoy and Lab.gruppen have worked together to provide a sound reinforcement
solution for the newly-redesigned auditorium at the Shri Ram School in Gurgaon,
Delhi. The private school needed to update its system, which was installed around a
decade ago. The installation, which was handled by system integration specialist AV
Science and Technologies, encompassed a complete new audio visual system. One
of India’s leading A/V design and installation specialists, the 15-year old company
provides a scalable service covering all aspects of a project from receipt of the
initial client brief, encompassing project design, system supply, installation,
integration and maintenance.

“We were invited by the school to carry out a site survey, and put together an
integrated A/V solution for this auditorium. The school briefed us about their
requirement for live sound, presentations, seminars, lectures, competitions and
annual functions. It was an existing structure with fine acoustics, and only the A/V
needed to be revamped. The Shri Ram School is one of the most popular schools in
the NCR (National Capital Region) and is very busy with events, so we were given a
very short time frame to design and execute the installation well without disturbing
the planned events.’

Sam Malik contacted Tannoy and Lab.gruppen to specify a system for the project.
“We have worked together on many projects,’ he explains. “We carried out an
initial site survey with them, and they put together a solution which included Tannoy
speakers and Lab.gruppen amplifiers. Furthermore, we did some EASE simulations
and presented our solution to the school management. Fortunately, they decided to
go with what we were proposing, and finally we bagged the project and installed the
complete system within a week.’

The applications and support manager for Tannoy and Lab.gruppen, Binny Sharma,
takes up the story. “The problem wasn’t so much with the acoustics of the room,
but the fact that the old system was out-dated,’ he says. “The auditorium is used
for multipurpose activities such as day-to-day lectures and dramas, and the sound
system was giving them some problems as it didn’t have good intelligibility. The
stage can expand for certain applications, and the seating on the ground floor level
isn’t fixed, so the new sound system needed to cater for the different scenarios the
hall can offer.’

Sharma worked out a system design using EASE acoustic simulation software. “The
school’s annual function was due to happen in a month and they needed a complete
revamp of their audio and video systems in that time,’ he continued.

The system comprises of a left and right cluster, each comprising two Tannoy
VX15HP dual concentric loudspeakers and a VSX18DR 18-inch subwoofer. Front-fill
is provided by four Tannoy VX8 dual concentric speakers, with two VX12s used for
the balcony area and two further VX12s used as stage monitors. The system is
driven by a combination of Lab.gruppen C48:4, C16:4, C28:4 and IPD1200
amplifiers, and system control is via two Tannoy VNET SC1 digital system
controllers. A control room, supplied by AV Science and Technologies with a
Soundcraft XL7ii 32-channel mixer and a Lexicon MX300 effects processor, has also
been installed with two Tannoy DVS 4t speakers powered by a Lab.gruppen E4:2
amp, and two further DVS 4ts have been installed into a green room. The company
also provided beyerdynamic Opus 669 and Opus 654 handheld and lapel/headworn
radio mic systems, plus a selection of beyerdynamic wired microphones. Video
equipment including a Christie DWU600-G projector, Extron switchers, transmitters,
receivers and distribution units and Kramer VGA with audio and HDMI plate was
also supplied by AV Science and Technologies.
