Looking to update a decade-old AV installation, the Shri Ram School in Gurgaon, Delhi contacted system integration specialist AV Science and Technologies (AVST), one of India’s leading AV design and installation specialists. The 15-year-old company in turn called in Tannoy and Lab.gruppen to specify the sound reinforcement component.
“We were invited by the school to carry out a site survey, and put together an integrated AV solution for this auditorium,” explained Gopi Ram Malik of AVST. “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 AV 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 timeframe to design and execute the installation well without disturbing the planned events.
“We have worked together [with Tannoy and Lab.gruppen] on many projects,’ he added. “So when it came to executing a solution for a school which has a very high reputation, I could think only of involving these brands. It was extremely important we proposed the best and delivered when it came to their expectations and requirements. 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 problem wasn’t so much with the acoustics of the room, but the fact that the old system was out-dated,” said Binny Sharma, applications and support manager for Tannoy and Lab.gruppen. ‘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. Secondly, they had a problem with uniformity of coverage: the sound wasn’t the same at the front as at the back. There was an additional challenge here because the room is used in several different configurations. 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. “So we did some demos they were convinced by the parameters that we showed them and decided to go ahead with us.”
The system consists of a left and right cluster, each comprising two Tannoy VX15HP dual concentric loudspeakers and a VSX18DR 18in 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 AVST 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 also supplied by AVST included a Christie DWU600-G projector, Extron switchers, transmitters, receivers and distribution units and Kramer wall plate switcher/transmitter.
Sharma was in attendance during the school’s annual three-day event to ensure the new system functioned smoothly. “This is one of the most prestigious events they have during their school year, and is a mixed programme encompassing lectures, drama and an annual meeting,” he said. “Previously the school had rented in sound systems, so they were very happy that the new system was able to perform so well and stand up to all the different requirements of this inaugural event.”
