L-Acoustics- The sound of bliss at Sri Sathya Sai Premamrutham


The Sri Sathya Sai Premamrutham, nestled admits the picturesque hilly backdrop is a magnificent architectural edifice and hallmark of devotion towards Sri Sathya Sai Baba. This auditorium cum prayer hall, which is inspired by European classical architecture can seat around 10,000 people.

The auditorium needed a sound system that could blend into the exquisite architecture and would guarantee quality no matter what the location. This is where leading Delhi-based Pro AV Company Hi-Tech Audio Systems Pvt. Ltd comes to the picture who were given the responsibility to supply, design and install the PA system at Sri Sathya Sai Premamrutham. Since past 25 Glorious years, Hi-Tech Audio Systems Pvt. Ltd. is a name reckoned with quality, commitment and service par excellence.

Bharat Kumar, Project Manager, Sri Sathya Sai Premamrutham shares, “For the management the project is a milestone to accomplish. We have invested our time and money to provide the best to the devotees. With such ambitious project, the technical audio install had to be taken into prime consideration in order to create a spiritual ambience. The task of installing the PA speakers in the auditorium was entrusted to Hi-Tech Audio Systems. The Company has a vast profile of projects under its banner and two decades of unmatched experience in the audio-video industry.”

“To maximize clarity in speech and music reinforcement, the client needed something that would be very clear, plus be focused to put the sound exactly wherever it is needed in the auditorium. We went forward with L-Acoustics which is based on a “full system” approach including all enclosures, rigging, amplification, and DSP for the system. These results in a highly predictive, standard system with control and monitoring that satisfies the performance requirements of the venue,” explains Rajan Gupta, Managing Director, Hi-Tech Audio Systems. He adds, “Being the India distributor for L-Acoustics, we wanted to provide consistent audio quality and the best to our client. We have collaborated with Bengaluru based audio rental J Davis Prosound & Lighting to integrate and install the audio system for the venue.”

Hi-Tech’s Senior Application Engineer, Kallol Nath says, “From the pre-installation stage onwards, experts from

L-Acoustics, Paris were involved in this project. They have designed the entire system installation in SOUNDVISION, the 3D sound system design program capable of operating in real time. This has helped us a lot to implement the installation in the venue as we had a clear picture about the sound flow across the auditorium.” Kallol continues, “The inventory includes six KARAi per side for main PA left and right along with three SB18i arranged in cardio pattern for main PA subs. Since the venue is enormous in size, we have also installed four KARAi per side delayed stacks and two SB18i per side for delayed subs. The venue was a highly reflective zone with high reverberation time. This was the biggest challenge as we have to provide direct sound to the congregants who visit the auditorium. Thus we have integrated the system in such a way that we get a clean, natural sound throughout the prayer hall. In addition to the above mentioned systems, we have also installed eight 5XT in front-fills and two X12 for tackling the side-fills which is directly under the main PA and at a close vicinity to the stage. The entire installation is amplified through LA4X. I know that nothing comes easy in our profession but with L-Acoustics the end result is always marvelous and now the devotees can experience the tranquil sound in Sri Sathya Sai Premamrutham.”

“It was a pleasure for me to work with the team at Hi-Tech Audio Systems and J Davis,” says Germain Simon, Applications Engineer at L-Acoustics. “Together, we were able to propose a solution that provides pristine sound to deliver a clear message all across this holy venue, while blending into the exceptional architecture. The new KARAi system has solved acoustical issues from the challenging shape of the hall and some of the reflective doors and glass architectural elements and I’m proud to have been able to help the audience at Sri Sathya Sai Premamrutham enjoy a better worship experience.”

Bharat says. “Team Hi-Tech Audio along with L-Acoustics experts has done an excellent job in the design and installation of the PA speakers in the venue. Considering the fact that the acoustics of the auditorium had high reverberation time, the team has achieved very precise sound and music.”

In-house Sound Engineer Pradeep explains, “L-Acoustics systems are renowned for their uniform, full-range, natural sound. Clear, intelligible and powerful sound now reaches to the very last row of the seating area. Moreover the professional support and technical expertise provided by team Hi-Tech is outstanding.”
