Renkus-Heinz C Series delivers sound at Mahindra University auditorium

Mahindra University, private university in Hyderabad, Telangana, India, offers courses spanning engineering, law, media and design. An integral part of the campus is the Dr. APJ Abdul Kalam Auditorium, a multipurpose space developed as part of a wider campus expansion and used for events, musical performances, seminars and daily classroom lectures.

To support both teaching and cultural programming, the university installed a Renkus-Heinz C Series point source system. The design brings together two passive CX151B Complex Conic loudspeakers, ten compact, passive coaxial CX61B loudspeakers and ten DRS18-2B subwoofers, creating a full-range reinforcement solution that provides even coverage, controlled output and intelligibility throughout the 1,100-seat space.

System design and specification were led by Sriram B.R., Design Director at AV consultancy firm Sonics, with CMPPL responsible for integration. Alphatec, Renkus-Heinz’s local distributor, supported setup and commissioning, while Audio-Technica microphones improved voice capture and audience interaction. “Before the new system was installed, students had to share microphones during lectures and sessions, so improving voice reinforcement was an important consideration”, says Sriram.

“The auditorium is an enclosed, air-conditioned space with no windows, making acoustic control especially important”, he continues. “We worked closely with the architects to ensure loudspeaker placement met both acoustic and aesthetic requirements. By integrating the system around the stage and proscenium area, with key elements mounted high above the front of the stage, we were able to direct sound precisely into the raked seating area while maintaining clear front-to-back coverage and minimizing visual impact. The compact C Series form factor made this easier.”

Acoustic containment was also central to the design. “It was imperative that the sound stayed within the auditorium to avoid excessive sound spill”, says Narasa Raju, Manager at Tech Mahindra. “The new system ensures every note and every word can be heard clearly within the room, without leaking into surrounding areas of the campus.” System control is managed via Dante and a touch panel with presets, allowing university staff to operate the room. “Only a small amount of training was needed, and staff now benefit from smooth day-to-day operation”, Raju notes.

Beyond the loudspeaker system, the auditorium was equipped with a wider AV infrastructure, including wireless microphones, a pass-around microphone, mixing, DSP, switching, video systems, screens and cameras to support teaching, presentations and event production.

The auditorium remains future-ready, with the audio system providing a foundation for planned enhancements such as a large video wall. The university is also considering further development, including building two additional smaller halls. “Based on the performance of the auditorium system, we would definitely consider Renkus-Heinz again for future AV rollouts at the university”, says Raju.
