The auditorium at Patliputra Rail Parisar has been equipped with a comprehensive BA sound system designed for powerful, uniform and controlled audio coverage. Delta 915-20 LA long-throw line array modules handle the main audience coverage, complemented by Delta 915-40 LA near-field modules for closer seating areas. The Alpha Sub 428 S twin 18-inch passive subwoofers reinforce the system with strong and extended low-frequency performance.

BA XP 15H powered loudspeakers provide flexible reinforcement and monitoring, while Onyx 210 XTW IP64 outdoor coaxial speakers extend reliable audio coverage to suitable external areas. VS 106 T wooden cabinet speakers support distributed audio applications within the facility. In the amplifier room, the system is powered through BA 2 XM and 2 XS Class-H power amplifiers together with the Alpha Control 100 DSP amplifier. A Delta Mix 32.8 digital mixing console provides central control, while the Delta Drive 48X loudspeaker management processor enables precise system processing, routing and optimisation. Together, the complete solution delivers clarity, controlled coverage and dependable performance across a wide range of auditorium applications.

“The British Acoustics installation delivers excellent speech clarity and balanced sound throughout the auditorium. The system performs consistently across different programmes and events. We are very satisfied with its overall performance and reliability.” - Vijay Pratap Singh, System Integrator / Govt Contractor (Indian Railways), E Consultancy Services.
