The Indian city of Dinhata is a major cultural hub in the state of West Bengal. As part of a recent major renovation, it was clear that a significant audio upgrade was needed to satisfy modern audience expectations. Because it hosts such a wide variety of events, the new system had to be versatile as well as high-quality and reliable.
Systems integrator, Consulting Technologies, chose a Yamaha system with a dual 2.1 and 5.1 channel setup. It is based on the MTX3 matrix processor, with the main stage PA comprising L-R pairs of flown passive CBR15 loudspeakers and two floor-mounted R118W subwoofers. When the system is used in 5.1 configuration, another CBR15 – flown in the center of the stage – is also used, together with six CBR12s, which are mounted along each side wall of the auditorium. The versatility of the CBR12 is highlighted by two more being used as stage monitors. The system is powered by six Yamaha PX series power amplifiers, with live productions mixed on a Yamaha MGP24X mixing console. It also features an RX-A870 AV receiver for playback of movies and other AV materials with the 5.1 setup. In addition, the sound is delivered to the green room by a PA2030a power amplifier and VXS8 speakers.
