The university was reportedly never satisfied with the way the audio setup in its old auditorium sounded. For the new venue, audio became a top priority and the project specification called for a solution that could cover the lower seating areas and upper balcony as well as two separate VIP rooms.
A total of eight RoomMatch line array loudspeakers wee installed along with a pair of RMS215 subwoofers, three PowerMatch PM8500 amplifiers and an ESP880 processor. Control is via Midas M32 and M32R digital mixers located in two FOH positions: near the stage area and in main control room on the upper balcony respectively. A Midas DL16 stagebox completes the setup.
The room seats 5,000 students and faculty members and is 50m deep x 40m wide with a ceiling height of 10m. This volume, coupled with the balcony and an array hard surfaces resulted in high reverberation. To combat this, the PT Prima Audio team recommended acoustic treatment, which was also carried out by SOF_AudioMinistry. Mineral fibre and wood paneling were fitted to all four walls and a blend of panels and wide contours were installed around the ceiling edges. This brought the reverberation time down to 1.8s.
Following the installation, the university’s founder, Mr Darsono, is pleased with the sound quality in the new auditorium. ‘The sound is warm and clear, with a proper acoustic design,’ he said. (https://www.proavl-asia.com/?RID=kvJQOC0uEg)
