Puncak Alam Mosque marks first TOA steerable array deployment
MALAYSIA: Funded and owned by prominent Malaysian businessman and water tycoon, Tan Sri Rozali Ismail, the 5,000 capacity Masjid Puncak Alam, has been attempting to stake its claim as the country’s most iconic new mosque. Malaysian mosque sound specialists Acousticon, in collaboration with acoustic consultancy Juru & Teras Bersekutu Sdn Bhd, were enlisted by the management to overcome the acoustic issues found in its main and open prayer halls.
The mosque required a sound reinforcement system that could provide high-quality audio into the worship spaces. As the system would be operated by non-technical employees with minimum oversight, it was also critical that the system was simple to use.
Acousticon opted for a steerable line array to help minimise internal room reflections. Marking the their first real-world installation, TOA SR-D8 enclosures were selected, with two clusters installed in front of the Kibla wall and mounted 3m from the floor to cover the entire main hall. Each cluster consists of a master and slave unit wired back to the control room via a Cat-5 cable and steerable over a Wi-Fi connection. This was a big factor governing selection of the system as it cut down the setup time dramatically.
‘The two main arrays produce consistent sound pressure levels, only varying by 2dB with distance from the speaker,’ says Azizi Ala, technical director of Acousticon Sdn Bhd.
Away from the steerable solution, a further 38 TOA F-2352SC coaxial ceiling speakers were installed under the balcony and first floor areas to extend coverage for female worshippers. Added to this, six TOA DH-120s have been installed 35m up the mosque’s minaret for call to prayer.
In addition to the speaker system a TOA D-901 digital audio mixer is used to combine feeds from 10 different microphone sources located throughout the building. These include an AKG CK97 lavalier condenser microphone, AKG GN series gooseneck mic, Sennheiser e825s and a Sennheiser EW100 G3 series wireless microphone system.
Biamp’s AudiaFlex serves as the speaker processor and matrix processor for 16 output zones, and a total of 10 TOA DA-250D digital amplifiers provide power the whole system. On top of that, Biamp’s RED-1 control panels have been installed in the equipment rack to control speaker coverage, zone output levels and microphone input levels.
Away from the main hall, the 2,500-capacity open prayer area was also equipped with TOA loudspeakers. A total of 30 TZ-S60Z enclosures – designed to minimise echoing – were installed in multiple rows in the open area.
‘We are so proud to be the first installer in the world for TOA SR-D8 and Puncak Alam Mosque will be the first reference for it,’ concludes Mr Ala. ‘Steerable speaker technology is not widely used in Malaysia because of the premium price, but we do hope that this kind of speaker will rise in demand soon as it provides great quality and flexible control for clients. According to Tan Sri Rozali, the system installed is easy to operate and the sound quality is clear through the mosque.’
