Hong Kong, China (September 2014) – The Wong Tai Sin Temple in Hong Kong is a well-known shrine and major tourist attraction. The traditional Taoist temple is situated on four and a half acres with grounds that feature three memorial archways and beautiful gardens.
DinoTech Ltd was recently commissioned to design a new audio system that would provide intelligible paging and provide traditional background music throughout the interior and outdoor areas. They ultimately created a distributed audio system – 15 zones – that combines 70 One Systems 103IM, 108IM and 112IM direct weather loudspeakers.
Joey Chan, senior consultant with DinoTech explains that “the intent was to broadcast high quality background music or live event audio to selected areas indoors and out.”
The injection molded One Systems enclosures utilize a copolymer material developed for use in extremely harsh weather environments that offers a high degree of UV protection. The grille assembly is a 3-layer design optimized for acoustic transparency and protection from windblown particles and water.
The 103IM loudspeaker is loaded with a high-frequency driver coupled to an elliptical constant-directivity horn. Its 4-inch woofer delivers extended bandwidth response and superb performance. The end result is superior system intelligibility, good vocal range and exceptional music reproduction.
The high-performance 108IM and 112IM are loaded with 8-inch and 12-inch woofers respectively. The loudspeakers are ideal for direct-weather outdoor installations, as well as for indoor applications where high vocal intelligibility and good musical accuracy are required.
Both the 108IM and 112IM utilize One Systems patented ET driver technology. Both the ETS driver in the 108IM and the -1ET driver design in the 112Im have a unique “equivalent throat” design that allows its radiation pattern to be controlled by the phase plug’s summation plane, instead of the conventional “exit diameter” at the end of the driver’s structure. The ETS and ET-1 drivers have a pure titanium diaphragm and a close-spaced circumferential ring phase plug that insures extended high-frequency bandwidth.
The Wong Tai Sin Temple sound reinforcement system is powered by four Lab.gruppen C 28:4 amplifiers. A Biamp AudiaFLEX DSP audio platform monitors and controls the 15-zones.
