Taking sound to overflow crowds

THAILAND: Wat Tha Sung, also known as Chantharam Temple, is an historic edifice situated in the northern province of Uthai Thani, 200km from Bangkok. This golden temple was built during the Ayutthaya period (1351 to 1767). Every year, the temple attracts many visitors who travel to admire its beauty, pray and listen to sermons.

To cope with the increasing number of visitors, the temple developed an outdoor gathering area in front of the Golden Castle to host the thousands of believers that flock to attend the sermons. A loudspeaker system upgrade was needed to provide highly intelligible sound to these outdoor crowds. With product quality and reliability factored in, along with pre- and post-sales support, the project was entrusted to Bosch-certified partner, Vision One, to supply and install the entire project with equipment from Electro-Voice (EV).

At the design stage, Electro-Voice and Vision One visited the temple to conduct an on-site acoustic simulation test. EV’s small-format, high-output, powered ZX1 loudspeaker, designed for weather resistance, was selected as the centrepiece of the system. Compact Evid models from EV cater to crowds that convene in the parking area; an EVF horn-loaded loudspeaker was installed in front of the Golden Castle. All speakers were powered and processed by EV technology: two CPS amplifiers, a Dx46 FIR-drive processor, and a NetMax N8000 system controller. After the installation, the team conducted the final sound check to reaffirm that the actual sound production matched the predicted simulation.

Visitors to the temple are claimed to have commented that the audio is now crystal clear and ‘like a sound from heaven’.
