Local audio company Farasout Negar has completed the design and installation of a PA system for calling Muslims to prayer at the Imam Mousa Kazim Holy Shrine in Kazmein, Iraq.
To achieve 360 degree coverage and very high SPLs, Farasout Negar designed a system based on sixteen Community RSH-462 exponential FocusedArray horn systems. Each RSH-462 utilizes four Community M200 ferrofluid-cooled compression drivers mounted to a hand-laminated, reinforced composite fibreglass horn-array with a 60-degree horizontal and 20-degree vertical coverage pattern. With a sensitivity of 117dB for 1W at 1 metre and a 750W program power handling capacity, the RSH-462 provided the considerable SPL required.
Coverage was achieved by mounting four RSH-462 in each of the Shrine’s four minarets at a height of 33 metres from the ground. Four Lab.gruppen C28:4 four-channel power amplifiers are used to drive the Community loudspeakers, while system management is handled by an XTA DP446.
The loudspeakers are exposed to the elements, but with the one-piece, non-metallic diaphragm of the RSH-462 facing forward, the voice coil and magnetic structure of each driver are isolated from the environment.
Milad GhorbanNejad, commercial manager of Farasout Negar, commented: “We are very pleased with the sound levels, high intelligibility and coverage we have achieved with the RSH-462 loudspeakers and the combination of Community, Lab.gruppen and XTA has provided a system that ensures quality and long-term reliability.”
