[. . . ] Application Note IC-1 Revision 1. 0 February, 2008 Flush mounting the Iconyx Series Abstract: Flush mounting any loudspeaker requires special design consideration and self-powered loudspeakers require extra planning for adequate cooling. This application note discusses those design considerations and makes recommendations for flush mounting the Iconyx series of steerable line arrays. Even though the Iconyx series of steerable column arrays are very low-profile and can be installed in many applications where conventional loudspeakers would be visually unacceptable, there are still some venues where even the very slender Iconyx arrays need to be hidden. [. . . ] Amplifier Cooling The Iconyx series are self-powered loudspeakers so cooling for the internal amplifiers must be addressed. The amplifiers used in the Iconyx are all Class D, Class D amplifiers run very efficiently and thus relatively cool, but you must provide for some cooling airflow. The hinge kit mounting brackets will space the loudspeaker far enough off the mounting surface to allow airflow, you must allow enough space around the loudspeaker for the cooling air to circulate. In addition you must allow the hot air to exit the recess and cool air to enter. It is best to do this by extending the opening for the loudspeaker several inches or centimeters above and below the array. Please see the drawing for minimum recommended sizes of these openings. 1 These guidelines assume the loudspeaker and its recess are exposed to temperatures not exceeding normal indoor temperatures. Indoor installations should avoid sources of heat such as heating ducts and radiators, lighting fixtures, etc. If the loudspeaker is installed outdoors, you need to allow more airflow around the loudspeaker, substantially more if the installation will be exposed to full sunlight. The cooling provided by the ventilation suggested should be sufficient for any normal operation of the loudspeakers. If, however, the loudspeakers are continuously run very close to or even into their protection limiting, the power amplifiers may eventually "thermal off. " If this happens, you'll need to install fans or some other method of positive cooling, or reduce the level of the loudspeakers. Grill Material For the grill material, Renkus-Heinz recommends acoustically transparent fabric specifically designed for loudspeaker use. This is available from companies such as Acoustone and Mellotone. The fabric used to cover fiberglass acoustic panels is often not particularly transparent at high frequencies and is not recommended.
