1.The amplifier is convection cooled - it depends on the natural free flow of air up through the slot perforations in the bottom plate, over the internal heat dissipating fins, then out the top cover, for adequate cooling.
2.If mounted in an equipment cabinet or other confining location, allow at least 2 inches of space above the top cover (see Fig. 5). Be sure there are large openings in the shelf below the unit and in the cabinet to allow the entry of cool air and the escape of warm air.
NOTE: Do not remove feet in
3.If the cabinet contains other heat generating components or you are using several PA635's in a large multi- zone system, you will have to pay even closer attention to adequate ventilation.
4.Do not hesitate to use fans (quiet, boxer type), if necessary, to ensure a constant flow of air through the PA635's and the other heat generating components.
5.When mounting in a 19" (483mm) rack, adding a single RU (Rack Unit) above and below the PA635 will improve convection in heavy use applications (one Rack Unit size =
6.In
7.The PA635 is designed for mounting into standard 19" Rack Panels or on flat horizontal surfaces. When mounting into a 19" rack, use the rack panel cup washers and screws supplied.
NOTE: You should consider some sort of rear support for rack mounted units when used in mobile applications or when located in
