INSTALLATION - PHYSICAL LOCATION AND MOUNTING
When you mount the PA635, you should plan its location carefully. Pay attention to each of the following factors:
Upper shelf, component, wall, etc.
2-inch spacing
(minimum)
PA635
To maximize air flow, route
single large opening in lower shelf.
Keep perforations on top cover free of
obstructions for max. cooling effect.
Keep perforations on bottom
plate free of obstructions.
Convection
Airflow

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 shelf-top installations.
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 = 1-3/4" (44.5mm) in height).
6. In multi-zone installations, you will have large bundles of wire and cable to accommodate audio, video and
speaker connections. Be sure to allow enough room for the leads and dress them in such a manner so as not
to block airflow.
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 seismically-active areas.
