Figure 4 – HORIZONTAL MOUNTING
When mounting the PA4100X, you should plan its location carefully. Pay close attention to each of the following
factors:
1. The amplifier is convection cooled. That is, 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. 4). 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 and make sure top and bottom perforations are free
from obstruction..
3. If the cabinet contains other heat generating components, 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
PA4100X's and the other heat generating components.
5. When mounting in a 19" (483mm) rack, adding a double RU (Rack Unit) above and a single RU below the
PA4100X will improve convection in heavy use applications.
[One Rack Unit size = 1-3/4" (44.5mm) in height].
