INSTALLATION - PHYSICAL LOCATION AND MOUNTING

Figure 5 – HORIZONTAL MOUNTING

When you mount the PA435X, 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.

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 PA435X'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 PA435X 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 strain relief for the leads and dress them in such a manner so as not to block airflow.

7.The PA435X is designed for shelf mounting on flat horizontal surfaces. When mounting into a 19" rack, use an appropriate rack kit.
