SYSTEM PLANNING
CONTROLLER LOCATION
Consider all of the flowing when planning the Controller location:
1. The MRC88 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. Provide large holes in the shelf below the MRC88 and allow at least 2 inches
of space above the top cover to allow adequate airflow.
3. Never remove the chassis feet. They are required to create space for
adequate airflow.
4. Pay close attention to the overall thermal conditions within a cabinet if other
heat generating components are also being used.
5. Both MRC88 and MRAUDIO8X8 have built-in fans that will automatically turn
on at a manufacturer specified temperature. Use of external fans, (quiet, boxer
type) is recommended to provide constant airflow for the MRC88 and other
heat generating components when appropriate.
6. When rack mounting, always use a single ventilated rack space panel above
and below the MRC88.
7. The MRC88 is designed for horizontal mounting on flat surfaces. When rack
mounting, use a proper rack shelf or drawer. (Middle Atlantic or equivalent.)
8. In multi-zone installations there will be large bundles of wire and cable to
accommodate audio, video, speaker and control connections. Be sure to leave
enough room for the leads and dress them in such a manner as to not block
airflow.
