PLACEMENT GUIDELINES FOR YOUR A 52
Power amplifiers are usually heavier and generate more heat than other components. To avoid
damage to the A 52 or other equipment and to reduce risk of fire, you must follow these guidelines:
•
Place the A 52 on a separate shelf that will adequately support its weight.
•
Keep it away from heat sources such as air ducts or radiators.
•
Avoid placing it on carpeting or another material that might obstruct airflow into the
openings in the chassis bottom.
•
Leave at least 3" of space around both sides and 6" of space above the top. The bottom
clearance can be a little less.
•
Do not block the front of the A 52 behind closed cabinet doors during use.
•
Do not stack the A 52 with other components inside a cabinet unless you use a fan
to circulate and exhaust the warm air that builds up between them.
Rack Mounting Your Parasound A 52
To mount the A 52 into a 19" wide equipment rack, you must first attach its HRA 3 rack mount
brackets (not included). With its four feet removed, the A 52 chassis and front panel height occu-
pies three rack spaces (5
1
⁄
4
" or 133 mm). When mounting equipment below the A 52, you will
also need to allow about
1
⁄
8
" below the unit for the bottom chassis screws. A single standard rack
space allows 1
3
⁄
4
" vertical height in a 19" wide equipment rack. This measurement standard was
developed by the EIA (Electronic Industries Association) so manufacturers of electronic compo-
nents and equipment racks could build products in standardized heights that would fit in a uniform
space. Please call your Parasound dealer or Parasound Technical Services if you need additional
advice about rack mounting the A 52.
To attach the rack mount brackets:
•
Remove the two screws from each side of the A 52’s top cover.
•
Line up the two holes on each HRA 3 bracket with these holes on the A 52 and attach
the brackets with the longer screws that are in the bracket kit.
•
Make sure the screws are tight because they will support the entire weight of the A 52
in the equipment rack.
