Parasound A 51 - Manual (Page 4)

PLACEMENT GUIDELINES FOR YOUR A 51
Power amplifiers are usually heavier and generate more heat than other components. To avoid
damage to the A 51 or other equipment and to reduce risk of fire, you must follow these guidelines:
• A cable with a 2.5 mm sub-mini plug on each end (provided).
• Place the A 51 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 clear-
ance can be a little less.
• Do not block the front of the A 51 behind closed cabinet doors during use.
• Do not stack the A 51 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 51
To mount the A 51 into a 19" wide equipment rack, you must first attach its rack mount brackets
(provided). With its four feet removed, the A 51 chassis and front panel height occupies four
rack spaces (7" or 176 mm). When mounting equipment below the A 51, 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 devel-
oped by the EIA (Electronic Industries Association) so manufacturers of electronic components
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 51.
To attach the rack mount brackets:
• Remove the three screws from each side of the A 51. These are arranged vertically, behind its
front panel and in front of its first heatsink fin.
• Line up the three holes on each bracket with the three holes on the A 51 and reinsert the screws.
• Make sure the screws are tight because they will support the entire weight of the A 51 in the
equipment rack.
