PLACEMENT GUIDELINES FOR YOUR JC 1

1

Power  amplifiers  are  usually  heavier  and  generate  more  heat  than  other  components.  To  avoid 

damage to the JC 1 or other equipment and to reduce risk of fire, you must follow these guidelines:

• 

Place the JC 1 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 JC 1 behind closed cabinet doors during use.

• 

Do not stack the JC 1 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 JC 1

To mount the JC 1 into a 19” wide equipment rack, you must first attach its Rack Mount Adapters 

(provided). With its four feet removed, the JC 1 chassis and front panel height occupies four rack 

spaces (7” or 176 mm). When mounting equipment below the JC 1, you will also need to allow 

about 1/8” below the unit for the bottom chassis screws. 

To attach the rack mount adaptors

• 

Remove the three shiny screws from each side of the JC 1.  These are arranged vertically, 

behind its front panel and in front of its first heatsink fin. 

• 

The angled part of the brackets that attaches to the rack should be just behind the front 

panel. 

• 

Line up the holes on each rack mount adaptor with the holes on the unit and reinsert the 

three screws. 

• 

Make sure the screws holding the rack mounts are tight because they will support the entire 

weight of the JC 1 when it’s installed into the equipment rack.

A  single  standard  rack  space  allows  1-3/4”  vertical  inches  in  a  19-inch  wide  equipment  rack. 

This  measurement  standard  was  developed  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 JC 1.
