Unpacking Your JC 3 & Placement Guidelines
Unpacking Your JC 3
Carefully remove your JC 3 from its shipping carton and locate all the enclosed accessories:
• AC power cord
• Two trigger wires, one with 3.5 mm mini plugs, one with a 2.5mm and a 3.5mm mini plug
While you are unpacking your JC 3, inspect it thoroughly for possible shipping damage and tell
your Parasound dealer immediately if you find any. If possible, save and store both the inner and
outer cartons and–most especially–the foam packing inserts, to protect the JC 3 if you have to
move it or ship it. You may wish to flatten the cardboard cartons to save room in storage after
cutting the taped seams on the bottom flaps. This would be a good time to make a copy of your
sales receipt to store with the JC 3’s original packing.
Placement Guidelines
The JC 3 will be easier to use and will last longer if you follow these simple guidelines:
Place the JC 3 on a shelf that will adequately support its weight.
Use input and output cables that are long enough to leave some slack; that will enable
you to pull the JC 3 out of a cabinet to check or to change connections without
inadvertently disconnecting cables.
If you’re putting the JC 3 in a cabinet, it needs a space that’s at least 22 inches wide so
you’ll be able to turn it around for access to its rear panel connections.
Place your JC 3 where you can route input and output signal cables as far as possible
from any AC cords.
Where signal cables must cross AC cords they should do so only at a 90° right angle.
Ventilation Requirements
• Always position the JC 3 horizontally.
• We recommend that you do not place the JC 3 above a power amplifier.
• Do not install the JC 3 in an unventilated equipment cabinet or compartment. Pockets of
stagnant hot air can build up even in a cabinet with an open front and back. A ventilation
fan such as the Parasound Zbreeze is highly recommended to prevent “hot spots” in
confined spaces.
Rack Mounting Your Parasound JC 3
With its four feet removed, the JC 3’s front panel height occupies two rack spaces: 3.5" or 88.2
mm. (A single standard rack space occupies 1.75" vertical space.) For mounting in a standard
19” equipment rack, you must use the Parasound HRA 2 rack mount kit (purchased separately).
The HRA 2 kit includes four bolts and eight plastic washers with raised “shoulders.”
Slide one washer onto each mounting bolt with its raised shoulder pointing toward the panel hole.
Carefully insert the bolt through the hole and slide the other washer on the bolt with its raised
shoulder facing the rear side of the panel. The washers will sandwich the JC 3 panel and the
four mounting bolts to prevent metal-to-metal contact between the JC 3 chassis, the equipment
rack, and the other components mounted in the rack.
Note: Tighten each bolt just enough to keep the unit secure in the rack to avoid deforming the
shoulder washers. Eliminating metal-to-metal contact reduces the likelihood of creating a ground
loop that might introduce hum into your system.
