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:

ƒPlace the JC 3 on a shelf that will adequately support its weight.

ƒUse 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.

ƒIf 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.

ƒPlace your JC 3 where you can route input and output signal cables as far as possible from any AC cords.

ƒWhere 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.
