Unpacking Your Model 2250 v.2 & Placement Guidelines

Carefully remove your Model 2250 v.2 from its shipping carton and locate the enclosed accessories:

• AC power cord

• Two 12V DC trigger wires with mono plugs, one with 3.5 mm (1/8‖) mini plugs, one with a 2.5mm

sub-mini plug and a 3.5mm mini plug

While you are unpacking your Model 2250 v.2, inspect it thoroughly for possible shipping damage and

tell your Parasound dealer immediately if you find any evidence of shipping damage. This would be a

good time to make a copy of your sales receipt to store with the Model 2250 v.2’s original packing.

Note: Please save and store both the inner and outer cartons and, most especially, the foam packing

inserts to protect the Model 2250 v.2 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.

The Model 2250 v.2 will be easier to use and will last longer if you follow these simple guidelines:

• Place the Model 2250 v.2 on a surface that will adequately support its substantial weight.

• Use input and output cables that are long enough to leave some slack; that will enable you to pull

the Model 2250 v.2 out of a cabinet to check or to change connections without inadvertently

disconnecting cables.

• The Model 2250 v.2 should never be placed in a completely enclosed cabinet

• Place your Model 2250 v.2 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.

• Always position the Model 2250 v.2 horizontally.

• The Model 2250 v.2 should never be stacked immediately on top of another power amplifier.

• Do not install the Model 2250 v.2 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.

The Model 2250 v.2 front panel occupies two rack spaces in a standard 19‖ equipment rack.

For rack mounting, you’ll need to use the Parasound RMK22 rack mounting kit (purchased separately).

We recommend that you use the 8 insulated shoulder washers with the four mounting bolts which are

included with the RMK22. Position these washers on both sides so they ―sandwich‖ the front panel

before the mounting bolts are screwed into the rack rail. This will eliminate metal-to-metal contact

between the Model 2250 v.2 chassis, the equipment rack, and the other components 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.

A single standard rack space is 1-3⁄4" (44mm) high in a 19" 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 Model 2250 v.2.
