Unpacking Your Model 275 v.2 & Placement Guidelines
Unpacking Your Model 275 v.2
Carefully remove your Model 275 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 275 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 275 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 275 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.
Placement Guidelines
The Model 275 v.2 will be easier to use and will last longer if you follow these simple guidelines:
• Place the Model 275 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 275 v.2 out of a cabinet to check or to change connections without inadvertently
disconnecting cables.
• The Model 275 v.2 should never be placed in a completely enclosed cabinet
• Place your Model 275 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.
Ventilation Requirements
•
Always position the Model 275 v.2 horizontally.
•
The Model 275 v.2 should never be stacked immediately on top of another power amplifier.
• Do not install the Model 275 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.
Rack Mounting Your Parasound Model 275 v.2
The Model 275 v.2
front panel occupies only one rack space in a standard 19‖ equipment rack.
For rack mounting, you’ll need to use the Parasound RMK11 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 RMK11. Position these washers on both si
des 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 275 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 275 v.2.
