INTRODUCTION

Congratulations and thank you for your purchase of this precision Parasound audio component.

The Parasound Model 5250 v.2 is the latest generation of popular and proven audio power
amplifiers dating back to 1981. It has been designed for a wide variety of applications, establishing
a new standard for audio performance, user-friendliness and utility in custom installations.

The versatility of the Model 5250 v.2 allows many connection and configuration options, so
please be sure to read this manual thoroughly before you begin installation

Unpacking

Carefully unpack your Model 5250 v.2 and these accessories:

•

Detachable AC power cord

•

Trigger wire with a 3.5 mm mini plug at each end

Please inspect the unit now and contact your Parasound Dealer promptly if you see evidence

of shipping damage. Save the carton and packing inserts in case you move or in the event you
need to ship your amplifier for repair. Before you proceed, locate the serial number on the rear
panel or underside of the unit and record it here for future reference:

AC VOLTAGE, INSTALLATION AND RACK MOUNTING

115v – 230v AC Voltage

110–120V is the typical AC voltage in North America; most other countries supply 220–240V.
The 5250 v.2 is internally wired for either 115V or 230V, according to where you purchased it
and the voltage that is marked on its carton. If you plug a unit that is wired for 115V into a 230V
outlet it can damage it.

Note: Only a qualified repair technician should make AC voltage conversions.
For your own safety, please do not attempt this yourself!

Installation and Ventilation Requirements

Install your Model 5250 v.2 away from heat sources such as heating ducts, radiators, or other
heat producing components. Always position it horizontally.

Observe the following ventilation guidelines when installing the Model 5250 v.2 in an
equipment rack or any other enclosed space:

You should never install the Model 5250 v.2 in an unventilated equipment cabinet or compartment
because hot air will not exhaust adequately to prevent overheating. Air won’t often circulate
adequately in a cabinet or enclosure whose front and back sides are open; pockets of intense
heat can still develop around any heat-producing equipment. Therefore, a ventilation fan is highly
recommended. Allow a few inches of empty space on each side and above the unit and try to
avoid crowding or stacking the Model 5250 v.2 tightly between other components. A ventilation
fan is also recommended where other equipment must be mounted close to the Model 5250 v.2.

Do not place the unit on carpeting or any other material that could obstruct air flow into the
ventilation holes in its chassis bottom.

Rack Mounting

The Model 5250 v.2 occupies four rack spaces in a standard 19” equipment rack.

For rack mounting, you must use the Parasound RMK44 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 RMK44. This eliminates metal-to-metal contact between the Model
5250 v.2 chassis, the equipment rack, and the other components in the rack. Position these
washers on both sides so they “sandwich” the front panel before the mounting bolts are
screwed into the rack rail.
