NO USER - SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE
PERSONNEL.
The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the products enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert
the user to the presence of important operating and maintenance
(servicing) instructions in the literature accompanying the appliance.
Double Insulated, when servicing use only identical replacement parts

not be situated on a bed, sofa, rug, or similar surface that may block the ventilation openings or, placed in a built - in installation, such as a bookcase or cabinet
that may impede the flow of air through the ventilation openings. Place the
DPA-4.8 in a well-ventilated location, leaving at least 2 inches (5cm) of clearance on all sides, top and rear of unit for air flow. If ventilation is blocked, the
DPA-4.8 may overheat and malfunction.
9. Heat - The appliance should be situated away from heat sources such as radiators, heat registers, stoves, or other appliances ( including amplifiers ) that produce heat.
10.Power Sources - The appliance should be connected to a power supply only of
the type described in the operating instructions or as marked on the appliance.
11 .Grounding or Polarization - The precautions that should be taken so that the
grounding or polarization means of an appliance is not defeated .
12. Power - Cord Protection - Power supply cords should be routed so that they are
not likely to be walked on or pinched by items placed upon or against them,
paying particular attention to cords at plugs, receptacles, and the point where
they exit from the appliance.
13. Cleaning - The appliance should be cleaned only as recommended by the manufacturer.
14. Non-use Periods - The power cord of the appliance should be unplugged from

E. The appliance has been dropped or the enclosure is damaged.
17. Servicing - The user should not attempt to service the appliance beyond that
described in the operating instructions. All other servicing should be referred to
qualified service personnel.
18. Avoid using a telephone (other than cordless type) during an electrical storm.
There may be a remote risk of electric shock from lightning.
19. Do not use the telephone to report a gas leak near the leak.
20. The apparatus shall not be exposed to dripping or splashing and that no objects
filled with liquids, such as vases, shall be placed on the apparatus.
PRECAUTIONS
1. Do Not Touch The DPA-4.8 With Wet Hands. Do not handle the DPA-4.8 or
power cord when your hands are wet or damp. If water or any other liquid
enters the DPA-4.8 cabinet, take the DPA-4.8 to qualified service personal for
inspection.
2. Location of the DPA-4.8 - Do not expose the DPA-4.8 to direct sun light or
heating units as the DPA-4.8 internal components temperature may rise and
shorten the life of the components. Avoid damp and dusty places.
3. Care – From time to time you should wipe off the front and side panels and the
cabinet with a soft cloth. Do not use rough material, thinners, alcohol or other
chemical solvents or cloths since this may damage the finish or remove the
panel lettering.

INTRODUCTION
Congratulations on your recent purchase of the Russound
DPA-4.8 8-channel amplifier. The DPA-4.8 high-current, highquality amplifier is the heart of the home theater or multizone system. The DPA-4.8 8-channel amplifier is capable of
amplifying four stereo line level sources (CD players, tape
decks, preamplifiers, tuners, etc.) simultaneously in multi-zone,
multi-source installations. The eight amplifiers are arranged in
pairs to provide four stereo amplifiers. With separate gain
controls for each channel, sound levels can be preset to
accommodate most rooms. The Main Bus Input allows for two
or more stereo amplifiers to share the same audio source.
With the stereo/mono selector in the mono position, two
amplifiers can serve as mono outputs. In the mono position
the four stereo pairs can be bridged to two stereo pairs for
higher output power. The DPA-4.8 power output is 50 watts
per channel into 8 ohms, and 75 watts into 4-ohms. Bridged
adjacent outputs provide 100 watts of power into 8-ohms
and 150 watts of power into 4-ohms. All this power is backed
by two high output toroidal transformers. Each amplifier output channel incorporates thermal, short circuit protection and
Russound’s unique Dynamic Clipping Sensor that allows for
better headroom and volume without clipping or distortion
that is normally heard in most amplifiers.
The Russound DPA-4.8 amplifier is built with pride. Fidelity,
reliability and quality are the primary objective. Russound
products are guaranteed to provide years of enjoyment.
