Location of the Amplier - Do not mount this unit 7.
under a kitchen cabinet. Do not expose the amplier
to direct sun light or heating units as the amplier
internal components’ temperature may rise and
shorten the life of the components. Avoid damp and
dusty places.
Ventilation - The appliance should be situated so 8.
that its location or position does not interfere with
its proper ventilation. For example, the appliance
should 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 ow of air through the
ventilation openings.
Heat - The appliance should be situated away from 9.
heat sources such as radiators, heat registers, stoves,
or other appliances (including ampliers) that
produce heat.
Power Sources - The appliance should be connected 10.
to a power supply only of the type described in
the operating instructions or as marked on the
appliance.
Grounding or Polarization - Precaution should be 11.
taken so that the grounding or polarization means of
an appliance is not defeated.
Power Cord Protection - Power supply cords should 12.
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.
Main Power Disconnect - The power switch is a single-13.
pole switch. When the switch is in the “O” position,
the appliance is not completely disconnected from
the main power. The main power plug is used as the
disconnect device and shall remain readily operable.
When installing the product, ensure that the plug is
easily accessible.
Cleaning - The appliance should be cleaned only as 14.
recommended by the manufacturer.
Non-Use Periods - The power cord of the appliance 15.
should be unplugged from the outlet when left
unused for a long period of time. To remove all power
(supply mains) from the appliance, remove the plug
from the wall outlet.
Object and Liquid Entry - Care should be taken so that 16.
objects do not fall and liquids are not spilled into the
enclosure through the openings.
Servicing - The user should not attempt to service the 17.
appliance beyond that described in the operating
instructions. All other servicing should be referred to
qualied service personnel.
Damage Requiring Service - The appliance should be 18.
serviced by qualied service personnel when:
A. The power supply cord or the plug has been
damaged.
B. Objects have fallen, liquid has been spilled into the
appliance;
C. The appliance has been exposed to rain; or
D. The appliance does not appear to operate
normally; or
E. The appliance has been dropped or the enclosure

Introduction
The Russound R290DS is a 2-channel 90 watt dual source power amplier with
auto-source switching. It features Primary and Secondary audio line inputs with
a loop out to another zone, receiver, or device from the Primary source. A signal
only available as a speaker input can be connected and assigned as either the
primary or secondary source.
This amplier can be used for power upgrades in specic zones, for large speaker
selector or volume control systems and for long series-parallel speaker runs
(e.g., large outdoor zones).
The R290DS is rated at 90 watts per channel into 8 ohms, and 110 watts into 4
ohms. With the Stereo/Bridge Mono switch in the Bridge Mono position, both
amplier channels are combined for a higher powered mono output. In Bridge
mode the R290DS is rated at 220 watts of power into a single 8 ohm load. Each
amplier output channel incorporates robust protection circuitry for safety and
reliability under extreme circumstances.
The 12V Trigger In/Out allows the R290DS to be activated by other electronics
or to activate other electronics via a 3.5 mm mini phone plug cable.
Thermal Protection
All Russound ampliers are designed with special circuitry to safeguard the
amplier under a thermal overload condition. Thermal protection mode will
only engage when the unit has been run at high volume for extended periods
of time without adequate ventilation and/or when speaker impedances are
below the minimum levels for the amplier. In thermal protection mode the
amplier will automatically stop output and the status indicator LED will go OFF.
If this fault occurs, turn o the amplier, and check that the speaker impedance
rating is above the minimum rating. Also check for adequate ventilation around
the amplier and make adjustments if necessary. Once the unit has cooled to
safe operating temperatures, the amplier may be powered back on.
Protection Circuitry
Special circuitry has been designed into the amplier to safeguard under
a short-circuit condition. A faulty speaker can also cause a short circuit
condition.
The front panel LED illuminates orange when the amplier is in short circuit
protection. If this fault condition occurs, turn o the amplier and check
speakers for short circuit conditions when appropriate.
Rack Mounting
The R290DS amplier can be rack mounted using the included rack-mount
ears and hardware to attach the ears to the amplier. The amplier will take two
rack spaces with the feet removed.
If mounted in a rack , one open rack space above and below is recommended
to allow for ventilation and heat dissipation.
