SAFETY INSTRUCTIONS
6. Cleaning - The appliance should be cleaned only as
recommended by the manufacturer. From time to time you
should wipe o 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 nish or remove the panel lettering.
7. Ventilation - The appliance should be situated so 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. Place the
unit in a well-ventilated location, leaving at least 2 inches
(5 cm) of clearance on all sides, top and rear of unit for air
ow. If ventilation is blocked, the unit may overheat and
malfunction.
8. Heat - The appliance should be situated away from heat
sources such as radiators, heat registers, stoves, or other
appliances (including ampliers) that produce heat.
9. Grounding or Polarization - Precaution should be taken so
that the grounding or polarization means of an appliance is
not defeated.
10. 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.
11. 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.
12. Main Power Disconnect - The power switch is a single-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.
13. Non-Use Periods - The power cord of the appliance should
be unplugged from the outlet when left unused for a long
period of time.
14. Attachments - Only use attachments/accessories specied
by the manufacturer.
15. Carts and Stands - The appliance should
be used only with a cart or stand that is
recommended by the manufacturer. An
appliance and cart combination should be
moved with care. Quick stops, excessive
force and uneven surfaces may cause the appliance and cart
combination to overturn.
16. Wall or Ceiling Mounting - The appliance should be
mounted to a wall or ceiling only as recommended by the
manufacturer.
17. Location of the Amplier - Do not mount this unit 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.
18. Object and Liquid Entry - Care should be taken so that
objects do not fall and liquids are not spilled into the
enclosure through the openings.
19. Servicing - The user should not attempt to service the
appliance beyond that described in the operating
instructions. All other servicing should be referred to
qualied service personnel.
20. Damage Requiring Service - The appliance should be
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 is damaged.
CAUTION: TO REDUCE THE RISK OF ELECTRIC
SHOCK, DO NOT REMOVE THE COVER. NO USERSERVICEABLE PARTS INSIDE. REFER SERVICING
TO QUALIFIED SERVICE PERSONNEL.
WARNING: TO REDUCE THE RISK OF FIRE
OR ELECTRIC SHOCK, DO NOT EXPOSE THIS
APPLIANCE TO RAIN OR MOISTURE.
Note: This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to part 15 of the FCC rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment o and
on, the user is encouraged to try to correct the interference by one of
or more of the following measures: reorient or relocate the receiving
antenna; increase the separation between the equipment and
receiver; connect the equipment into an outlet on a circuit dierent
from that to which the receiver is connected, or consult the dealer or
an experienced radio/TV technician for help.
This Class B digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe B est conforme à la norme NMB003 du Canada.

Russound D850, D1650 Installation Manual
Introduction
The Russound D850 and D1650 multichannel digital ampliers are ideal for
use in adding additional power in distributed audio systems. The D850 provides
8 channels of digital amplication while the D1650 provides 16 channels. The
channels of both models are arranged in pairs to provide amplication for
stereo zones. Both models provide an array of useful features such as bridge
mode operation, global and independent zone triggering, audio sense circuitry
with adjustable delays per zone, a Bus Input and independent line inputs per
zone to meet a wide variety of applications and congurations.
Both models are rated at 50 watts per channel into 8 ohms and 80 watts
per channel into 4 ohms. With the stereo/Bridge Mono switch in the Bridge
position, channels are combined for a higher powered mono output of 160
watts into 8 ohms. The use of advanced digital amplication circuitry results
in a smaller, lighter chassis, with cooler operation than our previous amplier
models.
PRODUCT OVERVIEWTABLE OF CONTENTS
Thermal Protection
All Russound ampliers are designed with special circuitry to safeguard the
amplier under a thermal overload condition. Thermal protection mode can
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.
Protection Circuitry
All Russound ampliers are designed with special circuitry to safeguard the
amplier under a short-circuit condition. A faulty speaker can also cause a
short circuit condition. The Zone LED will blink rapidly between Red and Blue
when the Zone is in short circuit protection.
The amplier will auto-correct itself when the trouble condition has been
removed. The amplier will then resume normal operation.
Rack Mounting
Both ampliers 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.
