The D-Series Power Amplifier is very easy to install and only requires three
connection types: audio source, power and loudspeakers.
Power is provided from the included 3-prong grounded electrical cord. The
amplifier accepts AC power from 115-230V, 50/60Hz.
RACK MOUNTING
When installed in a rack, the four mounting feet on the bottom of the chassis
may be removed if needed. Save the feet in case the amplifier is ever moved
back to a shelf-mounted type of installation so that they may be re-attached.
Do not use the amplifier on a shelf or other surface without the mounting
feet being installed. They help provide ventilation space at the bottom of
the amplifier. Leave at least 2” (5cm) of clearance around the amplifier for
ventilation.

The amplifier may be placed on a shelf or installed into an equipment rack
using the rack ears included within the box.
When connecting the loudspeaker wires, be sure to observe proper polarity.
The positive and negative terminals on the Russound D-Series amplifier must
correspond with the positive and negative terminals at both the left and right
loudspeakers. This is also true of the power connections at the loudspeaker
side of the connection.
Strip 1/8” (about 3mm) from each of the conductors for both the left and
right loudspeaker connections and insert them into the removable screwdown terminal, making sure to match the proper polarity of each connection.
Tighten the screw-down connections securely and make sure that there are
no exposed strands that might cause a short-circuit.

Please note that all wiring changes and changes to the settings switches on
the rear of the Russound D-Series amplifier should be done with the amplifier
powered o by removing the power cord from the rear of the amplifier.
The Russound D-Series amplifier includes a powerful feature called
“Bridging”. Bridging combines 2 adjacent output channels to form a single,
higher power mono output. It is perfect for larger spaces, and especially for
any outdoor audio zones where higher power is required.
COOLING FAN
The D-Series amplifiers use an internal cooling fan to minimize the internal
temperature when needed. The fan can operate at multiple speeds
depending on the environmental conditions and usage of the amplifier.
D890 and D1290 – When the unit is in Auto or 12V turn-on mode, the fan
should only be active when the amplifier is under heavy use or requires more
ventilation.
D1675 – When the unit is active, the fan will run at all times, at a low speed,
ramping up under heavy usage or if the unit requires more ventilation.

For the most eco-friendly operation, we recommend always using the
amplifiers on Auto mode which will allow the amplifiers to enter a low
Hardscape Subwoofer
power standby mode using less than ½-watt of power when not in use.
An easy-to-use slide switch is located on the
rear of your D-Series amplifier for each zone.
D890/1290D1675
LINE IN

B
LINE IN

The switch has 3 positions:
A – Setting the switch to this position will select Bus Input A as the audio
source for this zone
B – Setting the switch to this position will select Bus Input B as the audio
source for this zone
Line In – Setting the switch to this position will select the Zone Input as the
audio source for this zone.
Make sure that the switch is set properly for your audio system. Setting
this switch incorrectly will result in improper audio settings including lack
of audio in any zone where the improper source is selected.
INPUT CONNECTIONS
Connect your input source(s) according to your installation needs. To share
a source to multiple zone loudspeaker outputs, connect the source to one
of the Bus Inputs, either A or B. Make sure to set the Input Setting for each
loudspeaker output to the corresponding input, A or B. The Bus Input setting
allows your D-Series amplifier to work in many flexible configurations such
as sharing a single source in every zone, sharing up to 2 sources in any
combination of zones, or even using unique sources for every zone of the
amplifier.
The wiring method for bridged connections is dierent from that of normal
stereo pairs of loudspeakers. When bridging, only 8-ohm speakers may
be used. At the bottom of each speaker connector on the rear of your
Russound amplifier, you’ll see the alternate wiring configuration for a bridged
connection. One conductor of your loudspeaker wire will connect to the
left-most position on the speaker connector, and the second conductor
will connect to the right-most position as indicated. Please make sure to
verify the polarity of the wiring, matching the amplifier connection to the
loudspeaker connection.
Once the loudspeaker wiring has been configured, set the “Stereo/Bridged”
slide switch to the right for “Bridged” operation.
CONNECTING AUDIO SOURCES
There are two input types on your Russound D-Series amplifier:
Bus Inputs: Two analog stereo inputs: A and B
Zone Inputs: One analog stereo input for each zone
BUS INPUTS
The bus inputs can be shared by any zone of the amplifier. Use one of the bus
inputs if you want to share an audio source across more than one zone of the
amplifier. For example, if you have an audio streamer such as the Russound
MBX-PRE, connect its audio outputs to Bus Input A and you can then have
the audio streamer’s music played in any of the zones of the amplifier. With 2
Bus Inputs, your Russound amplifier can have 2 dierent audio sources that
are shared among configured zones of the system.
ZONE INPUTS
OUTPUT FILTER SETTINGS
The Zone Inputs are NOT shared to other zones of your Russound amplifier.
The Russound D-Series amplifiers have a
powerful feature allowing their output signal to be
attenuated specifically for the application of the
loudspeakers.
The switch applies advanced audio filters that
allow the output signal to be:

LP
HP

HP
LP
Use these inputs for a zone-specific input. For example, if creating a whole-
home audio system with an audio streamer for every room in the home,
connect each audio streamer such as the Russound MBX-PRE to each
Zone Input. By doing this, app or voice control of any audio system is easily
implemented.
Use quality RCA cables and make sure all cables are fully attached and
Full Range “Full” – The entire audio signal is sent unfiltered to the connected
loudspeakers, from 20Hz to 20,000Hz.
Low Pass “LP” – An advanced low-pass custom-designed filter is applied
to the audio path for the zone. Use this setting when connecting a passive
subwoofer to the zone. By combining this setting with a bridged zone, a
powerful subwoofer can be added to any zone or to multiple zones of the
amplifier. When configured for Low Pass, the frequency output is limited to
20Hz to 160Hz.
High Pass “HP” – An advanced high-pass custom-designed filter is applied
to the audio path for the zone. Use this setting to avoid sending excessive
low-frequency sounds to a loudspeaker that is not designed to handle them.
By customizing these audio filters, you can custom tailor the audio of the
installation to maximize the performance of the amplifier, the eiciency of
your loudspeakers, and maximize the audio components of the system to best
work together for their specific needs. When configured for High Pass, the
frequency output is limited to 80Hz to 20kHz.
POWER CONNECTION
Once the source and loudspeaker connections have been made and the input
setting, stereo/bridged mode setting, and output filter settings switches have
been set, you can connect the power cable to the rear of amplifier.
FRONT PANEL POWER BUTTON
The Front Panel Power Button will toggle between “On” and “Standby”
modes whenever the rear panel turn-on switch is set to Auto. If the rear
panel switch is set to “ON” or “12V”, the front panel switch will have no eect
because it is being overridden by the rear switch setting.
TRIGGER IN/OUT
The Trigger Input is used to turn on the D-Series amplifier, toggling between
standby mode when no 12V signal is present and On mode when a 12V signal
is present. This is very helpful for audio sources that have a low output signal
or where discrete, dedicated control of the amplifier status is required.
REAR PANEL SWITCH SETTINGS:
•ON- The Trigger Output will be active
•Auto – The Trigger Output will be active whenever any input signal is
detected
•12V – The Trigger Output will be active whenever there is a 12V input
signal detected
TURN ON MODE
Your D-Series amplifiers has three turn-on modes:
ON – The D-Series amplifier is always on and ready to be used. The amplifier
consumes more electricity in this mode.
12V – The D-Series amplifier will turn on whenever a 12V signal (~100mA) is
detected at the DC 12V trigger “In” connection. When no 12V signal is present,
the amplifier will enter standby mode after a brief delay and will consume less
than 0.5W of electricity.
AUTO – The D-Series amplifier will automatically detect an input signal for
each zone and will turn on when needed. When no signal is detected, the
amplifier will enter standby mode after a delay of approximately 10 minutes.
When in standby mode, it will consume less than 0.5W of electricity.
