16-channel multi-room power amplifier
Our take on the Russound D1650 by Crutchfield's Dave Bar
Powerful, cool-running multichannel power amp
Russound's D1650 amplifier offers versatile multi-room flexibility and plenty of power when and where you need it for top-notch sound. Enjoy clear stereo sound in eight rooms, or combine two channels into one to give your speakers more juice — a great option for power-hungry outdoor speakers. And unlike traditional amps that run hot and waste a lot of energy, the D1650 boasts a high-efficiency Class D amplifier design for cool operation, reduced weight, and clean, undistorted sound even at high listening volumes.
More flexible options for enjoying music throughout your home
The D1650 can distribute music from one audio source, such as a networked music streamer, to multiple rooms in your home. Or you can connect up to eight separate sources and play a different one in each listening room. Each of the amplifier's playback "zones" features independent left- and right-channel gain controls so you can adjust its output to fine-tune the levels of each speaker in your system. For music playback in more than eight rooms, you can daisy-chain multiple Russound amplifiers together.

Russound D1650 Reviews
Average Customer Review(s):
Thanks for submitting your review
16-Channel/8-Zone Amplifier: The Russound D1650 digital multichannel amplifier offers the features custom installation professionals demand while offering a lighter weight, smaller chassis and more efficient Class D power. The feature-rich design of the D1650 is ideal for the demands of distributed audio systems and is also compatible with our Russound volume controls. The D1650's sixteen channels are arranged in stereo pairs to provide discreet amplification and custom configurations for each of eight zones.
System Configuration: The Russound D1650 can be configured as the main amplifier for an audio distribution system or home theater system.
- Distributed Audio: When used with an audio distribution preamp, each zone can independently drive one of several different sources by using each zone's individual line audio inputs, or a pair of zones can be bridged to create a higher powered zone.
- Home Theater Application: The D-Series amp is even up to the rigorous demands of home theater applications, easily transforming into a powerful 160 watt x 8 channel amplifier (in bridged mode). You can also choose to individually un-bridge pairs for lower power applications such as Dolby Atmos or surround speakers. As an example, you could run a Dolby Atmos 7.1.2 system at 7 channels @ 160W and 2 channels @ 50W. Or, the remaining zone can be used for powering an additional area such as an outdoor zone.
Bridged Mode: When the amplifier is in Bridged mode operation, both the left and right channels are combined for a higher power mono output. In bridged mono mode, both channels in any zone become a robust mono output delivering 160 watts of power into an 8Ω load.
Ultra-Low Distortion: Ultra-low distortion output (relatively unheard of in other multi-zone amplifiers) allows for clean, undistorted audio even at high listening volumes.
Auto Sensing Zone Inputs w/ Independent Control: Each zone of the amplifier features a stereo RCA input. These line-level inputs are auto-sensing and will activate when an audio signal from a source is present. Each Zone input offers independent gain control for the left and right RCA channel. When used in Bridged Mode, only the left gain is used.
Bus Input & Output: The bus line input is a stereo RCA input that can be used to connect a single source to multiple zones. The bus line output is a stereo RCA output that allows passive passthrough of the Bus Input and can be used to daisy chain the source to other amplifiers in the system.
Speaker Outputs: The Russound D1650 multichannel amplifier is fitted with phoenix-style speaker connectors. The minimum speaker impedance is 4Ω for Stereo Mode and 8Ω for Bridge Mode.
Trigger Inputs/Outputs: The Russound multiroom amplifier features Zone 12V trigger inputs/outputs (3.5mm) and Bus 12V trigger inputs/outputs (3.5mm) for added convenience.
- Zone 12V Triggers: The Zone 12V Trigger In is used to activate a specific zone. The Zone Trigger Out can be used to trigger other 12V devices. The delay and audio sensing are bypassed when the 12V Zone Trigger Input is used.
- Bus 12V Triggers: The Bus 12VDC Trigger In is used to activate all zones that are using the Bus Input and disables other zone triggers or signal sensing on those zones when it is used. If the Bus Trigger In has 12V applied to it, only the 12V Bus Trigger Out will have 12V and the Zone Trigger Outputs will not.
Zero Hum: Advanced triggering options allow the amps to operate on demand. Apart from the obvious energy efficiency, there is no amplifier hum on your speakers when the system isn't in use.
Zone Indicator LEDs: The eight LEDs on the unit's front-panel correspond to the D1650's eight stereo zone amplifiers. The LEDs will illuminate blue when the amplifier power is on and a zone is active. The LEDs do not illuminate when a zone is off.
Protection Circuitry: A robust protection circuit provides efficient, safe and reliable operation under extreme conditions and protects each amplifier output channel. Russound's resilient protection circuit maintains safe and dependable operation in maximum performance conditions.
- Thermal Protection: The amplifier is designed with special circuitry to safeguard the amplifier 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 amplifier.
- Short Circuit Protection: The Russound amplifier is also designed with special circuitry to safeguard the amplifier 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.
Note: The amplifier will auto-correct itself when the trouble condition has been removed. The amplifier will then resume normal operation.
Auto Standby: The amplifier will go into Standby mode when audio signal or trigger is not present, and after the minimum delay time has timed out. The amplifier consumes 0.5 Watt or less current while in standby power mode. Standby delay can be adjusted to either 5 seconds, 5 minutes, or 10 minutes by using the DIP switches on the rear panel. This delay is selectable per zone. When an audio signal is not present, the amplifier will automatically go into standby mode after the preset period of time.
Rack Mountable: The multichannel power amplifier includes a
set of rack ears for rack mounting applications. The amplifier will take two rack
spaces with the feet removed.
Optional Volume Controls: The D1650 amplifier has been tested to work with all Russound autoformer-based volume controls (sold separately).

Reviews on other sites, as well as the information contained at Crutchfield. I chose the Russound amp over the Dayton Audio MA1260 [ David Aug 24, 2017 ]
I have not installed this equipment as yet. Mama has given very strict warning to finish the list of projects on my plate. Yeah, it kinda reminds me of days gone by, "Rich, have you eaten all your veggies?" Yes Mom! The dog didn't eat them either. They were still on the ground, where I'd tossed them out the window! However, the D1650 will be a great addition to the whole house audio when it replaces the manual knob controlled speaker selector switch. Will do an update once installed. [ Richard Jun 07, 2017 ]

7 questions already asked
3 answers I use the Russound D1650 to power zone 2 from my Onkyo TX-8160. On 7 of the 8 zones I am powering Polk MC80 in ceiling speakers with the Russound ALT-126R volume control. The system operates and sounds GREAT. i plan to use Zone 8 for my attached 20' by 40' 3-car garage with 9 ' ceiling. Would Bose 301 wall mounted speakers work with my system, or should I continue to use the Polk MC80 in ceiling speakers? Just looking for the best sound. [ Daniel Aug 07, 2017 ]
I use in ceiling speakers w my onkyo receiver . Sounds great [ KYLE Aug 08, 2017 ]
I do not know about those other items. I use the 301's by themselves. A stereo sound purist and like to hear exactly how they put the final mix together in the studio which appears on the recordings. 301s sound superb in all my estimations for what I need. [ robert Aug 08, 2017 ]
I have a pair of 301s they have great sound and can Handel a lot of power , you can always move them to different rooms , or take them when you move , you can't go wrong with the Bose . I have 201s 401s and 601s so I am a big Bose fan [ Bruce Aug 07, 2017 ]
Requires a pre amplifier, if that does Chromecast the amplifier will work. Any regular gauge specked wire will work # 18 is what I used [ William Jul 29, 2017 ]
Thanks for your question. For information on comparing two or more models I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget. [ Kenny Mar 14, 2017 ] Staff

No [ William Mar 08, 2016 ]
Jesse, this amp does not have an internet connection (WI-FY or Ethernet). The only controls on the unit are power and gain (screwdriver adjustment on the rear panel for gain). The unit can be turned on / off with a hardwired 12 volt signal or it can sense the presence of audio for auto on/off. No other control options exist. John [ JOHN Mar 07, 2016 ]
No, my Yamaha receiver Zone 2 runs through the Russound amp which turns on and off depending on the signal output of the reciever. I use the Yamaha app to control the system. [ David Mar 07, 2016 ]
You can power up to two speakers per channel and that would give you two pairs per zone. I recommend calling an advisor on 1-800-324-9695 to discuss your setup and see if this will work for your setup and performance goals. [ Paul Jan 04, 2016 ] Staff
Russound does not have a published specification for all channels driven; just the 2 channel specs at 1kHz & 8 Ohms: 50 watts RMS. (80 watts RMS at 4 Ohms). While I know this isn't the answer you were looking for, I hope the information helps. [ Ryan Dec 02, 2015 ] Staff
