The new D-Series multichannel amplifiers benefit from the latest high quality Class-D amplification providing efficient audio reproduction with low distortion levels, lower operating temperature, smaller size, and lower overall product weight. Designed to expand an audio system into more rooms or zones or to add increased audio output for larger rooms or outdoor areas where a higher output volume is required, Russound's D-Series multichannel amplifiers are only available through trained installation professionals.
"When engineering the D-Series, we wanted to deliver an amp that not only met our high standards in performance and quality, but also rethought the installation experience," says Charlie Porritt, CEO, Russound. "Each of the amp zones can be configured without any equipment — just set the switches on the back and it’s ready. This feature helps save installers an incredible amount of time in any multichannel amplification project. The D-Series demonstrates what amplification innovation looks like — it’s sleek, feature-rich, and powerful, giving installers the flexibility and reliability they need to satisfy the needs of their clientele, all while keeping an acceptable project budget."

Proof of the company’s commitment to adding more features, they also include new, easily configurable audio filter options to custom tailor the audio output for the desired application. Any stereo pair, zone, or bridged speaker connection on the D-Series models can be set to output three different options: Full Range Sound, which allows for a typical full range of sound between 20Hz and 20kHz to the connected loudspeaker(s). Low Pass Filter allows the connected speakers to only receive low frequency audio signals, from about 20Hz to 160Hz, perfect for supporting passive subwoofers with only the frequencies that the subwoofer can support. Finally, there is the High Pass Filter, which allows the zone or channel to focus on only the higher frequencies, from 80Hz and up. These filter options protect the amplifier by avoiding unneeded impedance swings from the speakers attempting to drive frequencies that the connected speakers are not capable of producing.
The D-Series amplifiers allow for up to three different input choices for every channel. Installers can use two available bus inputs as the input for any channel, or use a dedicated input, allowing for precise tailoring of any system to its needs. By combining multiple zones of audio amplification into a single chassis, any audio installation can easily grow and expand to other areas in and around the home, without the need for separate amplifiers and separate audio connections for every area. One amplifier can power multiple loudspeakers, organized around the home in the way that best fits the needs of the homeowner, or they can be bridged for applications that demand even more power.

The Russound D-Series D1290 and D1675 amplifiers will be available in March 2024, and the D890 is scheduled for release in Q3 2024.
