Source Flexibility
The D-Series amplifiers allow for up to 3 different input choices for every channel. Use either of 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.
Multi-Channel Power
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. Bridgeable for Even More Power Where Needed
Easy to Configure Audio Filter Options
The D-Series offers a new audio filter configuration option, normally not available in amplifiers of this price point, allowing for easy to adjust modifications to the output frequency range. Any stereo pair, zone, or even bridged speaker connection on
these models can be set to output any of 3 different options:
Full Range Sound – This is the default setting and allows for a typical full range of sound between 20Hz and 20kHz to the connected loudspeaker(s).
Low Pass Filter – This setting allows the connected speakers to only receive low frequency audio signals, from about 20Hz to 160Hz, perfect to support passive subwoofers to add some extra bass to any area of the home. By filtering the output, the D-Series amplifier can more efficiently support only the frequencies that the subwoofer can support, allowing for much more efficient, more robust, and more dynamic sound.
High Pass Filter – As with the low pass filter option, this setting allows the zone or channel to focus on only the higher frequencies, from 80Hz and up, providing the same efficient, robust, and dynamic sound to traditional loudspeakers, and not wasting energy on lower frequency sounds that the speaker can’t even provide.
Control Flexibility
The D-Series amplifiers offer three turn-on modes, allowing for easy configuration of any audio system.
Always On – On this setting, the amplifier is ready 24/7 to provide amazing sound throughout the home.
Signal Sensing – On this setting, the amplifier can reduce its energy consumption when not being used to less than 0.5 watts of power, but is ready to turn-on quickly to be ready to rock the party, play a podcast, watch a movie or TV show, or just to allow anyone’s favorite music to be enjoyed.
12V Trigger – This setting allows an installer to custom configure exactly when the amplifier turns on and off, giving it the best of both worlds, proper turn on so that the amplifier is ready exactly when needed while maximizing the potential electricity savings of standby mode. The 12V trigger output allows this same turn-on signal to be cascaded to other devices in the home, including other D-Series amplifiers when used in a very large system.
Overview:
Russound’s D-Series of amplifiers are synonymous with premium performance, reliability, and durability, forming the backbone of professional audio installations around the world. The newest generation builds upon the legacy of these prestigious products and is offered in three compelling models: D890 - 8 Channels (4 Zones) of Audio, D1290 - 12 Channels (6 Zones) of Audio, and D1675 - 16 Channels (8 Zones) of Audio.
Each of these models is designed to expand an audio system into more rooms or areas or to add increased audio output for larger rooms or outdoor areas where a higher output volume is required.
While these amplifiers pack a punch with up to 90 watts per channel on the D890 and D1290 models and a massive 75 watts per channel in up to 16 channels in the D1675, these models utilize an advanced digital design which results in smaller chassis sizes than in any previous generation of Russound amplifiers. The 8 and 12 channel models are only a single rack-unit in height and the 16 channel takes up only 2 rack-units.
