Eight-Channel Digital Amplifier (D890) – Russound

D890 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. Being able to reduce the size of the amplifiers was a key goal of the new design, but Russound didn’t want to reduce any features and even wanted to add more than we’ve ever offered in the past. The new D-Series does just that by adding a new, easily configurable option to custom tailor the audio output for the desired application, from powering traditional speakers, to driving passive subwoofers added to any area of the home, indoors and out. These new amplifiers give installers the flexibility and reliability they need to satisfy the needs of their clientele, all while keeping an acceptable project budget. And they deliver the high-quality audio performance that their customers expect.
