Assembled to provide a robust base system for providing background music and audio entertainment for large and/or outdoor commercial spaces, this B&H Kit combines a Russound D890 8-Channel Digital Power Amplifier with a networked streaming audio player preamp, making it easy to distribute streamed audio to large audio installations.
The Russound D890 Amplifier is a robust 8-channel Class-D digital amplifier designed for larger spaces and outdoor areas, delivering the power and flexibility to elevate any audio system. Whether you're looking to enhance your home theater experience with rich, immersive sound or power multiple speakers throughout your home with your favorite music, the D890 is engineered to meet the challenge. With 90W per channel across four zones, this advanced digital amplifier ensures consistent, high-quality audio performance. Each zone has three input options—two shared bus inputs and a dedicated zone input—giving you versatile control over your audio sources. For even more power, zones can be bridged to deliver up to 180W, making the amplifier ideal for driving outdoor speakers or filling larger rooms with clear, dynamic sound.
One of the standout features of the D890 is its built-in audio filter for each zone. A simple slide switch on the rear panel allows you to select between full-range sound, a high-pass filter for smaller or architectural speakers, or a low-pass filter for subwoofer use. This enables you to tailor the amplifier’s output precisely to the speakers in each zone, optimizing sound quality throughout your system. Additional control features include three turn-on modes: Always On, Signal Sensing, and 12V Trigger Control, giving you flexibility in system integration. All of this is wrapped in a sleek new industrial design that looks great on a shelf or fits neatly into a standard 19" rack.
