Russound d890 8-channel Multi-room Power Amplifier

Product Description

The RUSSOUND d890 is an 8-channel multi-room power amplifier designed for distributed audio installations across residential and light commercial environments. It delivers 45 watts per channel and supports bridged operation, allowing paired channels to combine for up to 180 watts of output when driving a single zone at higher power. The d890 includes selectable high-pass, low-pass, and full-range filter settings on each channel, giving installers precise control over speaker frequency response without external crossovers. Licensed audio-visual or low-voltage contractors are the typical installers for this class of equipment.

The d890 supports four independent playback zones, making it well suited for whole-home audio systems where separate rooms or areas require individual source and volume control. Typical applications include background music distribution in homes, offices, retail spaces, and hospitality environments. Each zone operates independently, so audio in one room can be adjusted or muted without affecting the others. The amplifier is sized for rack-mount or equipment-closet installation, keeping the signal path centralized while speakers are distributed throughout the structure.

Installation Notes

Installation should be performed by a licensed low-voltage or audio-visual contractor familiar with distributed audio wiring practices. Power down the amplifier and disconnect all source and speaker connections before servicing or reconfiguring channel assignments. Follow local building codes and NEC guidelines for in-wall speaker wiring and equipment-room installations. Do not bridge channels beyond the rated configuration or connect loads below the minimum impedance specified in the manufacturer documentation.
