The Russound D890 is the eight-channel member of Russound's D-Series Class D amplifiers, designed for whole-home and light-commercial racks that need a lot of clean power in little space. Its 8 channels are organised as 4 independent stereo zones rated at 90 watts per channel into 4 ohms (one zone driven) and 45 watts into 8 ohms, and any zone can be bridged for 180 watts into an 8-ohm load when a patio, gym or great room needs more headroom. Two shared bus inputs let one or two sources feed many zones without Y-cables, while each zone can instead take its own dedicated input. A per-zone rear switch sets full-range, low-pass or high-pass operation, so a pair of channels can drive a passive subwoofer while others run small in-ceiling or landscape speakers more efficiently. The amplifier can stay on, wake on signal, or follow a global 12V trigger, and fan cooling keeps it stable in a packed 1U rack position.
