Russound just dropped the D-Series Multichannel Digital Amplifiers; the eight-channel D890, the 12-channel D1290, and the 16-channel D1675. Designed to expand an audio system into more rooms or zones, or to add increased audio output for larger rooms or outdoor areas where a higher output volume is required, Russound says the amps are distinguished by their source and control flexibility, multichannel power and easy-to-configure audio filter options. The D1290 is the first in the series available and are already shipping.
