Russound D250LS 2-Channel Local Source Priority Power Amplifier
The Russound D250LS 2-Channel Digital Power Amplifier is specifically designed for distributed audio applications requiring automatic local source switching. Delivering 50 Watts per channel into 8 Ohms (75 Watts into 4 Ohms) or 150 Watts bridged mono, the D250LS allows homeowners to enjoy whole-house background audio while seamlessly switching to a local source—such as a bedroom TV, gaming console, or dedicated media streamer—the instant audio playback begins.
Equipped with an optical digital input alongside primary and secondary analog RCA inputs, the D250LS provides crystal-clear digital sound directly from modern displays without requiring digital converters. Adjustable sensitivity threshold and return-delay controls ensure smooth, glitch-free audio transitions, returning back to the whole-house system automatically when local playback stops.
