Data Sheet Russound’s R-Series amplifiers employ a robust circuit Two of the amplifiers have unique features for special design for stability under demanding loads. All models applications. The compact R235LS provides automatic feature auto signal-sensing inputs and bridgeable switching between a multiroom audio system and a local channel pairs for increased power output and flexibility of source, such as a TV or a computer. The R290DS takes application. All amplifier channels feature independent gain the dual source concept even further with line and speaker controls for precise level matching and dual speaker outputs audio inputs and auto sensing for both primary and for convenience. Optional rack-mount ears are included with secondary sources, a loop output, and more power. all models except the R235LS, which features a low-profile design and mounting capability integrated into the chassis. Features Total channels Bridgeable channel pairs Auto signal-sensing inputs Separate channel gain controls Thermal protection Short-circuit protection Rack mount ears included 12-volt trigger input & output Bus input & output Source loop outputs Automatic local source switching Power output per channel @ 4/8 Ohms Multi-power AC outlet
