User manual RUSSOUND R-SERIES DATASHEET

[. . . ] Data Sheet R-SERIES AMPLIFIERS R235LS, R290DS, R850MC, R1250MC Russound's R-Series amplifiers employ a robust circuit design for stability under demanding loads. [. . . ] The compact R235LS provides automatic switching between a multiroom audio system and a local source, such as a TV or a computer. The R290DS takes the dual source concept even further with line and speaker audio inputs and auto sensing for both primary and secondary sources, a loop output, and more power.
