product OVERVIEW Introduction Protection Circuitry The Russound R290DS is a 2-channel 90 watt dual source power amplifier with auto-source switching. It features Primary and Secondary audio line inputs with a loop out to another zone, receiver, or device from the Primary source. A signal only available as a speaker input can be connected and assigned as either the primary or secondary source. Special circuitry has been designed into the amplifier to safeguard under a short-circuit condition.

System Configuration - Stereo Mode The R290DS has dual source capability. If two sources are used, connect the source you want to have priority to the Primary input and the other source to the Secondary input. Whenever the Primary source is active, that signal will take priority over the distributed audio signal on the Secondary line.
