PRODUCT OVERVIEW Introduction Protection Circuitry The Russound R290DS is a 2-channel90 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.

SYSTEM CONFIGURATION - BRIDGED MODE Bridged Mode In this mode both the left and right channels are combined for a higher power mono output. For proper operation, the left channel adjustment should be set to the center position to start and then adjusted appropriately from there. The right channel adjustment is not applicable. 1. Unplug the R290DS. 2. Set the Stereo/Bridge switch to Bridge Mono. 3. Connect the line out from a preamplifier or source to the Left Primary input jack of the R290DS.
SYSTEM CONFIGURATION - EXTERNAL VOLUME CONTROL System Configuration with External Volume Control The R290DS can be configured for large autoformer-based volume control systems/speaker selectors.
