Introduction

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.

Thisamplifier canbeusedforpowerupgradesinspecific zones,forlargespeaker selector or volume control systems and for long series-parallel speaker runs (e.g., large outdoor zones).

The R290DS is rated at 90 watts per channel into 8 ohms, and 110 watts into 4 ohms. With the Stereo/Bridge Mono switch in the Bridge Mono position, both amplifier channels are combined for a higher powered mono output. In Bridge mode the R290DS is rated at 220 watts of power into a single 8 ohm load. Each amplifier output channel incorporates robust protection circuitry for safety and reliability under extreme circumstances.

The 12V Trigger In/Out allows the R290DS to be activated by other electronics or to activate other electronics via a 3.5 mm mini phone plug cable.

Protection Circuitry

Special circuitry has been designed into the amplifier to safeguard under a short-circuit condition. A faulty speaker can also cause a short circuit condition.

The front panel LED illuminates orange when the amplifier is in short circuit protection. If this fault condition occurs, turn off the amplifier and check speakers for short circuit conditions when appropriate.

Rack Mounting

The R290DS amplifier can be rack mounted using the included rack-mount ears and hardware to attach the ears to the amplifier. The amplifier will take two rack spaces with the feet removed.

If mounted in a rack , one open rack space above and below is recommended to allow for ventilation and heat dissipation.

Thermal Protection

All Russound amplifiers are designed with special circuitry to safeguard the amplifier under a thermal overload condition. Thermal protection mode will only engage when the unit has been run at high volume for extended periods of time without adequate ventilation and/or when speaker impedances are below the minimum levels for the amplifier. In thermal protection mode the amplifier will automatically stop output and the status indicator LED will go OFF. If this fault occurs, turn off the amplifier, and check that the speaker impedance rating is above the minimum rating. Also check for adequate ventilation around the amplifier and make adjustments if necessary. Once the unit has cooled to safe operating temperatures, the amplifier may be powered back on.
