Russound R290DS System Configuration Stereo Mode, Dual source connections, Speaker Level Signal

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. The signal is still active on the Secondary line, and once the Primary audio signal is muted or turned off the R290DS will automatically switch back to the Secondary audio signal.

Stereo Mode

The R290DS can be configured as a power upgrade for specific zones, for use with large speaker selectors, and for long parallel speaker runs (outdoor zones)

1.Unplug the R290DS.

2.Set the Stereo/Bridge switch to Stereo.

3.Connect the audio line output from a stereo preamplifier or source to the left and right Primary input jacks of the R290DS. If the output is only available as speaker level see Speaker Level Signal at right.

4.Connect the audio line output from the secondary source to the Secondary input jacks in the same manner.

5.Connect your speakers to the terminals, observing proper polarity.

6.Restore power to the amplifier. Both channel levels can be adjusted with the corresponding channel level adjustments.

Dual source connections

Connect the source audio outputs to both Primary and Secondary inputs as instructed above.

Set the delay with the DelayTime knob.The DelayTime adjustment determines when the switch back to the Secondary signal will occur. Example: If the primary source is a CD changer, increasing the delay time will prevent a switch back to the secondary source while the disc is changing.

Note: This works with all incoming signals, line level or speaker level.

Speaker Level Signal

If either of the sources is only available as a speaker level signal, connect it to the Speaker In terminals, using the screw down terminal block and observing proper polarity. Only one set of speaker level inputs can be utilized and assigned by the selector switch.

Set the switch to Primary or Secondary.

Only one type of input (speaker or line) should be assigned to each line. For typical connectivity, do not set speaker input switch to Primary and make connections to the Primary line input.

Note: If there are two inputs assigned as Primary (Speaker and Line) the Line input will take priority.

Typical Connections

Primary /	n/a	Primary if signal present
Secondary		Secondary if no Primary signal
Primary	Secondary	Primary if signal present
	/ Secondary	Secondary if no Primary signal
Secondary	Primary	Primary if signal present
	/ Primary	Secondary if no Primary signal
