More details on the Russound SDB-2.1
Overview: The Russound SDB-2.1 is a dual source speaker selector that allows you to control two pairs of speakers. The front panel has separate volume controls for each speaker pair so you can adjust the volume in each room from one convenient location. At each volume control, you can turn each pair of speakers on or off, and select amplifier A or B using the two 2-position push-buttons on the front panel.
Ultra-Match Technology: The SDB-2.1 uses high quality impedance matching autoformers that distribute maximum power throughout the system while maintaining a safe operating load at the amplifier. You can use the speaker selector with 4- or 8-ohm speakers. Internal jumpers allow you to select the degree of impedance matching for your speakers and amplifier.
Note: The unit is set at the factory at 2x, which is proper for most applications. If certain applications require changing the impedance setting, you will need to remove the cover and reposition the jumper on the autoformers.
Volume Controls: The SDB-2.1 has two rotary volume controls with 11 steps of volume, plus an off position. The volume control provides a total of 42 dB attenuation.
Connections: The speaker selector features four 4-pole screw terminal blocks, two for the inputs from the amplifiers, and two for the outputs to the two speaker pairs. The terminals allow you to connect up to 12-gauge speaker wire. The terminals can be unplugged from the volume control for easier wiring.
Room Labels: The SDB-2.1 comes with a sheet of non-adhesive room labels which slide into a groove in the front panel. A total of 52 labels and 8 blanks are included.
Performance: The unit will accept up to 100 watts RMS per channel (300 watts peak).
