Russound SDB-6.1 Speaker Selector

The SDB-2.1, SDB-4.1 and the SDB-6.1 are high-power, dual-source, autoformer-based speaker selectors with individual volume controls for 2, 4 or 6 areas/rooms. Dual-source operation means either one of two different amplifiers/receivers can be chosen to power selected speakers independently. For example, you can choose to listen to jazz music in a couple of rooms and classical music in all the others. Each room has its own input selector, volume control and on/off switch, located on the front of the unit. The SDB speaker selectors work with all speakers rated from 4 to 8 ohms, and amplifiers rated for 4 to 8 ohm loads.

The SDB-6.1 is a highly efficient dual-source speaker selector that controls up to six pairs of speakers. The front panel provides a separate volume control for each speaker pair, allowing you to adjust the volume in each room from one convenient location.

With two amplifier inputs, the SDB-6.1 allows you to choose either program in each room. Each zone also has an on/off switch, which allows you to keep the volume control at a set level while turning the speakers on or off.

The SDB-6.1 uses high-quality impedance-matching autoformers to maintain a safe operating load at the amplifier while distributing maximum power throughout your system. Designed for use with either 4- or 8-ohm speakers, the SDB-6.1 is equipped with internal jumpers to select the degree of impedance matching based on the impedance of your speakers and your amplifier’s impedance requirements.
