SDB-4.1 4 Pair, Dual Source Speaker Selectors with Volume ControlPlease Note, many of these listed on ebay do not include the speaker wire plugs that go into back of the unit, ours does! 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-4.1 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-4.1 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-4.1 is equipped with internal jumpers to select the degree of impedance matching based on the impedance of your speakers and your amplifiers impedance requirements.
