Russound SDB-2.1 - Dual Source Two Pair Impedance Matching Speaker Selector with Volume Control

Dual Source Two Pair Impedance Matching Speaker Selector with Volume Control
Description

The most important and most forgotten about subject in getting reliable and high quality distributed audio is arguably impedance matching...Forget these fundamentals and you will open up a host of issues!

The SDB-2.1 is a highly efficient dual-source speaker selector that controls two 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-2.1 allows you to choose a separate 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-2.1 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-2.1 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.
