4 Pair Speaker SelectorThe SDB-4.1 is a highly efficient dual-source speaker selector that
controls up to four 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-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 amplifier's impedance requirements.
