SDB Series

Dual-Source

Speaker Selectors

1. Description

The SDB-2.1, SDB-4.1 and the SDB-6.1 are high-power,

dual-source, autoformer-based speaker selectors with indi-

vidual volume controls for 2, 4 or 6 pair of speakers. Dual-

source operation means two different amplifiers / receivers

can drive selected speakers simultaneously. For example,

you can choose to listen to jazz in a couple of rooms and

classical in all the others. Each speaker pair has its own input selector, volume control and on / off switch. The

SDB speaker selectors work with all speakers rated 4 ohms and above.

2. Connections

All SDB models have heavy-duty, removable screw connectors that accept wire up to 12 gauge wire. Connect

the amplifier's output to the AMP A and AMP B connections on the SDB, being sure to follow polarity from the

output of the amplifier to the input of the speaker selector (+ to +, - to -). Connect the speakers to the output of

the speaker selector, again being sure to follow the polarity.

3. Setting the Impedance

The impedance of the autoformers in the SDB Speaker Selectors is set at the factory to be proper for most appli-

cations, however, for certain applications, the setting must be changed. This can easily be done by removing the

cover of the unit and re-positioning the jumpers on the autoformers to the necessary impedance-matching

setting.

Russound SDB Speaker Selectors autoformers can be set to impedance-matching settings of 2X, 4X or 8X. The

SDB-2.1 comes set at 2X; the SDB-4.1 at 4X; and the SDB-6.1 at 8X.

4. Operation

To operate the SDB speaker selector, simply turn on your amplifiers and select a source for each amplifier. At the

speaker selector, turn on your selected pair of speakers and select AMP A or AMP B. Set the volume by rotating

the control clockwise to increase volume or counter-clockwise to decrease volume. The SDB speaker selectors

will allow you to operate any combination of speakers selected to amplifier A or B.
