Overview: The Russound SDB Dual Source Speaker Selector is a
high-power, dual-source, autoformer-based speaker selector with individual
volume controls for 6 rooms or areas. Dual-source operation allows you to choose
either one or two different amplifiers or receivers to power selected speakers
independently. Each room has its own input selector (A-B), volume control, and
on/off switch, located on the front of the unit. The unit works with all
speakers rated from 4-8 ohms and amplifiers rated for 4-8 ohms.
The SDB-6.1 has the following front panel controls:
- Volume Control: six rotary volume controls, each with a 12-step
- On/Off Switch: six 2-position push button switches (Out=Off,
- Amplifier Selector: six 2-position push button switches (Out=Amp
A, In=Amp B)
Terminals: There are six removable 4-pole speaker output terminal blocks and
removable 4-pole speaker input terminal blocks, each of which can accept up to
12-gauge wire. The terminals can support multiple speaker pairs wired in
parallel or series, provided their combined impedance is a minimum of 4 ohms. A
small slotted screwdriver is required for attaching the terminals to your
Impedance Setting: The impedance of the autoformers is set at
the factory at 8x. A chart in the Installation Manual can help you determine the
proper impedance setting for the number and impedance of your speakers. If
certain applications require changing the impedance setting, the cover can be
removed to access the jumpers inside.
Labels: There are 52 pre-printed and 8 blank label stickers
included for easy identification of the front panel controls.
