Features

Overview: The Russound SDB Dual Source Speaker Selector is a high-power, dual-source, autoformer-based speaker selector with individual volume controls for 4 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.

Controls: The SDB-4.1 has the following front panel controls:

  • Volume Control: four rotary volume controls, each with a 12-step adjustment.
  • On/Off Switch: four 2-position push button switches (Out=Off, In=On)
  • Amplifier Selector: four 2-position push button switches (Out=Amp A, In=Amp B)

Removable Speaker Terminals: There are four removable 4-pole speaker output terminal blocks and two 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 speaker wires.

Impedance Setting: The impedance of the autoformers is set at the factory at 4x. 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.
