Overview

Our take on the Russound SDB-4.1

Here's a convenient way to distribute signals to four pairs of speakers from one location. The Russound SDB-4.1 lets you independently select and adjust the volume for each set of speakers — a necessity for most multi-room systems. This versatile design also allows you to switch between two source amplifiers or receivers. The impedance can be customized to match your specific combination of speakers and sources.

Product Highlights:

  • play up to 4 pairs of speakers simultaneously
  • allows switching between two source amplifiers or receivers
  • autoformers ensure efficient impedance matching
  • each zone features independent volume, power, and source controls
  • power handling: 200 watts per channel RMS
  • accepts up to 14-gauge speaker wire
  • includes room/speaker labels
  • 17"W x 3-5/16"H x 7-1/2"D
  • warranty: 10 years
  • Our 60-day money-back guarantee

What's in the Box:

  • SDB-4.1 speaker selector for four pairs of speakers
  • Sheet of self-adhesive room labels
  • Installation Manual

Expensive. Needed it for receiver power. Works as advertised.

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 14-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.

1 question already asked

Yes I have 8 ohms and I use it in a 8 ohm configuration [ Todd  Jan 13, 2018 ]
This unit can be set for multiple ohm settings. It comes from the factory pre set for most applications. My problem was I was using a set of 8 ohms and a set of 4 ohm speakers which it will do but I found with my particular situation I had to use a substantial higher volume settings then running the individual speakers direct from my amp which is a McIntosh MA6600. Hope this helps. Bruce Pageland, SC [ Bruce H.  Jan 12, 2018 ]
Yes, works fine with 8 ohm speakers! [ Charles  Jan 12, 2018 ]
Sorry, but I have no idea. [ STEVEN  Jan 12, 2018 ]
