High-power 4-pair speaker selector with volume control
Our take on the Russound SDB-4.1 by Crutchfield's Tara W.
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.
This transfer box is the perfect thing. At least for what I wanted to do. I had two different systems that I wanted to switch between my speakers. Each unit is 150 watts so I felt this unit would handle things perfectly and it has.

Russound SDB-4.1 Reviews
Average Customer Review(s):
Thanks for submitting your review
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.
- Power Handling:
- 200 watts per channel RMS continuous
- 400 watts per channel average
- 600 watts per channel peak
- Volume Control: 42 dB attenuation, 12 positions
- Impedance Matching: Russound Ultra-Match Autoformers
- Weight: 9 pounds

Great product for my application [ Michael Aug 28, 2016 ]
Purchased a home with Russound speakers installed in 4 rooms. The amplifier/selector was sold by previous owner. Needed to hook up speakers to amplifiers/receivers in my media room. [ J Apr 19, 2016 ]
