Bose® Lifestyle® SA-3 Amplifier Specifications
- Room selector switches assign the amplifier to a specific room and radio frequency remote control.
- Auto-sensing auxiliary input: Allows external audio sources (a TV or DVD player, e.g.) to play through Bose speakers located in the same room, automatically.
- Once the auto-sensing feature is activated by the user, the SA-3 amplifier automatically switches to the local source when the local source is turned on. (This can also be achieved manually by pressing the "Local" button on the Lifestyle® system remote control.)
- Mini-DIN expansion input and output easily connects multiple Lifestyle amplifiers to the Lifestyle R media center in a daisy chain, whenever two or more pairs of speakers are desired in a specific location (for example, outdoors or in a large hall).
- Wired Volume Control (VCA) input provides connection for an on-wall volume control (can be used with or in place of a Lifestyle radio frequency remote control).
- Finned cast-aluminum housing dissipates heat efficiently for lower operating temperatures, even at full output.
- Integrated mounting flanges allow for permanent mounting to walls or floor joists, if desired.
- Bose® expansion cable allows for a single connection of the amplifier to the Lifestyle R media center or multi-room interface.
- Dimensions: 4.25"H x 14.12"W x 5.5"D (10.7 x 36 x 13.8 cm).
- Weight in carton: 11.1 lbs.(5.02 kg)
- Power rating: Two-channel stereo operation, 100 watts (minimum) per channel.
- Speaker impedance: Compatible with speakers rated 6 ohms or higher.
- Color: Black.
- Limited one-year transferable warranty remains with the system even if ownership passes to another person.

Product Q & A
Hi, is the SA-3 amplifier is multi voltage, i.e. 110V-230V? and can be used outside of the US in a 220V environment with the corresponding 220V power cord? Your response is appreciated.

The Bose® Lifestyle® SA-3 Amplifier is U.S.A. based and has is only 110V. Thank you for your question. If you have any further questions, please contact our customer service experts at 1-866-224-6171. Have a great day! Thursday, August 30, 2012 10:28 AM
I want to expand my Lifestyle 25 into Zone 2 using a speaker selection switch that allows me to send output to one or all of 9 rooms. Room speakers are 8 ohm controlled by an impedance matching volume control. Is this amp sufficient to drive this system using output for background music - not high volume sound like a home theater. I successfully used an old Technics receiver rated at 60 watts per channel to perform this same function.

Answer by a Your Electronic Warehouse Expert
The Bose® Lifestyle® SA-3 Amplifier does not work with speaker selectors. YEW suggests using a stand alone amplifier, such as the Niles Audio SI-1230 or the SI-275 with a speaker selector. Please call 1-866-224-6171 for more details or questions. Thank you for your inquiry.

Lifestyle SA-3 Amplifier. Thank you for your inquiry. Tuesday, November 29, 2011 05:34 PM
