Our take on the Bose® Lifestyle® SA-3 stereo amplifier

by Barry Montgomery
Bose

Bring great Bose sound to any room in your home. The Bose Lifestyle® SA-3 amplifier lets you quickly and easily expand a Lifestyle® home theater system into a multi-room/multi-source system. That means you can enjoy surround sound in your home theater room while other family members tap into the music-playing features of your Lifestyle® system in other rooms, or even outdoors.

The Lifestyle® SA-3 amplifier is the most powerful stereo amplifier Bose offers. With 100 watts per channel, it can drive any pair of high-performance Bose speakers you choose. The Lifestyle® SA-3 amplifier also offers patented Bose signal processing circuitry that automatically adjusts tonal balance as you change volume, guaranteeing that you'll enjoy warm, full-bodied stereo sound at any listening level.

Like all Bose products, the Lifestyle® SA-3 amplifier not only delivers great sound, but also offers simple, streamlined operation. The included Bose link cable is all you'll need to connect the amplifier to your main Lifestyle® system. An expansion remote (sold separately) is necessary to operate the Lifestyle® SA-3 amplifier — this also gives you easy control of your Lifestyle® system from afar.

The Lifestyle® SA-3 amplifier also offers an auxiliary input that lets you hook up an additional piece of A/V gear located in the same room, such as a CD player, a portable audio device, or a TV. An auto-sensing feature allows the amplifier to switch to this local source whenever you turn on the connected component.

This amplifier is small and sleek enough to be easily concealed on the floor, tucked away on a shelf, or mounted to a wall. It also includes an expansion output that lets you "daisy-chain" multiple Lifestyle® SA-3 amplifiers for audio in up to 14 additional rooms.

Features

Product Overview: The Bose Lifestyle SA-3 stereo amplifier allows you to expand your Lifestyle system by adding Bose non-powered environmental speakers outdoors or accessory speakers in another room. An additional remote control (such as the RC18S, RC38S or Personal Music Center II remote) is required to control the amplifier.

Important Note: This amplifier is not designed to be used as a stand-alone amplifier. It is designed to be used exclusively with a Bose Lifestyle System.

Signal Processing: The amplifier features Bose proprietary Integrated Signal Processing technology, providing full, rich stereo sound, even when the speakers are playing at low volumes.

Bose Link Input/Output: The SA-3 has a 9-pin Bose Link input for connecting the output of the Lifestyle system using the supplied Bose Link A cable. Multiple SA-3 (or SA-2) amplifiers can be daisy-chained together by connecting the Bose Link output of one amp to the input of another. With a compatible Bose Lifestyle system you can experience stereo sound in up to 14 additional rooms.

Auxiliary Input: If you wish to plug in a local audio source to play through the speakers in a particular zone, the SA-3 provides a stereo RCA auxiliary input. When the SA-3's micro-switches are set appropriately, the amplifier will automatically detect when the local source is turned on and switch the amplifier to that input.

Advanced Features/Room Codes: The amplifier is equipped with 7 micro-switches: three for setting up advanced features and four for setting up the amplifier room code:

  • Mono/Stereo Operation: You can switch between stereo and mono operation. Mono operation may be useful with outdoor speakers covering a large area.
  • Local Source Auto Detect: With Auto Detect on, the amplifier can detect when the source unit connected to the Auxiliary input jacks is turned on. The amplifier automatically turns on and switches to the auxiliary input.
  • Single Amp/Supplemental Amp Designation: If you are using the amplifier in a stand-alone configuration, you should set the switches for Single Amp operation. If you are covering a large area with multiple amplifiers, setting all but one amplifier to the Supplemental Amp mode allows you to turn all of the amps on/off, mute them together, or change their volumes simultaneously with one remote control. (The 4 room code switches should all be set alike.)
  • Room Codes: When setting up multiple amplifiers for multiple rooms, each room has a unique "room code". The four micro-switches (6, 7, 8, and 9) can be configured for Rooms B through O. The room code on the amplifier should match the room code of the remote used in the room where the speakers are installed.

8-to-9 Pin Adapter: Some Lifestyle systems have an 8-pin Bose link connector. An 8-to-9 pin adapter is supplied to allow you to plug the supplied Bose Link A cable into an 8-pin connector.

Amp Installation: The SA-3 amplifier can be placed on a shelf or tabletop. It can also be wall mounted if you remove the rubber feet and use the guide holes for the mounting hardware. Note: The amplifier weighs 11 pounds, so proper hardware must be used to support the amplifier safely.

Speaker Wiring: The amplifier is equipped with a removable, right-angle terminal block for connecting the speaker wires. The speaker wire, up to 14-gauge thick, is first attached to the terminal block, then plugged into the amplifier. The use of 18-gauge wire is recommended for speaker wire runs of up to 30 feet, 16-gauge wire for up to 45 feet, and 14-gauge wire is recommended up to 70 feet.

Use With Volume Controls: A 2-conductor terminal block connector is supplied for use with local wall-mounted volume controls.

Status LED: An LED mounted beside the room switches provides the status of the amplifier's operations. The LED will glow or blink at different intervals to indicate the amp's current status.

Product Works Great!!!

Written By Brian and Laurie, Jackson, NJ on Wednesday, September 10, 2008
 
Simple product to hook up, works like a dream. I am really impressed with the Bose product sound. Now the kids can watch TV in the family room while we sit by the pool and relax listening to our favorite music selections. If you are looking for a multi-room solution to expand your music listening horizons I highly recommend this product.

From the webpage: connects to your Lifestyle® system with a single Bose link cable (included) If you want to control the volume for this SA-3 independently, the expansion remote will help there.
