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.
