Bose® SA-4 Owner's Manual

Setting up the System

Installing the SoundTouch™ SA-4 amplifier

Locate the SA-4 amplifier indoors, close to an AC (mains) power outlet. It does not 

need to be close to your speakers. 
The SoundTouch

™

 SA-4 amplifier weighs 11 lbs (5 kg). It can be placed on a floor, 

on a shelf, or mounted on a wall. See page 30 for wall mounting instructions. 
Consider the following caution statements when selecting a location for your  

SA-4 amplifier. 

CAUTIONS:
•  The SA-4 amplifier 

must be used indoors. It is neither designed nor tested for 

use outdoors, in recreational vehicles, or on boats.

•  DO NOT mount the SA-4 amplifier on a surface that is not sturdy enough,  

or that has hazards concealed behind it, such as electrical wiring or plumbing.

•  The wireless adapter connects to the SA-4 amplifier with a 6 foot (1.8 m) cable. 

Place the SA-4 amplifier so that the wireless adapter is within range of your  

Wi-Fi

®

 router or network access point.

•  Place the SA-4 amplifier and wireless adapter in an area where the maximum 

ambient temperature is less than 104°F (40°C).

•  For optimum performance, place the SA-4 amplifier in a well-ventilated area.
•  DO NOT place the SA-4 amplifier in a completely enclosed area. If adequate 

ventilation is not provided, the amplifier automatically protects itself by  

reducing its volume level in order to limit its temperature.

•  DO NOT place the SA-4 amplifier on any heat-sensitive surface, such as the 

finished surface of fine furniture. Like all electrical equipment, it generates  

some heat.

•  DO NOT use the SA-4 amplifier in a damp location. It is important to prevent 

moisture from getting into the system.

Installing the SoundTouch™ wireless adapter

The SoundTouch

™

 wireless adapter provides the network input for the  

SA-4 amplifier. It must remain in range of the Wi-Fi router, and within  

70 feet (21 m) of the SoundTouch

™

 controller. 

To keep interference to a minimum and to increase the strength of the Wi-Fi  

signal, install the wireless adapter outside of and away from metal cabinets,  

away from other audio/video components, and away from direct heat sources. 
See page 32 for wall mounting instructions.

Note:  If you experience interference with your network connection, place  

the SoundTouch

™

 wireless adapter outside of any cabinet or enclosure  

and away from metal objects. If problems persist, see “Troubleshooting”  

on page 24.
