Your favorite music. At your fingertips.

The SoundTouch™ controller has a unique design that beautifully combines form and function. The intuitive controls give you immediate access to your music, so you don’t need to use your smartphone, tablet or computer.

Convenient control

You can adjust the volume, skip or pause songs, and turn your SoundTouch™ system on or off, from across the room. For added convenience, set up a wall-mounted cradle with the included bracket to put the controller anywhere you want. There’s a magnet in the bracket to keep the controller safely in place.

Easy to set up, easy to conceal

It’s easy to connect the SoundTouch™ SA-4 amplifier to your choice of speakers. And, with its compact design, it’s small enough to be easily hidden away on the floor or a shelf. You can also mount it to a wall. Once connected, you’ll enjoy streaming music at the touch of a button. Anywhere around your home.

Powerful SoundTouch™ app

The SoundTouch™ app gives you all the control you need to access music on your system. Use it to drag and drop any music source—a favorite Pandora station, a playlist, Internet radio—to your six presets. Now they're just a touch away. But when you want to venture beyond your presets, use the app to stream any song or station directly from a computer, smartphone or tablet. Browse the online musical universe or your own music library to your heart's content. And with more than one SoundTouch™ system in the home, you can use the app to play the same music everywhere or play different music in different rooms.

Can I connect the SoundTouch™ SA-4 amplifier to my existing Bose® speakers?

Most passive stereo speakers will work with the SoundTouch™ SA-4 amplifier. These include 151® environmental speakers, 251® environmental speakers, Free Space® 51 environmental speakers, 161™ speaker system, 201® Direct/Reflecting® speaker system, 301® Direct/Reflecting speaker system, Acoustimass® 3 Series IV system and Acoustimass 5 Series III system. The Bose 901® speakers are active speakers and therefore will not work with the SoundTouch™ SA-4 amplifier.

How do you control the SoundTouch™ SA-4 amplifier?

There are two ways to control the SoundTouch™ SA-4 amplifier. You can use the SoundTouch™ controller, included with the product, or the free SoundTouch™ app on your computer, smartphone or tablet.

Can I connect to speakers from other manufacturers?

Yes, minimum 6 ohms impedance.

How many speakers can an SA-4 amplifier power?

As with our current Lifestyle® SA-3 amplifier, it should generally power only one pair of speakers (rated at 6 ohms minimum) to ensure the optimal experience. However, it is possible to reasonably power more than one pair, depending on the speakers used. In any case, all attached speakers will work together as one SoundTouch™ “zone.”

Can the SoundTouch™ SA-4 amplifier be used outdoors?

No. The SoundTouch™ SA-4 amplifier is neither designed for nor protected from placement that may expose it to rain, condensation, ice, salt water, extreme heat or other weather conditions. It can be used with outdoor speakers, but must be placed inside while the speakers are outside.

Where should the SoundTouch™ SA-4 adapter be located when installing the SoundTouch™ SA-4 amplifier?

We recommend placing the SoundTouch™ adapter within one wall or floor of the room where the speakers and SoundTouch™ controller are used. Also, the SoundTouch™ adapter should never be placed in a metal wall panel or cabinet. The SoundTouch™ adapter can be placed in a non-metal entertainment center, like one made of wood.

Can multiple SoundTouch™ SA-4 amplifiers be installed in an amplifier rack?

Yes. It is possible to install multiple SoundTouch™ SA-4 amplifiers in an amplifier rack, but the SoundTouch™ adapter(s) should be installed outside of the rack to prevent interference.

What if I need a longer cable to connect the SoundTouch™ SA-4 amplifier to the SoundTouch™ adapter?

Bose offers an extension cable of 25 ft. Contact Bose to purchase this accessory if necessary.

Can you daisy-chain multiple SoundTouch™ SA-4 amplifiers together?

Yes. Using the Bose® link output, you can daisy-chain multiple SoundTouch™ SA-4 amplifiers. However, in this case, the products will act as a single zone, meaning the SoundTouch™ amplifiers cannot be independently controlled through the SoundTouch™ app or SoundTouch™ controller. When multiple independent zones are required, each SoundTouch™ SA-4 amplifier needs to have its own SoundTouch™ adapter, so daisy-chaining is not possible.

Can the SoundTouch™ SA-4 amplifier’s Bose link connector be used as a traditional extension?

No. The power supplied over the SoundTouch™ SA-4 amplifier’s Bose link port has been increased to be able to power the SoundTouch™ adapter. As a result, it is not compatible with legacy Bose link products upstream (e.g., a Lifestyle® 48 system). For these legacy applications, continue to use the Lifestyle® SA-3 amplifier, which will continue to be produced for some time.

Which Bose® products are compatible with the SoundTouch™ SA-4 amplifier?

The Bose SoundTouch™ SA-4 amplifier works with the Bose indoor and outdoor speakers, as well as most other speakers.

Do I need to connect the SoundTouch™ controller to my Wi-Fi network?

No. The SoundTouch™ controller does not connect to a Wi-Fi network. Instead, it connects directly to a SoundTouch™ system using Bluetooth® low energy technology.

Can I use several controllers to control the same system?

No. Only one SoundTouch™ controller can be paired to a system at one time.

What is the range of the controller?

The range of the controller is approximately 70 feet from the paired system in wood-construction homes. In concrete, stucco or brick homes, the range will likely be less and may vary. The number of other active wireless devices in the house may affect range as well. You can also use the controller outdoors, but you shouldn’t leave it exposed to the elements or mount it outside of your home.

What if the range is not enough?

For most SoundTouch™ products, there shouldn’t be a range issue: the system the SoundTouch™ controller is paired to is usually in the same room. The exception is the SoundTouch™ amplifier, which is mounted often in closets, basements or attics. If the range is not sufficient to reach the amplifier, we recommend using Bose® link extension cables to wire the SoundTouch™ adapter to an area within one wall or floor of where the controller is located.

Can I mount the SoundTouch™ controller to a wall?

Yes. It can be mounted anywhere indoors with the included wall-mount bracket. The SoundTouch™ controller magnetically attaches to the wall mount so you can easily take it when you need it. The magnet is in the wall-mount—not the controller—so for example, you cannot attach the controller to a refrigerator.

How is the SoundTouch™ controller powered?

The SoundTouch™ controller is powered by four standard AA batteries. With typical usage, they should last 6 – 12 months.

How will I know when to replace the batteries?

When the batteries get below a certain point, the controller’s OLED display will indicate that it’s time to replace them.
