SoundTouch Wireless Music System: The SoundTouch SA-5 is part of the Bose SoundTouch wireless music ecosystem which allows you to play music throughout your home.

According to Bose' support site, this SA5 amp can will work with any computer that can run Windows Media player. Your Windows 10 OS computer is expected to work
[ Paul  Mar 29, 2021 ]  Staff
I have a Bose Soundtouch SA5 and would like to install three individual 'Virtually Invisible 591' ceiling speakers in a long room. I guess it will be one pair and one individual speakers. Will this be possible or do I have to install them as pairs only, i.e. two or four speakers?
[ Hendrik  Dec 20, 2020 ]

You should be able to do this without any problems at all. I connected to speakers and a sub woofer and it worked just fine.Enter an answer to this question.
[ Joel  Jan 15, 2021 ]
Hello, i belive is posible, you can install up to 4 speaker, 2 pairs. In your case you can instal 1 pair and another extra on the other pair slot. The only problem i see is that the individual speaker will be either R or Left channel, most likely will not be playing all the sounds
[ Jose Rivera  Dec 20, 2020 ]
[ FRANCO S  Dec 20, 2020 ]
I have my sa5 set up as a 2 pair because there is no center channel input if you were to link a single to the other input it would throw off stereo/hd output and sound off tone with certain songs ect. My advice definitely try to get the pair
[ John  Dec 20, 2020 ]
I have 5 sets of 2 speakers. Can I run 5 zones from this amp and control which zone is playing from my phone?
[ Michael  Aug 19, 2020 ]
2 answers
No. This system will be only one zone... You can conect up to 4 speakers to it!! but is is only one zone. The amp has multiple inputs( bluetooth, wifi,3 auxiliary inputs), with the soundtouch app you can change the input from the zone and control volume etc, it the amp is only one zone. Hope this help
[ Jose Rivera  Aug 19, 2020 ]
No, you only have 1 zone with 2 set of speakers and no control of the speakers.

will the Bose SoundTouch SA-5 stream audio from apple tv 4?
[ Cory  Apr 24, 2020 ]
5 answers
AirPlay 2 is now Integrated with the SoundTouch application. I believe this should work for you.
[ Joel  Apr 25, 2020 ]
It should through a Bluetooth connection
[ John  Apr 24, 2020 ]
Yes.... Wireless it has bluetooth and you can connect that way. By Wire yo can hook up your apple tv to the tv. via hdmi and the tv via any of the auxiliary that Sa-5 has, optical or rca... works without problems either way
[ Jose Rivera  Apr 24, 2020 ]
No not directly from Apple TV, but it will stream your smartphone via bluetooth which you could have Apple TV app on your iPhone. Its best streaming feature is built in Bose app "Soundtouch" you can operate from your smartphone and app has Amazon Music, Deezer, iHeartRadio, Pandora, Spotify, SiriusXM and TuneIn apps available as of today. The great thing about this app is its standalone, so once you get it playing you can turn off or do whatever with your phone because its streaming direct via internet connection not dependent on the range of your smartphone.
[ GREG  Apr 24, 2020 ]
You would need to make a cable that has an HDMI one end and rca jacks on the other to make it work.
[ thomas  Apr 24, 2020 ]
Can I use the SA5 and my Bose Portable Home Speakers (wifi) to work together and play the same music from my iphone? Thanks in advance!

Their SoundTouch products can operate together, yes. The SoundLink will not sync up with the Soundtouch though.

Can this item be retrofitted to work with my bose lifestyle model 20 system?
[ JAMES  Mar 20, 2020 ]
1 answer
No that Bose Lifestyle 20 system uses proprietary connectors as well as the Lifestyle Music Center and Acoustimass Module which will not work with the Bose SA-5 amplifier.
[ Cosmo  Apr 08, 2020 ]  Staff
With a pair of speakers attached to the A speaker output of the SA-5, can I wire both B speaker channels to a single dual terminal center channel speaker?
[ Quinton  Mar 11, 2020 ]
1 answer
It wouldn't get you surround sound, as the SA5 will output the same audio to both the channels. If the impedances are within spec, it should work.
[ William  Mar 12, 2020 ]
Will this work with 901 Series and Active Equalizer?
[ Max  Jun 07, 2019 ]

I think they will but don't know if there's enough power to push 901 speakers

Can the SA-5 be used to power some rear in-ceiling speakers with a sound touch 300 Soundbar?
[ Donald_A  Nov 23, 2018 ]
1 answer
Sorry, no. The SA-5 is great for powering stereo speakers in a multi-room application but cannot be used for powering wireless surrounds with the ST300.
[ Ryan  Nov 28, 2018 ]  Staff
can you add this to the soundtouch 300 bar to use for tv speakers? I currently have the soundtouch 300 and acoustimass 300 hooked up to my tv, the sound is great but I have in-ceiling wired speakers from my previous system that I would like to use. Would this be the answer to my problems and could I link all these together not only for my tv sound but for music and entertainment as well?
[ Joel G.  Dec 30, 2017 ]
1 answer
Sorry, no. The HDMI and optical inputs of the SoundTouch 300 Soundbar cannot be shared with other SoundTouch devices (like the SA5 amplifier). If you want to add some wireless surrounds, you can use the compatible VI300 but these have built-in speakers are would not power your in-ceiling models:
[ Ryan  Jan 05, 2018 ]  Staff
Can the SA-5 amp be linked to the Bose SoundTouch 300 via Bluetooth or other so that whatever is playing through the 300 may be heard through the SA-5 speakers?
[ James  Nov 07, 2017 ]
2 answers
Yep! As Robert alluded to above, all of the Bose SoundTouch components have the ability to play the same song simultaneously; or you can choose to play different songs through each individual Bose SoundTouch component in your home. For more details or to discuss further, please contact an Advisor directly by phone (888.955.6000) or online chat. Thanks! :)
[ Larry  Nov 13, 2017 ]  Staff
All sound touch devices that are on the same network can be linked to play the same thing. The amp can also play via blue tooth or aux, but I? dont think Bluetooth and aux connections will not "back feed" via WiFi to the other devices on your sound touch system.
[ Robert  Nov 07, 2017 ]
will this work with soundtouch 30 series III System?
[ AntoniCm1983  Jun 13, 2017 ]

You will have to download the bose app on your phone but once you do that you can link them both together to play the same music.

I Don't know
[ John  Jun 13, 2017 ]
Does this go to sleep automatically or remain powered on? The other sound touches (20 &30 do go into sleep after 20 min)
[ Foxknows  Apr 12, 2017 ]
1 answer
I'm afraid there's no specific mention of an "auto" power off feature for the SA-5 in the specs or owner's manual. Given that there is no physical on/off switch or button on the amplifier itself, it is very likely that it will automatically shutdown after a given time period of no music playing through it (like the other SoundTouch speakers); but if you'd like to find this out for certain your best bet is through Bose directly. You can call them at 800-999-2673 or check their support site:
[ Larry  Apr 19, 2017 ]  Staff
I have 8 Bose Free Space 51 Outdoor speakers (100W/8ohm). It appears I can use 2 of these amps will push 100 watts to each of the 8 speakers. How do I get the music to stream from my iPhone to both of these amps simultaneously? Do I sync the iPhone to each amp separately via Bluetooth Seems like there would be potential for lag or other issues.
[ Scott  Apr 08, 2017 ]

Let me explain my previous answer.. I have along with the speakers the Bose amps to push my system. The app interfaces with the amp not the speakers....
[ Jacob  Apr 08, 2017 ]
Download the Bose app. In the app u can control all or just one amp at a time and is where you would also stream music from.
[ Jacob  Apr 08, 2017 ]
Once connected to one of the amps, use the app to have the second amp play what the first one is playing. You cannot connect to both simultaneously via Bluetooth.
[ Robert  Apr 08, 2017 ]

can I connect like some type of mic or a way to do karaoke through this system?
[ jose  Jan 18, 2017 ]
1 answer
The Bose SA-5 offers no option for connecting a microphone for Karaoke. For that, you may want to consider a system like the Singtrix Party Bundle: While I know this isn't the answer you were looking for, I hope the information helps.

Can this Amp be used with non-Bose speakers?
[ Clay  May 03, 2016 ]
2 answers
My understanding is yes. I have not hooked mine up yet but the information from Bose is that they will work on any speakers as long as the oms match is correct. I will be using this amp with non-Bose and Bose speakers. You can determine this by looking on the back of your speakers and following the installation instructions from Bose.

Will this unit support 4 bose speakers and a sub woofer I already have?
[ Carl  Apr 16, 2016 ]
1 answer
You can wire up to four speakers to the amp (each speaker must be a minimum 8-ohm impedance), but there's no dedicated subwoofer output on the Bose SA-5 amplifier so your subwoofer must accept speaker-level inputs in order to work with the SA-5. I hope that helps. My Bio:

Do you need a wifi network for this receiver to work? (wanting to use this out at the lake where wifi is banned)
[ mdside  Apr 07, 2016 ]
1 answer
Yes. You need a Wi-Fi network in order to control the player with the Bose APP and to stream audio content from your home network and online music services. While the SA-5 also features Bluetooth, it must be connected to a Wi-Fi network initially for setup and updates before you can pair any Bluetooth devices. I hope that helps! My Bio:

Can you switch between speakers A and B? If so, can you do it from the app, and lastly, can you play A and B at the same time?
[ Ryan  Feb 10, 2016 ]
1 answer
The amplifier can only broadcast one input at a time to all speakers attached. What is broadcasting on speaker A will be the only thing available on B. If you want different music you will have to by another amplifier.
