None of the responses to this forum will work.
Until Bose creates an app for AppleTV you can ONLY wire the speakers to work together. You need a specific cable for the second speaker. I searched on Amazon and found one that works for about $15. But you can get it from Best Buy or any large electronics or Music equipment store. Search for either of the following criteria:
1/8" to 1/4" Stereo Cable. OR
3.5mm to 1/4" Adapter Stereo Audio Cable
- Once you have your cable, pair one of the S1 Pro speakers to your AppleTV via Bluetooth.
- Plug the ¼" end of the cable to the back of the paired speaker where it says "LINE OUT"
- Then use the ⅛" end of the speaker cable to the AUX input on the second speaker.
You may want to get a really long cable for good separation of the two speakers. About 7' to 10' should be fine (depending on the size of your room). That should do it!
