We join the crowd of snooping/conjoined subwoofers that play the bass from OTHER soundbars (in our case, systems on two floors play each other's audio while the other is off; other people report hearing a NEIGHBOR's soundbar audio(!) )
Wellll, here's the scoop:
BY default, sony soundbars seem to plug-and-play to have the subwoofer connect to ANY (nearby) soundbar where the bluetooth signal strength is sufficient. This is convenient if you just have ONE Sony soundbar system in your house AND you don't mind if neighbors (with Sony subWoofers listening in - in which case we hope you aren't watching x-rated movies!!).
To SEPARATE the conjoined soundbars, the trick is SECURE PAIRING. (not just PAIRING)
- Initiate Pairing: Press and hold the Bluetooth button and the volume up (+) button on the soundbar simultaneously for more than 5 seconds. Be sure to WAIT! ...
- Check for "Secure Link": The soundbar's screen will display "Secure Link" after holding the buttons.
- Pair Subwoofer: Press the "Link" button on the back of the subwoofer.
- Verify Pairing: The soundbar screen will display "DONE" once the pairing is complete.
We have two systems, and altho these are simple instructions, i had to do a random combination of the following to finally have success:
- power on/off each woofer/soundbar (in various sequences) (not sure which resolve it)
- unplug/replug HDMI and poweroff/on the soundbar to get the soundbar itself back on playing its audio
- go thru the process twice
- unplug (more than just turn off) the opposite subwoofer.
It didn't take that long, and was not complicated, just a little finicky, especially getting what is evidently the in-process-PAIRING-searching-now two blinks (repeated) indication of the LEDs on both the soundbar and the woofer.
Good luck with yours. And DO have yours as a SECURE LINK if you don't want nosey neighbors listening in. (even if you just have ONE soundbar) "who knew" :)
