A:Answer While the Link 300 's power adapter is set to auto-volts which you can use in 220V regions,if the JBL Link 300 is bought from a different country, a message will show up that some features that are specific in the current location may not apply. In terms of using the Link 300 as a speaker is not available as you can only command it to do things and if you cast it to your TV, It will send the signal to your TV and the the speakers will play.
