Mackie FreePlay LIVE

The speakers' sound is great and the app to control them is intuitive to use. Sadly the linking of two units is mis-leading Mackie Sales quote 'You can also link a second FreePlay speaker wirelessly for an even larger (stereo) sound.'
I contacted BAX because I couldn't get it to behave as stereo whilst using the mic/line inputs. BAX tried to help and then said one of their technicians would call me back. They never did and so I battled on which is when I discovered that the linking feature only allows the streaming of bluetooth audio to be sent to the other speaker.Not any of the m,ic/line inputs. I real shame and I don't know why it doesn't work as it is a common feature used in domestic sound bars and Sub woofers in TV setups.
