Hi Ted,
Is there something I can reference for the "scale" of the microphone gain? People on the other end of the call say there's still a slight echo (better with the 15.1 firmware), and I recall you mentioning to turn down the gain. I don't think it's a 1-10 scale, right?
I'm still amazed at the improved sound quality of the BlueBus, makes me consider upgrading the speakers now. Thanks again for developing this.
