Hello,working bluetooth mode in B50 ,Master volume is volume sound
smartphone and put a 3/4 not much volume general,in mode Phone ,Line aux,have more volume overall.
When I move control volumen in B50 ,in my smartphone also moves at the same time control volume.
Did you ever find a fix for this? i am on the verge of sending mine back because of this exact issue.
I have got firmware v63 from support (I had an issue which was reported here in this forum for v60 about quite volume then “explosion” of sound) and I observe opposite behavior - BT in RX mode is very loud (much louder than other types of inputs). But… TX BT is opposite - sound in headphones is quite quiet…
