I just set up my B50 a couple of days ago and really like it so far. It is connected to my TV via HDMI (ARC), driving two Micca OoO bookshelf speakers.
When connected the TV via the HDMI speakers, the output volume from the speakers is plenty loud – working fine/as expected.
However, when connected to my iPhone via Bluetooth to play music (typically via the iOS Music app), the volume level is quite low. When my iPhone volume is set to 50%, I can barely hear the music from the B50 and I have to adjust the volume to at least 75% to hear the music (very quietly).
I have looked at the iPhone audio settings to turn off “headphone volume” protection, etc. but haven’t found a culprit/solution yet. I also “forgot” my Bluetooth connection to the B50 and re-paired with no improvement.
I am hesitant to update the firmware (to 52-452f344c) of this unit (currently 50-0ce1e3ac-8) because of other comments in this forum regarding the firmware updating negatively impacting HDMI/ARC behavior, since HDMI/ARC for TV is my primary use case.
Is the preamp(?)/volume path via Bluetooth just very low for some reason?
Any suggestions about something I am missing would be appreciated. Seems like there must be a setting/option on my iPhone or the amp that I just haven’t found yet.
Thanks!
