iPad used with L1 model 1S and Compact
This is just for information.
I use an iPad Air for my Backing Tracks with the StageTraxx App. Just recently updated iOS to 12.3.1. A week later I used my Compact and was experiencing loud bass booming notes during the playing of my BT's. My first investigation was to set up my L1 model 1S but found it was the same, my BT's were sounding awful.
I then re-synced all my BT's to my iPad from iTunes but it still sounded shocking then tried all sorts of things checking my settings but was still stumped spending lots of time on it.
I left it for a few days to ponder over and the thought occurred to me to do a reset of settings on the iPad in 'GENERAL'. Thankfully this restored it back to normal so......it's never happened before on updating iOS but I have to put it down to installing the 12.3.1.
I had the benefit of owning two Bose products so this eliminated me suspecting any problem with my L1 and Compact which can be costly.
