Hi All,
Sorry if this has been covered somewhere else....I have recently been using my LT in studio rehearsals and noticed a low level hum when connecting via XLR....I have seen all the chat re xlr & phantom power, but that is not the issue...all my presets have a return block for adding my BOSS BR80 into return 1, so I can use backing tracks for practice. However, this block is causing "hum" even with nothing connected to it. The "hum" goes away when I remove the return block.....does anyone know why this is happening...? I don't really want to double my presents with / without return loop if possible ...
Thanks
