hey
I need some help in the video i’m demonstrating my issue
first channel is used with the turntable
second one nothing is plugged into

significant humming in the lower end
nothing seems to really fix it

guess the usual ‘noise’ is normal

using a power amp with no additional volume setting
so i play around 9-10 o clock with the master knob just for orientation - is pretty loud

any help appreciated

cheers
