I received my 1.5 yesterday 9/1/2020….and immediately noticed something not right,i am using both speaker outs and a line out….2 problems,it doesn`t matter which dip setting i use,…off ,on on,….or off,off,off…..or off on,off……neither does the external olume control has any effect….and i hear a pop noise every time a song turns on….. i do not hear the pop noise on speaker out….but i do hear it on line out…..pop before a song starts….
external volume control does not work….tried different settings…
