Hello there. I am very inexperience with audio stuff so I might end up trolling myself without knowing it.... I decided to use my father's ancient amplifier which works fine when it is in casete or vinyl player) but my phone won't recognise the amplifier.
It confuses me cause we are talking for pure analogue (voltage signals) without any digital protocol and such.
Do you have any idea what can I do for this?
Thanks for your time
