Dali AX1 schematic?

Hi all,

I have a pair of Dali AX1 active speakers for two years..
I use them for TV and phone with BT..
Recently I bought a Teac TN3B turntable and connect it to my speakers aux input.
I may say it's sound is "acceptable".
But one question has been puzzling me ever since I connected them;
Is my Dali's aux input a real analog input or it goes to an ADC then volume control then DAC and finally the amplifier stage..😕
So anybody has a circuit diagram or service manual or some excact information about that ?
Thanks in advance for any kind of helps..
