Question

Hello,

Can i connect Blaupunkt GTb8200A active subwoofer directly to Eris 3.5BT considering that I have a 12V source to power the subwoofer and how? Do i need something extra like an audio interface or anything else?

Thanks.

It doesn't look like it.  The Blaupunkt GTb8200A does not appear to have the correct connections for the ERIS 3.5BT.  You should take a look at the ERIS8 sub manual on page 5 for how to use a sub with the ERIS speakers (https://pae-web.presonusmusic.com/downloads/products/pdf/Eris_Sub8_Owners_Manual_EN_03112021.pdf).  
The ERIS8 sub has 1/4" and RCA pass throughs for connecting to the right and left ERIS speakers.   The Blaupunkt GTb8200A has no 1/4" or RCA pass throughs for the ERIS 3.5BT speakers.
