But i'm a little bit estonished that the powerlink connection at the BL3500MK2 only works with a transmitter.. hm, we will see.
This is because it is not made to use as the main speaker and was usually used in another room as part of a Masterlink setup. The Wireless 1 transmitters are simply a "wireless" Beolink Active which is Masterlink in - Powerlink out.
Hopefully you get lucky and can make it work with Powerlink but it will definitely connect to your BS4 with Masterlink.
