I’ve often wondered why most online info on the Beosound Core indicates that it can only receive incoming source material over Wifi.  I have a BS Core connected to a Beomaster 4400 as Tape 2 input and connected Tape 1 output to the BSCore input minijack.  With Tape 1 set to record, the monitor signal is routed to the Core input and from there Multiroom works fine for broadcasting vinyl, tape or CD (via a Niles TSB-3 selector) on Tape 2 output. In this case, is the Core just using proprietary B&O Multiroom for broadcasting, or is airplay involved? Thanks in advance for any clarification. Joe M in WV USA
