So
Living: BV 5 (5.1) OPT 2 with BS3200 OPT 0, via AUX BSEssence 1st Generation.
Playroom: BSy3 (5.1) OPT 6 with BS5BM5 (Audio Master NO = Off) if you connect USB Behringer you can listen Spotify BC4 N.MUSIC Go 1 and AUX (Airport Express Airplay) BC4 N.MUSIC Go 2.
Could you give me the model and how to connect it to BM5, it works without problem?. (It;s the firs time i heard about USB Behringer. I suppose only you can listen in Playroom. but its very interesting.
