Dynaudio Sub 6 and C1 Signatures to Musical Fidelity Nu-Vista 800


I have an Oppo BDP-95 which has XLR out.  The Musical Fidelity Nu-Vista 800 has XLR in.  Dynaudio Sub 6 has XLR in/out.  Where in the signal path do I add the sub?  Oppo to Sub6 to MF800?  But if I connect a bluetooth source to MF NuVista 800, then I don't get the Sub6 in the signal path?  Appreciate any help.

Use the rca pre-out from Musical Fidelity Nu-Vista 800 connect to Dynaudio Sub 6 unbalanced rca input, so your subwoofer output level will be controlled by the MF 800 volume control.
