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.
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.
