Expert 140 Pro Sub Out without Preamp Ouput

[Waiski]

Biggest problem is that digiout is fixed output.

I think I can tackle that with the sub amp volume control, but that’s a good point.  


Regarding subs with built in DACs, I believe they exist.  But Sadly that’s not on my Zu subwoofer.

Of you can live with this limitation, then I don`t see other problems.
