No. I asked a simple question - can the XLR or RCA outputs be turned off?
@dennyboy suggested I turn the subs off from my remote. Given that we were taking about the SU-9n and its remote, you would presume he meant its remote. Maybe the volume of the RCA and XLR outputs can be operated independently of each other. Who knows? There is no logic in him presuming my subs have a remote - of course they don't. So I asked him for clarification, but none was forthcoming. And so other people got confused too. Thread pollution. But as no one has answered yes, I can only conclude that no, you cant turn off XLR or RCA outputs. Pity. Such a simple question, so hard to get an answer, so much confusion. Sorry about that.
