using XLR on VTF 15
1. If I use XLR do I need to use both the righ and the left channel inputs or one would do as my Parasound Halo Integrated only has one XLR output for Subwoofer
2. I have separated my HT from 2 channel listening , the question is if I connect the VTF -15 with" one" receiver via XLR and the "other "pre amplifier with with RCA inputs , but only listen to one or the other , not both at the same time in other words I turn one system off and use the other would that work ?
