A:AnswerQuoting the user manual-
"The OUT jacks output audio signals of the currently selected input (except when LINE 3 is selected).
Volume level, tone control and balance settings do not affect the OUT jacks"
A:AnswerI don't believe so. You can simply turn on one, both or neither set of speakers. There is just one volume control that affects output to all speakers at once.
A:AnswerI never tried it to connect Sirius xm to Yamaha, but I think you can do it if you have its application on your phone. It's same as you play Spotify or any NPR station.
A:Answer6 OHM speakers will work fine and seem to be the norm these days. When you hook up your speakers in parallel the OHM's drop in half to 3 OHM. However that can vary based on speaker wire length and gauge. Yamaha recommends a min of 4 OHMS. Perhaps call or contact Yamaha and have one of their engineers get a answer for you.
A:AnswerNot sure what a 3.1 setup is
I can tell you I have it attached to 2 Yamaha studio monitors and 2bose bookshelf speakers . It doesn’t seem like I have enough power. Do you have suggestions?
A:AnswerThere is no sub out and no line out for autio you will not be able to hook up a powered sub
But you could use a none powered one with a spk level input the only why u could use a powered sub is with a line amp which has speaker level inputs and hi impedance out
