-play xm thru the line-in. HD radio is not powered unless i'm listening to hd radio
-play hd radio by first muting the xmd1000 then powering on the hd radio
my only fear is that using a splitter will cause some kinda voltage issue. I dont want the voltage on the line from the xm goin back into the hd radio tuner. My original question was will that happen.
Ahhh...I gotcha. I really don't think that you are going to have a voltage issue. I have hooked up two devices in the manner you are describing with no problems at all on several different occasions.
Honestly though, I would just use a switchbox and be on the absolute safe side. I know it isn't as automated as you want, but it will work, and no questions about voltage problems...either that or the uber-expensive sound card option...
