I just got my new receiver in the mail today... Got it all hooked up and now the sub won't work. So I plugged in my old Yamaha receiver and sure enough the sub worked great. I have the cut off dial all the way up on the sub? This is my first Onkyo receiver so I'm wondering if there is a setting that I need to adjust....Could this be as easy as simply redoing the sound check with the microphone, on the off chance that the first time around it didn't pick it up the sub? IDK Thanks for any suggestions.
