Home Theater Bypass: The 3rd analog input doubles as a “Home Theater Bypass” so you can have the best of Home Theater and 2-channel in the same system. Simply take the left and right “pre out” from your receiver or processor and connect to the “Home Theater” bypass on the Nova. A selector switch on the back panel converts from Aux to HT bypass. In this application your receiver transparently uses the L&R amplifier section of the Nova, leaving the HT receiver amplifier to push only the center and rear speakers. One, this leaves the receiver responsible only for pushing the center and rear speakers, making the receiver much more efficient and less taxed. And two, when you listen to a 2 channel source plugged directly into the Nova, there’s a straight line from the source to the Nova to the speakers…no processing, no running the signal through a forest of circuitry. This leaves little between the music and your ears. If you’re a 2 channel fan, it’s the only way to do a theater right.
