I have connected my subwoofer to the VSX-AX3 using the front main speaker level outputs of the VSX-AX3 into the subwoofer speaker level inputs. How do I set up the receiver to send all LFE information to the front main speaker outputs as opposed to the dedicated subwoofer RCA output jack? The manual is unclear on this. In the speaker setup, I've got the subwoofer set to 'none'. Does this automatically route LFE information to the left and right front main outputs ?
