Hi, I have recently bought a Q100E from this site.I have hooked this to my Denon 3802.I have a question on this though. Currently all the speakers are set to small and the sub out is connected to the low level input on the sub. Is there any way to connect the high level input on the sub to the receiver? Will that make any difference? Sometimes I feel the sub output is not as much as I would expect,more true for music. Is that normal with the Q100E? I have set the depth option. Additionally, which phase option is better?There are options,and what is the meaning of this phase? Thanks in advance..
