Sub Woofer Phase

Hi,

reading through my RX-V667 manual in the setup section it states:


Phase


Sets the phase of the subwoofer if the bass audio is lacking or unclear.


Normal(default) Does not change the subwoofer phase


Reverse Reverses the subwoofer phase.


The thing is I just can not find that specific setting,so I am either missing something or it is not there,any clues please.


Thank you


Sorry wrong post in wrong forum by the looks have put same in Rx-V 667 forum.


I found it in the end................
