Sub Woofer Phase ?


If I am using my pre-out to connect to my sub and the pre-out inverts phase how do I insure correct phase with my main speakers ? I am using a CJ CAV 50 integrated and the pre-out inverts phase but the amp section does not. I am using a Martin Logan Depth sub.

Are you saying that the output from the pre-amp outs is inverted in phase, but the output from the amplifier is not inverted? If so, that means the preamp section inverts phase and so does the amplifier section.

If this is the case, we want to invert the phase of the subwoofer as well.

I think the Depth has a phase control that can be set at 180 degrees. Using this setting would theoretically put the sub back "in phase" with the main speakers.
