  • voices leaking to side speaker in 5.1 home theater

    That sounds an awful lot like the center channel bleeding to the mains that would be common in Pro Logic. I'd verify the signal coming in is in fact 5.1 and not 2.0.

      Have you disconnected the Center channel to verify that the dialog is actually coming thru the side speakers?

        What is the content? If you are running older content that was originally a "Dolby Stereo" release (say from the late 70s, 80s or early 90s) the studio's mastering people may have just been lazy and "pro-logic'd" the original 2 channel stereo/surround mix into a "5.1 mix" for DVD/bluray use.

        You will get bleed if the levels between left and right are not absolutely balanced. To demonstrate this, get an original 2 channel source (say from something super awesome like VHS Hi-Fi) and enable your "pro-logic surround" mode. Now disconnect the right channel and you will see everything will jump straight into the surrounds because the DIFFERENCE in left and right is what is sent to the surrounds. The IDENTICAL information is sent to the center.

        Regardless, to answer your question properly, we need to know the movie you are playing and the format (VHS, DVD, bluray, laserdisc, etc) it is sourced from.

          Is it on all disks? Surely you must have something that has a good 5.1 track. Dialogue will nearly always stay on C the majority of the time.
