Now use the left front and left right "out" on your HT processor and connect those to left and right HT pass-thru "in" on your stereo preamp and remaining channels (C,BR, BL) to amplifier channels for the center, back left and back right channels.
Sorry for that it should say :
Connect the left front channel out and Right front channel out from your HT prepro - to left and right HT pass-thru "in" on stereo preamp.
Don't forget to select HT pass-thru on stereo preamp when you want to watch movies or listen to multichannel music.
Dodd doesn't need to be "ON" but it must be in HT mode. When listening to stereo source, choose the appropriate input on the linestage that corresponds to the source that you want to listen and which is connected to linestage. Volume on linestage is by-passed when in HT mode. For movies use the volume on your HT processor.
Sorry, it is late and I am seeing in double.
Take care
