HELP::::::where to on the back panel connect my c40 preamp to a sub...i have a kilpsch rsw 10....thanks
After a quick look at the McIntosh C40 Owner's Manual,
I believe you can connect the kilpsch rsw 10 Line input to either switched output 1or 2 of the C40 and switch on the speaker 1 or 2 accordingly,
k...let me check tonight..thanks
