When I use an AC coupling cap along with a balance line driver, what is the correct setup? What happens when I omit the resistor in the following schematics? Is it neccessary?

I know the way of calculating the filter cut-off point and resistor values, just wondering what happens when I leave the resistor out?

    Andy answered it, but in case it's still not clear to you, if you leave out R1, it's as if you have a 10k resistor to ground.

    Right, I see now that this is a duplicate question although I asked for totally separate reasons. Thanks a lot guys! – jilski Oct 24 '15 at 07:40
