SK 48 - external talkback mic

Hey all,

I would like to use an external talkback mic with my SK48.  The manual says to remote the existing talkback channel from the mixer and then add a new one from the 'add channel' button.

When I do this all of the options including 'remote mic' are greyed out and the only way to get the talkback strip back is to load from a previously saved user preset.

Any help appreciated!

Thanks,

Cliff
